Vasectomy: An Update - Article
ABSTRACT: Vasectomy remains an important option for contraception. Research findings have clarified many questions regarding patient selection, optimal technique, postsurgical follow-up, and risk of long-term complications. Men who receive vasectomies tend to be non-Hispanic whites, well educated, married or cohabitating, relatively affluent, and have private health insurance. The strongest predictor for wanting a vasectomy reversal is age younger than 30 years at the time of the procedure. Evidence supports the use of the no-scalpel technique to access the vasa, because it is associated with the fewest complications. The technique with the lowest failure rate is cauterization of the vasa with or without fascial interposition. The ligation techniques should be used cautiously, if at all, and only in combination with fascial interposition or cautery. A single postvasectomy semen sample at 12 weeks that shows rare, nonmotile sperm or azoospermia is acceptable to confirm sterility. No data show that vasectomy increases the risk of prostate or testicular cancer.
Vasectomy Techniques - Article
ABSTRACT: Vasectomy can be performed by means of various techniques, although each vasectomy technique requires isolation and division of the vas and operative management of the vasal ends. Removal of at least 15 mm of vas is recommended, although division of the vas without removal of a segment is effective when this technique is combined with other techniques for handling the vasal ends, such as thermal luminal fulguration and proximal fascial interposition. Ligation of the ends without the aid of surgical clips may result in necrosis and sloughing of the ends, which may cause early failure. Leaving the testicular end of the vas open has been shown to be effective and to result in a lower incidence of epididymal congestion and sperm granuloma. The no-scalpel technique offers shorter operating time, less pain and swelling, and faster recovery.
Common Questions About Vasectomy - Article
ABSTRACT: Vasectomy offers a safe, effective, and permanent method of male contraception, with an overall failure rate of less than 1% in pooled studies. Men older than 30 years in a stable, committed relationship appear to be the best candidates for vasectomy. The no-scalpel technique reduces operative complications, shortens operative time, and hastens resumption of sexual activity. Use of a jet injector instead of a needle to provide local anesthesia (no-needle vasectomy) may reduce pain. Bleeding and infection are short-term complications of vasectomy; long-term complications include sperm granuloma and postvasectomy pain syndrome. One postvasectomy semen analysis demonstrating azoospermia performed after three months and 20 ejaculations is sufficient to establish sterility. Vasectomy reversal is more likely to be successful if performed less than 15 years after vasectomy and in men whose female partner is younger than 40 years.
