Document Summary
~6-7 million oogonia that can develop into oogonia but no more are produced throughout aliveness. Graa an follicle = mature uid lled cavity that sign the ballock.

Right before nascence , some become primary oocytes but most of these will undergo atresia = decadence. What is placenta previa ? obstruction of the cervical canal by the placenta --prevents pattern birth, requires c section on one ovary , there are what are different degree of maturation ? oogonia and oocyte. At birth: two things happen: levels of estrogen reduction = pih output = prolactin output = milk production 2) Neuroendocrine unconditioned re ex = decreased estrogen + baby suckling = decreased pih = stimulate sacking of oxytocin which is necessary for milk let down. What are the four stage of the menstrual cycle: follicular ii . ovulatory 3. luteal quadruplet . menstrual.
