Finasteride: persistent erectile dysfunction incidence
Finasteride and Persistent Erectile Dysfunction: Incidence, Risk Factors, and What the Evidence Says Finasteride basics: indications, doses, and mechanism Finasteride is a 5-alpha-reductase inhibitor widely prescribed in urology and dermatology. By blocking the conversion of testosterone to dihydrotestosterone (DHT), it reduces androgenic activity in tissues where DHT plays a dominant role. This mechanism underlies both […]

Finasteride vs Minoxidil: Which Hair-Loss Therapy Should You Start With in 2025?
Mechanisms: Hormone Blocker vs Follicle Energiser Finasteride is a 5-α-reductase inhibitor: one pill a day lowers scalp dihydrotestosterone (DHT) by ≈ 70 %, slowing the miniaturisation that drives androgenetic alopecia. Minoxidil, in contrast, is a vasodilator and mitochondrial booster. Applied as a 5 % foam or taken orally in micro-doses, it improves blood flow and […]
Dutasteride vs Finasteride
Mechanisms: Dual Enzyme Blocker vs Selective Blocker Finasteride inhibits only type II 5-α-reductase, the isoenzyme dominant in scalp follicles; dutasteride blocks both type I and type II, achieving a broader shut-off of DHT synthesis in skin, liver and sebaceous glands. In pharmacodynamic studies a single 0.5 mg dutasteride capsule drives serum-DHT down by 90 %, […]

Hair Loss: A Modern Overview
Why do we lose hair? Scalp hair grows in repeating cycles of anagen (growth) → catagen (regression) → telogen (rest). In androgenetic alopecia (AGA) the anagen phase shortens and follicles miniaturise under the influence of dihydrotestosterone (DHT), produced from testosterone by 5-α-reductase. Genetic studies show that polymorphisms in the androgen-receptor (AR) gene on the X-chromosome, […]
Finasteride for women
Maria was forty-seven when she first saw widening at her part line, a hallmark of female-pattern hair loss that often goes unnoticed until late. Her dermatologist confirmed androgenetic alopecia and explained that, although finasteride is officially approved only for men, mounting evidence supports its off-label use in post-menopausal women. One randomized study from 2023 showed […]
