Vasectomy - Picture Summary

726 Users are discussing this topic

This leaflet gives a brief summary of vasectomy.

See separate leaflet called Vasectomy for more detailed information.

  • Vasectomy is permanent - it is very difficult to undo.
  • There is a small failure rate - rarely, the cut ends grow back together.
  • Sex is not affected. Almost all semen is made in the seminal vesicle and prostate.
  • The operation is easier than female sterilisation, and more effective.
  • About eight weeks after the operation you will need to produce two semen tests about 3-6 weeks apart. If these are clear of sperm you will be given the all clear.
  • You will need to use other forms of contraception, such as condoms, until you are told you are no longer at risk of making your partner pregnant.
