Higher DHT levels are linked to worse heart changes in severe aortic valve stenosis patients.
research Pathogenesis of androgenetic alopecia
Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.
research Post-Finasteride Syndrome (PFS) Update: Point/Counterpoint
Finasteride's link to health issues like male breast cancer, infertility, and prostate cancer needs more research through placebo-controlled trials to confirm.

Finasteride and dutasteride are effective for male hair loss and enlarged prostate but may cause reversible sexual side effects.
research Anabolic effects of testosterone are preserved during inhibition of 5α-reductase
Testosterone can build muscle and bone without enlarging the prostate when a specific enzyme is blocked.
research Effects of lifelong testosterone exposure on health and disease using Mendelian randomization
Higher testosterone levels can increase the risk of certain diseases like type 2 diabetes in women and prostate cancer in men, but can also protect against autoimmune diseases and hair loss. It also affects body fat and bone density.
