Maternal hyperglycemia in singleton pregnancies conceived by IVF may be modified by first-trimester BMI
STUDY QUESTION Does IVF independently increase the risk of gestational diabetes mellitus (GDM) and is this increase in risk modified by maternal body mass index? SUMMARY ANSWER IVF appears to be an independent risk factor for GDM and elevated blood glucose levels in overweight women (BMI > 25 kg/m2). WHAT IS KNOWN ALREADY IVF has been associated with increased risk of GDM, but most previous...
متن کاملP-166: Obstetric and Neonatal Outcomes of Twin Pregnancies Conceived by Assisted Reproductive Techniques Compared with Natural Conceived Twins: A Prospective Follow-Up Study
Background: Comparison of obstetric and neonatal outcomes of twin pregnancies conceived by assisted reproduction technology (ART) with those of spontaneously conceived (SC). Materials and Methods: In this prospective cohort study, all dichorionic twin pregnancies following fresh IVF/ intra-cytoplasmic sperm injection (ICSI) or ICSI cycles (n=320) and (SC) (n=170) in nulliparous women in Royan I...
متن کاملCell-free fetal DNA levels in pregnancies conceived by IVF.
BACKGROUND Increased second-trimester levels of maternal serum HCG in IVF conceptions lead to an increased false-positive rate in Down syndrome screening. Increased levels of cell-free fetal DNA (cffDNA) in maternal plasma have been correlated with increased HCG levels. Our aim was to determine whether cffDNA levels are elevated in IVF pregnancies compared with natural pregnancies. METHODS Si...
متن کاملDo placentae of term singleton pregnancies obtained by assisted reproductive technologies differ from those of spontaneously conceived pregnancies?
The study was conducted to investigate the association of placental morphological and histopathological features with term, singleton pregnancies obtained by assisted reproductive technologies (ART). The study group comprised 45 consecutive women with a singleton pregnancy, obtained by ART, who delivered at term. For each subject in the study group, the consecutive, matched-for-age-and-parity w...
متن کاملDifferential immunoregulation in successful oocyte donation pregnancies compared with naturally conceived pregnancies.
In oocyte donation (OD) pregnancies, there is a higher level of antigenic dissimilarity between mother and fetus compared with naturally conceived (NC) pregnancies. We hypothesize that a higher degree and/or a different type of immunoregulation is necessary to maintain an uncomplicated OD pregnancy. Different immunological aspects of successful OD pregnancies (n=28) were compared with those of ...
