Prolactin Levels & Prolactin Testing. Prolactin is a hormone that plays a role in fertility by inhibiting follicle stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH), the hormones that trigger ovulation and allow eggs to develop and mature.
(The exception is a molar pregnancy, which may require that you wait six months to a year before trying again.) A study published in 2015 looked at women in four health centers around the U.S. who were trying to conceive after a pregnancy loss.
When does conception occur? Yes, in general you have just 24 hours to conceive, but some preparations for conception start much earlier, approximately 5-7 days before ovulation. Spermatozoa, which have got inside the uterus or Fallopian tubes, can wait for ovulation from several hours up to 7 days!
