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 …

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 …

BACKGROUND The influence of elevated serum progesterone levels during in vitro
fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles on pregnancy rates is a matter …

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

BACKGROUND A successful oocyte cryopreservation programme is of utmost importance
where a limited number of oocytes can be inseminated per cycle, to overcome legal and …

Purpose The synchronized development of a viable embryo and a receptive endometrium is
critical for successful implantation to take place. The aim of this paper is to review current …

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 …

Recent dramatic increases in success rates with frozen–thawed embryo transfer (FET) are
encouraging, as are numerous findings of several reduced risks with FET when compared …
