Unsuspected chronic pelvic inflammatory disease in the infertile female.

Diagnostic laparoscopy performed during an infertility evaluation identified 80 patients with hydrosalpinges (12% of all laparoscopic examinations performed for infertility). Despite these findings, only 20 (25%) of these patients reported a prior episode of acute pelvic inflammatory disease (PID), and only 18 (22.5%) had complaints of pelvic pain. Compared with a matched group of infertility patients with no endoscopic evidence of prior pelvic infection, those patients with hydrosalpinges were more likely to have used an intrauterine device and were less likely to have used an oral contraceptive. Since "silent" PID is a potential cause of infertility, endoscopic visualization of the female reproductive organs should be considered during the infertility evaluation. Moreover, in view of its insidious nature, the diagnosis of PID should be considered in a young sexually active patient with gynecologic complaints.
