Progesterone is an essential hormone in the process of reproduction. Although the pharmacokinetics and pharmacodynamics of progesterone have been well studied, its use in the pathophysiology of pregnancy remains controversial. One of these concerns is the way in which the hormone is administered.In obstetrics the most frequent uses of progesterone are ...

Progesterone (P4) is an an intermediate of sex steroids produced by all steroidogenic tissues. It maintains pregnancy and the secretory condition of the uterine endometrium during the luteal phase, and inhibits release of gonadotropins. P4 can bind to progesterone receptor (PR), which is a member of the nuclear receptor superfamily of transcription ...

The role of progesterone (P) in the mechanism of ovulation is controversial at best. The contraceptive application of P was established in rodents in 1936 and with orally absorbed progestogenes was put to human use. There were hints on the proovulatory actions of P administered before the time of ovulation in rats by 1948.

Novel Mechanisms of Progesterone Antagonists and Progesterone Receptor
Journal of the Society for Gynecologic Investigation, 2000The progesterone receptor (PR), as a member of the nuclear receptor superfamily of ligand-dependent transcription factors, activates gene transcription through binding to specific palindromic progesterone response elements (PRE) in the promoter region of progestin-responsive genes.

Progesterone receptor and the mechanism of action of progesterone antagonists
The Journal of Steroid Biochemistry and Molecular Biology, 1995Currently available progesterone antagonists have been suggested to fall into two categories based on differences in how they interact with and inactivate the progesterone receptor (PR). The anti-progestin ZK98299 (Type I) impairs PR association with DNA, while Type II compounds (RU486, ZK112993, ZK98734) promote PR binding to DNA.

Progesterone exerts beneficial effects on the human cardiovascular system by inducing rapid increases in nitric oxide (NO) production in vascular endothelial cells, but the receptors mediating these nongenomic progesterone actions remain unclear.

The hormonal factors associated with converting a corpus luteum of estrous cycle into a corpus luteum of pseudopregnancy were studied by measuring LH and FSH prolactin, estradiol and progesterone levels in decapitated rats during the 4-day estrous cycle ...

Groups of female rats were decapitated at 3-hr intervals throughout 4-day estrous cycles and the plasma of each rat was assayed for LH, FSH, prolactin, progesterone and estradiol-17β.

Abstract: Recent clinical trials in hormone therapy (HT) for women approaching or past menopause have been disappointing. Most women who have been taking conjugated equine estrogens combined with synthetic progestins have been encouraged to stop these supplements because of increased health risks.

SUMMARY The content of progesterone was determined in the peripheral venous blood of cows from the 32nd day of pregnancy until the day before calving. The level ranged from 0·74 to 0·98 μg progesterone/100 ml. plasma throughout the 32nd-256th day period, but thereafter a marked decrease was observed, and on the day before calving the level ...
