Contraceptive methods can be behavioral, barrier, or hormonal. Which of these is a barrier method of contraception?

A barrier method of contraception is a type of contraceptive that physically prevents sperm from reaching an egg. Examples of barrier methods include:

1. Condoms: Male and female condoms are barrier methods that prevent sperm from entering the vagina.
2. Diaphragm: A diaphragm is a shallow, dome-shaped cup that is placed over the cervix to block sperm from entering the uterus.
3. Cervical cap: Similar to a diaphragm, the cervical cap is a smaller, thimble-shaped device that covers the cervix to prevent sperm from entering the uterus.
4. Sponge: A contraceptive sponge is a soft, round device that is inserted into the vagina and covers the cervix to prevent sperm from reaching the egg.

Barrier methods are a form of contraception that relies on physical barriers to prevent the union of sperm and egg, providing a protective barrier against pregnancy.
