Fetal outcome of triplets in a Turner mosaic.

Pregnancies are now being reported resulting from fertilization of donor oocytes in women with ovarian failure. A case of triplets in a Turner mosaic is reported herein following transfers of embryos resulting from donor oocytes. She had previously demonstrated a normal sized uterine cavity by hysterosalpingography. The opinion from our group was that she should consider selective reduction but a perinatology consult thought she should have a favorable outcome. Her pregnancy was complicated by polyhydramnios, pre-term labor, and eventual fetal demise at 25 and 27 weeks of all three fetuses. Natural pregnancies in patients with gonadal dysgenesis have been reported in at least 138 patients. Many aborted or had stillbirths and this high rate of fetal mortality has been ascribed to chromosomal abnormalities. The continued use of donor oocytes will provide data to evaluate whether there will continue to be a higher spontaneous abortion rate and complications in second and third trimesters in Turner's pregnancies even in single pregnancies. The outcome of this case can at least be provided to future gonadal dysgenesis patients with triplets to help them in their decision as to whether or not to have selective reduction.
