I thought that LH surges happen to stimulate progesterone increases to induce menstruation. What you want to know is what your FSH level is.... which gets real high during menopause, the FSH keeps up to stimulate a follicle, and as you are out of follicles, it never goes down. LH goes up too, but I thought the FSH was what was used to determine menopause and is more specific. Maybe I have this wrong, but I'm sure someone else will chip in. Maybe it is your FSH that is 74???
