Andropause: What Happens to Men's Hormones After 40

Women have menopause — a well-defined hormonal transition with a clear medical framework, established treatments, and widespread awareness. Men have... what exactly?

The answer is andropause, sometimes called "male menopause" — though that term is somewhat misleading because the process is very different from what women experience. There's no abrupt hormonal cliff. No definitive event that marks the change. Instead, men undergo a gradual, steady decline in testosterone and other hormones that unfolds over decades, starting as early as the mid-30s.

It's subtle enough that most men don't recognize it's happening. They just notice that they feel different than they used to.

What Changes and When

Starting around age 30-35, testosterone levels decline approximately 1-2% per year. By age 50, a man's total testosterone may be 20-30% lower than it was at its peak. By 70, the decline can be 40-50%.

But testosterone isn't the only hormone shifting:

DHEA declines. Dehydroepiandrosterone, produced by the adrenal glands, drops steadily after age 30. DHEA is a precursor to both testosterone and estrogen, and its decline contributes to the overall hormonal shift.

SHBG increases. Sex hormone-binding globulin rises with age, binding more testosterone and making it biologically unavailable. So even if your total testosterone looks reasonable on a lab report, your free (active) testosterone may be considerably lower.

Growth hormone decreases. GH production declines about 14% per decade after age 30, contributing to changes in body composition, recovery, and sleep quality.

Estrogen may increase. As men gain body fat with age, aromatase activity converts more testosterone to estradiol. Some older men end up with relatively higher estrogen levels and lower testosterone — a combination that produces its own set of symptoms.

The net result is a hormonal environment that looks and feels fundamentally different from what it was at age 25.

How Andropause Feels

The symptoms of andropause develop so gradually that many men don't connect them to hormones at all. They attribute the changes to stress, aging, or just "getting older." Common experiences include:

Energy changes. Not just tiredness — a deeper sense of diminished vitality. The drive to tackle projects, exercise, or engage socially fades. Afternoon fatigue becomes the norm rather than the exception.

Body composition shifts. Muscle becomes harder to maintain and easier to lose. Fat accumulates around the midsection. Despite similar eating and exercise habits, your body simply responds differently than it used to.

Sexual changes. Reduced libido, less spontaneous desire, weaker erections, or longer recovery time between sexual encounters. These changes are often the first thing men notice — and the last thing they want to talk about.

Mood and cognitive shifts. Irritability, reduced patience, difficulty concentrating, mild depression, or a sense of emotional flatness. Some men describe it as losing their "edge" — the mental sharpness and confidence they used to take for granted.

Sleep disruption. Difficulty falling asleep, staying asleep, or waking unrefreshed. Sleep quality declines partly because testosterone and growth hormone — both involved in sleep architecture — are decreasing.

Reduced recovery. Workouts take longer to recover from. Injuries heal more slowly. General physical resilience drops.

Andropause vs. Menopause: Key Differences

It's important to understand why andropause isn't simply "male menopause":

| | Menopause | Andropause |

|---|---|---|

| Onset | Relatively abrupt (occurs over 2-5 years) | Gradual (unfolds over decades) |

| Hormone change | Near-complete loss of estrogen and progesterone | Slow, steady decline in testosterone |

| Universality | Happens to all women | Happens to all men, but severity varies |

| Diagnosis | Well-defined clinical criteria | No universally agreed-upon diagnostic threshold |

| Fertility impact | Fertility ends | Fertility may decrease but doesn't end |

The lack of a clear diagnostic line for andropause is part of why it receives less medical attention. There's no single blood level that defines it, and symptoms vary widely between individuals.

When to Get Evaluated

Consider a hormone evaluation if you're a man over 40 experiencing several of the symptoms described above — particularly if they've been present for more than a few months and aren't explained by other obvious causes.

A comprehensive evaluation should include:

• Total testosterone (drawn in the morning)
• Free testosterone
• SHBG
• Estradiol
• LH and FSH (to determine if the issue is testicular or pituitary)
• CBC (to check red blood cell levels)
• PSA (baseline prostate screening)
• Metabolic panel and lipids
• Thyroid function

These labs, combined with your symptom history, give a clear picture of what's happening hormonally and whether treatment makes sense.

Treatment Options

Not every man with age-related testosterone decline needs treatment. Some men have modest declines and feel fine. But for men with symptoms and confirmed low levels, there are effective options:

Testosterone replacement therapy (TRT) — via injection, gel, or patch — can restore testosterone to mid-normal range. Most men notice improvements in energy, mood, libido, and body composition within four to eight weeks.

Lifestyle optimization — resistance training, adequate sleep, stress management, and maintaining a healthy body weight can meaningfully support testosterone levels. These are worth pursuing whether or not you choose TRT.

Addressing contributing factors — sleep apnea, obesity, chronic stress, and certain medications can all suppress testosterone. Treating these underlying issues sometimes improves hormonal levels enough to resolve symptoms without TRT.

The Bottom Line

Andropause is real. The hormonal changes men experience with aging are measurable, progressive, and can meaningfully affect quality of life. It's not something you have to just accept as an inevitable part of getting older.

If you feel like you've lost a step — physically, mentally, or emotionally — and you can't quite explain why, your hormones may be part of the answer. A blood test can tell you. And if treatment is appropriate, the improvement can be significant.
