[Endometrial Chlamydia infection in women with habitual abortion]

Endometrial, endocervical, and urethral specimens were obtained from 16 nonpregnant women with a history of habitual abortions. Chlamydia were isolated from the endometria of 4 women, but only in one case chlamydial intracytoplasmic incorporations in endometrial cells were detectable by the Romanovsky Giemza staining. Endometrial Chlamydia infection was diagnosed in 5 of the 16 patients. No Chlamydia were isolated from the cervix uteri or urethra of 2 patients with endometrial involvement. The study has demonstrated that eradication of intrauterine chlamydial infection before pregnancy improves the efficacy of treatment of habitual abortions. It is possible that asymptomatic chlamydial endometrial infection is injurious for the placenta.
