Desogestrel is a progestogen. Like other progestogen-only pills, desogestrel is best suited for use during breast feeding and for women who may not or do not want to use oestrogens. In contrast to traditional progestogen-only pills, the contraceptive effect of desogestrel is achieved primarily by inhibition of ovulation. Other effects include increased viscosity of the cervical mucus.

Ethinylestradiol is chemically and biologically identical to endogenous human oestradiol. It substitutes for the loss of estrogen production in menopausal women, and alleviates menopausal symptoms. Estrogens prevent bone loss following menopause or ovariectomy.
