December 2004 in “Neuropharmacology” Progesterone reduces anxiety without needing progesterone receptors.
48 citations
,
February 1999 in “PubMed” This study found that the anticonvulsant effects of progesterone against PTZ-induced seizures in mice require conversion to allopregnanolone, as shown by the reversal of these effects with a 5alpha-reductase inhibitor.
September 2023 in “Biology of reproduction” This study suggests that the testosterone analogs 7α-Methyltestosterone and 7α-Ethyltestosterone may offer promising androgenic, progestogenic, and anabolic properties for development as male contraceptives.
19 citations
,
June 1999 in “Steroids” This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.
19 citations
,
June 2006 in “Physiology & Behavior” Finasteride slows down motherly behavior in first-time pregnant rats.
December 1998 in “Acta Crystallographica Section C-crystal Structure Communications” This study describes the molecular conformation and intermolecular interactions in the crystalline structure of the compound C24H31BrO4.
14 citations
,
March 2017 in “Brain research” This study suggests that ovarian cycle-related progesterone and neurosteroids regulate α2-subunit expression of GABA-A receptors in the hippocampus through a pathway independent of progesterone receptors, potentially affecting brain conditions linked to the menstrual cycle.
41 citations
,
November 2003 in “Annals of the New York Academy of Sciences” This article discusses the complexities of androgen and antiandrogen therapies in women, detailing diagnostic measures, the effects on libido, and the potential benefits of new progestins with antiandrogenic properties, but presents no new empirical findings.
9 citations
,
May 2011 in “Hormones and Behavior” Allopregnanolone, a progesterone metabolite, helps reduce restraint effects on behavior.
18 citations
,
January 2002 in “Chemical & pharmaceutical bulletin/Chemical and pharmaceutical bulletin” This study found that several new pregnane derivatives, especially steroids 16 and 19, demonstrated higher antiandrogenic activity on male hamster models than the commonly used finasteride.
January 2006 in “Benzina: Revista d'excepcions culturals” This study observed that new trienone compounds consistently showed higher 5alpha-reductase inhibitory activity compared to corresponding dienones across various biological models.
2 citations
,
January 1985 in “Theriogenology” Hormonal treatments affect cow fertility and early embryo development.
December 2023 in “Frontiers in pharmacology” In this study, intrathecal progesterone administration initially worsened mechanical allodynia in mice after nerve injury, but later reduced pain when applied during the maintenance phase, highlighting distinct roles for cytochrome P450c17 and 5α-reductase in neuropathic pain modulation.
25 citations
,
January 2017 in “Steroids” This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.
9 citations
,
April 2018 in “Biology of reproduction” This study concluded that dietary changes alter serum progesterone and estradiol levels in late gestation ewes, likely due to metabolism rather than changes in placental steroid synthesis.
83 citations
,
July 2004 in “Pharmacology Biochemistry and Behavior” Higher 3α,5α-THP levels in the brain may reduce depression in pregnant rats.
August 2022 in “Theriogenology” This study found that allopregnanolone has a bimodal effect on prolactin secretion in sheep, stimulating PRL mRNA expression but inhibiting hormone release under stress and pregnancy conditions.
7 citations
,
January 2018 in “Reproduction” This study found that dutasteride treatment in pregnant mares significantly increased progesterone concentrations but did not alter gestational length or neonatal outcomes.
17 citations
,
November 2017 in “Experimental physiology” This study found that in newborn rats, progesterone's effects on apnoea frequency are influenced by a sex-specific balance between its metabolite allopregnanolone and progesterone receptors.
103 citations
,
April 2005 in “Experimental dermatology” This study found that PGF2alpha analogues and PGE2 stimulated hair follicle activity in mice, with PGF2alpha analogues also linked to potential side effects like poliosis when used as eye treatments.
