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

Life, 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

Rapid progesterone actions on thymulin-secreting epithelial cells cultured from rat thymus [PDF]

, 1999
Many soluble factors of neural, endocrine, paracrine and autocrine origin are present in the thymus and modulate its function. Long-term effects of sex steroids have! been documented for thymocytes and cells of the thymic microenvironment. In this report

Human amniotic fluid glycoproteins expressing sialyl Lewis carbohydrate antigens stimulate progesterone production in human trophoblasts in vitro [PDF]

, 2004
Background: Progesterone is thought to mediate immune modulator effects by regulating uterine responsiveness. The aim of the study was to clarify the effect of transferrin and glycodelin A (former name PP14) as sialyl Lewis X-expressing glycoproteins on ...

Mice lacking progesterone receptor exhibit pleiotropic reproductive abnormalities.

Genes & Development, 1995
Although progesterone has been recognized as essential for the establishment and maintenance of pregnancy, this steroid hormone has been recently implicated to have a functional role in a number of other reproductive events.

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

Journal 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

Complex CatSper-dependent and independent [Ca2⁺]i signalling in human spermatozoa induced by follicular fluid [PDF]

, 2017
STUDY QUESTION: Does progesterone in human follicular fluid (hFF) activate CatSper and do other components of hFF modulate this effect and/or contribute separately to hFF-induced Ca2+ signaling?SUMMARY ANSWER: hFF potently stimulates CatSper and ...
