Abstract
ATP and ADP were measured by a bioluminescent method in human ejaculated spermatozoa from 31 normal donors and oligozoospermic patients. ATP and ADP expressed for the sperm total number were significantly correlated (P < 0.001). ATP and ADP levels were found significantly correlated with the total motile spermatozoa and with the total viable cells (respectively P < 0.001 and P < 0.001 for ATP and P < 0.001 and P < 0.001 for ADP). ATP/ADP ratio was found significantly lower in subjects with sperm motility less than 50% (P= 0.024) and total viable cells less than 80% (P= 0.026).
