Embryo transfer can be performed in either uterine horn. Two successive pregnancies in a patient with uterus didelphys: a case report.

BACKGROUND: Uterus didelphys results from a failure in Mullerian duct fusion and may be associated with complete or partial vaginal septa. Most cases of uterus didelphys are discovered incidentally during the workup of infertility or recurrent miscarriage. The incidence of uterus didelphys has been reported to be 0.2% in the infertile population. CASE PRESENTATION: A 35-year-old white Arab woman, gravida 0, parity 0, with a history of primary infertility of 8 years (a well-known male factor) presented to our infertility center. She was diagnosed as having uterus didelphys with severe male factor. The patient had three previous failed in vitro fertilization/intracytoplasmic sperm injection cycles outside our center. This is a case report of an infertile woman with uterus didelphys who conceived twice following single embryo transfer in both uterine horns successively. After the first successful pregnancy in the left uterine horn, the initial decision was to transfer the embryo to the same horn (left) because of the previous successful transfer. The very deep and long vagina forced us to reach one of the cervices, in which the embryo was placed in the right uterine horn, followed by the second successful pregnancy in the other, smaller horn. The patient gave her informed consent, both verbal and written, to use her information and images for medical publication. CONCLUSION: Pregnancy is possible in women with uterus didelphys using single embryo transfer in in vitro fertilization/intracytoplasmic sperm injection cycles. It is recommended that both horns be given a chance.
