Birth control

Birth control, also known as contraception, is the practice of preventing pregnancy by using various methods, such as hormonal methods, barrier methods, intrauterine devices (IUDs), and surgical sterilization. Birth control has been used for centuries, and it is one of the most effective ways to prevent unintended pregnancy. Hormonal methods of birth control include the pill, the patch, the ring, and the shot. These methods work by releasing hormones that stop ovulation or make it harder for sperm to reach the egg. The pill is taken once a day, the patch is applied once a week, the ring is inserted into the vagina once a month, and the shot is given once every three months. Barrier methods of birth control include condoms, diaphragms, and cervical caps. These methods work by blocking sperm from entering the uterus. Condoms are the most popular barrier method, and they are the only method that can help protect against sexually transmitted infections (STIs). IUDs are small, T-shaped devices that are inserted into the uterus by a healthcare provider. IUDs work by releasing hormones that prevent pregnancy or by creating an environment in the uterus that is hostile to sperm.
