Andropause, often called male menopause, is the slow drop in testosterone that can bring low energy, a weaker sex drive, poor sleep, mood changes, lost muscle and a thicker middle. It isn't a sudden switch like female menopause. It's gradual, it hits men differently, and the same symptoms can come from other things. Knowing the signs is the first step. Getting the right test at the right time is the second.
If you're a man who feels the shift coming, or a wife or partner who sees it, this guide gives you the full picture. It covers the symptoms, the look-alikes, how testosterone is actually measured, and what you can do before bigger decisions are on the table.
TL;DR
- Common signs include fatigue, lower sex drive, fewer spontaneous erections, low mood, brain fog, poor sleep, less muscle and more belly fat.
- Testosterone drifts down about 1% a year after 40, but most older men still land in the standard range.
- These symptoms are not specific to low testosterone. Sleep, weight, medications and stress can cause the same picture.
- Confirming low testosterone takes two early-morning blood tests, plus symptoms, with a healthcare professional.
- Daily habits come first. That's where a simple restoration routine fits.

What andropause actually is
"Andropause" is a popular word, not a clean medical diagnosis. Doctors usually talk about low testosterone, testosterone deficiency or late-onset hypogonadism. Stony Brook Medicine describes andropause as a gradual decline in hormones, especially testosterone, that typically starts around age 40, with a drop of roughly 1 percent a year.
That word "gradual" matters. Women go through menopause with a fairly clear hormonal turn. Men don't. Mayo Clinic notes that testosterone levels generally fall about 1% a year after 40, yet most older men remain within the standard range. Only about 10% to 25% have levels thought to be low.
So you can feel the slide without being "low" on paper. And you can have a low number without feeling much at all. That's why symptoms and testing have to be read together.
The main signs of andropause
Most men don't notice one dramatic change. They notice a pile-up. The energy that used to come automatically doesn't. Recovery takes longer. The drive you took for granted goes quiet.
Sexual symptoms
These are the most telling. Mayo Clinic lists lowered sexual desire and activity, erectile dysfunction or fewer erections, breast tenderness or swelling, infertility, height loss, low bone density and hot flashes or sweats as symptoms that suggest low testosterone. The Endocrine Society also names loss of spontaneous erections, such as morning erections, and shrinkage of the testes.
Cleveland Clinic notes that decreased libido, depression, erectile dysfunction, delayed ejaculation and diminished facial and body hair growth are more specific indicators than general tiredness. If your desire has genuinely dropped, take that seriously.
Physical symptoms
- Persistent fatigue that sleep doesn't fix
- Lower muscle mass and strength, even when you train
- More body fat, especially around the abdomen
- Insomnia or broken sleep
- Hot flashes or sweats in some men, usually when levels are quite low
Stony Brook lists low energy, reduced muscle mass and strength, increased abdominal fat, insomnia and lower sex drive among the physical signs. UC San Diego Health adds that low testosterone affects an estimated 40% of men over 45, which is why so many men are asking about it.
Mood and mental symptoms
This is the part many men miss, and the part wives and partners often see first. Stony Brook lists mood swings or irritability, sadness or depression, trouble focusing or "brain fog," and a drop in motivation or confidence. Mayo Clinic puts less energy, motivation and confidence on the same list.
If your husband seems tired, flat or disconnected, it may not be about you. It may not be his character either. Something real could be going on.
Long-term and less obvious signs
Mayo Clinic's page on hypogonadism says early symptoms might include less sex drive, less energy and depression. Over time, men can see erectile dysfunction, infertility, less hair on the face and body, less muscle mass, breast enlargement and bone loss. Those later signs are why you shouldn't ignore the early ones.
