Corpus luteum

Common card · No. 298140

The corpus luteum (Latin for "yellow body"; pl.: corpora lutea) is a temporary endocrine structure in the ovaries involved in the production of relatively high levels of progesterone, and moderate levels of estradiol, and inhibin A. It is the remains of the ruptured ovarian follicle that has released a mature ovum during ovulation. The corpus luteum is colored as a result of concentrating carotenoids (including lutein) from the diet and secretes a moderate amount of estrogen that inhibits further release of gonadotropin-releasing hormone (GnRH) and thus secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). A new corpus luteum develops with each menstrual cycle.
