Vasectomy reversal (VR) has traditionally been performed with the operative microscope. Recently, robot assistance has been applied to VR. Retrospective chart review from a single VR center included men who underwent either robot-assisted VR (RAVR) or microsurgical VR (MVR) by a single fellowship trained microsurgeon between 2011 and 2013 and had a 6 weeks postoperative semen analysis. Fifty-tw...

mately 500,000 procedures performed annually.1,2 Of these men, 2% to 6% will desire reversal of their vasectomy at a later time.3 Reasons include re-marriage, desire for further fertility, loss of a child, and chronic testicular pain. Vasectomy reversal can be performed in a variety of ways. Both macroand microsurgical techniques have been described and are currently being used by practicing ur...

Vasectomy reversal by vasovasostomy after long-term vasectomy in men results in lower sperm counts and pregnancy rates compared with controls, and severe damage to spermatogenesis has been observed in some animal models such as mice. The primary aim of this study was to evaluate, using sophisticated stereological methods, whether vasectomy of 6 and 12 months in a non-human primate would lead to...

PURPOSE We determined whether men who may have partial obstruction and antisperm antibodies after vasovasostomy can be distinguished from other infertile men with antisperm antibodies only, and whether repeat microsurgical reversal is beneficial in such patients. MATERIALS AND METHODS A total of 412 patients underwent indirect immunobead testing for antisperm antibodies at our laboratory from...

Only a small minority of women who are protected by contraceptive sterilization express regret about that method choice, regardless of whether they or their husbands have had the surgery, according to findings from a prospective, multicenter study.1 Within five years after their husbands’ vasectomy, 6% of women indicated that it was not a good choice; essentially the same proportion of steriliz...

Vasectomy is a simple and reliable method of male contraception. A growing number of men after vasectomy request vasectomy reversal due to various reasons. The pregnancy rate is lower than the patency rate after vasovasostomy and the pregnancy rate is time dependent. In this study, we evaluated the influence of reproductive tract obstruction on expression of epididymal proteins and their restor...

The mammalian epididymis is a fundamental organ for sperm cell maturation; it allows mammals to acquire their fertilizing ability. We have previously shown that during obstruction in cases of vasectomy, gene expression profiles were modified in human and cynomolgus monkey epididymides. Paracrine factors thus appear to be key elements in local gene expression along the epididymis. Local renin-an...
