Abstract

Recent clinical and epidemiological studies worldwide suggest an increasing incidence of male factor infertility (MFI). Paucity of information on the biochemical analysis of seminal fluid in Sri Lanka prompted undertaking a pilot study to establish a clinical marker for the male fertility status in Sri Lanka based on the level of the cytokine, macrophage migration inhibitory factor (MIF) in seminal fluid, an area hitherto unexplored locally. The analysis was carried out on the semen samples of infertile males (N = 61) where age matched individuals (N = 30) with proven past paternity served as controls. D-dopachrome tautomerase assay was performed to assess the MIF level in semen while other seminal fluid parameters were assessed according to the standard WHO criteria. The present study revealed an abnormal biphasic profile of MIF in the seminal fluid of individuals with impaired sperm parameters, which was either significantly below or above the range of MIF tautomarase activity typical of normal fertile men (p < 0.000). This is the first report in a Sri Lankan population. The receiver operating characteristic (ROC) plot analysis established a cutoff point of 3.375 μg MIF/mL of semen (at 90 % sensitivity: 81.2 % specificity; 0.923 accuracy) to differentiate fertile from infertile males (excluding azoospermics and severe oligozoospermics). The MIF concentrations significantly correlated with the semen pH in the azoospermic and severe oligozoospermic group. As MIF was clearly indicative of the male fertility status by estimates of sensitivity and specificity of the D-dopachrome tautomerase assay, MIF may be developed as a potential marker of male infertility in Sri Lanka.
