OBJECTIVE: To assess fetal and maternal outcomes of pregnancies in women with Turner syndrome (TS).
DESIGN: Retrospective case series.
SETTING: Clinical research center.
PATIENT(S): 276 adults with cytogenetically proven TS participating in an intramural natural history protocol.
MAIN OUTCOME MEASURE(S): Menstrual and obstetric histories, 50-cell karyotypes, and cardiovascular evaluation including aortic diameter measurements.
RESULT(S): Our cohort included five women with spontaneous pregnancies and five with pregnancies using assisted reproduction (ART). All five women with spontaneous pregnancies had spontaneous puberty, despite 45,X in ≥90% of their 50-cell karyotype. Participants had a total of 13 pregnancies and 14 live births. One child had cerebral palsy; the others were chromosomally and developmentally normal. Delivery was by cesarean section in four out of seven spontaneous and six out of six ART-related pregnancies. One mother experienced preeclampsia in an ART-related twin pregnancy that required a preterm delivery; she has marked but stable aortic dilation years later.
CONCLUSION(S): Approximately 2% of our study cohort experienced spontaneous pregnancies despite high-grade X monosomy, and a similar number achieved pregnancy via oocyte donation and ART. The potential for life-threatening cardiovascular complications warrants comprehensive screening before conception or single-embryo transfer, and caution regarding unintentional pregnancies for TS women.