Symptom checklist: a quick self-check
Sit down with this list. Be honest. Nobody's grading you.
| Area | What you might notice | How specific is it? |
|---|---|---|
| Sex drive | Less interest, fewer spontaneous or morning erections | More specific |
| Performance | Erectile changes, delayed ejaculation | More specific |
| Body | Less muscle, more belly fat, less body hair | Moderate |
| Energy | Tired all day, slow recovery | Low, many causes |
| Mood | Irritable, flat, low motivation | Low, many causes |
| Thinking | Brain fog, poor focus | Low, many causes |
| Sleep | Trouble falling or staying asleep | Low, many causes |
The last four rows overlap with almost everything else in a busy man's life. That's the catch, and it's the next section.
Why these symptoms can fool you
Here's the honest truth. Mayo Clinic explains that symptoms related to low testosterone aren't specific to it. Age, medicines and other conditions can cause them too, and a body mass index of 30 or higher can cause a similar picture.
The Endocrine Society says low testosterone itself can result from testicular injury or infection, cancer treatment, medications such as opiate painkillers and corticosteroids, pituitary problems, chronic liver or kidney disease, obesity, sleep disorders, type 2 diabetes, HIV/AIDS, genetic conditions and anabolic steroid use.
So before you decide it's all testosterone, run the basics:
- Sleep. Are you getting enough quality hours? Snoring and daytime sleepiness deserve a conversation about sleep apnea.
- Weight. Are you carrying more around the middle than you did five years ago?
- Medications. Did the fatigue start after a new prescription?
- Mood. Is this low mood or low testosterone, or both? Our guide on telling depression from low testosterone with a morning test walks through it.
- Stress and alcohol. Both drag on sleep, drive and recovery.
A urologist at MultiCare says that habits good for overall health, like quality sleep, regular exercise and less alcohol, also support sexual health. Nothing glamorous. It works as a foundation anyway.
Low libido in younger men has its own set of triggers. If you're still in your 30s, read how sleep, stress and two morning tests change the picture.
How low testosterone is actually confirmed
Symptoms alone can't diagnose it. Neither can one lab result. The American Urological Association guideline says diagnosis requires two total testosterone measurements on separate occasions, both early in the morning, preferably from the same lab and method. Testosterone deficiency is diagnosed only when a low total testosterone is combined with symptoms or signs.
Why mornings? Mayo Clinic says testosterone is usually highest then, so blood testing is typically done between 8 and 10 a.m., sometimes on more than one day. Clinicians who care about the details of sampling and assay timing look at protocol design and assay timing closely for the same reason: when and how you measure changes what you see.
The Endocrine Society adds that testosterone changes hour to hour, and can dip temporarily with too much exercise, poor nutrition, severe illness and certain medications. That's why one bad reading proves little.
What the numbers mean
The Endocrine Society says normal adult male levels fall between 300 and 1,000 ng/dL depending on age and lab. Cleveland Clinic reports that the AUA supports a total testosterone cutoff under 300 ng/dL, with at least two low readings taken two to three weeks apart. A 2026 review in the Journal of Endocrinological Investigation notes that diagnostic thresholds for late-onset hypogonadism are not universally accepted, and different societies use different cutoffs.
Translation: your number matters, but so do your symptoms, your history and your doctor's judgment. For a plain-English walk through ranges, see normal testosterone levels in men. To avoid wasting a draw, read how to avoid lab mistakes with two morning tests.
If a first result is low, Mayo Clinic says further testing can look for the cause, including pituitary hormones, semen analysis and imaging.
When to talk with a healthcare professional
Don't wait for a crash. Talk to a primary care doctor, urologist or endocrinologist if:
- Your sex drive has dropped and stayed down
- You've lost spontaneous erections or have erectile trouble
- You have breast tenderness or swelling, height loss or a fracture from a minor fall
- Your energy, mood or focus has changed and nothing explains it
- You're on opioids, steroids or other medicines that can affect hormones
MedlinePlus says that some symptoms may be a normal part of aging, but having no interest in sex is not usually normal, and it advises talking to your provider if symptoms bother you. Mayo Clinic adds that experts suggest testing older men only if they have symptoms, and repeating a first low result to confirm it.
