do condoms prevent pregnancy
Condoms are a barrier method of contraception that, when used consistently and correctly, can prevent pregnancy by blocking the passage of semen into the vaginal canal. Condoms can also prevent the exchange of blood, semen, and vaginal secretions, which are the primary routes of STD transmission. In recent years, as a result of misinformation and insufficient research, the efficacy of condoms, especially in terms of STD prevention, has been debated in many forums.
