Summary, in English

The rate of spontaneous pregnancies in women with Turner syndrome (TS) is low (2% to 5%). Oocyte donation is an option for these women and enables many to become pregnant. Some investigators question the use of pregnancy induction in TS because of the high risk for aortic dissection or other serious cardiac events. A cardiac evaluation is recommended before pregnancy is planned in TS. Among patients with TS who use their own oocytes to become pregnant, 45% suffered a miscarriage. The aim of this study was to assess pregnancy rate and outcome in a population of Swedish women with spontaneous pregnancies or who were induced using donated oocytes. Cytogenetic karyotype also was examined; mosaicism was defined as the presence of more than 5% 46, XX cells. The study subjects were 482 women with TS who had participated in a voluntary screening program conducted at Swedish Turner Centers. Among the 482 women with TS, 57 (12%) had pregnancies, including spontaneous pregnancies. The live-born rate was 67 of 124 (54%). The patient's own oocytes were used in 27 (47%) of the pregnancies and oocyte donation in 30 (53%) of pregnancies. Spontaneous pregnancies occurred in 23 of 57 women (40%) with TS. Most pregnancies using the patient's own oocytes occurred in those with 45, X/46, XX mosaic karyotype. The miscarriage rate was 26% after oocyte donation and 45% with the use of the patient's own oocytes. Five liveborns (7%) had birth defects or a serious illness; 4 of these were born after spontaneous pregnancies. Only 1 live-born had coarctation of the aorta.
