title: The effects of caffeine and theophylline on the triple adenosine triphosphatase enzyme activities of spermatozoa from males with oligoasthenospermia.
abstract: The triple ATPase activities of washed spermatozoa of oligoasthenospermic men (but not of normals) were enhanced by the addition of caffeine and theophylline, which are known to have a stimulating effect on sperm motility. The biochemical mechanism of action of caffeine and theophylline on sperm homeostasis is discussed.
