research The Selective Androgen Receptor Modulator GTx-024 (Enobosarm) Improves Lean Body Mass and Physical Function in Healthy Elderly Men and Postmenopausal Women: Results of a Double-Blind, Placebo-Controlled Phase II Trial
Enobosarm significantly increased muscle mass and improved physical function in elderly men and postmenopausal women without serious side effects.
research Beyond Goosebumps: Does the Arrector Pili Muscle Have a Role in Hair Loss?
The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.
research Testosterone Supplementation for Aging-Associated Sarcopenia
Testosterone supplements can increase muscle mass and strength in older men with low levels, but long-term effects and risks need more research.
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 A Phase IIA Randomized, Placebo-Controlled Clinical Trial to Study the Efficacy and Safety of the Selective Androgen Receptor Modulator (SARM), MK-0773 in Female Participants with Sarcopenia
MK-0773 safely increased muscle mass but did not improve muscle strength or function in elderly women with sarcopenia.
research Beyond Testosterone Cypionate: Evidence Behind the Use of Nandrolone in Male Health and Wellness
Nandrolone might increase muscle mass with fewer side effects than testosterone but could cause erectile dysfunction and needs more research.
research The Use of Neurotoxins in the Male Face
Men need higher doses of botox than women and a different approach for facial aesthetics due to their unique facial features and muscle mass.
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 The Impact of Gender Affirming Hormone Therapy on Physical Performance
Gender-affirming hormone therapy improves physical performance in trans men to the level of cisgender men, while in trans women, it increases fat mass and decreases muscle mass, with no advantage in physical performance after 2 years.
research Novel Uses for the Anabolic Androgenic Steroids Nandrolone and Oxandrolone in the Management of Male Health
Nandrolone and oxandrolone could help treat male health issues like muscle loss and low testosterone.
research The Pathophysiology of the Male Aging Face and Body
