Haemoperitoneum due to ovarian rupture after oocyte retrieval procedure.

Transvaginal ultrasound-guided oocyte retrieval is the gold-standard technique for oocyte retrieval that has few associated procedural and post-procedural complications. Rarely, severe complications can occur including haemoperitoneum, for which the incidence reported in the literature is approximately 0.08-0.22%. In this report, we present the case of a nulliparous woman in her late 30s who presented to the hospital with severe abdominal pain following transvaginal ultrasound-guided oocyte retrieval and was found to have extensive haemoperitoneum attributed to ovarian rupture.
