Ruptured tubo-ovarian abscess complicating transcervical cryopreserved embryo transfer

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 E(2) and P, followed by transcervical intrauterine cryopreserved-thawed embryo transfer. Results: After ET, severe pelvic inflammatory disease (PID) with ruptured tube-ovarian abscess was diagnosed and treated. Conclusions: Severe PID including tube-ovarian abscess formation should be considered a potential complication after ET, even without transvaginal oocyte aspiration.
