research Urinary steroid metabolome shows adrenal, gonadal, and neuroactive steroid dysregulation in adolescents with depression
Depressed teens have different steroid levels in urine, which may help identify and treat them.
research 5α-Reductase and 11β-Hydroxysteroid Dehydrogenase Activity in Prepubertal Hispanic Girls with Premature Adrenarche
Enzyme activities do not cause early pubic hair in these girls.
research Determination of steroid hormones in human hair as a retrospective biomarker with HPLC-MS/MS
A new method accurately measures long-term hormone levels in hair.
research [Analysis of steroids and binding proteins in the blood of women with androgenetic alopecia].
Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.
research Effect of finasteride on adrenal steroidogenesis in men.
Finasteride, when taken daily, lowers dihydrotestosterone levels but doesn't noticeably affect adrenal steroid production, except by blocking the 5 alpha-reductase enzyme.
research AN ATTEMPT TO ASSESS THE MAGNITUDE OF ENDOGENOUS ANDROGEN PRODUCTION IN A CASE OF THE ADRENOGENITAL SYNDROME*
A 17-year-old female with adrenogenital syndrome produces very high levels of androgens, which prevent complete feminization despite high estrogen doses.
research Synthesis and 5α-Reductase Inhibitory Activity of C21 Steroids Having 1,4-diene or 4,6-diene 20-ones and 4-Azasteroid 20-Oximes
Three specific 4-azasteroid-2-oximes showed strong enzyme inhibition, but less than finasteride.
research Testosterone Metabolism in Human Skin Cells in vitro and Its Interaction with Estradiol and Dutasteride
Different skin cells process testosterone differently, and certain drugs can change this process, possibly helping treat acne and hair loss.
research Dihydrotestosterone Stimulates 5a-Reductase Activity in Pubic Skin Fibroblasts*
Dihydrotestosterone increases the activity of an enzyme in pubic skin cells that converts testosterone to dihydrotestosterone.
research The feasibility of quantitative analysis of androgen metabolism by use of single dermal papillae from human hair follicles
Using single dermal papillae is unreliable for analyzing androgen metabolism in hair follicles.
research The effect of the antiandrogen IIα-hydroxyprogesterone on sebum production and cholesterol concentration of sebum
The antiandrogen 11α-hydroxyprogesterone effectively reduces skin oil and cholesterol when applied to the skin.
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 Steroids excreted by human skin. I. C19-steroids in axillary hair.
Human skin releases different steroids, with some coming from sebaceous glands and others from sweat glands.
research Discovery of Natural Steroid 5 Alpha-Reductase Inhibitors
Natural herbal compounds might treat certain medical conditions by reducing DHT levels, but more research is needed to confirm their effectiveness and safety.
research Establishing and Verifying a Robust Liquid Chromatography-Tandem Mass Spectrometry Method to Simultaneously Measure Seven Androgens Present in Plasma Samples
The method accurately measures seven androgens in plasma and shows different hormone levels in females with acne and obesity.
research Diagnosis of hyperandrogenism: Biochemical criteria
The document concludes that accurate measurement of serum androgens is crucial for diagnosing hyperandrogenism.
research Assessment of diagnostic competence of plasmatic androgens on polycystic ovary syndrome based on receiver operator characteristic curves
Free Testosterone Index, bioavailable testosterone, and androstenedione are the most accurate for diagnosing excess male hormones in PCOS.
research New Synthesis of Methyl 3β-Hydroxy-5-androstene-17β-carboxylate
A new method was developed to make a compound used in finasteride and epristeride with a 69% yield.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research Higher Levels of Steroidogenic Acute Regulatory Protein and Type I 3β-Hydroxysteroid Dehydrogenase in the Scalp of Men with Androgenetic Alopecia
Men with baldness have higher levels of specific proteins, suggesting local hormone production may play a role in hair loss.
research Androgenic hormone profile in patients with androgenetic alopecia
People with hair loss have different hormone levels, and these hormones can affect hair growth.
research P-421 ASSOCIATION BETWEEN STRESS-RELATED HORMONE LEVELS IN HAIR AND SUBJECTIVE MENTAL HEALTH IN JAPANESE WORKERS
Higher cortisol levels are linked to poor coping, while higher DHEA levels are linked to job confidence.
research 유전성 안드로겐탈모증 여성환자의 임상양상과 혈중 dehydroepiandrosterone sulfate 및 total testosterone 치
Hormone levels in women with androgenetic alopecia are similar to those without the condition.
research Sebocytes are the Key Regulators of Androgen Homeostasis in Human Skin
Sebocytes play a key role in controlling androgen levels in human skin.
research Alterations in androgen conjugate levels in women and men with alopecia
People with hair loss may have different levels of certain hormones due to changes in hormone processing.
research Anti-SARS-CoV-2 Action of 5α-Reductase Inhibitors May Be Mediated by Dehydroepiandrosterone. Letter.
Certain drugs like Dutasteride and Finasteride might help fight SARS-CoV-2 by increasing levels of a steroid called DHEA, which can protect the heart and increase nitric oxide to counteract the virus.
