They prevent ovulation

Option: 2

They block sperm from reaching the egg

Option: 3

Option: 4

They cause the lining of the uterus to thin

Answers (1)


Oral contraceptive pills, commonly known as birth control pills, contain synthetic hormones (estrogen and progesterone) that regulate the menstrual cycle. By taking these pills daily, they inhibit the release of eggs from the ovaries, preventing ovulation. Without ovulation, there is no egg available for fertilization by sperm, effectively reducing the chances of pregnancy.

Option 1 is the correct answer.
