Words of wisdom: Re: Does varicocele repair improve male infertility? An evidence-based perspective from a randomized, controlled trial.

摘要

In a prospective, nonmasked, randomized controlled trial, the authors assessed the efficacy of varicocelectomy with the primary outcome of spontaneous pregnancy [1]. The authors examined men with primary or secondary infertility who displayed clinical varicoceles on physical examination and at least one impaired semen parameter on semen analysis. Importantly, authors excluded men with subclinical or recurrent varicoceles or men with normal sperm parameters.
