Kuiper D, et al. - Researchers sought to assess whether the in vitro procedure, ovarian hyperstimulation or a combination of these two are associated with blood pressure (BP) of 9-year-old IVF children born to subfertile couples. Findings revealed no association of ovarian hyperstimulation and in vitro procedures with cardiovascular health in 9-year-old. Yet, BP percentiles of the three groups were higher than the expected 50th percentile. This suggested relatively a higher BP in children of subfertile couples than naturally conceived children.
