  • 16. Take-home Messages Evidence for a Positive Impact in the Surgical Treatment of Clinical Varicoceles : 1. Increase the likelihood of spontaneous conception in men with mild/moderate abnormal semen parameters. 2. Increase the odds of live birth in subgroups of men with severe oligozoospermia undergoing ICSI. 3. Increase the chance of having a successful sperm retrieval in the subgroup of patients with non-obstructive azoospermia.Esteves, 16
