[Twin pregnancy after oocyte donation in a woman with Turner syndrome]

It is extremely rare for pregnancy to occur spontaneously in patients with Turner's syndrome, and if it happens this will have an increased risk of fetal wastage and congenital malformations in the new born, specially of the sexual chromosome. Oocyte donation is at present the technique of choice to release the reproductive wishes of these women. We present a case of a woman with Turner's syndrome, with a 45, X0 karyotype, to whom ovum donation and intrauterine embryo transfer were performed, obtaining a twin pregnancy without complications. A cesarean section was made at term, obtaining two healthy new born infants.
