Simultaneous bilateral tubal pregnancy after intracytoplasmic sperm injection.

Since the advent of assisted reproductive technology, the concern about ectopic implantation of embryos has increased dramatically. Simultaneous bilateral tubal pregnancy is the least common type of ectopic implantation of two embryos. In this report we present the first case of simultaneous bilateral tubal pregnancy after intracytoplasmic sperm injection (ICSI) and embryo transfer treatment. The present case had no risk factor for ectopic pregnancy. Therefore, for early diagnosis and management of such cases, close clinical follow-up and routine ultrasonography following ICSI are necessary.
