Oral contraceptive pills do not
Solution:
Oral contraceptive pills are hormonal methods of birth control. They primarily work by inhibiting ovulation, altering the quality of cervical mucus to prevent sperm entry, and making the uterus unsuitable for implantation. These pills contain either progesterone-estrogen combinations or progesterone alone. They do not prevent the physical deposition of semen in the vagina; this is a function of barrier methods like condoms.
