What happens when the Pituitary Gland secretes LH?

Explanation:
LH surge from the pituitary signals the ovary to release a mature egg and begin forming the corpus luteum. This rapid rise causes the follicle to rupture, releasing the oocyte (ovulation), and the leftover follicular cells transform into luteal cells that make the corpus luteum. The corpus luteum then secretes progesterone (and some estrogen), which supports the uterine lining for possible implantation and provides negative feedback to dampen further FSH and LH. This combination of ovulation plus luteinization is why the correct choice is that LH triggers ovulation and formation of the Corpus Luteum.
