[Study on infertility caused by infections of Chlamydia trachomatis and ureaplasma urealyticum].

OBJECTIVE

To explore the effects of chlamydia trachomatis (CT) and ureaplasma urealyticum (UU) infections on male and female infertility.

METHODS

Samples from cervical canal or male urethra of 1198 infertile patients (599 couples) were studied and from 167 normal fertile men and women served as control. The fluorescent monoclonal antibody technique and the culture method were used for CT and UU assays respectively.

RESULTS

The positive rates of CT and UU infections in infertile group were 25.5% (306/1 198) and 35.9% (167/1 198) respectively, while 6.6% (11/167) and 15.6% (26/167) in the control group respectively. There were significant differences between the 2 groups (P < 0.01). After treatment of positive patients, the pregnancy rates were higher in those patients became negative than that in patients remained positive (P < 0.01).

CONCLUSION

The CT and UU infections were one of the factors causing infertility.
