Describe barrier methods such as condoms and diaphragms as methods that prevent sperm reaching an egg.

Barrier methods of contraception, including condoms and diaphragms, are designed to prevent sperm from reaching an egg during sexual intercourse. Condoms are worn on the penis or inside the vagina, creating a physical barrier that stops sperm from entering the uterus. Diaphragms are dome-shaped devices inserted into the vagina before intercourse, covering the cervix to block sperm. Both methods not only help prevent pregnancy but also offer protection against sexually transmitted infections (STIs). Their effectiveness relies on proper use, making education on correct application essential for maximizing their contraceptive benefits.
