Can varicocelectomy significantly change the way couples use assisted reproductive technologies?
PURPOSE: We assessed how varicocelectomy alters semen quality in a large cohort of infertile men and determined whether it can change patient candidacy for assisted reproductive technology procedures. MATERIALS AND METHODS: A cohort of 540 infertile men with clinical palpable varicocele underwent microsurgical varicocelectomy and were followed more than 1 and 2 years postoperatively for alterations in semen quality and conception, respectively. Preoperatively and postoperatively the total motile sperm count was calculated in all semen analyses. Based on total motile sperm count values patients were divided into 4 groups according to the type of assisted reproductive technology for which they qualified, including 0 to 1.5 million or less (intracytoplasmic sperm injection candidates), 1.5 to 5 million or less (in vitro fertilization candidates), 5 to less than 20 million (intrauterine insemination candidates) and 20 million or greater sperm (spontaneous pregnancy candidates).
