This case study reports an ovarian ectopic pregnancy following frozen embryo transfer in a patient with subfertility and fibroids, noting that endometriosis is a known risk factor for such ectopic implantation.

This case report describes a patient with male factor subfertility who developed an ovarian ectopic pregnancy following frozen embryo transfer via intracytoplasmic sperm injection. Although the patient had multiple small fibroids and presented with fluctuating beta-hCG levels, laparoscopic surgery confirmed the diagnosis of ovarian ectopic gestation with normal fallopian tubes. The authors note that while pelvic inflammatory disease and endometriosis are known risk factors for altering tubal patency and causing ectopic pregnancy, fibroids are not yet recognized as such, suggesting this case involved retrograde embryo migration. This paper is centrally about endometriosis — specifically, it cites endometriosis as a known risk factor for ectopic pregnancy in its introduction to contextualize the pathophysiology of the reported ovarian ectopic gestation.

Abstract

Assisted reproduction technique (ART) is a known risk factor for ectopic pregnancy (EP). Ovarian ectopic pregnancy (OEP) is a rare but well-known variant of EP, which carries diagnostic challenges & is mostly diagnosed intraoperatively. Fibroid is a common medical problem, but it is not yet a recognised risk factor for OEP. Risk factors as pelvic inflammatory disease, endometriosis or fibroids can alter fallopian tube patency results in EP. In this case study the embryo implantation occurs in the ovaries with retrograde embryo migration from the uterine cavity to the peritoneum. We present an OEP with male factor subfertility that went for frozen embryo transfer. The woman had multiple small fibroids referred to the tertiary centre for fluctuation in β-hCG level and suspicion of cornual pregnancy. However, the patient was asymptomatic & haemodynamically stable. Initial diagnosis of EP with viable fetus necessitate laparoscopic interference revealed left sided OEP with normal left fallopian tube (FT). The right ovary and FT looked normal. Surgical interference with partial oophorectomy was done and the histopathological report confirms the diagnosis of OEP. The following embryo transfer after 3 months ended by viable intrauterine pregnancy.
