Hey guys, quick question.
I know that FSH and LH are released in the first half (Fol. phase) of the menstrual cycle. Does the stimulate the follicle (which will form) to release estrogen AND progesterone or just estrogen. I ask this because most "menstrual cycle charts and graphs" show little or no progesterone until the luteal phase after ovulation.
Edit: Did a little more research. It seems like the corpus luteum actually secretes progesterone to maintain the lining of the uterus. Looks like its only estrogen in the first part. If anyone wants to correct me, they can
