OBJECTIVE To evaluate the effect of preimplantation genetic screening ( PGS ) on neurodevelopmental outcomes in children . DESIGN Prospect i ve , assessor-blinded , follow-up study of children born to women r and omly assigned to in vitro fertilization or intracytoplasmic sperm injection ( IVF/ICSI ) with or without PGS .  SETTING University Medical Center , Groningen , and Academic Medical Center , Amsterdam , the Netherl and s. PATIENT(S ) Fifty-four PGS children and 77 controls .  INTERVENTION(S ) PGS . MAIN OUTCOME MEASURE(S ) Mental , psychomotor , neurologic , and behavioral outcomes in 2-year-old children  as measured with the Bayley Scales of Infant Development , the Hempel neurologic examination , and the Child Behavior Check List . RESULT ( S ) The mental , psychomotor , and behavioral outcomes at 2 years in children born after IVF with and without PGS were similar overall . The PGS children showed lower neurologic optimality scores than the control children . Scores on all tests were within the normal range . CONCLUSION ( S ) Conception with PGS does not seem to be associated with impaired mental , psychomotor , or behavioral outcomes by age 2 . However , the lower neurologic optimality scores found in the PGS children may signal less favorable long-term neurologic outcomes in PGS children . Our findings stress the need for safety evaluations with new assisted reproductive techniques before large-scale implementation Long-term follow-up studies on the health of children born after assisted reproduction technologies  are m and atory . Vision and hearing are the most important senses that continue to develop during childhood . There are few reports on vision and hearing in preschool children born after assisted conception . This prospect i ve controlled blinded follow-up study examined 276 term-born singleton intracytoplasmic injection ( ICSI ) children and 273 spontaneously conceived controls at a mean age of 5.5 years and performed detailed  vision and hearing test and clinical ly examined eyes and ears . There was no significant difference between ICSI and control children regarding the occurrence of vision or hearing impairments . Unsurprisingly , children with abnormalities in otoscopy were more likely to have an abnormal hearing test compared with children without abnormalities . Only 8.5 % of ICSI parents and 25.4 % of control parents whose children showed an abnormal hearing test knew about the hearing problems of their child . In conclusion , there was no difference in the development of hearing and vision in ICSI children and spontaneously conceived controls . But only few parents knew about hearing problems of their child after undergoing routine screening examinations . Parental interviews would therefore not be sufficient in order to assess vision and hearing in follow-up studies Abstract Objective To compare neurological sequelae in twins born after assisted conception with singletons after assisted conception and naturally conceived twins and to assess neurological sequelae in children conceived after in vitro fertilisation ( IVF ) compared with intracytoplasmic sperm injection ( ICSI ) .  Design Controlled , national register based , cohort study . Participants Twins ( n = 3393 ) and singletons ( n = 5130 ) conceived by using assisted reproductive technologies and naturally conceived twins ( n = 10 239 ) born in Denmark between 1995 and 2000 . The children 's age at time of follow up was 2 - 7 years . Data sources Children were identified by cross linkage of the national medical birth registry and the national registry for in vitro fertilisation . Neurological and psychiatric diagnoses were retrieved from the national patients ' registry and the Danish psychiatric central registry . Main outcome measures Neurological sequelae , defined as cerebral palsy , mental retardation , severe mental developmental disturbances , and retarded psychomotor development . Further we made separate analyses on the specific cerebral palsy diagnosis . Results The crude prevalence rates per 1000 of neurological sequelae in twins and singletons after assisted conception and in naturally conceived twins were 8.8 , 8.2 , and 9.6 , and of cerebral palsy 3.2 , 2.5 , and 4.0 , respectively . In twins after assisted conception compared with control twins , the odds ratios of neurological sequelae and specifically of cerebral palsy , adjusted for child sex and year of birth , were 0.9 ( 95 % confidence interval 0.6 to 1.4 ) and 0.8 ( 0.4 to 1.6 ) , respectively . The corresponding odds ratios for twins after assisted conception compared with singletons after assisted conception were 1.1 ( 0.7 to 1.7 ) for neurological sequelae and 1.3 ( 0.6 to 2.9 ) for cerebral palsy . The odds ratio of neurological sequelae in children conceived by ICSI was 0.9 ( 0.5 to 1.7 ) ν children conceived by IVF . Conclusions Twins from assisted conception have a similar risk of neurological sequelae as their naturally conceived peers and singletons from assisted conception . Children born after ICSI have the same risk of neurological sequelae as children born after IVF Objective To assess the mental health of children born after fertility treatment  by comparing their risk of mental disorders with that of spontaneously conceived children . Design Prospect i ve register based cohort study . Setting Nationwide register based information from Danish National Health Registers cross linked by a unique personal identification number assigned to all citizens in Denmark . Participants All children born in Denmark in 1995 - 2003 with follow-up in 2012 when the children were aged 8 - 17 ; 33 139 children were conceived after fertility treatment and 555 828 children were born after spontaneous conception .  Main outcome measures Absolute risks and hazard ratios for overall and specific mental disorders estimated with adjustment for potential confounding variables . Estimated association between the risk of mental disorders and subtypes of procedures , hormone treatments , gamete types , and cause of infertility . Results The risk of mental disorders in children born after in vitro fertilisation or intracytoplasmic sperm injection was low , and was no higher than in spontaneously conceived children , except for a borderline significant increased risk of tic disorders ( hazard ratio 1.40 , 95 % confidence interval 1.01 to 1.95 ; absolute risk 0.3 % ) . In contrast , children born after ovulation induction with or without insemination had low but significantly increased risks of any mental disorder ( 1.20 , 1.11 to 1.31 ; absolute risk 4.1 % ) , autism spectrum disorders ( 1.20 , 1.05 to 1.37 ; 1.5 % ) , hyperkinetic disorders ( 1.23 , 1.08 to 1.40 ; 1.7 % ) , conduct , emotional , or social disorder ( 1.21 , 1.02 to 1.45 ; 0.8 % ) , and tic disorders ( 1.51 , 1.16 to 1.96 ; 0.4 % ) . There was no risk systematic ally related to any specific type of hormone drug treatment . Conclusions There was a small increase in the incidence of mental disorders in children born after ovulation induction/intrauterine insemination . Children born after in vitro fertilisation/intracytoplasmic sperm injection were found to have overall risk comparable with children conceived spontaneously BACKGROUND Due to the growing number of children born following assisted reproduction technology  , even subtle changes in the children 's health and development are of importance to society at large . The aim of the present study was to evaluate the specific effects of ovarian hyperstimulation and the in vitro procedure on neurological outcome in 4 - 18-month-old children . METHODS In this prospect i ve assessor-blinded cohort study , we included singletons born following controlled ovarian hyperstimulation in vitro fertilization ( IVF ) or intracytoplasmic sperm injection ( ICSI ) ( COH-IVF ; n = 68 ) or modified natural cycle-IVF/ICSI ( MNC-IVF ; n = 57 ) or naturally conceived singletons of subfertile couples ( NC ; n = 90 ) . Children were assessed with st and ardized , age-specific and sensitive neurological assessment s ( TINE and Hempel assessment ) at 4 , 10 and 18 months . Neurological examination result ed in a neurological optimality score ( NOS ) , a fluency score and a clinical neurological classification . Fluency of movements is easily affected by neurological dysfunction and is therefore a sensitive measure for minimal changes in neuromotor development . RESULTS The NOS and the fluency score were similar in COH-IVF , MNC-IVF and NC children . None of the children showed major neurological dysfunction and rates of minor neurological dysfunction at the three ages were not different between the three conception groups . CONCLUSIONS We found no effects of ovarian hyperstimulation or the in vitro procedure itself on neurological outcome in children aged 4 - 18 months . The findings of our study are reassuring , nevertheless it should be kept in mind that subtle neurodevelopmental disorders may emerge when children grow older . Continuation of follow-up in older and larger groups of children is therefore still needed Objective To investigate how pregnancy planning , time to conception , and infertility treatment influence cognitive development at ages 3 and 5 . Design Prospect i ve population based cohort study . Setting Millennium Cohort Study in the United Kingdom . Participants 18 818 children recruited at 9 months and followed up at 3 and 5 years . 