The term andropause suggests a male equivalent of menopause, which implies a defined hormonal transition with predictable timing and symptoms. That framing is misleading. Male hormonal aging is real, but it does not resemble menopause in its biology, its timeline, or its universality.
Understanding what is actually happening, and what is not, helps you evaluate the clinics and supplements that have built businesses around the term.
What menopause is, and why the analogy breaks down
Menopause is a discrete biological event. Ovarian function ends over a defined period, estrogen and progesterone fall sharply, and the reproductive capacity of the ovary is exhausted. It happens to essentially every woman who lives long enough, within a predictable age window.
Male hormonal aging looks nothing like this. Testosterone declines gradually, at roughly one to two percent per year after the thirties, and testicular function persists into old age. Many men in their seventies maintain testosterone levels in the normal range for young adult men. Men can father children into their eighties. There is no defined transition, no universal timing, and no equivalent hormonal cliff.
The more accurate clinical term for age-related testosterone decline is late-onset hypogonadism, and the diagnostic bar is higher than the marketing suggests.
What actually happens with age
Several things shift in male endocrine function over time:
- Total testosterone falls gradually
- Sex hormone binding globulin (SHBG) rises with age, which reduces free testosterone more than total testosterone would suggest
- The circadian rhythm of testosterone flattens, so the morning peak becomes less pronounced
- LH pulsatility changes, sometimes with elevated LH suggesting the testes are struggling to respond
- Estradiol can rise relative to testosterone, particularly with increased adiposity
The practical effect is that a subset of older men do develop symptomatic low testosterone, and they benefit from evaluation and, sometimes, treatment. But most symptoms attributed to andropause, fatigue, low libido, weight gain, mood changes, poor sleep, have multiple causes that are not primarily hormonal.
What is often misattributed
The symptoms of low testosterone overlap with the symptoms of many other conditions, and the overlap is what fuels overdiagnosis. Fatigue in a fifty-year-old man is more often the result of poor sleep, undiagnosed sleep apnea, or depression than of hormones. Weight gain is more often driven by declining activity and metabolic changes than by testosterone.
A reasonable differential for classic andropause symptoms includes:
- Sleep disorders, especially obstructive sleep apnea
- Depression, which is often underrecognized in middle-aged men
- Thyroid dysfunction
- Iron overload (hemochromatosis), which is more common than most men realize
- Medication side effects, particularly from statins, beta blockers, opioids, and SSRIs
- Chronic alcohol use
Any workup for suspected andropause that skips these is incomplete.
A morning testosterone level in the low-normal range and vague fatigue do not add up to a diagnosis. The AUA is explicit that testosterone therapy should be reserved for men with both consistent symptoms and testosterone levels confirmed low on two separate morning tests.
The commercial layer
Men's health clinics offering rapid testosterone prescriptions have proliferated, often with minimal workup and enthusiastic marketing. The pattern is recognizable: an online form, a single lab draw, and a prescription within days. This model is efficient but it bypasses the standard of care, misses the reversible causes, and commits men to lifelong therapy without a clear indication.
Testosterone therapy is not benign. It suppresses sperm production, raises hematocrit, and requires ongoing monitoring. Started for the wrong reasons, it does not solve fatigue or improve mood in men who do not actually have hypogonadism.
The bottom line
Male menopause is a marketing term rather than a medical one. Testosterone does decline with age, some men develop true late-onset hypogonadism, and treatment can help those men. But the majority of symptoms bundled under andropause have more common and more addressable causes. A careful workup respects that, and a clinic that skips it does not.
