Yukiko is taking a combination birth control pill. How do they prevent her from becoming pregnant?
What will be an ideal response?
Yukiko's pills contain estrogen and progesterone. Birth control pills prevent pregnancy by interfering with the usual feedback cycle between the ovaries and the pituitary. In her case, the estrogen and progesterone prevent the surge of FSH and LH that would otherwise release an ovum. The estrogen-progesterone combination also thickens the mucus of the cervix, making it harder for a sperm to reach the egg, and prevents an ovum, if released, from implanting in the uterus.
