Progesterone activation of β1-containing BK channels involves two binding sites

Nature Communications, 2023
Progesterone (≥1 µM) is used in recovery of cerebral ischemia, an effect likely contributed to by cerebrovascular dilation. The targets of this progesterone action are unknown.

Comparison of the efficacy of vaginal micronised progesterone tablet and gel for in vitro fertilisation

Journal of Obstetrics and Gynaecology
Background Luteal phase support (LPS) with progesterone is a generally accepted practice after controlled ovarian stimulation, although the best protocols for LPS have been debated.

Hypothalamic effects of progesterone on regulation of the pulsatile and surge release of luteinising hormone in female rats

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 and Follicle Stimulating Hormone interact and promote goat preantral follicles survival and development in vitro

Pesquisa Veterinária Brasileira, 2012
We investigated the effects of progesterone and follicle stimulating hormone (FSH) on survival and growth of caprine preantral follicles. Pieces of ovarian tissue were cultured for 1 or 7 days in minimum essential medium (MEM) alone or containing ...

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.

Does pretrigger echogenic endometrium in assisted reproductive technology cycles reflect raised serum progesterone level?

Journal of Human Reproductive Sciences, 2018
Background: Serum progesterone is the main hormone of the luteal phase. The hyperechoic pattern of the endometrium in the luteal phase is believed to be induced by raised serum progesterone.

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 Enhances the Invasion of Trophoblast Cells by Activating PI3K/AKT Signaling Pathway to Prevent Preeclampsia

Cell Transplantation, 2023
We aimed to explore whether the effect of progesterone on preeclampsia via the PI3K/AKT signaling pathway. First, we studied the role of progesterone in preeclampsia patients and HTR-8/Svneo cells by adding progesterone.
