Bone mineral density (BMD) declines in men with age. Estrogen levels correlate positively with BMD, suggesting estrogens may regulate bone formation in males.

Area of Science:

  • Endocrinology
  • Gerontology
  • Osteology

Background:

  • Bone mineral density (BMD) is crucial for skeletal health.
  • Age-related changes in BMD are well-documented in women, but less so in men.
  • Hormonal influences on bone metabolism in aging males require further elucidation.

Purpose of the Study:

  • To investigate the relationship between aging, bone mineral density, and sex hormone levels in men.
  • To explore the potential role of estrogens in regulating bone metabolism in males.

Main Methods:

  • Dual-energy X-ray absorptiometry (DEXA) was used to measure BMD in the radius of 200 men aged 40 and above.
  • Serum levels of testosterone (Ts), dihydrotestosterone (DHT), and 17-beta estradiol (E-2) were measured.
  • Patients were stratified into four age groups: 40-49, 50-59, 60-69, and 70+ years.

Main Results:

  • BMD significantly decreased with advancing age in the male participants.
  • A positive correlation between BMD and 17-beta estradiol (E-2) levels was observed (p < 0.05).
  • This positive correlation between BMD and E-2 tended to decrease with age.

Conclusions:

  • Bone mineral density declines in aging men.
  • Estrogens, specifically 17-beta estradiol, may play a significant role in regulating bone formation (osteogenesis) in males.
  • Further research is warranted to confirm the role of estrogens in male bone health.
