The term “progesterone” means “for gestation (or pregnancy).” Describe how progesterone helps prepare the female body for pregnancy and helps maintain pregnancy.
Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).
Polycystic ovarian syndrome (PCOS) is an endocrine disorder. PCOS may result in irregular periods, elevated levels of male hormones, and enlarged ovaries with fluid filled sacs called cysts.Doctors may prescribe birth control pills containing only progesterone to help regulate periods and reduce symptoms.Progesterone plays an important role in the ovarian and uterine cycles.
Describe the functions of progesterone during the cycle (at LEAST 2).
