Microscopic Photos of Reproductive System Tissue Slides 3 years, 11 months ago What is your corpus luteum? Your corpus luteum is a completely normal cyst that forms on the ovary every single month in women of childbearing age. This cyst is actually a group of cells inside your ovaries that forms during each menstrual cycle. The corpus luteum is actually a temporary gland structure. It secretes the hormones estrogen and progesterone to prepare the body for the possibility of conception. These hormones help build up the lining of the uterus (to form a nice bed for the egg to implant into) and help maintain that lining.
