A vasectomy is a procedure which prevents sperm travelling from the testicles to the penis by blocking, cutting and sealing the Vas Deferens (tubes).
The injection of minute quantities of neem oil into the vas deferens has been successfully tested as an alternative to vasectomy.
Monitoring is important because vasectomies are not 100 percent successful, and men who have had them can experience recanalization, or the spontaneous healing or restoration of the vas deferens, which restores their fertility.
