The Role of Seminal Calcium in Male Infertility

Concentrations of total calcium were analyzed in the seminal fluid of 20 fertile and 35 infertile men by the use of automated analyzer and commercial kit. Normozoospermic infertile men exhibited a significantly lower calcium level, compared to the fertile group. The lower calcium concentration determined in the oligo-azoospermic infertile men, was not significantly different when compared to the fertile men. In the subject and control groups, no significant correlations existed between seminal calcium and sperm density or percent motility. The data from our study strongly suggest that seminal calcium level has to be determined in normozoospermic infertile men, who also possess the asthenozoospermia problem.
