Usage And Synthesis

Progestin contraceptives work by producing pregnant-like conditions in a female to preventovulation.During pregnancy, progesterone is released by the placenta during development ofthe fetus.This in turn suppresses development of egg follicles and ovulation. Progestins mimicthis condition and thus prevent or delay ovulation.Oral contraceptives currently use progestinand estrogen in combination to prevent ovulation and thicken cervical mucus.The latter makeit harder for sperm to enter the uterus and for an egg to implant on the uterine wall.
