ABSTRACT BACKGROUND Elective freezing of all good quality embryos and transfer in
subsequent cycles, ie elective frozen embryo transfer (eFET), has recently increased …

Implantation is a critical step in human reproduction. The success of this step is dependent
on a competent blastocyst, receptive endometrium, and successful cross talk between the …

Background The transfer of fresh embryos is generally preferred over the transfer of frozen
embryos for in vitro fertilization (IVF), but some evidence suggests that frozen-embryo …

OBJECTIVE: To examine the available evidence to assess if cryopreservation of all embryos
and subsequent frozen embryo transfer (FET) results in better outcomes compared with …

OBJECTIVE: To compare success rates between fresh ETs after ovarian stimulation and
frozen–thawed ETs (FET) after artificial endometrial preparation, to compare endometrial …

OBJECTIVE: To create a genomic tool composed of a customized microarray and a
bioinformatic predictor for endometrial dating and to detect pathologies of endometrial …

BACKGROUND Improvements in vitrification now make frozen embryo transfers (FETs) a
viable alternative to fresh embryo transfer, with reports from observational studies and …

BACKGROUND Elevated serum progesterone levels at the end of the follicular phase in
controlled ovarian stimulation (COS) leads to a poorer ongoing pregnancy rate in IVF cycles …

To allow selection of embryos for transfer after in vitro fertilization, ovarian stimulation is
usually carried out with exogenous gonadotropins. To compensate for changes induced by …

Human implantation is a complex process requiring synchrony between a healthy embryo
and a functionally competent or receptive endometrium. Diagnosis of endometrial receptivity …
