STUDY QUESTION What is the early luteal phase hormonal profile in patients undergoing
ovarian stimulation for IVF/ICSI followed by hCG trigger and a freeze-all strategy without …

Research question Is there an association between the ovulation trigger dose of human
chorionic gonadotrophin (HCG) and endogenous progesterone production during the luteal …

Background Controlled ovarian hyperstimulation (COH) which combining GnRH antagonist
co-treatment and GnRH agonist trigger with an additional 1500 IU hCG luteal rescue on day …

Premature luteinization (PL) refers to a rise in serum progesterone (P) levels on the day of
hCG administration. Most studies used an absolute P level on the day of hCG administration …

Purpose The clinical significance of serum hCG levels after ovulation triggering was studied
previously with conflicting results. Our aim was to study the correlation of hCG levels on the …

Research question Progesterone overproduction during ovarian stimulation is associated
with lower live birth rates (LBR) after fresh embryo transfer. Therefore, circulating P …

Introduction: It has recently been shown that late follicular phase progesterone levels
correlate well with those in the early luteal phase, and that progesterone levels before and …

The aim of this study was to identify whether progesterone measurement on the day after
HCG administration has any additional clinical value, over that obtained from progesterone …

The human chorionic gonadotrophin (HCG) trigger used for final follicular maturation in
connection with assisted reproduction treatment combines ovulation induction and early …

Objective: Our purpose was to determine whether elevated progesterone (P) during
