How it works
Condoms are the only reversible non-hormonal birth control method available for men. They are sheaths worn over the penis during sex that block semen from entering the vagina and reduce skin-to-skin contact, which lowers the risk of sexually transmitted infections.
How well it works
With perfect use, condoms are 98% effective at preventing pregnancy. Typical use is about 87% because of breakage, slippage, or inconsistent use. Latex is the most common material, but polyisoprene and polyurethane options work for people with latex allergies. Lambskin condoms prevent pregnancy but do not block viruses like HIV.
Where to get it
You can buy condoms over the counter at pharmacies, retail stores, or online. Many health clinics give them away free. Until new male contraceptive methods complete clinical trials, condoms remain the only reversible non-hormonal option for men.
