Objective: To present a rare infectious complication related to transcervical ET, without prior transvaginal puncture.
Design: Case report.
Setting: Hadassah University Hospital, IVF-ET unit.
Patient: One patient undergoing cryopreserved-thawed ET.
Interventions: Artificial preparation of the endometrium with E2 and P, followed by transcervical intrauterine cryopreserved-thawed embryo transfer.
Results: After ET, severe pelvic inflammatory disease (PID) with ruptured tubo-ovarian abscess was diagnosed and treated.
Conclusions: Severe PID including tubo-ovarian abscess formation should be considered a potential complication after ET, even without transvaginal oocyte aspiration.
