Pregnancy in heterotopic fallopian tube and unilateral ovarian hyperstimulation.

A rare genital anomaly is described, consisting of a right hemiuterus with a rudimentary horn and a remotely located left fallopian tube, totally disconnected from the pelvic genitalia, and ruptured by an ectopic pregnancy. An associated finding was a unilateral hyperstimulated ovary (post HMG-HCG therapy), confined to an accessory ovary on the left. The case is presented in detail, and the unusual anatomical and functional features are discussed.
