After vasectomy, a man is unchanged except for his blocked sperm tubes. The testes still produce sperm, but they are simply re-absorbed into the body. Vasectomy does not affect a man's sex drive, masculinity, testosterone levels or orgasm. His ability to have an erection is also fully unchanged. Furthermore, most men report that sex is better after vasectomy because they no longer need to worry about an accidental pregnancy. With the security and peace of mind permanent contraception brings, sex can be more relaxed and spontaneous.
