research Finasteride
Finasteride treats enlarged prostate, improves urinary flow, but may cause sexual side effects.
research A cell-based system for screening hair growth-promoting agents
Apigenin may help promote hair growth and could treat hair loss.
research Finasteride versus cyproterone acetate-estrogen regimens in the treatment of hirsutism
Finasteride and CPA-EE2 equally reduce hirsutism, but affect hormone levels differently.

Testosterone increases cell growth and reduces IL-6 in gum cells.
research Spironolactone Therapy for Hirsutism in a Hyperandrogenic Woman
Spironolactone may help reduce excessive hair growth in women with high male hormone levels.
research 5-Alpha reductase deficiency
5-alpha reductase deficiency leads to male sexual development issues and treatments like finasteride help with prostate enlargement and hair loss.
research ORIGINAL RESEARCH—ENDOCRINOLOGY: Comparison of the Steady‐State Pharmacokinetics, Metabolism, and Variability of a Transdermal Testosterone Patch Versus a Transdermal Testosterone Gel in Hypogonadal Men

research Dutasteride: a review of current data on a novel dual inhibitor of 5alpha reductase.
Dutasteride effectively treats enlarged prostate with manageable side effects.
research Use of Finasteride in the Treatment of Men With Androgenetic Alopecia (Male Pattern Hair Loss)
Finasteride effectively improves hair growth and slows hair loss in men with male pattern baldness.
research Animal models of androgen-dependent disorders of the pilosebaceous apparatus
Testosterone causes hair loss in AGA mice, which are good for testing baldness treatments, and both minoxidil and cyproterone acetate can prevent this hair loss.
research Inhibition of Rat 5α-Reductase Activity and Testosterone-Induced Sebum Synthesis in Hamster Sebocytes by an Extract ofQuercus acutissimaCortex
An extract from Quercus acutissima bark was found to reduce sebum production and block an enzyme linked to acne.
research Age-related hair changes in men: Mechanisms and management of alopecia and graying
Men's hair loss is caused by hormones and genes, and can be treated with medication and surgery, while graying is due to aging and has no prevention except dyeing.
research Membrane androgen receptors may mediate androgen reinforcement
Androgen self-administration might be controlled by membrane receptors, not nuclear ones.
research Efficacy of Topical Combination of 0.25% Finasteride and 3% Minoxidil Versus 3% Minoxidil Solution in Female Pattern Hair Loss: A Randomized, Double-Blind, Controlled Study
Combination of 0.25% finasteride and 3% minoxidil works better than just 3% minoxidil for increasing hair thickness in women.
research Immunohistochemical Evaluation of Androgen Receptor and Nerve Structure Density in Human Prepuce from Patients with Persistent Sexual Side Effects after Finasteride Use for Androgenetic Alopecia
Finasteride, a hair loss drug, may cause long-term sexual side effects due to changes in hormone receptor levels.
research Basics of androgen synthesis and action
Androgens like testosterone are important hormones for both men and women, made differently in each sex and affecting the body by regulating genes and quick interactions with cell components.
research Sex dependent influence of a functional polymorphism in steroid 5‐α‐reductase type 2 (SRD5A2) on post‐traumatic stress symptoms
SRD5A2 gene variations affect PTSD symptoms differently in males and females.
research Intracrine and Myotrophic Roles of 5α-Reductase and Androgens
Muscles can make their own androgens, which may help muscle growth.
research Metformin influence on hormone levels at birth, in PCOS mothers and their newborns
Metformin taken during pregnancy increases SHBG in newborns but doesn't change other hormone levels in mothers or babies.
research Epitestosterone—an endogenous antiandrogen?
Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.
research 7 Regulation of androgen receptor and 5α-reductase in the skin of normal and hirsute women
The exact cause of increased 5α-reductase activity leading to hirsutism in women is still unknown.
research The Effects of Androgens on T Cells: Clues to Female Predominance in Autoimmune Liver Diseases?
Androgens may influence T cells, contributing to higher autoimmune liver disease risk in women.
research Minoxidil increases 17β-hydroxysteroid dehydrogenase and 5α-reductase activity of cultured human dermal papilla cells from balding scalp
Minoxidil boosts enzymes that help hair growth.
research Steroid Chemistry and Hormone Controls during the Hair Follicle Cycle
Differences in enzyme activity and androgen receptors in hair follicles may explain why hair loss appears differently in men and women.
research Hair Biology
