Summary

Aging men experience a gradual decline in testicular function, with testosterone levels dropping significantly by age 75. Testosterone therapy may help manage age-related symptoms, but long-term effects require further study.

Area of Science:

  • Andrology
  • Gerontology
  • Endocrinology

Background:

  • Male reproductive function declines gradually with age, unlike the abrupt cessation in women.
  • Testicular endocrine and exocrine functions decrease progressively in aging men.

Purpose of the Study:

  • To examine the effects of aging on male gonadal function.
  • To assess the role of declining testosterone levels in age-related symptoms.
  • To evaluate the efficacy and safety of testosterone supplementation in elderly men.

Main Methods:

  • Analysis of age-related changes in male endocrine and exocrine testicular function.
  • Correlation studies between plasma testosterone levels and associated symptoms.
  • Review of testosterone supplementation therapy outcomes and side effects.

Main Results:

  • Testosterone levels decrease with age, with many men over 75 having below-normal levels.
  • Age-related symptoms in men often resemble those of young hypogonadal males.
  • Testosterone supplementation shows potential benefits for some symptoms, with minimal side effects when physiological levels are maintained.

Conclusions:

  • Declining testosterone is a co-determinant of age-related symptoms in men.
  • Testosterone therapy is promising but requires more long-term, large-scale studies for routine recommendation in elderly men.
  • Clinical prostatic carcinoma is a contraindication for testosterone supplementation.
