The yellow body derived from the ruptured OVARIAN FOLLICLE after OVULATION. The process of corpus luteum formation, LUTEINIZATION, is regulated by LUTEINIZING HORMONE.
Degradation of CORPUS LUTEUM. In the absence of pregnancy and diminishing trophic hormones, the corpus luteum undergoes luteolysis which is characterized by the involution and cessation of its endocrine function.
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Process of maintaining the functions of CORPORA LUTEA, specifically PROGESTERONE production which is regulated primarily by pituitary LUTEINIZING HORMONE in cycling females, and by PLACENTAL HORMONES in pregnant females. The ability to maintain luteal functions is important in PREGNANCY MAINTENANCE.
PROGESTERONE-producing cells in the CORPUS LUTEUM. The large luteal cells derive from the GRANULOSA CELLS. The small luteal cells derive from the THECA CELLS.
The period in the MENSTRUAL CYCLE that follows OVULATION, characterized by the development of CORPUS LUTEUM, increase in PROGESTERONE production by the OVARY and secretion by the glandular epithelium of the ENDOMETRIUM. The luteal phase begins with ovulation and ends with the onset of MENSTRUATION.

The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

Superoxide dismutase activity, lipid peroxide production and corpus luteum steroidogenesis during natural luteolysis and regression induced by oestradiol deprivation of the ovary in pseudopregnant rabbits. (1/4)

The relationship of oxygen free radicals to corpus luteum function in rabbits was explored during various stages of pseudopregnancy, including natural and induced luteal regression. Induced luteolysis was achieved during mid-pseudopregnancy by removal of an oestradiol capsule placed at the onset of pseudopregnancy, which suppressed ovarian oestradiol production. Activity of manganese superoxide dismutase (Mn SOD) was significantly and positively correlated with ovarian progesterone production (P < 0.01) throughout pseudopregnancy and during natural regression. Oestradiol deprivation for 12, 24 or 72 h resulted in declines in Mn SOD activity and progesterone secretion, although Mn SOD rose and corpus luteum steroidogenesis was restored to normal when the capsule was replaced for 48 h before assessment, having been removed for 24 h. Lipid peroxide and progesterone concentrations were not correlated, although a significant rise in lipid peroxides in the luteal tissue was detected after deprivation of oestradiol for 72 h. Changes in progesterone production and Mn SOD activity were not associated with alterations in concentration of prostaglandin F metabolite. These data suggest that Mn SOD may be involved in regulating function of the corpus luteum during pseudopregnancy in rabbits and that oxygen free radicals may play a role in regression of corpus luteum in this species.  (+info)

The interaction of testosterone and gonadotropins in stimulating estradiol and progesterone secretion by cultures of corpus luteum cells isolated from pigs in early and midluteal phase. (2/4)

The first objective of this research was to define the capacity of corpora lutea of pig to secrete estradiol in the presence of an androgen substrate which was testosterone. The second objective was to define the synergism between gonadotropic hormones such as LH, FSH, and PRL and testosterone as measured by estradiol and progesterone secretion by two types of porcine luteal cells. Luteal cells were collected from newly forming corpora lutea (0-3 days after ovulation) and from mature corpora lutea (8-10 days after ovulation). After dispersion, luteal cells were suspended in medium M199 supplemented with 10% of calf serum and grown as monolayers at 37 degrees C. Control cultures were grown in medium alone while other cultures were supplemented with either testosterone alone at a concentration of 1 x 10(-7) M or with 10, 100, 500 ng LH plus testosterone, 10, 100, 500 ng FSH plus testosterone or 10, 100, 500 ng PRL plus testosterone. After 2 days of cultivation all cultures were terminated and media were frozen at 20 degrees C for further steroid analysis. Testosterone added to the culture medium in the absence of gonadotropins was without effect on estradiol and progesterone secretion by luteal cells collected in the corpora lutea of the early luteal phase. On the other hand testosterone added to the medium significantly increased progesterone and estradiol secretion by cultured luteal cells collected in the midluteal phase of the cycle. No additive stimulatory action of gonadotropins and testosterone on progesterone secretion was observed in cultures of luteal cells from the early luteal phase but this was not the case in cultures of luteal cells from the midluteal phase.(ABSTRACT TRUNCATED AT 250 WORDS)  (+info)

It facilitates implantation by inhibiting uterine motility and stimulates the development of the mammary glands. Low levels of progesterone in pregnancy are associated with fetal growth restriction. Progesterone supplementation in pregnancy seems to improve this. Progesterone is used to treat patients with menstrual disorders (secondary amenorrhea, abnormal uterine bleeding, luteal phase deficiency) and to manage renal or endometrial carcinoma. In combination with estrogen, it is used for contraception and postmenopausal hormone replacement therapy. SYN: corpus luteum hormone; luteal hormone; progestational hormone; progestin (1). ...

Answer (1 of 1): A corpus luteum cyst is considered to be a functional, or simple, ovarian cyst. A corpus luteum cyst may develop after an egg has been released from the follicle. Ideally after the release of an egg, the follicle will become what is called the corpus luteum. If fertilization occurs and a pregnancy results, the corpus luteum will work in providing the young embryo with progesterone until the placenta can take over later in the first trimester. However, if pregnancy does not result the corpus luteum should shrink and dissolve. In some cases the corpus luteum will continue to grow and may fill with fluid or blood. It will then be considered to be a corpus luteum cyst. A corpus luteum cyst, although usually rather small, can continue to grow, sometimes causing much pain and discomfort. If the cyst does not dissolve on its own, which is often the case, a simple laparoscopic surgery, to remove the cyst, may be suggested.
A Corpus luteum cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst rarely occurs at age 50+, because eggs are no longer being released in menopausal women. Corpus luteum cysts may contain blood and other fluids. The physical shape of a corpus luteum cyst may appear as an enlargement of the ovary itself, rather than a distinct mass -like growth on the surface of the ovary. This type of functional cyst occurs after an egg has been released from a follicle. The follicle then becomes a secretory gland that is known as the corpus luteum. The ruptured follicle begins producing large quantities of estrogen and progesterone in preparation for conception. If a pregnancy doesnt occur, the corpus luteum usually breaks down and disappears. It may, however, fill with fluid or blood, causing the corpus luteum to expand into a cyst, and stay in the ovary. Usually, this cyst is on only one side, and does not ...
Thus, it turns out that the corpus luteum in the ovary is formed in the body of a woman every month, and every month resolved.Its perfectly normal to experience and because of this is meaningless.However, there is a likelihood that in case of pregnancy, the corpus luteum does not resolve, and continue to produce progesterone, or after pregnancy the corpus luteum will continue to grow.In this case we speak of the corpus luteum cyst.. cystic corpus luteum usually has a larger than usual size.In this case, the symptoms are the same as during pregnancy: delayed menstruation, nagging feeling in the stomach, its all a result of the work of the hormone.However, pregnancy test gives a negative result.However, most of this state and is not at risk, even during pregnancy.. However, a cyst could still be a problem, if it is too large.In this case, the cyst may burst as a result of mechanical action.For example, if a large impact or physical exertion.And it is internal bleeding, ie the state, threatening ...
Corpus luteum cysts could be agonizing and might set off alterations in menstrual bleeding. Generally this type of cyst will dissolve on its own personalized inside of of various months of forming. At other situations, nonetheless, these are in a position to expand becoming rather substantial and heavy. The fat in the cyst may well trigger the ovary to increase for being twisted. A twisted ovary is incredibly agonizing and may phone for well-being-related consideration. And it actually is this ache that typically leads females to look for out the support of their health care medical doctor ...
