What is a vasectomy?

Vasectomy is a simple operation that makes a man sterile, or unable to father a child. The procedure blocks or cuts the tubes that carry sperm from the testicles. After vasectomy, sperm cannot be mixed with semen, which is the fluid a man ejaculates during orgasm. Semen is not made in the testicles, and vasectomy doesn't affect the semen or how it is ejaculated. It's just that, after vasectomy, a man's semen contains no sperm, so he cannot make a woman pregnant. 

A vasectomy is a simple procedure that prevents the release of sperm into the seminal fluid. When the man ejaculates, the semen contains no sperm, but men still experience the full pleasure of intercourse.

However, it is very difficult and expensive to reverse a vasectomy, and you’ll need to be certain about your decision. Some men opt to store some of their sperm before vasectomy for possible in vitro fertilization or artificial insemination, should they decide they want children at some later time.
