what two things do contraceptives help prevent
Contraceptives help prevent unwanted pregnancies and the transmission of sexually transmitted infections (STIs).
Contraceptives help prevent two main things:
1. Unintended pregnancies: Contraceptives are used to prevent pregnancy by either stopping ovulation, preventing fertilization of the egg, or inhibiting implantation of a fertilized egg in the uterus.
2. Sexually transmitted infections (STIs): Some forms of contraceptives, such as condoms, provide a physical barrier that helps reduce the risk of transmitting STIs during sexual activity. However, it's important to note that not all forms of contraceptives protect against STIs, so using barrier methods like condoms in combination with other contraceptives is recommended for both pregnancy prevention and STI protection.
