So as soon as we have the sharp increase in LH, as soon as he experienced the LH surge, ovulation takes place. So the mature secondary follicle ruptures, releasing this red secondary Oicide into the Peric neal cavity and then into Araphylopian two, while the remaining portion of that becomes into the corpus luteum. So the remaining portion of that secondary falcon that remains inside the Ovary develops into the corpus luteum, also as a result of the increase in LH during our LH surge. So the continued release of LH stimulates the remaining portion of the secondary follicle to become the corpus luteum. So there should be a U here. And that's exactly why the LH is called the luteinizing hormone because it causes the formation of the corpus lutein.
