research Faculty Opinions recommendation of Investigation of four novel male androgenetic alopecia susceptibility loci: no association with female pattern hair loss.
The research found that certain genes are linked to male pattern baldness, but these same genes do not affect female pattern hair loss.
research Phase-specific differential regulation of mechanical allodynia in a murine model of neuropathic pain by progesterone
Progesterone initially worsens but later reduces neuropathic pain in mice, through different mechanisms.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Effect of norplant on androgens and sexual function
Norplant implants lower some androgen levels but don't significantly change sexual function.
research Correlation Between Nongenomic Action of C19-Steroids and COVID-19 Severity
Low testosterone may increase COVID-19 severity in men.
research Botanical drug preparations for alleviating hair loss in menopausal women: a global ethnopharmacological mini-review
Botanical treatments like saw palmetto, rosemary oil, and ginseng may help reduce hair loss in menopausal women.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
research 9 Pilosebaceous physiology in relation to hirsutism and acne
Male hormones are important for hair and oil gland development and can cause conditions like excessive hair growth and acne.
research Causal effects of genetically determined metabolites on androgenetic alopecia: A two‐sample Mendelian randomization analysis
