Document Summary

Introduction- the reproductive system: primary function is not homeostasis; its goal is, to pass on the genes of the individuals and, to maintain the species. Testosterone: testosterone is a steroid hormone produced by leydig cells in the testes, production of testosterone involves a series of reactions beginning with cholesterol and formation of several intermediates, interesting! Progesterone is an intermediate product of testosterone production. The male reproductive system review: the testes develop from the common/indifferent gonads in presence of xy chromosomes, testes produce mullerian inhibiting hormone (mih) to cause the regression of mullerian duct, producing testosterone and causing. The ovaries: produce estrogen and progesterone, produce eggs via oogenesis. At this point, only several hundred thousand primary oocytes and follicles have survived. Estrogen: estrogen is formed from androstenedione, estrogen structure is very identical to cholesterol, progesterone is also a steroid hormone produced from cholesterol.
