ICL is a condition with low CD4+ T cells like AIDS but not caused by HIV, and normal CD4+ T cell counts may vary between men and women.
research Hormone Therapy in Acne
Hormonal treatment is effective for women with acne not helped by usual treatments, especially if they have hormonal imbalances.
research Evidence of Increased DNA Methylation of the Androgen Receptor Gene in Occipital Hair Follicles from Men with Androgenetic Alopecia

research A Rare Repigmentation Pattern in a Vitiligo Patient: A Clue to an Epidermal Stem-Cell Reservoir of Melanocytes?
Repigmentation in vitiligo may come from melanocyte stem cells in the skin.
research Hormonal Therapy in Dermatology
Hormonal therapy is a treatment option for acne, the only medical treatment for hirsutism, and the most promising for androgenetic alopecia.
research Consequences of Steroid-5α-Reductase Deficiency and Inhibition in Vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Contraceptive Use in Acne
Hormonal contraceptives can help treat acne by affecting sebum production and androgen levels.
research The Role of Non-Aromatizable Testosterone Metabolite in Metabolic Pathways
Normal levels of DHT can reduce belly fat and increase muscle, but too much can lead to hair loss, prostate issues, and possibly heart disease.
research The Steroidogenesis Inhibitor Finasteride Reduces the Response to Both Stressful and Rewarding Stimuli
Finasteride reduces response to stress and rewards, affecting behavior and mental health.
research Expression of Androgen Receptor Coactivator ARA70/ELE1 in Androgenic Alopecia
The protein ARA70/ELE1 is involved in male pattern baldness, and lower levels of its short form may lead to hair thinning.
research Safety and Tolerability of the Dual 5-Alpha Reductase Inhibitor Dutasteride in the Treatment of Androgenetic Alopecia
Dutasteride is safe and effective for treating hair loss, but may decrease libido.

Some skin medications can harm male fertility, but they don't seem to cause birth defects from father's exposure.
research Male Androgenetic Alopecia
Male pattern baldness involves hormone-related hair thinning, shorter hair, and inflammation.
research 5α-Reductase Inhibitors
Finasteride effectively treats enlarged prostate and male baldness, improves symptoms of hirsutism in women, but doesn't work for acne, and may delay prostate cancer progression with few side effects.
research The Role of the Adrenal Glands in Regulating Onset of Winter Fur Growth in Mink (Mustela Vison)
Adrenal glands delay the start of winter fur growth in mink.
research Fine Structure and Immunocytochemistry of Monotreme Hairs, with Emphasis on the Inner Root Sheath and Trichohyalin-Based Cornification During Hair Evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Steroid 5α-Reductase 2 Deficiency Leads to Reduced Dominance-Related and Impulse-Control Behaviors
Mice lacking steroid 5α-reductase 2 show less aggression and better impulse control.
