research 5alpha-reductase 2 inhibition impairs brain defeminization of male rats: Reproductive aspects

26 citations , September 2005 in “Pharmacology Biochemistry and Behavior”

This study found that inhibiting the 5alpha-reductase 2 pathway in male rats affects brain sexual differentiation and leads to reproductive changes, including increased pre-implantation loss despite unchanged copulatory potential.

research Predominant expression of 5 alpha-reductase type 1 in pubic skin from normal subjects and hirsute patients.

11 citations , May 1996 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism”

This study reported that 5 alpha-reductase type 2 is the predominant enzyme in pubic skin fibroblasts across normal men, women, and hirsute patients, suggesting potential treatment options for idiopathic hirsutism.

research Exploring the Inhibitory Potential of Phytosterols β-Sitosterol, Stigmasterol, and Campesterol on 5-Alpha Reductase Activity in the Human Prostate: An In Vitro and In Silico Approach

12 citations , November 2024 in “Plants”

This study found that the phytosterols β-sitosterol, stigmasterol, and campesterol have low-to-negligible inhibitory activity against steroidal 5α-reductase type 2 compared to the synthetic inhibitor dutasteride, with β-sitosterol showing the highest activity among the tested phytosterols.

research The 5 Alpha-Reductase Isozyme Family: A Review of Basic Biology and Their Role in Human Diseases

218 citations , December 2011 in “Advances in Urology”

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

research Docking and Molecular Dynamics Identify Leads against 5 Alpha Reductase 2 for Benign Prostate Hyperplasia Treatment

10 citations , March 2023 in “Journal of Chemistry”

This study identified ten novel compounds that may effectively target steroid 5 alpha-reductase 2 (5αR-2) for potential treatment of benign prostate hyperplasia, exhibiting comparable binding energies to existing drugs like finasteride and dutasteride.

community Minoxidil is a 5ar inhibitor according to research

150 upvotes 11 months ago

Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.

community Having androgen receptor density and sensitivity at wrong f*ing place

in Satire 7 upvotes 1 year ago

The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.

community Creatine is the opposite of minoxidil !

324 upvotes 10 months ago

Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.

community Update: 9 months of oral Dutasteride & topical Minoxidil has done more than I ever expected

831 upvotes 4 months ago

Oral Dutasteride and topical Minoxidil significantly improved hair regrowth over nine months. Other users shared mixed results and side effects with treatments like oral Minoxidil and Finasteride.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

learn Fluridil

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.
