Selenium status of idiopathic infertile nigerian males

Selenium concentration in the sera and seminal plasma of 60 infertile males (40 oligospermia and 20 azoospermia) and 40 males with proven evidence of fertility (normospermia; control group) were estimated using atomic absorption spectrophotometry. Results were correlated with spermatogram and hormonal levels in order to determine their relationship and significance in male infertility. The mean serum concentrations of selenium was found to be significantly increased in oligospermic compared to azoospermic subjects and controls (p<0.01), whereas the seminal plasma level was significantly higher in azoospermic compared to oligospermic subjects and controls (p<0.001). Thus, the ratio of serum selenium to seminal plasma selenium was 1∶1 in controls, 4∶1 in oligospermia, and 1∶2 in azoospermic subject.
