Semen magnesium levels in fertile and infertile subjects.

Semen samples of 37 fertile and 45 infertile subjects were analyzed for magnesium level by atomic absorption spectrophotometry. The mean semen magnesium level of fertile subjects was found to be 11.9 +/- (SD) 3.0 mg/100 ml and that of infertile subjects 6.9 +/- 2.1 mg/100 ml. It was concluded that semen magnesium may be a good criterion for prostate function.
