The incidence of hypertensive disorders of pregnancy following sperm donation in IVF: An Australian state-wide retrospective cohort study

Abstract

STUDY QUESTION: Does IVF using donor sperm increase the risk of hypertensive disorders of pregnancy and fetal growth restriction (FGR)? SUMMARY ANSWER: IVF conceptions arising from sperm donation are not associated with an increased risk of hypertensive disorders of pregnancy or FGR.
