1a) State the organ of origin of the following hormones and the function for: GnRH, FSH, LH, Estrogen, and Progesterone.  1b) The menstrual cycle contains both positive and negative feedback loops. Explain how. Please frame your answer using the “monitor -> control centre -> effector” scheme.

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).

Hight levels of progesterone promote:a). Development of the follicle b). Re-growth of the endometrium and mensesc). Thickening, vascularization and glandularization of the endometrium d). Development of the corpus luteume). GnRH pulse frequency to peak

List the hormones that influence the male reproductivesystem and describe their functions.

Progesterone: 1)  Is produced in adult testes and is responsible for genital development, beard growth, muscle development, and sexual drive 2)  Is produced by the placenta during pregnancy, with highest levels seen at conception and then steadily decreasing to non-detectable levels at term 3)  Is lowest is serum during the luteal phase of the menstrual cycle and highest during the follicular phase 4)  Parallels activity of the corpus luteum by rapidly increasing following ovulation and then abruptly falling to initial low concentrations prior to the onset of menstruation no references, just homework.

State the functions of hormones secreted by placenta.

Contrast the effects of FSH and LH.
