The formation of the corpus luteum is triggered by which hormonal event?

Explanation:
The formation of the corpus luteum is tied to a surge of luteinizing hormone that follows the midcycle rise in estrogen. This LH surge triggers ovulation and the luteinization of the ruptured follicle’s cells, transforming them into the corpus luteum. LH stimulates the remaining follicular (luteal) cells to become luteal cells that secrete progesterone (and some estrogen) to prepare the uterus for potential implantation. While FSH drives early follicle growth and estrogen rise helps trigger the LH surge, neither FSH nor estrogen rise directly forms the corpus luteum. Progesterone rise happens after the corpus luteum has formed, as its main product.
