Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen. FI с

Answer 1

1. The role of estrogen in birth control pill is to:

Prevent a rise in FSH and LH thereby preventing follicle maturation. It stimulates the Anterior Pituitary gland and decreases the release of FSH and LH.

2. At day 21 of the 28 day cycle, administration of estrogen and progestin is stopped for 7 days, Low levels of progesterone result in:

Menstruation after a week from 21st day in 28 day cycle as progesterone helps in maintaining and building up endometrium
