The impact of fetal gender on prematurity in dichorionic twin gestations after in vitro fertilization
BACKGROUND Impact of fetal gender on prematurity has been primarily investigated in singleton pregnancies. In an attempt to understand better how fetal gender may affect gestational length in twin gestations after in vitro fertilization, same-sex twins and opposite twins were compared for pregnancy duration. METHODS This study evaluated 113 women at ages 20 to 39 years with consecutive dichor...
متن کاملI-5: Cancellation of Fresh Embryo Transfer: A Future Perspective
Controlled ovarian hyperstimulation (COH) affects adversely implantation following in vitro fertilization and embryo transfer. COH with gonadotropins alters endometrial receptivity and luteal function. In addition periovulatory endometrial characteristics in stimulated cycles are considerably different compared with the natural cycles, and periovulatory secretory transformation is consistently ...

متن کاملPerinatal Risks Associated with Early Vanishing Twin Syndrome following Transfer of Cleavage- or Blastocyst-Stage Embryos
Objective. To investigate whether the perinatal risks associated with early vanishing twin (VT) syndrome differ between cleavage- or blastocyst-stage embryo transfers (ET) in fresh in vitro fertilization (IVF) cycles. Methods. Retrospective, single-center, cohort study of IVF cycles with fresh cleavage- or blastocyst-stage ETs resulting in a live singleton birth. The incidence of preterm birth ...
متن کاملDoes a Vanishing Twin Affect Perinatal Outcome?
Background: The impact of vanishing twin (VT) syndrome on obstetric outcome is currently unknown. The aim of this study was to compare obstetric and neonatal outcomes of VT with singleton and twin deliveries after assisted reproduction and to evaluate the impact of VT on pregnancy outcome. Methods: We analyzed 130 births at our hospital between January 2000 and February 2012 that resulted from ...
