A.
Corpus luteum
Progesterone is a steroid hormone and main female sex hormone. It is secreted during the later half of the menstrual cycle in human females by temporary endocrine tissue, the corpus luteum. The luteinizing hormone (LH) of anterior pituitary brings about a rupture of the Graafian folllicle to release the ovum and changes the ruptured follicle into a yellow structure called corpus luteum, which secrets progesterone.
