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

The available literature is controversial regarding the association between the number of
oocytes retrieved and the cumulative live birth rate (CLBR). Although some authors report a …

A retrospective cohort study was performed to examine whether, in artificial endometrial
preparation for frozen embryo transfer (FET) cycles, progesterone (P) levels the day prior to …

STUDY QUESTION Can granulosa cells produce progesterone (P) in response to FSH
stimulation? SUMMARY ANSWER FSH actively promotes P synthesis and output from …

STUDY QUESTION Is elevated late-follicular phase progesterone (EP) associated with a
deleterious impact on embryo quality (EQ) and cumulative live birth rates (LBRs) …

Research question What factors determine serum progesterone concentrations the day
before cryopreserved embryo transfer in artificially prepared cycles? Design Retrospective …

Purpose To evaluate the influence of the endometrial receptivity array (ERA) test on the
implantation rate (IR) and pregnancy rate (PR) in patients with previous failed euploid …

Objective To establish the relationship between the degree of difficulty of ET and pregnancy
rate (PR), with a view to proposing an algorithm for the objective assessment of ET. Design …

STUDY QUESTION Does the presence of FSHR single-nucleotide polymorphisms (SNPs)
affect late follicular phase progesterone and estradiol serum levels in predicted …

Research question Can premature luteinization of granulosa cells (PLGC) act as a novel
