Female Sterilization

Female surgical sterilization (also called tubal sterilization, tubal ligation, and tubal occlusion) is a low-risk, highly effective one-time procedure that offers lifelong protection against pregnancy. About 700,000 women undergo this procedure each year in the US, where it is the most popular form of contraception.

Basics of Female Sterilization

Female surgical sterilization procedures block the fallopian tubes and thereby prevents sperm from reaching and fertilizing the eggs. The ovaries continue to function normally, but the eggs they release break up and are harmlessly absorbed by the body. Tubal sterilization is performed in a hospital or outpatient clinic under local or general anesthesia.

The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth.

Sterilization does not cause menopause. Menstruation continues as before, with usually very little difference in length, regularity, flow, or cramping. (One study suggested that women with a history of Cesarean section may experience slightly heavier bleeding.) Sterilization does not offer protection against STDs.
