![]() If that's not more rather than less confusing? - Someone else 06:22 (UTC) Not confusing at all, thanks. So each month, it depends on whether the left or right ovary is the lucky one to develop a follicle first, shutting the other off. Essentially, the level of FSH increases, stimulates the production of a follicle, the follicle secretes inhibin, which shuts off the FSH, preventing more follicles from developing. It's all ovarian tissue, and it all is responsive to FSH, it just happens to be divided into two (sort of like say the adrenal glands: they don't "coordinate" the amount of cortisol they each produce, they just respond equally to the same stimuli). "For this month, let's make the following deal: If she eats chocolate on the third day of the cycle, it's your turn, pal." AxelBoldt 04:25 (UTC) There's no left/right coordination involved. How do the two ovaries coordinate this? After all, they are exposed to pretty much the same hormones. Left or right ovary is as far as anyone knows, random. It's one egg per menstrual cycle (normally - I'm excluding the use of fertility drugs, abnormal FSH levels, etc.). ![]() Randomness would be too complex to implement -) - FvdP Tarquin 22:29 (UTC) Alternatively one ovary and then the other, I would say. If there were two eggs, you'd get nonidentical twins. Are there typically two eggs produced in each cycle, one from each ovary, or just one? AxelBoldt 21:15 (UTC)ĪFAIK, it's just one, and which ovary produces one is random.
