Permanent Contraception
Vasectomy
For this procedure, the vasa deferentia are cut, and the cut ends are ligated or fulgurated. Vasectomy can be done in about 20 minutes; a local anesthetic is used. Sterility requires about 20 ejaculations after the operation and should be documented by 2 sperm-free ejaculates, usually obtained 3 months after the operation. A back-up contraceptive method should be used until that time. Mild discomfort for 2 to 3 days after the procedure is common. Taking nonsteroidal anti-inflammatory drugs (NSAIDs) and not attempting ejaculation are recommended during this period. Complications of vasectomyinclude Hematoma (≤ 5%) Sperm granulomas (inflammatory responses to sperm leakage) Spontaneous reanastomosis, which usually occurs shortly after the procedure The cumulative pregnancy rate is 1.1% at 5 years after vasectomy.
