In the last decade, the number of pregnancies after frozen embryo transfer (frozen-ET) has increased substantially, 1 due to improved cryopreservation methods that facilitate single embryo transfer. If there are surplus embryos, these are frozen and can be thawed and transferred in subsequent cycles. 1 The conventional approach in ART involves either in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), followed by fresh embryo transfer (fresh-ET). ![]() Worldwide, use of assisted reproductive technology (ART) has increased, and today, children born after ART constitute up to 7% of birth cohorts in several Western countries. The high risk of hypertensive disorders following frozen embryo transfer raises concerns about the increasingly popular elective freezing of all embryos. ![]() Customer Service and Ordering InformationĬlinical/Pathophysiological Implications?.Stroke: Vascular and Interventional Neurology.Journal of the American Heart Association (JAHA).Circ: Cardiovascular Quality & Outcomes.Arteriosclerosis, Thrombosis, and Vascular Biology (ATVB). ![]()
