feisty
Menopause for men is a phrase that gets used loosely, but the hormonal shift it points to is real. Unlike the female menopause, which is a defined biological event marked by the end of ovarian function, the male version is a gradual decline in testosterone that begins in a man's 30s and continues across decades. Doctors call it andropause, or late-onset hypogonadism. The colloquial label sticks because the symptom picture, fatigue, mood shifts, reduced libido, and disrupted sleep, overlaps enough with what women experience that the comparison makes intuitive sense.
What's actually happening in the male body
Testosterone levels in men drop by roughly 1 to 2 percent per year from around age 35. That's a slow gradient, not the sharp hormonal cliff women encounter during perimenopause. By a man's mid-50s, the cumulative drop can be significant enough to produce noticeable symptoms. The testes continue to produce some testosterone throughout life, which is why "menopause" is technically a misnomer. The male body doesn't stop producing sex hormones entirely.
The symptoms that get men through the GP door tend to cluster in a few areas. Energy is usually the first to go. Men describe it as a flatness that sleep doesn't fix. Muscle mass becomes harder to maintain. Body fat, particularly around the abdomen, increases even without changes in diet. Some men notice reduced motivation and a shorter fuse. Erectile function can become inconsistent. These aren't vague complaints: they're measurable biological changes tied to falling testosterone, and they compound over time if left unaddressed.
It's worth noting that not every man in his 50s experiences significant symptoms. Testosterone decline is universal; symptomatic andropause is not. The distinction matters because treatment decisions should be based on symptoms and blood levels together, not age alone.
Why the conversation has been slow to catch up
Women's hormonal health has begun to attract serious public attention. As the conversation around menopause has changed, clinicians and researchers are investing more in understanding hormonal transitions across the lifespan. Men's hormonal health has lagged behind, partly because the gradual onset makes it harder to identify, partly because men are less likely to seek help for symptoms that don't have an obvious physical cause.
There's also a cultural factor. Symptoms like low mood, low energy, and reduced libido sit in territory men are often told to push through. By the time a man describes his symptoms to a GP, he's typically been managing them quietly for two or three years. That delay matters because the longer low testosterone goes untreated, the more pronounced the downstream effects on bone density, cardiovascular health, and metabolic function.
How it's diagnosed
Diagnosis requires a blood test measuring total testosterone, usually taken in the morning when levels are highest. A single low result isn't enough. Most endocrinologists want two separate low readings, taken on different days, alongside a symptom profile. Other conditions, including thyroid dysfunction, depression, sleep apnoea, and type 2 diabetes, can produce a near-identical symptom picture and need to be ruled out first.
The threshold for "low" is contested. Most Australian labs flag total testosterone below 8 to 12 nmol/L as abnormal, but some men feel significant symptoms at levels that sit just above the clinical cutoff. That's why the symptom assessment carries as much weight as the number on the page.
What treatment looks like
Testosterone replacement therapy (TRT) is the primary clinical intervention when levels are confirmed low and symptoms are affecting quality of life. It's available in Australia as a gel, a patch, or an injection. Each delivery method has tradeoffs around convenience, absorption, and consistency of levels. A GP or endocrinologist will guide the choice based on the individual's health profile and preference.
TRT isn't appropriate for every man. Prostate cancer is an absolute contraindication. Men who want to maintain fertility need to consider alternatives, because exogenous testosterone suppresses the body's own production and reduces sperm count. Those situations call for a different treatment pathway, often involving drugs that stimulate the body's own hormone production rather than replacing it directly.
Outside of TRT, the lifestyle interventions with the strongest evidence are resistance training, sleep optimisation, and reducing visceral fat. These aren't consolation prizes. Strength training in particular has a direct effect on testosterone production and on the muscle and metabolic symptoms that come with its decline. Lifting heavy weights has robust support in the literature for this age group, in both men and women, and the benefits compound across years rather than weeks.
What men should actually do
The first step is a GP appointment and a morning blood test. Don't wait until symptoms are severe. If testosterone comes back in the normal range but symptoms persist, push for a full hormonal panel and a referral to an endocrinologist. Normal on paper doesn't always mean optimal in practice.
Beyond that, three habits move the needle more reliably than most supplements: structured resistance training at least 3 times per week, 7 to 8 hours of sleep prioritised consistently, and reduction of alcohol intake, which directly suppresses testosterone production. These changes don't require a prescription, and they work whether or not TRT is part of the picture.
The male hormonal transition is real, gradual, and addressable. The label "menopause for men" is imprecise, but it has done one useful thing: it's given men a frame for a conversation they were struggling to start.
