The vasectomy is an extremely safe and effective procedure, with vasectomy success rates over 99%.
During the vasectomy procedure, the vas deferentia are sealed preventing sperm from mixing with the semen that is released during ejaculation. A vasectomy is considered a success when there is zero sperm in the ejaculate.
Immediately after a vasectomy the male will not be sterile. Within the next several months the male’s semen will be tested to ensure that the vasectomy was effective, by looking for traces of sperm . It usually takes several months before a couple can have sex without any form of birth control.
Couples should use another form of birth control until the semen has been tested and zero sperm count is confirmed.
At the San Diego Vasectomy Center, a semen analysis will be performed after 4 weeks to test for active sperm at no additional cost. This will help to ensure that the vasectomy was effective and successful. Please note that many vasectomy clinics charge additional fees for post-vasectomy semen analysis.