11 790 singletons with available data on pregnancy , cognitive outcomes , and confounders were included in analyses at age 3 and 12 136 at age 5 . Exposure measures Mothers reported whether the pregnancy was planned , and their feelings when first pregnant ; those in whom the pregnancy was planned provided time to conception , and details of any assisted reproductive technologies . The population was divided into “ unplanned ” ( unplanned and unhappy ) , “ mistimed ” ( unplanned but happy ) , “ planned ” ( planned , time to conception < 12 months ) , “ subfertile ” ( planned , time to conception ≥12 months ) , “ induced ovulation ” ( received clomiphene citrate ) , and “ assisted reproduction ” ( in vitro fertilisation or intracytoplasmic sperm injection ) . The “ planned ” group was the comparison group in all analyses . Outcome measures Three components of the British Ability Scales ( BAS II ) . Naming vocabulary assessed verbal ability at age 3 ; this test was repeated at age 5 with the picture similarities and pattern construction subscales , which measure non-verbal and spatial abilities . Results In unadjusted analyses , the scores on all scales in children from unplanned pregnancies were significantly lower than in those from planned pregnancies — for example , the difference in mean verbal ability score at age 3 was −4.8 ( 95 % confidence interval −6.0 to −3.7 ; P<0.05 ) , equivalent to an average delay of four months . After adjustment for sociodemographic factors these differences were attenuated : −0.3 ( −1.3 to 0.7 ) , equivalent to no delay . Children born after assisted reproduction performed consistently better in verbal ability tests ( 3.8 ( −0.2 to 7.9 ) at age 3 and 3.5 ( 0.2 to 6.8 ) at age 5 ) , which suggests that on average these children are three to four months ahead ; this difference did not completely disappear with adjustment for confounders . Children born after infertility treatment had lower mean scores in non-verbal tests ( −1.2 ( −4.1 to 1.6 ) after assisted reproduction and −1.5 ( −3.5 to 0.4 ) after induced ovulation ) and in spatial ability tests ( −2.7 ( −6.9 to 1.6 ) after assisted reproduction ) , though the differences were not significant . Conclusions Pregnancy planning , subfertility , or assisted reproduction do not adversely affect children ’s cognitive development at age 3 or 5 . The differences observed in the unadjusted analyses are almost entirely explained by marked inequalities in socioeconomic circumstances between the groups Recent studies have given conflicting results regarding growth in children born following assisted reproductive treatments up to the age of 18years . It has been suggested that children conceived via IVF may be taller than naturally conceived children and that this may due to subtle epigenetic alteration of imprinted genes as a result of the IVF process . A prospect i ve match-controlled study was performed to investigate the growth of children born in the UK following st and ard IVF and intracytoplasmic sperm injection ( ICSI ) up to the age of 12years . The study assessed 143 IVF and 166 ICSI children with 173 matched naturally conceived controls . Primary end-points were height and weight at various time points : birth , 5years , 7 - 9years and 10 - 12years . In addition , head circumference was assessed at birth . No significant differences were observed regarding head circumference , height and weight between the three groups at any of the time points . In conclusion , this preliminary study provides reassuring information regarding the growth of  IVF and ICSI children up to 12years . Further studies must continue to investigate the growth and other outcomes in assisted-conception children as they develop through puberty into early adulthood OBJECTIVE To assess the neurodevelopmental health of children born after intracytoplasmatic sperm injection ( ICSI ) .  DESIGN Prospect i ve controlled blinded study . SETTING Tertiary care center . PATIENT(S ) A total of 276 term-born singletons conceived by ICSI and 273 matched spontaneously conceived ( SC ) singletons at the age of 5.5 years . MAIN OUTCOME MEASURE(S ) Neuromotor development assessed by a detailed neurologic examination , including the st and ardized motor test MOT 4 - 6 , and emotional/behavioral development and intelligence assessed with the Kaufman- Assessment Battery for Children . RESULT ( S ) There were no significant differences between ICSI children and control children regarding the neurologic examination , motor skills , emotional/behavioral development , and intelligence . CONCLUSION ( S ) The ICSI children born at term develop normally , similar to SC children OBJECTIVE To determine pregnancy course and major malformation rate  after intracytoplasmic sperm injection ( ICSI ) .  