ObjectiveTo compare the live birth rate between patients who undergo personalized embryo transfer (pET) after endometrial receptivity array (ERA) versus frozen (FET) with standard timing in first single euploid FET cycles. To report of displacement window implantation (WOI) an infertile population without a history failure.DesignProspective cohort study underwent their programmed FET.SettingPri...

STUDY QUESTION Are childhood measures of phenotype associated with peri-conception parental, IVF treatment and/or embryonic characteristics of IVF children? SUMMARY ANSWER Birthweight, childhood body mass index (BMI) and height of pre-pubertal IVF children were strongly associated with peri-conception factors, including follicular and embryonic characteristics. WHAT IS KNOWN ALREADY A growi...

BACKGROUND The timing of embryo transfer (ET) after in vitro fertilisation (IVF) remains controversial, and there are no reliable guidelines available to prospectively identify which patients would benefit from either day-3 or blastocyst transfer. While blastocyst transfer is generally favoured over day-3 transfers, very few IVF patients get both in the same treatment cycle. CASE DESCRIPTION ...

Abstract Study question Is there a significant intra-individual variability of serum progesterone level on the day theHormone Replacement Therapy Frozen Embryo Transfer(HRT-FET) between two consecutive cycles? Summary answer No measured transfer was shown HRT-FET cycles. What is known already In frozen embryo under HRT, minimum P around transfers necessary to optimize reproductive outcomes. Ind...

Objective: This study aimed to evaluate the effectiveness of elective single embryo transfer (eSET) versus double (DET) in frozen cycles following vitro fertilization (IVF) treatment good prognosis patients. The outcome would provide medical data for multiple pregnancy rate reduction IVF treatment.
 Methods: multicenter retrospective cohort was performed patients undergoing first (FET) at ...
