1. What does the level of FSH decrease and remain at a relatively low level during days 15-28 of the cycle?
2. What signals the end of one cycle and the beginning of another? <Does it relate to feedback? I really have no idea about these two questions. > Hope you can give me some hints, so i can think it in a right way. Thanks.

please refer to this URL

from the pic., we know that what control (make our body to stop producing FSH) is the occurence of LH.

this is the hint
hypotalamus, GnRH (FSH-RF and LH-RF), and homeostasis.

if you feel hard to find some on net, maybe this will help (^_^), i hope.
