Frozen-thawed embryo transfer (FET) has been a viable alternative to fresh embryo transfer
in recent years because of the improvement in vitrification methods. Laboratory-based …

This study investigates the effect of GnRHa pretreatment on pregnancy outcomes in artificial
endometrial preparation for frozen–thawed embryo transfer (AC-FET) cycles. A systematic …

Background: Unsubstantiated concerns have been raised on the potential correlation
between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and …

Objective This study aimed to examine the efficacy of HRT with gonadotropin-releasing
hormone agonist (GnRH-a) pre-treatment in women with male-factor infertility who …

Background: Surgery in elder patients with intermural fibroids delays pregnancy, and GnRH-

Background Gonadotrophin-releasing hormone (GnRH) administration significantly
decreases the pregnancy rate of recipient ewes after embryo transfer, possibly because …

Abstract Background GnRH agonist (GnRHa) has been reported to have direct effects and
functional roles in the endometrium and embryos. Several meta-analyses have shown that …

Background The cumulative live birth rate (CLBR) has been regarded as a key measure of
in vitro fertilization (IVF) success after a complete treatment cycle. Women undergoing IVF …

Despite that gonadotropin-releasing hormone (GnRH) agonist pretreatment has been widely
used before programmed frozen-thawed transfer (FET), its impact on live birth rates in …

Background The accurate prediction of pregnancy outcomes in in vitro fertilization (IVF)
cycles is crucial. While several studies have been conducted on the predictive power of …
