Objective To determine if an increase in plasma P occurring before hCG administration
might impair the outcome of IVF-ET. Design Five hundred eighty-five IVF-ET cycles were …

Objective To clarify whether premature P elevation during controlled ovarian
hyperstimulation (COH) for IVF-ET affects adversely oocyte-embryo quality. Design …

Study question During controlled ovarian stimulation (COS), does the duration of premature
serum progesterone (P) elevation before administration of hCG affect the outcomes of …

Objective: Our purpose was to assess and clarify the mechanism of whether an early
progesterone rise in cycles with gonadotropin-releasing hormone agonist (GnRH-a) is …

In order to explore the relationship between serum progesterone (P) level on the day of
human chorionic gonadotrophin (HCG) administration and cumulative live birth rate in …

Objective To examine the effects of subtle elevation in P levels in late follicular phase on the
outcome of IVF-ET cycles, using GnRH agonist (GnRH-a) and hMG±FSH protocol. Design A …

Objective: To investigate whether the consequences of premature P elevation on IVF-ET
outcome are modulated by the quality of the ovarian response to controlled ovarian …

Objective To assess the effect of an elevated serum P level on the day of hCG administration
in an IVF cycle on resulting embryos by evaluating their performance at subsequent frozen …

OBJECTIVE: To investigate the relationship between serum P levels on the day of hCG
administration and pregnancy outcomes in different responders undergoing IVF. DESIGN …

Objective: To clarify whether embryo development to the blastocyst stage may be affected by
premature P elevation during controlled ovarian hyperstimulation (COH) for IVF-ET with …
