Core

Testosterone & aging

Total testosterone declines gradually with age; symptoms overlap sleep apnea, depression, thyroid disease, and medication effects—test before buying marketing.

When to evaluate

Morning total testosterone (sometimes repeated), symptom review, exam for secondary causes—obesity, opioids, pituitary issues.

TRT trade-offs

Benefits for clearly hypogonadal men under supervision; risks include erythrocytosis, fertility suppression, acne, possible cardiovascular signals in some populations—specialists weigh individual context.

Before supplements

OTC “boosters” lack consistent evidence and may harm liver—fix sleep apnea and mood first when present.

Life-stage education for adult men—not personalized medical advice or emergency triage.