If depression has you thinking dark thoughts, don't wait on a hormone test. Call or text 988, the Suicide and Crisis Lifeline, or see a doctor right away.
What treatment looks like, and where habits come in
If your doctor confirms testosterone deficiency, treatment is a medical decision. Cleveland Clinic says it's indicated when criteria are met, symptoms are present and the patient understands the risks and benefits. If another condition explains the deficiency, that condition should be treated first.
MedlinePlus notes that testosterone replacement therapy may help if you have low testosterone, but it's avoided in men with prostate or breast cancer and carries a higher risk of high blood pressure. If you notice no change after 3 months, it's less likely to help. Researchers writing in PMC add that lifestyle measures such as weight loss and better control of other conditions can lead to clinical improvement and a modest rise in testosterone in men with functional hypogonadism.
One more safety note. The MultiCare urologist advises talking to a doctor before taking testosterone supplements, since products touted online aren't tested or regulated by the FDA.

A routine you can actually stick with
You don't need a perfect life. You need a repeatable one. Start here:
- Protect your sleep. Same bedtime, dark room, no screens in bed.
- Get morning light. Our piece on circadian steps for testosterone explains why mornings matter.
- Lift something heavy. Two or three times a week.
- Cut back on alcohol. Your recovery will tell you why.
- Build a morning anchor. Here are five morning steps that protect testosterone.
For the bigger picture, read about morning testosterone, sleep, strength and at-home red light.
For her: what to look for in your husband
You may be the first to see it. He's quieter. He's short with the kids. He's tired by 7 p.m. and pulling away from you. He doesn't say why because he doesn't know.
Here's what helps. Don't open with "something's wrong with you." Open with "I miss you." Then suggest a checkup with bloodwork, done in the morning. The signs worth mentioning are the ones that repeat: low drive, low mood, low energy, poor sleep, less confidence. Our article on low testosterone and marriage explains why two tests won't fix the disconnect on their own, and how to talk about it. And if confidence is the sore spot, see what 27 trials show about testosterone and confidence.
Our view: you haven't lost it
We hear the same story every week. A man in his late 30s or 40s says he feels the shift. Not a crash. A fade. The tank that used to fill overnight doesn't anymore.
And the first answer he gets is often "just get the shot." We think men deserve more than that as a first step.
Here's what we believe. Before bigger decisions are on the table, you should understand your body, get the right morning bloodwork and protect what you still have. We are not a clinic. We are not TRT. We don't diagnose, and we don't tell men they're broken. If your symptoms are severe, see a doctor.

FAQ
What are the most common andropause symptoms?
The usual list is low energy, lower sex drive, fewer spontaneous erections, low mood, trouble focusing, poor sleep, less muscle and more body fat. Mayo Clinic lists these among the symptoms that suggest low testosterone. Sexual changes are the more specific ones. Fatigue and mood alone have many possible causes.
Is male menopause the same as female menopause?
No. Women's hormones fall over a relatively short window. Men's testosterone slides gradually, about 1% a year after 40, according to Mayo Clinic. Many men stay in the standard range for life. That's why doctors look at symptoms and repeat blood tests rather than age alone.
At what age do signs of andropause start?
MedlinePlus says testosterone may start to slowly decrease naturally around age 30 to 40. Most men notice symptoms later, in their 40s and beyond. Some feel changes sooner, often alongside poor sleep, weight gain or stress.
What test confirms low testosterone?
Your doctor will order total testosterone on two separate early-morning blood draws. The AUA guideline says a diagnosis also requires symptoms or signs. A single result isn't enough, since levels shift through the day.
Can lifestyle changes help with these symptoms?
For many men, habits are the first place to start. Researchers note that weight loss and better management of other conditions can improve symptoms and modestly raise testosterone in functional hypogonadism. Sleep, strength training and less alcohol are the basics. Talk to your doctor if symptoms persist.
