OBJECTIVE: The aim of this study was to investigate whether there were differences in the number of good-quality blastocysts after 6 days of treatment with r-hFSH followed by late follicular phase treatment with r-hFSH:r-hLH in a 2:1 fixed …

This paper critically evaluates Sekiguchi et al.'s study of vaginal progesterone dose, serum progesterone thresholds, and reproductive outcomes in hormone replacement therapy frozen embryo transfer (HRT-FET) cycles. The study conflates desc…

INTRODUCTION: Investigation of the number of oocytes recovered from different ovarian stimulation (OS) protocols is essential, as oocyte number is positively associated with the number of good-quality embryos obtained; however, there are fe…

RESEARCH QUESTION: How can outcomes in programmed frozen embryo transfers (FET) be improved, and what are the key areas where more research is needed? DESIGN: Using a Delphi-consensus framework, a scientific committee comprising five exper…

OBJECTIVE: Various gonadotropins are used for ovarian stimulation (OS). This study investigated the cost-effectiveness of different gonadotropins based on real-world data from the French National Health Database (SNDS) over a 7-year follow-…

OBJECTIVE: To assess the adequate ovarian follicular development and oocyte recovery between ovarian potential (antral follicle count [AFC]) before the start of ovarian stimulation (OS) and oocyte quantity and quality at oocyte retrieval. A…

OBJECTIVE: To provide a framework for conducting rigorous nonrandomized studies of interventions in fertility treatment research, addressing their role as complements to randomized controlled trials (RCTs) in evaluating treatment outcomes. …

RESEARCH QUESTION: According to real-world data, is recombinant human FSH (r-hFSH) combined with recombinant human LH (r-hLH) or r-hFSH alone more effective for women of advanced maternal age (AMA) in terms of live birth? DESIGN: Non-inter…

This was a retrospective real-world evidence analysis of the costs per live birth for reference recombinant human follicle-stimulating hormone alfa (r-hFSH-alfa) versus highly purified urinary human menopausal gonadotropin (hMG-HP), based o…

This study compared the cost per live birth and cost-effectiveness of the originator recombinant human follicle-stimulating hormone follitropin alfa (r-hFSH-alfa) and r-hFSH-alfa biosimilars for ovarian stimulation prior to assisted reprodu…

STUDY QUESTION: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting? SUMMARY ANSWER: Consensus definitions for individual core outcomes, contextual sta…

STUDY QUESTION: Does the use of ICSI offer any outcome advantage over IVF in patients with non-male factor infertility? SUMMARY ANSWER: We did not find any outcome improvement that justifies the routine use of ICSI over IVF in non-male fac…

BACKGROUND: Endometriosis has been described to impair fertility through various mechanisms. However, studies evaluating the reproductive outcomes of women undergoing assisted reproductive technologies show controversial results. The aim of…
