following in-vitro fertilization and embryo transfer in a patient with a p
revious ipsilateral (left) salpingo-oophorectomy. The previous surgery was
for endometriosis. We discuss the possible contribution of the embryo trans
fer technique, limitations of preventive measures and importance of transva
ginal ultrasound in establishing the diagnosis.
