Is andropause real?
Andropause is real as a description of aging, but it is not a medical diagnosis, and it does not work like menopause. In women, estrogen production stops over a few years. In men, testosterone usually drifts down slowly over decades, and most men stay inside the normal range for life.
The medical term for the problem people mean is late-onset hypogonadism: testosterone that has fallen low enough to cause symptoms, in an older man without another obvious cause. The Endocrine Society describes hypogonadism as low testosterone with signs and symptoms, not low testosterone alone. Some men also hear the phrase “male HRT”, which our page on whether HRT for men is the same as TRT untangles.
The useful question is not whether you are going through andropause. It is whether your symptoms come from ordinary aging, from a true deficiency, or from something else entirely.
Normal aging: the slow drift
Testosterone in healthy men falls slowly, at roughly 1 percent a year from about 40 onward. Some of the most detailed long-term data come from the Massachusetts Male Aging Study, which followed more than 1,100 men aged 40 to 70 for 7 to 10 years. Comparing men of different ages, total testosterone was about 0.8 percent lower per year of age. Following the same men over time, it fell about 1.6 percent a year, and the free, usable fraction dropped faster, about 2 to 3 percent a year, as SHBG climbed.
That steeper fall within individual men is telling. The authors suggested that new illness speeds up the decline, and men in apparent good health had androgen levels 10 to 15 percent higher than their peers. In other words, much of what gets called andropause tracks with weight gain, chronic disease and medicines as much as with birthdays.
| Feature | Expected aging | Late-onset hypogonadism |
|---|---|---|
| Speed | Gradual, over decades | Can be gradual or faster |
| Morning total testosterone | Usually stays in the normal range | Consistently low on repeat testing |
| Sexual symptoms | Mild, variable | Persistent loss of desire, morning erections, erectile function |
| Tied to illness or weight | Often | Often, and sometimes reversible |
| Usual response | Lifestyle and monitoring | Treatment discussion if no reversible cause |
Our chart of normal testosterone levels by age shows how wide the normal range stays into later life.
What true late-onset hypogonadism looks like
Late-onset hypogonadism has a recognizable pattern: specific sexual symptoms plus testosterone that is low on more than one morning test. The European Male Ageing Study surveyed 3,369 men aged 40 to 79 to find which symptoms truly tracked testosterone. Only three did so as a syndrome: poor morning erections, low sexual desire and erectile dysfunction.
The researchers proposed a definition that is still widely cited as a reference point: at least three sexual symptoms, a total testosterone under 11 nmol/L (about 320 ng/dL), and a free testosterone under 220 pmol/L (about 64 pg/mL). Fatigue, low mood and reduced vigor were linked to testosterone too, just not tightly enough to diagnose anything.
Men whose numbers land just above the line belong in a separate conversation, covered on our page about borderline low testosterone.
How it is evaluated: questionnaire plus morning labs
The evaluation pairs a structured symptom questionnaire with blood drawn in the early morning, because neither works alone. A questionnaire organizes vague complaints into a clear list, shows which symptoms are sexual and which are general, and gives a baseline to compare against later. It cannot diagnose anything, because the same answers come from depression, poor sleep and thyroid disease.
The labs carry the weight:
- Total testosterone, early morning, repeated if low.
- Free testosterone and SHBG, since SHBG rises with age and can hide a low free level.
- LH and FSH, to show whether the testes or the pituitary signal is the weak link.
- PSA, hematocrit and estradiol, the safety baseline before any treatment talk.
- Thyroid, glucose and lipids when symptoms point beyond hormones.
Treat or monitor?
For many older men, monitoring is the right first answer. The Endocrine Society suggests against routinely giving testosterone to all men 65 or older with low levels, and instead recommends individual decisions for men with symptoms and consistently low morning testosterone, after a clear discussion of risks and benefits.
The largest set of trials in older men shows what treatment can and cannot do. In the Testosterone Trials, 790 men aged 65 and older with low levels used testosterone or placebo gel for a year. Testosterone moderately improved sexual function and slightly improved mood, but it did not improve energy or walking distance in the physical function trial. Our summary of the Testosterone Trials goes through the details, and can men over 65 start TRT? covers the age question directly.
Before either path, it pays to look for causes that are not about age at all. Long-term opioid or steroid use, untreated sleep apnea, a recent jump in weight, poorly controlled diabetes and heavy drinking can all lower testosterone in an older man, and each has its own fix. Treating testosterone while one of these is running in the background tends to disappoint.
Monitoring is not doing nothing. It means a repeat morning test on a schedule, work on weight, sleep, alcohol and strength training, and a fresh look if sexual symptoms worsen or the numbers fall.
Signs that need prompt attention
Midlife hormone changes are gradual, so anything sudden needs a different response. Call 911 for chest pain, shortness of breath or signs of a stroke. Seek same-day care for a new severe headache with vision changes, a lump or painful swelling in a testicle, or blood in the urine. Thoughts of self-harm call for an immediate call or text to 988.
How Ultimate Male sorts aging from hypogonadism
At our San Gabriel and Downey clinics, the first job is to separate the drift every man experiences from a deficiency worth treating. A free 10-minute call sets up a morning draw on site, and results return within 24 to 48 hours.
In a one-on-one visit, a PA-C or MD reviews your symptom questionnaire against your labs and your health history, including weight, sleep and medicines. If the pattern fits late-onset hypogonadism and there is no reversible cause, you will talk through testosterone therapy, its monitoring and its trade-offs. If it fits ordinary aging, you leave with a monitoring plan and specific steps instead. Men weighing their options at this stage of life may also find our page for men over 50 useful.
