What it’s for
- Treatment of confirmed hypogonadism
Testosterone replacement for people with a clinically diagnosed hormone deficiency.
Purpose, evidence and practical considerations.
Clinical guidance supports treatment for appropriate patients with symptoms and repeatedly low testosterone. The benefits and monitoring requirements differ from using testosterone for performance or general longevity.
Confidence: strong
TRT requires diagnosis and monitoring. Risks include erythrocytosis, infertility, acne, edema, sleep-apnea worsening and formulation-specific adverse effects; cardiovascular and prostate decisions require individual clinical assessment.
Prescription testosterone replaces deficient endogenous hormone and activates androgen receptors. It can restore serum testosterone and related symptoms in appropriately diagnosed hypogonadism; it also suppresses pituitary gonadotropins and sperm production.
Regulatory status: prescription medication (Schedule III controlled substance in the US; androgen / anabolic steroid)
