[Research in the relationship between Chlamydia and ureaplasma and infertility]

Samples taken from cervix and male urethra of 768 infertilitas patients were studied, and samples taken from 226 normal fertile males and females served as control. The fluorescent monoclonal antibody technique and cell culture method were used for Chlamydia trachomatis (Ct) and microbiological culture method was used for Ureaplasma urealyticum (Uu) detection. The positive rates of Ct and Uu infections were 28.64% (220/768) and 36.59% (281/768) in infertilitas group, 5.2% (14/266) and 14.28% (38/266) in control group respectively. There was significant difference between the 2 groups (P < 0.01). The results suggest that infection with Ct or Uu is one of the factors causing infertility.
