Unilateral ovarian agenesis: report of three cases and review of the literature.

INTRODUCTION

Unilateral ovarian agenesis is a rare event and only a few case have been reported.

CASE REPORT

We present three additional cases, where patients presented with diffuse lower abdominal pain. During laparoscopy, an unilateral ovarian agenesis was observed in the three cases.

DISCUSSION

There are two possible explanations of a unilateral ovarian absence, involving an asymptomatic adnexal torsion or congenital absence. Unknown environmental factors or genetic predisposition could contribute to this kind of anomaly.
