BACKGROUND Polycystic ovary syndrome (PCOS) is the most common cause of
anovulatory infertility. An endometrial component has been suggested to contribute to …

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

Background Elective single embryo transfer (eSET) has been increasingly advocated, but
concerns about the lower pregnancy rate after reducing the number of embryos transferred …

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 …

Implantation is the first step in human reproduction. Successful implantation depends on the
crosstalk between embryo and endometrium. Recurrent implantation failure (RIF) is a …

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 In vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatments
conventionally consist of a fresh embryo transfer, possibly followed by one or more …

Objective To compare in vitro fertilization (IVF) outcomes between fresh embryo transfer (ET)
and frozen-thawed ET (the “freeze-all” policy), with fresh ET performed only in cases without …

Abstract BACKGROUND Anti-Mullerian hormone (AMH) is a marker of ovarian reserve
status and represents a good predictor of ovarian response to ovarian hyperstimulation. The …
