Effectiveness: Nearly 100%

A permanent form of male birth control. A health care provider closes or blocks the spermatic ducts which prevents sperm from leaving the male’s body and cause pregnancy.


Availability: Through health care provider 

Cause of Failures: Rarely, the spermatic ducts grow back together again and allow sperm to flow out of the male again – risking pregnancy.

STI Prevention: None

Note: Not immediate. Sperm remains beyond the blocked tubes. Takes about 3 months. A semen analysis shows when there are no sperm in the ejaculate.
