Vasectomy

Pokanga ara tātea

A vasectomy is a minor procedure that makes a man sterile (unable to have a baby).

Under a local anaesthetic, the tubes (vas deferens) in your scrotum that connect the testicles to your penis are cut. This means that when you ejaculate (cum), the semen (fluid) you make has no sperm in it.

A vasectomy doesn't change your sexual performance and your male hormones do not change.

Complications from a vasectomy are uncommon. You can get a local infection, bleeding, swelling and pain, which improve with simple treatment.

There is a small chance a vasectomy doesn’t work, which is checked by you doing two sperm tests after the procedure.

While considered a permanent form of contraception, in some cases a vasectomy can be reversed if you decide to have child in the future.

Your general practice team or Sexual Wellbeing Aotearoa Clinic can advise you about having a vasectomy including the cost.
