The prevalence of<unk>  depends on the chromosomal content, presence or absence of mosaicism, gonadal histology, and age of the patient and varies between 15,000 to 30,000 per 100,000 individuals worldwide. The incidence of<unk>  varies according to the presence or absence of Y chromosomal content and age of the individual. Patients with Turner syndrome who have Y chromosomal content either completely or partially may develop<unk>  with an incidence as high as 43,000 per 100,000 individuals worldwide. The incidence of<unk>  among phenotypical females with XY gonadal abnormalities have been observed to be 40,000 per 100,000 individuals worldwide.<unk>  may be found at any age, but commonly presents before the age of 15 years. Since, it usually affects individuals with gonadal dysgenesis, there is no genotype-phenotype correlation. Phenotypically, it tends to affect female individuals to a greater extent.
