Andropause: What men need to know about midlife hormonal change

Andropause, sometimes called 'male menopause', is a term that has quietly crept into conversations about men’s health over the last decade.
But what does andropause actually mean? And how does male hormonal health really change in midlife?
This blog explains what andropause is, so you can have a clearer understanding of what’s happening beneath the surface.
What is andropause?
Andropause refers to the gradual, age-related decline in testosterone levels that occurs in men, typically from midlife onwards.
Andropause is not sudden or universal. It is slow, variable and highly individual.
From around the age of 30–40, testosterone levels decline by an average of 1% per year. For some men, this change is barely noticeable. For others, the effects can be more pronounced.
This gradual nature is important. There is no clear 'before' and 'after'. Instead, symptoms often creep in over years, which is one reason they’re frequently missed or dismissed.
Is andropause the same as male menopause?
Not really. The comparison is convenient, but biologically misleading.
In very simple terms, menopause (in women) involves a relatively rapid drop in oestrogen and the end of reproductive function. Andropause does not involve a sudden hormonal switch-off, nor does it mean that fertility ends.
Testosterone production continues throughout life. What changes is the amount available and how effectively the body uses it.
Factors like sex hormone binding globulin (SHBG) levels, inflammation, insulin resistance and stress all influence how much testosterone is actually active at tissue level.
This is why two men with the same blood testosterone level can feel completely different.
Common symptoms linked to andropause
Symptoms associated with andropause are often non-specific, which makes them easy to attribute to ageing, stress or lifestyle alone.
Commonly reported changes include:
Reduced energy or persistent fatigue
Lower libido or changes in sexual function
Loss of muscle mass or increased fat gain, particularly centrally
Low mood, irritability or reduced motivation
Poor sleep or non-restorative sleep
Brain fog or reduced concentration
Not every man experiences these symptoms, and experiencing them does not automatically mean that testosterone is low. There are other reasons why someone might be experiencing these symptoms.
What drives testosterone changes in midlife?
Age plays a role, but it is rarely the only factor.
Testosterone production is sensitive to overall metabolic health.
Excess body fat, particularly visceral fat, increases the conversion of testosterone to oestrogen.
Chronic stress raises cortisol, which suppresses testosterone production and contributes to wider changes in male hormone balance.
Fluctuations in blood sugars can impact testosterone levels.
Poor sleep disrupts the hormonal signalling that drives testosterone release.
Long-term conditions such as type 2 diabetes, cardiovascular disease and chronic inflammation are all associated with lower testosterone levels.
Certain medications can also affect hormone production or availability.
In other words, testosterone does not operate in isolation. It reflects what is happening in the wider system.
Blood tests and the limits of numbers
Testosterone is usually measured using blood tests, but interpretation is not always straightforward.
Total testosterone is often measured first, but this does not account for how much testosterone is bound to proteins like sex hormone-binding globulin (SHBG) and therefore unavailable to tissues.
Free or bioavailable testosterone tests can offer more insight, but reference ranges vary and symptoms do not always align neatly with numbers.
Timing matters too. Testosterone follows a daily rhythm, peaking in the morning. Testing outside this window can distort results.
This is one reason why a purely number-driven approach can miss the bigger picture.
Testosterone replacement therapy
Testosterone replacement therapy (TRT, also known as male HRT) is sometimes framed as either a miracle solution or something to fear. In reality, it sits somewhere in between.
For men with clinically low testosterone and significant symptoms, TRT can improve quality of life.
But it is not a lifestyle substitute, and it comes with considerations around long-term use, fertility, cardiovascular risk and ongoing monitoring.
Crucially, TRT addresses hormone levels, not the underlying drivers that may have contributed to their decline in the first place. This distinction is often lost in public conversation.
Why personalisation matters in male hormonal health
Two men of the same age can have very different hormonal experiences. Genetics, body composition, stress load, sleep quality, diet, exercise and life stage all influence hormonal health.
This is why generic advice often falls flat. Supporting male hormones is rarely about one intervention.
Understanding the full picture matters far more than chasing an idealised testosterone level.
Andropause as part of midlife health
Midlife is a period of transition for everyone, not just hormonally but metabolically and psychologically too.
Hormonal changes often intersect with career pressure, caring responsibilities, reduced recovery capacity and changing priorities.
Seen through this lens, andropause is not a failure or a flaw. It is a signal that invites a closer look at how the body is responding to the life it’s living.
Where to go from here
If symptoms resonate, or if you’re curious about your hormonal health, the most useful next step is not guessing or self-prescribing solutions. It’s understanding your individual context.
That’s where personalised, evidence-based support comes in.
