Abstract:
UNLABELLEDTo investigate the relationship between Ureaplasma urealyticum (UU) infection and semen quality.
METHODSFrom 2001 to 2003, 346 eligible patients aged 20-45 years were invited from two hospitals in Shanghai, China, to participate in an investigation which included questionnaires about general and reproductive health, an external genital tract examination, UU culture and semen analysis. Multiple linear regression models were used to examine whether UU had a significant effect on semen quality after adjustment for confounding factors.
RESULTSFindings suggested that UU infection was associated with higher semen viscosity and lower semen pH value. Sperm concentration was lower in UU positive subjects than that in UU negative subjects (54.04 X 10(6)/mL vs.70.58 X 10(6)/mL). However, UU did not significantly affect other semen quality indexes.
CONCLUSIONUU infection of the male genital tract could negatively influence semen quality.
