Abstract
Varicocele is present in approximately 15% of men, and, although it is the most commonly diagnosed cause of male infertility, nearly two-thirds of men with varicoceles remain fertile. It was decided to make use of the current evidence obtained from the previous meta-analyses between 2004 and 2015 as well as available articles covering this field, preferably randomized controlled articles dealing with the topic of semen analysis before and after repair. Two important meta-analyses were discussed as well as other articles dealing with the topic of semen analysis before and after varicocelectomy. The evidence suggests that all semen parameters improve after varicocele repair. Based on the available evidence, it is clear that there is a benefit in treating men with a palpable varicocele. One can expect that all semen parameters will improve within 3 months after repair.
