Quick Summary

A cervical cap is a contraceptive device designed to prevent pregnancy. It is typically made of rubber or plastic and shaped like a thimble. The cap fits snugly over the uterine cervix, creating a barrier that blocks sperm from entering the uterus.1

Contraception, or birth control, involves preventing conception. Historically, methods focused on preventing semen from entering the uterus, such as coitus interruptus. Modern contraception includes a range of methods like sterilization, hormonal contraceptives (pills, injections), intrauterine devices (IUDs), and barrier devices such as condoms, diaphragms, and cervical caps, often used with spermicides.2
