AIM: To study the influence of Ureaplasma u re alyticum (Uu) on the functional integrity of sperm membrane and the seminal para meters by computer-assisted semen analysis (CASA). METHODS: By C ASA and the Kit, 160 cases (22~38 years old, 2 a after marriage) of infertility were tested for Uu, the functional integrity of sperm membrane and seminal param eters. RESULTS: The positive rate of Uu was 36 3 %. The swellin g sperms of Type B-E and Type E in the positive group were 0 44 and 0.11 respec tively, and that in the negative group were 0.68 and 0 17 respectively. There w as a significant difference in the functional integrity of sperm membrane betwee n positive group infected by Uu in semen and negative group (P0 01). The parameters by CASA in the positive group and negative group h ad a remarkable difference except those of sperm concentration, motion degree, s eminal volume and linear. CONCLUSION: Ureaplasma urealyticum ca n notably lower the functional integrity of sperm membrane and motile-sperm conc entration, sperm vitality and velocity of motion and change the motile patterns. The present result shows that infection with Uu is one of the important factors of infertility.
