Primary ovarian pregnancy after in vitro fertilization and embryo transfer: report of seven cases

Abstract

We have reported seven cases of ovarian pregnancy from among 116 EPs and 2,745 clinical pregnancies achieved after IVF and ET at Bourn Hall Clinic. All were associated with lower than normal serial levels of serum hCG and P. Transvaginal US scanning correctly made the diagnosis of ectopic gestation in all cases, and in five, ovarian pregnancy was suspected on the scan findings. Three patients were asymptomatic, whereas four complained of lower abdominal pain with or without vaginal discharge or bleeding. All patients were treated conservatively; four had ovarian wedge resection and three ovarian cystectomy.
