Objective Advancements in medical technology have significantly increased the possibility of successful infertility treatment. Medical interventions in the initial process of pregnancy that intend to increase the chances of pregnancy create the risk of multifetal pregnancies for both mothers and fetuses. Physicians attempt to reduce the numbers of fetuses in order to decrease this risk and guar...

During Assisted Reproductive Technology (ART) procedures, the transfer of a single embryo dramatically reduces the rate of multiple pregnancy. Proper information, therefore, should be delivered to patients before embryo transfer. In many countries, regulations limit, according to age of the patient, the number of embryos to be transferred. Selective fetal reduction should not be considered as a...

During the recent decades with increasing the use of assisted reproductive techniques including IVF, IUI and ovulation induction, the rate of multiple pregnancies has been increased worldwide. More than 30% of ART pregnancies are twins or higher-order multiple gestations (triplets or greater) a frequency 15- to 20-fold greater than with spontaneous conceptions. Because of the high cost of treat...

OBJECTIVE The purpose of this study was to evaluate the effects of maternal-fetal genetic histocompatibility and the association of that condition with maternal undernutrition regarding fetal growth and litter size. STUDY DESIGN Fetuses that were either syngeneic or allogeneic with the mothers were bred, using mice of well-defined syngeneic strains (A/J and Balb/c). Pregnant mice were fed usi...

INTRODUCTION Triplet and higher-order multiple pregnancies are well known to be associated with increased adverse outcomes. This study reviewed the perinatal outcomes in women with a triplet pregnancy who underwent fetal reduction versus expectant management at a university hospital in Hong Kong. METHODS This was a retrospective review of triplet pregnancies at Prince of Wales Hospital in Hon...
