Abstract

In this study, semen samples from fertile and unexplained infertile men were explored for relationships between seminal plasma immunosuppressive factors (SPIFs), semen pH, liquefaction duration and infection of ureaplasma urealyticum (Uu). SPIFs activity was measured by way of counteracting complement. PH was detected by exact pH test paper. Liquefaction duration was observed at 37 degrees C. The results showed that Uu infection ratios of semen samples with abnormal SPIFs, pH or liquefaction duration were markedly higher than those of normal semen samples. It is suggested that Uu infection decreases the level of SPIFs, changes the pH in semen and prolongs the semen liquefaction so as to cause spermatic quality decline. The enhancement of SPIFs level may change the male body against Uu infection.
