A vasectomy is a safe, effective, and low-risk surgical procedure used as a form of male birth control. The surgery involves cutting and sealing the vas deferens, the tubes that carry sperm from the testicles.

A vasectomy is typically performed as an outpatient procedure with local anesthesia. While it doesn’t usually present major risks or complications, some discomfort can occur, such as:

  • Pain
  • Bruising
  • Infection
  • Swelling

This birth control method is recommended for those who:

  • Don’t want to use other forms of birth control, such as condoms.
  • Don’t wish to have children.
  • Are in a high-risk pregnancy that could jeopardize the woman’s health.
  • Have a genetic disorder they don’t want to pass on to a child.

If you have testicular pathology or chronic testicular pain, a vasectomy is not for you. Consult with your doctor about other alternatives.

Vasectomy Risks and Complications

Although a vasectomy does not typically cause complications or side effects, in some cases, the following risks may occur after the surgery:

  • Elevated temperature
  • Redness and tenderness of the scrotum
  • Scrotal bruising
  • Hydrocele (swelling of the scrotum)
  • Infection at the surgical site
  • Spermatocele
  • Bleeding under the skin, which can cause painful swelling
  • Post-vasectomy pain syndrome

In rare cases, the vas deferens can grow and reconnect, which may cause sperm to mix with semen, leading to a possible pregnancy. However, postoperative medical care significantly reduces these risks.

The Procedure

A vasectomy is performed under local anesthesia, which means you will be awake and a medication will be given to numb the surgical area. The surgery takes between 15 and 35 minutes.

A vasectomy is considered successful after your doctor examines your semen a week after the surgery to ensure it no longer contains sperm.

It’s important that after the surgery you:

  • Protect the scrotum with a bandage and tight-fitting underwear for at least 48 hours after the vasectomy.
  • Use a scrotal support for 3 to 4 days.
  • Apply cold compresses to the scrotum for the first few days.
  • Avoid exercising and lifting objects, especially during the first week.
  • Avoid having sexual intercourse for at least the first two weeks.
