The corpus luteum (Latin for "yellow body"; plural corpora lutea) is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A. It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation.

Rodents have particular features in CL formation, function, and regression. Menstruation is the cyclic, orderly sloughing of the uterine lining, in response to the interactions of hormones produced by the hypothalamus, pituitary, and ovaries.

The menstrual cycle may be divided into two phases: (1) follicular or proliferative phase, and (2) the luteal or secretory phase. The length of a menstrual cycle is the number of days between the first day of menstrual bleeding Cited by:   Peluffo MC, Stouffer RL, Tesone M.

Maintenance of corpus luteum function throughout pregnancy in corpus-luteum-dependent mammals relies on luteotropic support, which may have complex origins.

In the rat for example, the corpus luteum depends on pituitary luteotropic support in the first half of pregnancy and on support from both trophoblast and decidua in the second.

[Cornelia P Channing; John M Marsh; William A Sadler; National Institute of Child Health and Human Development (U.S.);] -- The purpose of this volume, the proceedings of the Second Ovarian Workshop, is to review the state of the art in, the field of ovarian follicular and corpus luteum function.

Empty tertiary follicle collapses, and under LH stimulation the remaining granulosa cells form the corpus luteum; 2. If fertilization does not occur, progesterone and estrogens levels fall and corpus luteum becomes corpus albicans; end of ovarian cycle; new ovarian cycle begins with activation of another group of primordial follicles.

The first half of pregnancy is primarily a time of preparation for the demands of rapid fetal growth that occur later in pregnancy.

The ovarian cycle refers to the series of changes in the ovary during which the follicle matures, the ovum is shed and the corpus luteum develops (see diagram ).

Numerous undeveloped ovarian follicles are present at birth but they start to mature after sexual maturity. In animals that normally have only one baby at a time only one ovum will mature at once but in litter.

The corpus luteum is a remarkable, transiently functioning organ that provides the endocrine conditions that are necessary and sufficient for the establishment and maintenance of early pregnancy. On a weight basis, it is the most productive steroid-secreting tissue in the body.

It is abruptly formed from the remnants of the preovulatory follicle, and it undergoes continuous change thereafter.

The corpus luteum is a transient endocrine gland in the adult ovary that differentiates from the follicle wall after ovulation.

It is vital to mammalian reproduction as it produces the steroid hormone, progesterone, which acts on the reproductive tract to permit embryo implantation and to support a maternal environment that sustains intrauterine pregnancy.
