Testosterone therapy in older adults can boost libido and improve memory in men, while reducing mood disturbances in women. Further research is needed to fully understand its behavioral effects.

Area of Science:

  • Endocrinology
  • Gerontology
  • Behavioral Science

Background:

  • Testosterone levels decline with age in both men and women.
  • The "andropause" in men is characterized by a cluster of behavioral symptoms.
  • Behavioral effects of testosterone in older populations require further investigation.

Purpose of the Study:

  • To review the known behavioral effects of testosterone in older men and women.
  • To identify areas where more research is needed regarding testosterone's impact on behavior.

Main Methods:

  • Literature review of studies on testosterone and behavior in aging individuals.
  • Synthesis of findings regarding libido, sexual activity, mood, and cognition.

Main Results:

  • Testosterone demonstrably improves libido and sexual activity in both older men and women.
  • In older women, testosterone appears to decrease dysphoria.
  • In older men, testosterone enhances spatial memory and potentially verbal and working memory; effects on mood are less clear.

Conclusions:

  • Testosterone therapy shows promise for improving specific behavioral aspects in older adults.
  • Larger, well-designed studies are essential to definitively establish the behavioral benefits of testosterone in aging populations.
  • Further research should focus on elucidating the precise mechanisms and extent of testosterone's influence on behavior across different demographics.
