Scientific Reports, 2017 Progesterone can block the oestradiol-induced GnRH/LH surge and inhibit LH pulse frequency. Recent studies reported that progesterone prevented premature LH surges during ovarian hyperstimulation in women. As the most potent stimulator of GnRH/LH release,

Progesterone Regulation of the Progesterone Receptor in Rat Gonadotropes* [PDF]
Endocrinology, 2000 For rat pituitary cells, progesterone receptor (PR) protein localizes to gonadotropes and PR messenger RNA is induced by E2 and rapidly but transiently down-regulated by progesterone. Here we quantitatively establish the down-regulatory effect of progesterone on PR protein and evaluate possible mechanisms.

Effects of Levonorgestrel and progesterone on Oviductal physiology in mammals
Reproductive Biology and Endocrinology, 2018 Background Our previous study indicated that emergency contraception, including levonorgestrel and progesterone, could lead to ectopic pregnancy following contraception failure. However, our understanding of the effects of levonorgestrel and progesterone

Progesterone receptors, their isoforms and progesterone regulated transcription [PDF]
Molecular and Cellular Endocrinology, 2012 This review discusses mechanisms by which progesterone receptors (PR) regulate transcription. We examine available data in different species and tissues regarding: (1) regulation of PR levels; and (2) expression profiling of progestin-regulated genes by total PRs, or their PRA and PRB isoforms.
