6,8,23 A high FSH level (10 to 20 mIU per mL [10 to 20 IU per L]) drawn on day 3 of the menstrual cycle is associated with infertility. Additionally, because insulin-like growth factor (IGF) has been shown to have an effect on semen quality, its role in varicocele pathology has been studied.[25] One study showed that IGF levels significantly increased after a varicocelectomy to levels that were no different than fertile controls, suggesting that varicocele-related infertility may involve IGF.[26] Varicoceles lead to an increased incidence of sperm immaturity, apoptosis, and necrosis with severe disturbances in meiotic segregation compared to fertile men without varicoceles, and these parameters generally improve after repair. The fertilized embryo is then transferred to womb. In-vitro fertilization and donor insemination are major procedures involved.

It is increasingly recognized that egg quality is of critical importance and women of advanced maternal age have eggs of reduced capacity for normal and successful fertilization. The resulting sperm count (also called spermiogram) allows identifying various pathologies.
