Men in their 30s and 40s often notice changes that are easy to attribute to ‘just getting older’: less energy, declining motivation, reduced libido, increased body fat — especially around the abdomen — difficulty building muscle, and mood changes including irritability or low-grade depression. This is andropause — the gradual male hormonal decline — and it’s both more common and more treatable than most men realize.
What Is Andropause?
Unlike the relatively abrupt hormonal shift of female menopause, andropause is a gradual decline in testosterone and other androgens that typically begins in the mid-to-late 30s. Testosterone declines approximately 1-2% per year after age 30, and DHEA (a precursor hormone) often declines even earlier. By their mid-40s, many men have testosterone levels that are technically ‘in range’ but at the low end — a range established from young, healthy adults that doesn’t account for individual optimization.
Critically, andropause isn’t just about total testosterone. Elevated SHBG (sex hormone-binding globulin) with age means more testosterone is bound and unavailable to tissues. Aromatization — the conversion of testosterone to estrogen — increases with body fat, creating an unfavorable ratio that independently drives symptoms. And chronic stress, sleep deprivation, and toxic exposures — particularly xenoestrogens from plastics, pesticides, and personal care products — can suppress testosterone production regardless of age. (See the Endocrine Society’s clinical guidelines on male hypogonadism for reference.)
Why This Is More Than a Lifestyle Issue
Low testosterone has real health consequences beyond symptoms. It increases cardiovascular risk, accelerates bone density loss, impairs insulin sensitivity, drives cognitive decline, and is associated with depression and anxiety. Treating andropause is not about vanity — it’s about longevity and quality of life.
Functional medicine evaluates not just testosterone levels but the entire hormonal ecosystem and the upstream factors suppressing healthy androgen production — so we can correct the cause, not just supplement around it. (Research on testosterone, metabolic syndrome, and cardiovascular risk via PubMed continues to grow.)
How I Evaluate and Address Andropause
Andropause is not inevitable — and it’s certainly not untreatable. Here’s how I approach male hormonal health:
- Comprehensive male hormone panel: total and free testosterone, SHBG, estradiol, DHEA-S, LH, FSH, and prolactin
- Thyroid full panel — thyroid dysfunction in men is underdiagnosed and powerfully suppresses testosterone
- Metabolic evaluation: fasting insulin, HbA1c, full lipids — insulin resistance is a potent testosterone suppressor
- Xenoestrogen and heavy metal assessment — environmental hormone disruptors are a major contributor
- Sleep evaluation — testosterone is primarily produced during deep sleep; sleep apnea devastates levels
- Nutritional assessment: zinc, magnesium, vitamin D — critical cofactors for testosterone synthesis
- Individualized testosterone optimization strategies including lifestyle, botanical, and bioidentical hormone support when appropriate
