Infertility is one of the major issues in society and its incidence is estimated to be almost 10-15%.. Chlamydia is an important cause of sexually transmitted diseases leading to infertility.

This study was designed to determine the frequency of anti-Chlamydia trachomatis (anti-C. trachomatis) antibodies in infertile women at Alzahra hospital, Tabriz, Iran.

The frequency of anti-C. trachomatis IgG in pregnant and infertile women was 18% and 35.88%, respectively. The frequency of anti- C. trachomatis IgM in pregnant and infertile women was 2% and 5.44%.Our results showed the significant high rate of anti-Chlamydia trachomatis IgG (p=0.035), IgM (p=0.004) (p0.05).

According to the high frequency of antibody anti-C. trachomatis among infertile women in competition to the control group, evaluation and treatment of Chlamydia infections is necessary in these patients.
