Progesterone and neuroprotection [PDF]

open access: yesHormones and Behavior, 2013
Numerous studies aimed at identifying the role of estrogen on the brain have used the ovariectomized rodent as the experimental model. And while estrogen intervention in these animals has, at least partially, restored cholinergic, neurotrophin and cognitive deficits seen in the ovariectomized animal, it is worth considering that the removal of the ...

Progesterone and Estrogen Signaling in the Endometrium: What Goes Wrong in Endometriosis?

open access: yesInternational Journal of Molecular Sciences, 2019
In the healthy endometrium, progesterone and estrogen signaling coordinate in a tightly regulated, dynamic interplay to drive a normal menstrual cycle and promote an embryo-receptive state to allow implantation during the window of receptivity.

Transdermal Delivery of Bioidentical Progesterone with a Steroid 5α-Reductase Inhibitor (Dutasteride): a Pilot Study

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2011
Purpose: Bioavailability of transdermal progesterone is low and variable. This may be attributed to transdermal metabolism by the 5α-reductase enzymes or the direct transport to the saliva. The objective of the current study was to evaluate the effect of

Steroid hormone bioavailability is controlled by the lymphatic system

open access: yesScientific Reports, 2021
The steroid hormone progesterone accounts for immune tolerance in pregnancy. Enhanced progesterone metabolism to 6α-OH-pregnanolone occurs in complicated pregnancies such as in preeclampsia with preterm delivery or intrauterine growth restriction, and in

Progesterone and neurology

open access: yesGynecological Endocrinology, 1999
Neurological diseases are frequently observed in perimenopausal women and can be characterized by their gender-specific occurrence. These observations raise the question whether sex steroids are also involved in neurological diseases. Epidemiological data have shown that in Austria in 1993, the prescription rate of psychotropics, hypnotics, and ...

Androgens Tend to Be Higher, but What about Altered Progesterone Metabolites in Boys and Girls with Autism?

open access: yesLife, 2022
Background: Evidence exists that steroid hormones are altered in individuals with autism, especially androgens. Despite lower prevalence in girls than boys, evidence of potential alterations in progesterone metabolites is sparse, so the aim of this study
