Summary
FSH, LH, oestrogen and progesterone interact in feedback loops to time ovulation and menstruation.
In depth
Oestrogen has negative feedback on FSH and LH during most of the cycle but positive feedback at mid-cycle, causing the LH surge. Progesterone maintains the endometrium and inhibits FSH and LH.
FSH rises in early follicular phase. Oestrogen's positive feedback at high levels triggers the LH surge. Progesterone peaks mid-luteal phase.
Example: contraceptive pills use steady hormones to block the surge.
