Document Summary
Embryonic: testes -> testosterone -> induces primary male reproductive organs. Release hormone from the hypothalamus to the anterior pituitary to androgen production and spermatogenesis. Egg is expelled from follicle into oviduct to uterus. Placenta: fetal and maternal blood vessels meet for oxygen supply and nutrition. Testosterone is an example of a. b. c. d. e. Fsh: follicle stimulating hormone stimulates growth of follicles. Estrogen goes up so there is a peak in lh and fsh week 10 page 1. Estrogen goes up so there is a peak in lh and fsh. If both hormone levels go up, there is negative feedback. Growling follicles secrete estrogen; estrogen stimulates gnrh release in hypothalamus. Lh causes follicular tissue to form corpus luteum. Lh causes corpus luteum to secrete estrogen and prog. Causes development of endometrium; fluid nutrition for embryo. No release of fsh and lh; corpus luteum degenerates. Low estrogen and prog causes fsh increase stimulation new growth of follicles.
