Male Menopause After 40 and Gynecomastia:
Is There a Connection?
1.
Male menopause is medically known as LOH syndrome (Late-Onset Hypogonadism). Unlike menopause in women, it progresses gradually rather than abruptly, so many men are simply unaware of it.Male Menopause: What Is It, Medically Speaking?
The key factor is declining testosterone. From the late 30s onward, total blood testosterone is known to decrease by about 1–2% per year, and by the 60s it can fall to 30–50% of young-adult levels. A total testosterone level of 300 ng/dL or below is considered low testosterone, and when free testosterone declines along with it, symptoms tend to become more pronounced.
In this process, the ratio of testosterone to estrogen shifts. The aromatase enzyme found in body fat converts the remaining testosterone into estrogen, creating a state of relative estrogen dominance. This is the mechanism that stimulates the mammary gland tissue.

Male menopause and gynecomastia have overlapping causes, but their symptoms present differently. If you are experiencing both, use the table below to see how they differ.
Male Menopause vs. Gynecomastia: How Do the Symptoms Differ?
| Category | Male Menopause (LOH Syndrome) Symptoms | Gynecomastia Symptoms |
|---|---|---|
| Main Changes | Overall decline in condition (fatigue, reduced motivation) | Localized changes in the chest area |
| Physical Symptoms | Reduced muscle strength, increased abdominal fat, decreased libido | Protruding tissue beneath the nipple, tenderness, increased nipple sensitivity |
| Psychological Symptoms | Lethargy, poor concentration, sleep disturbances | Self-consciousness about the chest, social avoidance |
| Diagnostic Criteria | Blood testosterone of 300 ng/dL or below, accompanied by symptoms | Palpable glandular tissue 2 cm or more in diameter, confirmed by ultrasound |
| Course | Systemic symptoms fluctuate with hormone levels | Unlikely to resolve on its own once fibrosis has progressed |
Check Point
What to Check When Gynecomastia Is Suspected After 40
- ✓Whether your chest area has changed noticeably within the past one to two years
- ✓Whether you can feel firm tissue when pressing beneath the nipple
- ✓Whether menopause symptoms such as fatigue, decreased libido, or reduced muscle strength are also present
- ✓Whether any medications you are currently taking could potentially cause gynecomastia
- ✓Whether you have liver function abnormalities or a history of chronic alcohol use

Gynecomastia that appears after 40 is hard to assess by looking at the chest alone. If changes in your chest are worrying you, it is important to check your hormone status first.Menopause-Related Gynecomastia May Call for a Different Approach
Blood tests measuring total testosterone, free testosterone, estradiol, LH, and FSH can help determine whether hormonal changes are contributing to the gynecomastia. If estradiol is 40 pg/mL or higher while testosterone is low, there is a good chance that a hormonal imbalance is involved in stimulating the glandular tissue.
If a hormonal abnormality is confirmed, correcting it takes priority, sometimes alongside medication changes or lifestyle improvements. However, if fibrosis of the mammary gland tissue has already progressed, the tissue is unlikely to shrink even after the hormones are corrected. In such cases, a surgical approach may be considered, and it is standard practice to stabilize hormone levels before proceeding with surgery.
If changes in your chest area concern you after 40, it is best to look at menopause symptoms and gynecomastia together. Combining hormone testing with a chest ultrasound allows the cause to be identified more accurately. In most cases, once the cause is found, the right path forward becomes clear — so try not to worry too much.
