What is a vasectomy?
Vasectomy is surgery a man may choose to have if he does not want to father any more
children. It is lasting (permanent) male birth control.
During the surgery, 2 tubes called the vas deferens are cut and sealed. The vas
deferens carry sperm from testicles to the urethra. The urethra is the tube inside the
penis. Once they are cut, sperm can’t get into the semen or out of the body. The testes
still make sperm, but the sperm die and are absorbed by the body.
man who has had a vasectomy still makes semen and is able to ejaculate. But the semen
doesn’t contain sperm. The testosterone level and all other male sex traits stays the
same. For most men, the ability to have an erection is unchanged.
procedure to reverse a vasectomy doesn’t always work.
Types of vasectomy
- Conventional vasectomy. Small cuts are made on each side of the scrotum
to reach the vas deferens.
scalpel vasectomy. This method is done through 1 tiny hole in the skin. A
tool is used to gently stretch the skin opening so that the vas deferens can be
reached. Because no cuts are made, there is little bleeding and no stitches. It
heals quickly with little or no scarring.
Why might I need a vasectomy?
Choosing a vasectomy as a form of birth control may be a good choice if:
- You are an adult male.
- You are in a stable relationship and both partners agree to permanent birth control.
- Pregnancy would be a health risk for your partner.
- You or your partner has a genetic disorder that you don’t want to pass on to a child.
Vasectomy may not be the best choice for you if:
- You are
not sure if you want to have children in the future.
- You may have other partners in the future.
- You plan to have children by reversing your vasectomy.
What are the risks of a vasectomy?
Vasectomy is very safe, but all surgeries carry some risks. Some possible risks of
- An inflammatory reaction to sperm that spill during surgery called sperm granuloma which can cause a tender lump under the skin
- Epididymitis or orchitis (painful, swollen, and tender epididymis, or testis) may occur after vasectomy. This most often occurs during the first year after surgery.
- In rare
cases, the vas deferens may grow back together. This could cause an unwanted
- Pain that lasts long after surgery
- Short-term bleeding, swelling, and bruising
man can often start having sex again soon after vasectomy. But another birth control
method should be used. This is because some sperm may stay in the vas deferens for some
time after surgery. Other birth control should be used until the surgeon tests the semen
to be sure there are no sperm left. This is often about 3 months after surgery.
