We took in collage that about 14 follicle undergoes follicule phase each month but only follicle which become large than all and due to its secretion of estrogen it, decrease the secreation of fsh but it increase also the no. Of fsh receptor so the it makes intrinsic postive feedback in this large follicle., so the the rest of small follicles will degenerate and only this large follicle will be able to survive(thug life awii), but if that was really the reason for the the ovaries alterntnation in ovum secreaction., why cant one ovary secrete an ovum in 2 successive months?, this may be due to Corpus albican which remains for months till it degenerates (so it. Basically occupy space allowing the other ovary to produce the next month ovum), I really dont know if I am right or wrong, and I havenot searched alot, so if anyone have the answer please till me 😀😀😀
Dear Sandrew,
could you please tell me for which species you are asking this question?
Kind regards,
Daniela
It is possible that in humans the corpus luteum, via progesterone secretion,
diminishes the local estrogen receptor synthesis. Granulosa cells of the
opposite side have more estrogen receptors and respond better to the FSH
estimulation. I can not remenber the references at this time
The ovaries have two main reproductive functions in the body. They produce oocytes (eggs) for fertilisation and they produce the reproductive hormones, oestrogen and progesterone. The function of the ovaries is controlled by gonadotrophin-releasing hormone released from nerve cells in the hypothalamus which send their messages to the pituitary gland to produce luteinising hormone and follicle stimulating hormone. These are carried in the bloodstream to control the menstrual cycle.
Wish you good luck.
but why they alternate , why the ovary alternate in producing the ova
