Testosterone with dutasteride improves muscle strength and body composition in trans men.
research Research on the balance of thiol-disulfide in blood serum in women with telogen effluvium
The balance of thiol-disulfide in women with hair loss is affected but not damaged.
research Glutathione-S-epoxide transferase in human hair follicles
GSH-T levels in hair follicles are similar in smokers and non-smokers and don't increase with certain treatments.
research Age-induced hair greying - the multiple effects of oxidative stress
Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.
research Protective Effect of Retinoic acid preconditioning on H2O2-induced Apoptosis in Hair Cell-like Cells

research Effect of testosterone and its antagonists on knee range of motion through RXFP1 and RXFP2 regulation in rat model (911.12)
Testosterone reduces knee movement, while flutamide and finasteride increase it.
research Testosterone Reduces Tight Junction Complexity and Down-regulates Expression of Claudin-4 and Occludin in the Endometrium in Ovariectomized, Sex-steroid Replacement Rats
Testosterone makes the connections in the uterus lining simpler and lowers certain protein levels, which might lead to infertility.
research Genetic predictors of testosterone and their associations with cardiovascular disease and risk factors: A Mendelian randomization investigation
Testosterone is linked to cardiovascular risk factors and stroke, but its exact role is unclear.
research Alterations of plasma antioxidants and mitochondrial DNA mutation in hair follicles of smokers
Smoking reduces antioxidants and causes DNA damage in hair follicles.
research Metabolic dysfunction in female mice with disruption of 5α-reductase 1
Female mice with disrupted 5α-reductase 1 had significant metabolic issues, including stress response problems, insulin resistance, liver fat buildup, and obesity.
research Sexual steroid regulation of spermatogenesis: new actors enter the stage
Estrogens and androgens are crucial for male fertility.
research Total testosterone to dihydrotestosterone ratio assessed by LC-MS/MS predicts a worse metabolic profile not only in PCOS patients
A higher testosterone to dihydrotestosterone ratio may indicate worse metabolic health in women.
research Re: Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men with Suppressed Testosterone Production: A Randomized Controlled Trial
Testosterone increases muscle mass regardless of DHT conversion blocking.
research Sub-chronic testosterone treatment increases the levels of epithelial sodium channel (ENaC)-α,βandγin the kidney of orchidectomized adult male Sprague–Dawley rats
Testosterone increases certain kidney protein levels, potentially raising blood pressure.
research Sex hormones and sarcopenia in older persons
Sex hormone treatments can increase muscle mass in older adults but have inconsistent effects on muscle function and may carry cardiovascular risks.
research Elevated ornithine decarboxylase activity promotes skin tumorigenesis by stimulating the recruitment of bulge stem cells but not via toxic polyamine catabolic metabolites
