research Synthesis and Pharmacological Evaluation of New Progesterone Esters as 5.ALPHA.-Reductase Inhibitors
Smaller substituents at C-17 enhance the inhibitory activity of progesterone derivatives on 5alpha-reductase.
research Molecular Interactions of New Pregnenedione Derivatives
The new progesterone derivatives effectively inhibit 5α-reductase and bind to the androgen receptor.
research Antiandrogenic progestins for treatment of signs of androgenisation and hormonal contraception
Certain hormone medications can treat symptoms like acne and unwanted hair, regulate periods, and prevent pregnancy in women and teenage girls.
research 17α-Acetoxy-6-bromo-16β-methylpregna-4,6-diene-3,20-dione
A new compound with strong antiandrogenic effects was found, potentially useful for treating conditions like acne and prostate cancer.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
research New Progesterone Esters as 5.ALPHA.-Reductase Inhibitors.
Some new progesterone derivatives are better at blocking testosterone conversion than a common drug.
research Androgenic and anti-androgenic effects of progesterone derivatives with different halogens as substituents at the C-6 position
Different halogens on progesterone derivatives can either block or mimic male hormone effects, depending on their type and amount.
research The effects of synthetic 19-norprogestins on osteoblastic cell function are mediated by their non-phenolic reduced metabolites
Synthetic 19-norprogestins promote bone cell growth and function through their non-phenolic metabolites.
research Progesterone in gender-affirming therapy of trans women
Progesterone may help trans women with breast development and health, but more research is needed.
research Molecular interactions of progesterone derivatives with 5α-reductase types 1 and 2 and androgen receptors
Certain progesterone derivatives can inhibit enzymes and reduce androgenic activity, potentially affecting prostate growth.
research A Review of Androgen‐Progestin Regimens for Male Contraception
Hormonal male contraception is effective and could be market-ready, but more research is needed to ensure safety for all ethnic groups.
research Sex Hormones: Hormonal Contraception and Hormone Replacement Therapy
Hormonal contraceptives and therapies regulate organ functions and treat various conditions.
research Reduced metabolites mediate neuroprotective effects of progesterone in the adult rat hippocampus. The synthetic progestin medroxyprogesterone acetate (Provera) is not neuroprotective
Progesterone protects brain cells, but Provera does not.
research Sequential estrogen-progestin addition to gonadotropin-releasing hormone agonist suppression for the chronic treatment of ovarian hyperandrogenism: a pilot study.
The treatment effectively reduced hair growth and was safe for patients with PCOS, but it needs better bleeding control.
research PR-independent neurosteroid regulation of α2-GABA-A receptors in the hippocampus subfields
Progesterone and its byproducts control a specific receptor in the brain independently of progesterone receptors, affecting conditions related to the menstrual cycle.
research Crystal Structure and Synthesis of 17α-Acetoxy-pregn-4,6-diene-3,20-dione

New pregnane derivatives were more effective than finasteride at inhibiting a key enzyme for male pattern baldness.
research New Aromatic Esters of Progesterone as Antiandrogens
New progesterone-based compounds can block male hormones.
research Sex Hormones and Related Compounds, Including Hormonal Contraceptives
Hormonal contraceptives and related compounds can increase health risks like thrombosis and affect sexual function.
research Progesterone regulates corticosterone elevation and alterations in spatial memory and exploratory behavior induced by stress in Wistar rats
Progesterone helps protect against stress-related memory and behavior issues in rats.
