Effects on behavior of modulation of gonadal function in men with gonadotropin-releasing hormone antagonists.

ABSTRACT

The effects of acute gonadal suppression on sexual function and behavior were studied in eight normal men. Administration of a newly developed, potent gonadotropin-releasing hormone antagonist induced azoospermia and reduced levels of serum testosterone, luteinizing hormone, and follicle-stimulating hormone. These effects coincided with a reduction in outward-directed aggression in all men. Self-reported measures of anxiety and sexual desire revealed less consistent change over time. Measures of anger control, inward-directed anger, and affective state were unaffected.
