Questions: How does emergency contraception reduce the risk of pregnancy? A. It stops the release of eggs from the ovaries. B. It improves the movement of sperm. C. It destroys the fertilized egg.

The answer is A: It stops the release of eggs from the ovaries.

Explanation for each option:

A. It stops the release of eggs from the ovaries.

• This is correct. Emergency contraception primarily works by preventing or delaying ovulation, which is the release of an egg from the ovary. If there is no egg available for fertilization, pregnancy cannot occur.

B. It improves the movement of sperm.

• This is incorrect. Emergency contraception does not enhance sperm movement. In fact, it aims to prevent fertilization by inhibiting ovulation or altering the uterine lining.

C. It destroys the fertilized egg.

• This is incorrect. Emergency contraception does not destroy a fertilized egg. Its primary mechanism is to prevent fertilization or implantation by delaying ovulation or altering the uterine environment.

In summary, emergency contraception reduces the risk of pregnancy mainly by stopping the release of eggs from the ovaries.