DESIGN Prospect i ve , controlled , multicenter , nationwide German cohort study . SETTING Tertiary infertility centers in Germany . PATIENT(S ) Three thous and three hundred seventy-two children and fetuses and 8,016 children and fetuses after the 16th week of gestation in pregnancies after ICSI and natural conception , respectively . INTERVENTION(S ) St and ardized prospect i ve follow-up . MAIN OUTCOME MEASURE(S ) Major malformation rate . RESULT ( S ) The major malformation rate was 8.7 % ( 295/3,372 ) for the ICSI cohort and 6.1 % ( 488/8,016 ) for the population -based control cohort ( relative risk , 1.44 [ 1.25 - 1.65 ] ) . After adjustment for risk factors , the risk declined ( adjusted odds ratio , 1.24 [ 95 % CI , 1.02 - 1.50 ] ) . Regarding singletons , there was a significant difference for birth weight and gestational age , with a higher number of preterm and low birth weight children in pregnancies achieved after ICSI . CONCLUSION ( S ) Children who are born after intracytoplasmic sperm injection have an increased risk of a major congenital malformation compared with those born after spontaneous conception . This risk is mainly due to paternal and maternal risk factors , which are more prevalent in couples who use ICSI for reproduction . An infertility-linked risk is highly probable for the observed findings . A technique-related risk , however , can not be ruled out Aim of this study was to evaluate the effect of preimplantation genetic screening ( PGS ) on  neurodevelopmental outcome in children . We conducted a prospect i ve follow-up study of children born to women r and omly assigned to in vitro fertilization with or without PGS .  Primary outcome was adverse neurologic outcome at 18 mo ; secondary outcomes were types of minor neurologic dysfunction ( MND ) , neurologic outcome before 18 mo , neonatal intensive care admission , and congenital malformations .  Twenty women in the PGS group participated with 25 children and 26 women in the control group participated with 31 children . Five PGS pregnancies ( 25 % ) and four control pregnancies ( 15 % ) result ed in birth of at least one child with an adverse neurologic outcome ( adjusted odds ratio : 2.3 [ 0.4–12.0 ] ) . Dysfunction in fine motor abilities and posture and muscle tone dysregulation tended to be present more frequently after PGS .  Neurologic outcome before 18 mo , neonatal intensive care admission , and prevalence of congenital malformations were similar in study and control pregnancies . Nevertheless , at child level , rates of adverse outcome were higher after PGS . In conclusion , outcome in pregnancies after in vitro fertilization ( IVF ) with and without PGS was similar . The small sample size precludes the conclusion that PGS is not associated with less favorable neurologic outcome . Safety of new assisted reproductive techniques should be evaluated before large-scale implementation STUDY QUESTION Does ovarian hyperstimulation , the in vitro procedures required for in vitro fertilization (IVF)/ intracytoplasmic sperm injection or the combination of both , affect the  neurological outcome  of 4-year-old singletons ? SUMMARY ANSWER Ovarian hyperstimulation , the in vitro procedure and the combination of both , were not associated with the worse neurological outcome in 4-year-old singletons . WHAT IS KNOWN ALREADY Assisted reproduction techniques ( ARTs ) are not associated with neurological dysfunction during the first post-natal years ; however , effects on the long-term neurological outcome are still inconclusive . An increased time to pregnancy ( TTP , a proxy for the severity of subfertility ) has been associated with a less optimal neurological condition at age 2 . The present study focuses on the neurodevelopmental outcome of 4-year-old ART-offspring . STUDY DESIGN , SIZE , DURATION Longitudinal , prospect i ve follow-up study . PARTICIPANTS , SETTING , METHODS Four-year-old singletons born to subfertile parents ( subfertile group , n = 195 ) , including singletons born after controlled ovarian hyperstimulation IVF ( COH-IVF , n = 63 ) , modified natural cycle IVF ( MNC-IVF , n = 53 ) and natural conception ( Sub-NC , n = 79 ) . Data on underlying cause of subfertility and TTP were present . In addition , we assessed newly recruited 4-year-old singletons born to fertile parents after natural conception ( reference group , n = 98 ) . Neurological development was evaluated with the neurological examination according to Hempel , result ing in a neurological optimality score ( NOS ) , a fluency score and the occurrence of the clinical ly relevant form of minor neurological dysfunction ( complex MND ) . The primary outcome was the fluency score , as fluency of movements is easily reduced by subtle brain dysfunction . Data were analysed with univariable and multivariable regression analyses , in which special attention was paid to sex differences in the neurological outcome . MAIN RESULTS AND THE ROLE OF CHANCE The fluency score , NOS and the prevalence of complex MND were similar in COH-IVF , MNC-IVF and Sub-NC children . The neurological condition of children born to subfertile parents was similar to that of children of fertile parents and was independent of the underlying cause of subfertility . No statistically significant associations were found between TTP and the fluency score and NOS . However , a positive correlation was found between TTP and the prevalence of complex MND ( TTP in years , adjusted odds ratio [ OR ] [ 95 % confidence interval , CI ] : 1.207 [ 1.038 to 1.404 ] , P = 0.014 ) ; a correlation which could be attributed to girls , in whom an evident positive correlation was present ( adjusted OR [ 95 % CI ] : 1.542 [ 1.161 to 2.047 ] , P = 0.003 ) . A similar association was absent in boys . LIMITATIONS , REASONS FOR CAUTION The prospect i ve design of our study and small post-natal attrition rate ( 9.3 % ) reduced potential selection bias based on the child 's development or health . The assessors were blind to the mode of conception , except for the group of children born to fertile parents , which was newly recruited . The study lacks sufficient power to conclude firmly that increased TTP is associated with a higher prevalence of complex MND . WIDER IMPLICATION S OF THE FINDINGS Our study suggests that the severity of subfertility , rather than its simple presence or components of IVF treatment , affects the neurological outcome . Moreover , girls may be neurologically more vulnerable for the effect of severity of subfertility . The finding that the severity of subfertility may be the decisive factor rather than the presence of a history of subfertility per se corroborates previous reports . Our results can not be generalized to multiples , as we studied singletons only . STUDY FUNDING /COMPETING INTERESTS The study was financially supported by the University Medical Center Groningen , grant number : 754510 , the Junior Scientific Masterclass , the Postgraduate School Behavioural and Cognitive Neurosciences and the Cornelia Foundation , Groningen , The Netherl and s. The authors have no conflicts of interest to declare STUDY QUESTION Do preschool preimplantation genetic diagnosis ( PGD ) children differ in their cognitive and psychomotor development from children born after ICSI and spontaneous conception ( SC ) ? SUMMARY ANSWER The cognitive development of PGD pre-schoolers was comparable to children born after ICSI and SC but motor development differed between ICSI and SC groups . STUDY DESIGN , SIZE DURATION The cognitive abilities and motor skills of 5- to 6-year-old singletons born after PGD ( n = 47 ) were assessed in comparison with 49 ICSI and 48 SC children in a prospect i ve , case-controlled , matched follow-up study between April 2011 and May 2013 . PARTICIPANTS / MATERIAL S , SETTING , METHODS PGD singletons , ICSI and SC children of preschool age were examined with the Wechsler Preschool and Primary Scale of Intelligence ( WPSSI-III-NL ) and the Movement ABC ( M ABC ) . The WPSSI-III-NL revealed scores for Full IQ , Verbal IQ and Performance IQ . The M ABC yields a total score and comprising scores for measurements of balance , dexterity and ball skills . Since embryo biopsy is the only technical difference between the PGD and ICSI procedures , ICSI children were included as controls . These children were part of a Dutch-speaking cohort of children conceived after assisted reproduction technology ( ART ) at the Universitair Ziekenhuis Brussel ( UZ Brussel ) who received longitudinal follow-up . The SC children acted as a second control group similar to the fertile PGD sample and in contrast to the ICSI group . The SC group was recruited through announcements in a variety of media . The children were matched for age , gender , birth order and educational level of the mother . The assessment s carried out for the ART groups were blinded whenever possible . The data were analysed using analysis of covariance ( ANCOVA ) and partial eta squared ( η(2 ) ) , which was used as a measurement of effect size . MAIN RESULTS AND THE ROLE OF CHANCE The overall cognitive development of PGD singletons did not differ from controls [ P = 0.647 , η(2 ) = 0.006 ; 95 % confidence interval ( CI ) ( 0 , 0.043 ) ] . The partial IQ scores for Verbal and Performance intelligence revealed similar results . Analysis of motor development based on the total score as well as subscales did indicate a significant difference between the three conception groups [ P = 0.033 , η(2 ) = 0.050 , 95 % CI ( 0 , 0.124 ) ] . Post hoc analysis indicated that the significant difference was situated between performances of ICSI and SC children . Balance capacities [ P = 0.004 , η(2 ) = 0.079 , 95 % CI ( 0.025 , 0.163 ) ] and its post hoc analysis yielded equivalent results . Motor capacities of PGD singletons , however , did not differ from any of the two other conception groups . LIMITATIONS , REASONS FOR CAUTION Given that we only assessed Caucasian singletons born after PGD , caution is required when drawing more general inferences from our results . The small sample size may be a limitation . A priori power analysis , however , revealed that at least 52 children per group were needed to detect a medium effect and 80 % power using ANCOVA . Originally our sample met this threshold but we had to exclude six cases in order to remove outliers and due to missing data . WIDER IMPLICATION S OF THE FINDINGS Long-term follow-up of children born after embryo biopsy , in this case for PGD , is needed to confirm that the development of these children remains comparable to ICSI and SC children . Our findings do support the safety of the PGD technique and will reassure patients with hereditary genetic diseases regarding the health of their future offspring conceived with PGD . STUDY FUNDING /COMPETING INTERESTS Funding for this study was obtained from the OZR ( Research group of the Vrije Universiteit Brussel ) , the FWO ( Fonds Wetenschappelijk Onderzoek ) and the Wetenschappelijk Fonds Willy Gepts . The UZ Brussel and the Centre of Medical Genetics received funding from pharmaceutical firms for data collection . UZ Brussel and the Centre for Medical Genetics have received many educational grants for organizing the data collection , from IBSA , Ferring , Organon , Shering-Plough , Merck and Merck Belgium . M.B. has received consultancy and speaker 's fees from Organon , Serono Symposia and Merck We have studied from birth up to the 3rd year the psychological attitude of 33 in-vitro fertilization ( IVF ) children compared to two other groups : children born after ovarian stimulation without IVF ( n = 33 ) and children conceived naturally ( n = 33 ) during the same period . Fourteen children , born by oocyte donation , were also studied by the same methodology . In the IVF group , we found some feeding difficulties and sleep disorders in the infants at 9 months and some signs of depression in mothers . All these symptoms disappeared afterwards . The development of all the children is satisfactory and the relationship with their mother is excellent . In this preliminary study , we conclude that the method of assisted reproduction has no bad influence on the psychomotor development of these children A case-referent study of birth defects was nested in a prevalence survey of adverse reproductive outcomes carried out among 8867 floriculture workers in Bogotá , Colombia . A total of 535 children born to these workers and reported by their parents as malformed and 1070 children selected at r and om as referents were invited to a medical examination including consultation with a geneticist and a clinical teratologist and a review of the medical records . Seventy-six percent of both groups attended the examination . Of 403 children reported as malformed , a birth defect was confirmed for only 154 ( 38 % ) . On the other h and , of the 817 children reported as normal , 735 ( 90 % ) were normal , but 68 had a birth defect and 14 had other conditions . A case-referent analysis was then carried out including 222 children with birth defects and 443 referents . An increased risk was found only for birthmarks , and specifically for hemangiomas , for children with parents exposed to pesticides in the floriculture industry Background —Acupuncture has recently been studied in assisted reproductive treatment ( ART ) although its role in reproductive medicine is still debated . Objectives —To determine the effectiveness of acupuncture  in the outcomes of ART . Search strategy —All reports which describe r and omised controlled trials of acupuncture in assisted conception were obtained through search es of the Menstrual Disorders and Subfertility Group Specialised Register , CENTRAL , Ovid MEDLINE ( 1996 to August 2007 ) , EMBASE ( 1980 to August 2007 ) , CINAHL ( Cumulative Index to Nursing & Allied Health Literature ) ( 1982 to August 2007 ) , AMED , National Research Register , Clinical Trials register ( www . clinical trials.gov ) , and the Chinese data base of clinical trials . Selection Criteria —R and omised controlled trials of acupuncture for couples who were undergoing ART comparing acupuncture treatment alone or acupuncture with concurrent ART versus no treatment , placebo or sham acupuncture plus ART for the treatment of primary and secondary infertility . Women with medical illness deemed contraindications for ART or acupuncture were excluded . Data Collection and Analysis —Sixteen r and omised controlled trials were identified that involved acupuncture and assisted conception . Thirteen trials were included in the review and three were excluded . Quality assessment and data extraction were performed independently by two review authors . © 2010 Elsevier Inc.

