  • Title: The Role of Varicocele in Male Factor Subfertility.
    Author: Sedaghatpour D, Berookhim BM.
    Journal: Curr Urol Rep; 2017 Sep; 18(9):73. PubMed ID: 28718159.
    Abstract:
    PURPOSE OF REVIEW: Varicocele may play a significant role in a subset of patients presenting with male factor infertility. Despite its relatively high prevalence amongst subfertile men, there has been controversy over the effectiveness of surgical treatments, patient selection, and when to administer treatment, particularly in the era of assisted reproductive technology. RECENT FINDINGS: In line with earlier finding, recent evidence strongly suggests that varicocelectomy improves pregnancy rates and semen parameters. The currently available literature still does not clearly elucidate the answer to this question, due to flaws in retrospective study design. Patients undergoing subinguinal microsurgical varicocelectomy appear to have the highest pregnancy rates, and lowest complication rates, compared to other surgical approaches. Current research has given us a better understanding of the relationship between varicocele and infertility. Amongst men presenting with semen analysis abnormalities and varicoceles, including those patients presenting with non-obstructive azoospermia or couples with a significant male factor component failing previous attempts at in vitro fertilization, varicocelectomy may improve take home baby rates. More robust, prospective, controlled studies are needed to further clarify the population of subfertile men with varicocele most likely to benefit from varicocelectomy.
