Testosterone supplementation in men with low testosterone levels can improve spatial cognition, mood, and energy. This hormone replacement therapy offers benefits for both younger and older hypogonadal men.

Area of Science:

  • Neuroendocrinology
  • Cognitive Neuroscience

Background:

  • Testosterone influences gender-specific spatial recognition and age-related cognitive and mood declines.
  • Low testosterone levels are linked to depressive disorders and affect cerebral functions.

Purpose of the Study:

  • To investigate the role of testosterone in modulating cognitive functions and mood.
  • To examine the effects of testosterone supplementation on spatial cognition and mood in hypogonadal men.

Main Methods:

  • Analysis of testosterone's activation of the ventral processing stream during spatial tasks.
  • Assessment of spatial cognition and mood changes following testosterone administration in hypogonadal men.

Main Results:

  • Testosterone supplementation improved spatial cognition in younger and older hypogonadal men.

  • Reduced testosterone is associated with depression, partly influenced by androgen receptor genotype.
  • Testosterone therapy in hypogonadal men enhanced positive mood, vigour, and energy, with limited impact on aggression.

    • Conclusions:

    • Testosterone is a key modulator of cerebral functions, impacting cognition and mood.
    • Testosterone supplementation in hypogonadal men of all ages can enhance mood and cognitive performance.
