Gefitinib can cause scalp skin issues and permanent hair loss.
research Moth-eaten alopecia
"Moth-eaten alopecia" can be a sign of secondary syphilis, treatable with penicillin.
research Moth-eaten alopecia as a sole manifestation of secondary syphilis in an adolescent: Role of a dermatologist
A dermatologist helped identify syphilis in a teenager who only had hair loss.
research High-risk male teenager with concurrent gonorrhea and syphilis infection: An alarming call

research Abstracts from the current global literature: Finasteride and sexual dysfunction
Finasteride, a hair loss drug, can cause sexual side effects like erectile dysfunction in 2.1%-3.8% of users, but these usually go away with time or if the drug is stopped. Despite this, its impact on sexual function is minimal for most men.
research Modelling androgen synthesis and action during human sexual differentiation
Male sexual differentiation is regulated independently, while female differentiation occurs in an androgenic environment, affecting conditions like congenital adrenal hyperplasia.
research The Aromatase Inhibitor Fadrozole and the 5-Reductase Inhibitor Finasteride Affect Gonadal Differentiation and Gene Expression in the Frog Silurana tropicalis
Fadrozole and Finasteride change frog sex ratios and cause intersex animals with altered gene expressions.
research Sex Reversal in Birds
Both genetic and hormonal factors are crucial for bird sex differentiation, and disturbances can cause sex reversal.
research Androgen Levels and Body Size Are Associated with Directional as Well as Fluctuating Asymmetry Patterns in Adult !Kung San and Kavango Males from Northern Namibia
Higher androgen levels are linked to less asymmetry in !Kung San males.
research Microscopic sex-based differentiation of human scalp hair among university students in Nigeria
Male and female scalp hair differ in size, density, length, curliness, pigmentation, and cuticle preservation.
research Comparative study of male and female human hair: A microscopic analysis.
Male and female human hairs have different microscopic structures that can help in forensic analysis.
research Human hair morphology: a scanning electron microscopy study on a male Caucasoid and a computerized classification of regional differences.
Hair varies in size and features depending on body region.
research Fadrozole and finasteride exposures modulate sex steroid- and thyroid hormone-related gene expression in Silurana (Xenopus) tropicalis early larval development
Fadrozole and finasteride change gene expression related to sex hormones and thyroid hormones in frog larvae development.
research 863 Molecular basis of hair follicle donor dominance in androgenetic alopecia and sexual dimorphism of the skin
Hair loss patterns differ between males and females due to 5 master regulators and JAK-STAT signaling affects hair growth.
research Informational dichotomy of the mind; the role of sexual neuromodulators
Human sexuality involves complex mental processes unique to humans.
research Evidence for Genetic Heterogeneity in Monilethrix
research Gender-linked differences in human skin
Male and female skin differ in many ways, which could lead to gender-specific skin treatments.

A rare gene variant causes sexual development issues in siblings, needing personalized treatment.
research Worldwide cohort study of 46, XY differences/disorders of sex development genetic diagnoses: geographic and ethnic differences in variants
About 50% of 46, XY DSD cases lack a genetic diagnosis, but advanced sequencing methods improve detection.
research Disorders of Sex Development
DSDs are birth conditions causing unusual sex development, managed with personalized care and sometimes surgery, but still lack a standard treatment approach.
