Salivary estradiol and progesterone across the menstrual cycle: Association and agreement with serum concentrations [PDF]

Physiological Reports
Saliva provides a noninvasive alternative to serum for serial sampling of estradiol and progesterone. This study examined salivary estradiol and progesterone patterns and the relationship between salivary and serum estradiol, progesterone, and the ...

Vaginal versus Intramuscular Progesterone in the Prevention of Recurrent Preterm Labour [PDF]

Al-Azhar International Medical Journal, 2021
Background: Preterm labHarbor is characterized as the occurrence of uterine contractions of sufficient frequency and intensity to affect the cervix's progressive effacement and dilation before to term gestation.

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 ...

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

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 ...

Quantitative of progesterone using isotope dilution-matrix-assisted laser desorption ionization-time of flight mass spectrometry

MethodsX, 2020
A quantification assay based on isotope dilution mass spectrometry to determine the concentration of progesterone in human serum was reported. Incorporated with 13C3-progesterone, serum samples were subjected to progesterone extraction and clean-up by C4