NIH Public OBJECTIVE To evaluate whether children 's  cognitive and psychomotor development and behavior at 2 years are affected by ovarian hyperstimulation and the IVF laboratory procedures or subfertility . DESIGN Prospect i ve longitudinal cohort study . SETTING University Medical Center Groningen , the Netherl and s. PATIENT(S ) Singletons born after controlled ovarian hyperstimulation (COH)-IVF ( n=66 ) and modified natural cycle-IVF ( n=56 ) , singletons born to subfertile couples who conceived naturally ( subfertile-naturally conceived , n=87 ) , and a reference group of 101 2-year-old singletons born to fertile couples . INTERVENTION(S ) None . MAIN OUTCOME MEASURE(S ) Bayley Scales of Infant Development and Achenbach Child Behavior Checklist . RESULT ( S ) Mental and psychomotor development and behavioral outcome in COH-IVF , modified natural cycle-IVF , and subfertile-natural cycle groups was not different . Developmental outcome and behavior of the subfertile groups were largely similar to those of the fertile reference group . Nevertheless , the subfertile groups scored higher on the scale of anxious-depressed behavior than the reference group . CONCLUSION ( S ) This present relatively small study found no differences in cognitive and psychomotor development and behavior at 2 years in children born after COH-IVF or modified natural cycle-IVF or naturally conceived children of subfertile parents . Replication of the study is needed before firm conclusions can be drawn . Furthermore , long-term follow-up is needed to confirm these findings in older children Four-Year Follow-up of Children Born to Women in a R and omized Trial of Prenatal DHA Supplementation Despite the paucity of evidence , recommendations exist internationally for pregnant women to increase their docosahexaenoic acid ( DHA ) intake to optimize fetal brain development . Our r and omized controlled trial ( RCT ) , in which pregnant women were allocated to 800 mg/d of DHA or matched placebo , showed that children ’s mean cognitive , language , and motor scores did not differ between groups at 18 months , although fewer children in the DHA group had delayed development compared with controls.1 Surprisingly , girls in the DHA group had poorer language scores than girls in the control group.1 Herein we report neurodevelopmental outcomes at 4 years , which is when any subtle to moderate effects on development should have emerged and can be more reliably assessed BACKGROUND As a continuation of two large-scale , multicentre studies on the development of 5-year-old ICSI children , we present results of the follow-up study undertaken on the cognitive and motor development of 8-year-old ICSI children . METHODS Developmental outcomes of 151 8-year-old singletons born through ICSI after 32 weeks of gestation were compared with those of 153 singletons of the same age born after spontaneous conception ( SC ) . Part of this population was seen in a cohort at the age 5 years . Outcome measures include Wechsler Intelligence Scale for Children-Revised ( WISC-R ) and Movement Assessment Battery for Children ( ABC ) . RESULTS Regarding intellectual functioning , ICSI children tend to obtain significantly higher total ( P < 0.01 ) , verbal ( P < 0.01 ) and performance ( P < 0.05 ) intelligence scores than SC children , nevertheless remaining in similar ranges . These effects are small ( Cohen 's d < 0.50 ) . High maternal educational level stayed in the regression as a factor accounting for some of the variance in total IQ between the groups . In terms of motor development , no significant differences were found between ICSI and SC children regarding overall motor skills , manual , balance and ball skills . CONCLUSION In this follow-up study , ICSI and SC children show a comparable cognitive and motor development until the age of 8 years STUDY QUESTION Do children born after assisted reproductive techniques ( ART ; IVF/ICSI )  display more mental health issues or social and cognitive developmental problems at 7 - 8 years than naturally conceived ( NC ) controls , and does child gender play a role ? SUMMARY ANSWER ART children do not differ with regard to mental health or social and cognitive developmental problems when compared with controls , but some gender-specific differences do exist . WHAT IS KNOWN ALREADY Systematic review s have not found any evidence of delays in neurocognitive or sensorimotor development in ART children . However findings on the effect of the type of ART treatment ( IVF versus ICSI ) on the offspring 's physical and mental development have not been uniform . Knowledge of the role of child gender in ART research is scarce . STUDY DESIGN , SIZE , DURATION This prospect i ve follow-up study compares mental health and social and cognitive developmental problems between 7 - 8-year-old ART and NC children , controlling for the father 's age , length of the parents ' partnership , mother 's parity , child 's gestational age , and the need of neonatal intensive care unit ( NICU ) . Further , within the ART group , we analysed whether the treatment type ( IVF versus ICSI ) and the child 's gender are associated with the mental health and developmental outcomes . PARTICIPANTS / MATERIAL S , SETTING , METHODS In this study , 255 singleton ART children ( IVF and ICSI ) were compared with 278 NC children on parent-reported internalizing and externalizing symptoms , and social ( social skills and peer relations ) and cognitive development ( executive functioning , perception , memory , and language ) . Within the ART group , 164 IVF and 76 ICSI children were compared on the same outcomes . Statistics included analyses of covariates ( ANCOVA ) with group main effects , group and gender interaction effects , and Bonferroni post hoc tests . MAIN RESULTS AND THE ROLE OF CHANCE ART and NC children did not differ generally in terms of their internalizing and externalizing symptoms or in the number of social and cognitive developmental problems ( Group main effects , P > 0.05 ) , but gender-specific group differences existed . The ART boys showed lower levels of cognitive problems than the NC boys , whereas ART girls showed higher levels of cognitive problems than the NC girls ( Group × Gender-interaction effects with Bonferroni post hoc tests on mother-reports , P < 0.01 ) . Further , unlike in the NC group , where boys showed more externalizing symptoms and social and cognitive developmental problems than girls ( Group × Gender-interaction effects with Bonferroni post hoc tests for both parents ' reports , P < 0.05 ) , gender differences were not found in the ART group . Within the ART group , IVF and ICSI children did not differ in terms of mental health or developmental outcomes , and no significant gender differences emerged . LIMITATIONS , REASONS FOR CAUTION The information on children 's mental health and development was based on parental reports only . The dropout rate between the child 's first year and the school age assessment s was very high for fathers ( 57.4 % ) and substantial for mothers ( 30.1 % ) , and the participating group was biased for older age of both parents and for better education of the fathers . WIDER IMPLICATION S OF THE FINDINGS The findings indicate the importance of considering child gender in learning about multiple developmental outcomes among children born after ART .

RESULT ( S ) For infants , studies on psychomotor development showed no deficits , but few investigated cognitive or behavioral development .
Studies on toddlers generally reported normal cognitive , behavioral , socio-emotional , and psychomotor development .
For children in middle childhood , development seems comparable in children born after assisted reproduction and controls , although fewer studies have been conducted with follow-up to this age .
( S ) It may tentatively be concluded that the neurodevelopment of children born after  fertility treatment  is overall comparable to that in children born after spontaneous conception
OBJECTIVE To systematic ally review the existing literature on neurodevelopmental outcomes in children born after medically assisted reproduction  compared with those of children born after spontaneous conception .
