Definition: Vasectomies, also known as vasectomy or vasectomia, is a surgical procedure that involves removing the fallopian tubes from the ovaries. This technique can be used to prevent pregnancy by preventing sperm from reaching the egg and implanting inside the womb. It was first performed in 1967 during a study of pregnant women who had failed to conceive. The surgery is now commonly performed as part of birth control methods, including hormonal contraceptives and barrier contraception
