How does a vasectomy affect a man’s fertility?


Vasectomy is a simple operation that makes a man sterile, or unable to father a child. The procedure blocks the tubes that carry sperm from the testicles. After the procedure, 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 impregnate a woman. 

Is a Vasectomy an Effective Method of Birth Control?

According to a study done by the Royal College of Obstetricians and Gynaecologists, only one out of every 2000 vasectomies is unsuccessful. This is significantly better than the rate for female surgical sterilisation, which is called tubal ligation. About one out of every 200 to 300 tubal ligations are unsuccessful. 

The National Institutes of Health has also studied vasectomy. In the first year after the procedure, the study determined that only 15 to 20 out of 10,000 couples will experience a pregnancy. As a comparison, approximately 1,400 couples using a condom and 500 couples using oral contraceptives will experience a pregnancy each year. So, the conception rate after the procedure is very low. The main reason that a man could impregnate a woman after he has undergone the procedure is having unprotected sex too soon after the vasectomy procedure has taken place. 

What are the advantages of vasectomy?

It is a one time, relatively inexpensive procedure that is often covered by insurance or state grant programs.

  • It is less expensive and poses less of a medical risk than female sterilisation
  • It is more dependable than any other form of birth control
  • Vasectomy reversal is easier than female sterilisation
  • Eliminates risks to a female partner or oral contraceptives or IUDs
  • Freedom from hassle and worry of contraception
