Aim To assess the birthweight of neonates conceived after fresh and frozen embryo transfers
(FET) and, if different, to investigate whether estradiol levels during the late follicular phase …

Background Previous studies have investigated the effect of maternal age on assisted
reproductive technology success rates. However, little is known about the relationship …

Research question Previous studies have demonstrated a negative relationship between
peak oestradiol and low birthweight in IVF. However, it is hard to distinguish which aspect …

STUDY QUESTION Is supraphysiologic estradiol (E2) an independent predictor of low birth
weight (LBW) in singletons born after fresh IVF-embryo transfer (ET) cycles? SUMMARY …

High oestradiol concentrations may be detrimental to the success of in-vitro fertilization (IVF)
treatment. A total of 1122 women aged< 40 years who were undergoing their first IVF cycle …

Objective To explore whether the duration of estrogen treatment before progesterone
application affects neonatal and perinatal outcomes in artificial frozen embryo transfer (FET) …

Introduction Perinatal risks after frozen embro transfer (FET) have been reassuring but some
authors suggest that birthweights are higher after FET than after fresh embryo transfer (ET) …

Abstract Research Question Is there an association between the weight of women and the
gender of offspring generated from fresh and frozen/thawed embryo transfer (FET) cycles …

STUDY QUESTION Do the length of follicular phase estradiol exposure and the total length
of the follicular phase affect pregnancy and live birth outcomes in natural frozen embryo …

Background The aim of this paper was to determine the effect of supraphysiologic serum
estradiol (E2) level on oocyte and embryo development during IVF cycles. Methods This is a …
