The relation between Chlamydia trachomatis infection and subsequent tubal damage is widely recognized. As such, C. trachomatis antibody (CAT) testing can be used to triage women for immediate tubal testing with hysterosalpingography (HSG) or laparoscopy. However, once invasive tubal testing has ruled out tubal pathology, CAT serology status is ignored, as its clinical significance is currently unknown. This study aimed to determine whether positive CAT serology is associated with lower spontaneous pregnancy rates in women in whom HSG and/or diagnostic laparoscopy showed no visible tubal pathology.
