Background The aim of this study was to investigate the effect of body mass index (BMI) on the outcome of in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) cycles in non polycystic ovary syndrome (PCOs) women. MaterialsAndMethods In this cross sectional study, 287 infertile non PCOs women referred to Royan institute, Tehran, Iran between 2002 and 2003 were enrolled. Patients...

BACKGROUND Embryo transfer, a crucial step for achieving pregnancy after in vitro fertilization, is an operator-dependent technique but the number of procedures required for a trainee to reach proficiency is unknown. We set out to evaluate the learning curve (LC) of embryo transfer using a specifically designed statistical tool. METHODS The first embryo transfers performed by five trainees we...

The value of measuring the endometrial thickness and studying the endometrial receptivity in the context of assisted conception remains a contentious issue. A prospective analysis was carried out to determine the effect of endometrial thickness on IVF - embryo transfer/ICSI outcome in dedicated Assisted Reproductive Technology (ART) units in Abuja and Rivers State, Nigeria. Two hundred and fift...

BACKGROUND As discontinuation in in vitro fertilization (IVF) programs has been associated with a poor prognosis, one hypothesis is that some couple-specific predictive factors in IVF may be shared with opposite effect by both success (i.e. live birth) and treatment discontinuation processes. Our objective was to perform a joint analysis of these two processes to examine the hypothesis of a lin...

clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. objective: to investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors wh...

Conceiving a child by way of embryo selection and tissue matching to benefit a sick sibling is generally justified on the grounds that as well as the potential to save the sick child, there is a benefit for the new baby. The new baby is selected so he or she will not have the disease suffered by the first child. It is not possible, however, to select against conditions for which there is no tes...

Background The aim of this study was to compare prenatal outcome of intra cytoplasmic sperm injection (ICSI) pregnancies with pregnancies obtained through in vitro fertilization (IVF). MaterialsAndMethods Retrospectively 532 pregnancies of ART cycles were assessed during 1999-2000. The main outcome measured including abortions, ectopic pregnancies, prematurity, low birth weight, cesarean sectio...
