research Physiopathological role of the enzymatic complex 5α-reductase and 3α/β-hydroxysteroid oxidoreductase in the generation of progesterone and testosterone neuroactive metabolites
The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.
research Phase-specific differential regulation of mechanical allodynia in a murine model of neuropathic pain by progesterone
Progesterone initially worsens but later reduces neuropathic pain in mice, through different mechanisms.
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.
research 17α‐estradiol induces aromatase activity in intact human anagen hair follicles ex vivo
17α-estradiol boosts aromatase activity in female hair follicles, potentially helping with hair loss.
research 5α-Reductase Inhibition Prevents the Luteal Phase Increase in Plasma Allopregnanolone Levels and Mitigates Symptoms in Women with Premenstrual Dysphoric Disorder
High-dose dutasteride reduces PMDD symptoms by stabilizing neurosteroid levels.
research Respiratory regulation by steroids in newborn rats: a sex‐specific balance between allopregnanolone and progesterone receptors
Breathing in newborn rats is affected differently by hormones based on their sex.

research Pharmacological Profile of 9,11-Dehydrocortexolone 17α-Butyrate (CB-03-04), a New Androgen Antagonist with Antigonadotropic Activity
CB-03-04 shows promise as a treatment for prostate issues due to its strong anti-androgen effects.
research Iperandrogenismo della donna in menopausa
A 77-year-old woman with hair loss had high testosterone and 17OH-progesterone levels, but no significant findings on imaging.
research A Prospective Study of the Prevalence of Nonclassical Congenital Adrenal Hyperplasia among Women Presenting with Hyperandrogenic Symptoms and Signs
About 2.2% of women with symptoms of high male hormones have a mild form of congenital adrenal hyperplasia, and measuring a specific hormone level can accurately diagnose it.
research Changes in Progesterone Metabolites in the Hippocampus Can Modulate Open Field and Forced Swim Test Behavior of Proestrous Rats
Lowering 3α,5α-THP in the hippocampus increases anxiety and depression in proestrous rats.
research Highly efficient nucleophilic addition of alkyl Grignard reagents to 17-ketosteroids in the presence of cerium(III) chloride: Synthesis of 17α-propyl-17β-hydroxy-4-androsten-3-one, an androgen receptor antagonist
Adding cerium(III) chloride to Grignard reagents improves the making of compounds that could treat prostate issues and hair loss.
research Is 3α, 17β-androstanediol-glucuronide a diagnostic marker in women with androgenic manifestations?
3α, 17β-androstanediol-glucuronide is not a useful marker for androgen excess but may help monitor certain treatments.
research 17-Hydroxyprogesterone Responses to Gonadotropin-Releasing Hormone Disclose Distinct Phenotypes of Functional Ovarian Hyperandrogenism and Polycystic Ovary Syndrome
The research found that polycystic ovary syndrome (PCOS) has two distinct types, with one having more severe hormone and insulin issues.
research Androstanediolglucuronide: A parameter for peripheral androgen activity before and during therapy with cyproterone acetate
3α-AdiolG is a good marker for androgen activity in women with excessive hair growth and decreases with anti-androgen treatment.
research Unusual presentation with polymenorrhagia and markedly high 17-hydroxy progesterone levels in a lady with Non-Classic Congenital Adrenal Hyperplasia.
A woman with non-classic CAH had unusual heavy periods and high hormone levels, improved with treatment.
research Ovine placental steroid synthesis and metabolism in late gestation†
