Cervical cap

Cervical Cap

The cervical cap is a form of barrier contraception that is used to prevent pregnancy. It is a small, cup-shaped device that is made of silicone and is inserted into the vagina to cover the cervix, thereby preventing sperm from entering the uterus.

History

The cervical cap has been used as a method of contraception for several centuries, with early versions being made from materials such as oiled paper, lemon rinds, and glass. The modern silicone version was developed in the 20th century.

Usage

To use a cervical cap, it must first be filled with spermicide and then inserted into the vagina so that it covers the cervix. It can be left in place for up to 48 hours, and additional spermicide should be applied each time sexual intercourse occurs. After use, the cap should be washed and stored in a cool, dry place.

Effectiveness

The effectiveness of the cervical cap varies depending on a number of factors, including correct usage and whether or not spermicide is used. When used correctly and consistently, it is estimated to be 86% effective for women who have not given birth, and 71% effective for women who have given birth.

Advantages and Disadvantages

Advantages of the cervical cap include the fact that it can be inserted up to six hours before intercourse, it does not affect a woman's natural hormone levels, and it can be used during menstruation. Disadvantages include the possibility of discomfort or allergic reaction to the silicone or spermicide, and a higher risk of urinary tract infections.
