A cervical cap is a type of barrier contraception that is used to prevent pregnancy. It is a small, soft silicone cup that is placed over the cervix (the opening to the uterus) to block sperm from reaching the egg. The cervical cap works by creating a barrier that physically prevents sperm from entering the uterus.
To use a cervical cap, the cap must be covered with spermicide and then inserted into the vagina before sexual intercourse. The cap is positioned over the cervix and forms a seal to prevent sperm from entering. The cervical cap should be left in place for at least 6 hours after intercourse, but not longer than 48 hours.
It is important to use a new cervical cap with every act of intercourse and to follow the instructions for insertion and removal carefully to ensure that it is used correctly. Regular use of a cervical cap can provide effective protection against pregnancy, but does not protect against STIs.
Common side effects of a cervical cap include:
- Irritation or discomfort
- Allergic reactions to the spermicide
- Increased risk of urinary tract infections
It is important to talk to a healthcare professional about the risks and benefits of a cervical cap, and to discuss any health conditions or medications that may affect its use.
