Pregnancy outcome after multifetal pregnancy reduction to twins compared with spontaneously conceived twins.
Multifetal pregnancy reduction (MFPR) appears to be an efficacious method for improving the perinatal outcome of 'high order' multifetal gestations. The present study was undertaken to evaluate pregnancy outcomes after MFPR to twins in comparison with spontaneously conceived twins. In all, 10 patients with quadruplet gestation (group 1) and 30 patients with triplet gestation (group 2), who unde...

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...

OBJECTIVE To compare the outcomes of twin pregnancies conceived by artificial reproductive techniques (ART) with those of spontaneous conception. STUDY DESIGN In this multicenter prospective trial, comparisons were made between methods of conception in twin pregnancies, for maternal and perinatal outcomes. RESULTS Of 1001 twin pairs, 763/1001 (72.7%) were spontaneously conceived and 238/100...
متن کاملPregnancy outcome among twins conceived after subfertility treatment compared with natural twins: A population-based study.
Pregnancy outcome and characteristics of women who conceive following subfertility treatment remains a subject of great interest. We analyzed these variables among 199 women who delivered a registerable twin birth compared with 1773 women who delivered a naturally conceived twin birth in a population-based obstetric cohort drawn from around Oxford, England. Treatment was restricted to conceptio...
متن کاملConfined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously
Traditionally, monochorionicity has been regarded as synonymous with monozygosity. However, several recent cases of monochorionic dizygotic twins have shown that monochorionic twins can be dizygous. We report a rare case of monochorionic diamnionic, gender-discordant twins who were conceived spontaneously. Initially, a monochorionic placenta was diagnosed by ultrasonography at 8 weeks of gestat...
