Vasectomy, a surgical procedure for male sterilization, is designed to prevent pregnancy. However, in rare cases, pregnancy can still occur after a vasectomy. Research shows that for every 1,000 vasectomies performed, 1-2 women may get pregnant.
The benefits of vasectomy include its high effectiveness in preventing pregnancy, its low rate of complications, and its permanence. The historical development of vasectomy can be traced back to the 19th century when it was first performed in England.
