PURPOSE: In this first of two companion papers, we critically review the evidence recently published in the primary literature, which addresses adverse maternal and neonatal pregnancy outcomes associated with programmed embryo transfer cycl…

PURPOSE: In the first of two companion papers, we comprehensively reviewed the recent evidence in the primary literature, which addressed the increased prevalence of hypertensive disorders of pregnancy, late-onset or term preeclampsia, feta…

Background: Nowadays, frozen-thawed embryo transfer (FET) cycles represent a high proportion of fertility treatments worldwide. Recent studies suggest differences in pregnancy outcomes depending on the FET treatment protocol used. The reaso…

PURPOSE: The objective of this retrospective cohort study was to compare fetal growth during the second and third trimesters for ovulation induction with intrauterine insemination (IUI), fresh embryo transfer (ET), frozen embryo transfer (F…

Although most pregnancies after assisted reproduction are associated with a favorable outcome for the mother and infant, reports of abnormal vascular adaptation in early pregnancy and emerging maternal and perinatal pathology warrant furthe…

Identifying modifiable factors that contribute to preeclampsia risk associated with assisted reproduction can improve maternal health. Vascular dysfunction predates clinical presentation of preeclampsia. Therefore, we examined if a nonphysi…

ObjectiveTo assess whether pregnancies achieved with trophectoderm biopsy for preimplantation genetic testing (PGT) have different risks of adverse obstetric and neonatal outcomes compared with pregnancies achieved with IVF without biopsy.D…

PURPOSE: The aim of this study was to determine whether first trimester ultrasound measurements of crown rump length (CRL) and gestational sac diameter (GSD) differ depending on the method of conception among infertile women. METHOD: Infer…

PURPOSE: Animal and human studies suggest that vitamin D regulates functions of the reproductive system. Vitamin D deficiency is prevalent in women of reproductive age. Vitamin D status has been associated with in vitro fertilisation outcom…

The past decade has seen a renewed interest in ‘the sunshine vitamin’ vitamin D, because new evidence demonstrates benefits beyond bone health and an increase in the prevalence of vitamin D deficiency in the general population and in popula…

The past decade has seen a renewed interest in ‘the sunshine vitamin’ vitamin D, because new evidence demonstrates benefits beyond bone health and an increase in the prevalence of vitamin D deficiency in the general population and in popula…

In the past few years a growing interest in vitamin D can be observed in the lay and biomedical literature due to findings demonstrating a low vitamin D status in the population. In addition to its importance for the regulation of calcium a…
