Answer Most men are often confused, thinking that a vasectomy involves removing the testicles, rendering them unable to perform heavy work normally and causing a decline in sexual performance. Research from the past to the present has found that a vasectomy is a safe method and does not adversely affect the functioning of various systems in the body.
Some men have sexual intercourse a few days after a vasectomy because they want to test whether their organs are still functional. This can result in sperm remaining in the ducts, leading to their wives becoming pregnant even after the vasectomy.
