High‐Dose Hormone Replacement Therapy Improved Embryo Transfer Outcomes in a Woman With 21‐Hydroxylase Deficiency Who Had Persistently High Serum Progesterone Levels: A Case Report and Literature Review [PDF]

Clinical Case Reports
Women with 21‐hydroxylase deficiency have reduced fertility because of excessive production of adrenal androgen and progesterone, which can inhibit folliculogenesis, disturb the normal gonadotropin secretion pattern and development of the endometrium ...

Progesterone receptor expression declines in the guinea pig uterus during functional progesterone withdrawal and in response to prostaglandins. [PDF]

PLoS ONE, 2014
Progesterone withdrawal is essential for parturition, but the mechanism of this pivotal hormonal change is unclear in women and other mammals that give birth without a pre-labor drop in maternal progesterone levels.

The effect of weight and body mass index on serum progesterone values and live birth rate in cryopreserved in vitro fertilization cycles

F&S Reports, 2021
Objective: To determine if weight or body mass index (BMI) affects the serum progesterone level at the time of the pregnancy test in cryopreserved blastocyst transfer cycles and to determine if those serum progesterone levels affect live births.

Effect of Individualized Progesterone Supplementation for Luteal Support in Frozen-Thawed Cycles on Pregnancy Outcomes

Gynecology Obstetrics & Reproductive Medicine, 2022
Objective: In frozen-thawed embryo transfer (FET) cycles, preparing a synchronous endometrium for the embryo is essential. Aim of this study is to provide individualized luteal support in hormonally replaced FET cycles, and to evaluate mid-luteal serum ...

Non-genomic mechanisms of progesterone action in the brain

Frontiers in Neuroscience, 2013
Progesterone is a gonadal steroid hormone whose physiological effects extend well beyond the strict confines of reproductive function. In fact, progesterone can have important effects on a variety of tissues, including the bone, the heart and the brain ...

Does serum progesterone level impact the ongoing pregnancy rate in frozen embryo transfer under artificial preparation with vaginal progesterone? Study protocol for a randomized controlled trial

Trials, 2022
Background In previous retrospective studies, low serum progesterone level on the embryo transfer day is associated with lower clinical pregnancy and ongoing pregnancy rates.

A novel therapeutic approach for treatment of catamenial epilepsy

Neurobiology of Disease, 2018
Many women with epilepsy experience perimenstrual seizure exacerbation, referred to as catamenial epilepsy. There is no effective treatment for this condition, proposed to result from withdrawal of neurosteroid-mediated effects of progesterone.
