The Male Hormonal Transition Nobody Talks About
Andropause: what age-related testosterone decline actually looks like
Menopause — the point at which periods stop permanently, covered in full in the Women's Health guide — is a well-recognised, relatively abrupt hormonal transition. The male equivalent — sometimes called andropause, more accurately described as age-related testosterone decline — is real but far more gradual, which is part of why it's less commonly discussed and less reliably recognised.
How It Differs From Menopause
Rather than a relatively defined transition window, testosterone in men typically declines gradually from around the age of 30 onward, at a pace heavily influenced by the lifestyle factors covered in Section 2 — meaning two men of the same age can have meaningfully different trajectories depending on sleep, body composition, and activity levels, more so than is generally true of the female menopausal transition, which follows a more universal biological timeline.
Recognising It
Symptoms commonly include reduced energy, lower libido, mood changes, reduced muscle mass, and increased body fat — all of which overlap substantially with normal aging and other conditions, which is part of why the diagnosis requires bloodwork, not symptom-matching alone.
A single low reading isn't sufficient for diagnosis — clinical guidelines require confirmed, consistently low testosterone on repeat testing, generally alongside genuine symptoms, before a diagnosis of clinically significant hypogonadism is made[10].
Not every man with lower testosterone than he had at 25 has a medical condition requiring treatment — some decline is a normal part of aging, and the clinical threshold for treatment is deliberately more conservative than the popular framing around "low T" often suggests.
Section takeaway
Age-related testosterone decline in men is real, gradual, and heavily influenced by modifiable lifestyle factors — but it's a spectrum, not a universal medical condition, and diagnosis requires confirmed bloodwork and genuine symptoms, not just being older than you used to be.
