BACKGROUND Fertility expectations for patients with Turner's syndrome (TS) have clearly changed in the last three decades. However, medical risks during pregnancy are supposed to be highly increased. The aim of the study was to assess clinical outcome and obstetrical complications in a series of patients with TS in an oocyte donor programme. METHODS A retrospective study was carried out on 24 women with TS seeking a pregnancy in the Fertility Clinic of the Erasme Hospital from 1992 up until March 2011. RESULTS Twenty-three patients with TS were included in an oocyte donation cycle. Forty-nine oocyte donation cycles were performed, which led to 45 fresh and 10 frozen-thawed embryo transfers. Altogether, 18 pregnancies were obtained, 10 deliveries (9 singletons and 1 pair of twins), 3 miscarriages and 5 biochemical pregnancies. The clinical pregnancy rate per transfer was 24.4% in fresh cycles and 20% in frozen replacement cycles. Complications of pregnancy occurred in 5 of 10 pregnancies (50%), which led to three premature deliveries because of pregnancy-induced hypertensive disorders. The mean birthweight (g) (±SD) for singletons and twins was 2728 ± 577 and 2335 ± 318, respectively. Four babies were below the 10th percentile. No cardiac complications were observed in any of the pregnant women. CONCLUSIONS Pregnancy rates after oocyte donation in patients with TS are comparable with those previously published but a high risk of pregnancy hypertensive disorders and a high risk of low birthweight can be highlighted from our study. Strict inclusion criteria and single embryo transfer are necessary to minimize complications during pregnancy in this high-risk group.
