Role of LH in the menstrual cycle

LH is a pituitary hormone that remains low throughout most of the menstrual cycle. Around day 14, mid-cycle, there is an exponential rise in LH due to the high estrogen level. This LH spike is what triggers ovulation.

In addition, LH is also responsible for the mature follicle turning into a corpus luteum after expelling the egg it contained.
