Testosterone and its metabolite dihydrotestosterone (DHT) are both androgens. Their effects — on hair follicles, prostate, skin, and other tissues — depend on receptor activity and tissue-specific biology, not a simplistic good-versus-bad label.
What this means in context
Health information becomes more useful when the question, the evidence, and the limit of the evidence stay together. This Signal Library note is designed to show the shape of the evidence without turning it into a self-diagnosis or a generic action plan.
Testosterone and its metabolite dihydrotestosterone (DHT) are both androgens. Their effects — on hair follicles, prostate, skin, and other tissues — depend on receptor activity and tissue-specific biology, not a simplistic good-versus-bad label. The right next question can depend on symptoms, history, medications, personal goals, and clinical context.
A circulating hormone measurement cannot by itself predict hair loss, fertility, or other tissue-specific outcomes. DHT-blocking interventions carry their own tradeoffs.
How Corhack fits
Corhack is a men's health tracking app that helps you record the day-to-day context around sleep, meals, training, tasks, and personal goals. It does not diagnose, prescribe, interpret laboratory tests, or predict an individual health outcome.
