Nonlinear effects of post-denudation timing on day 3 embryo outcomes in ICSI and evidence for a translatable optimization window
Journal of translational medicine ·doi:10.1186/s12967-026-08586-0

BACKGROUND: Intracytoplasmic sperm injection (ICSI) is performed in over half of assisted reproductive technology cycles globally; however, the optimal interval between oocyte denudation and sperm injection remains undefined in clinical gui…

Two laser-assisted hatching methods of embryos in ART: a systematic review and meta-analysis
BMC pregnancy and childbirth ·doi:10.1186/s12884-024-06380-8

BACKGROUND: Laser-assisted hatching (LAH) stands as the predominant technique for removing the zona pellucida (ZP) in embryos, primarily consisting of two methods: drilling laser-assisted hatching (D-LAH) and thinning laser-assisted hatchin…

Low Endogenous LH on the COS Initiation Day of a GnRH-Agonist Regimen Increases the Risk of Early Pregnancy Loss and Adverse ART Outcomes
Frontiers in endocrinology ·doi:10.3389/fendo.2022.830567

OBJECTIVE: To assess the impact of serum luteinizing hormone (LH) levels on the day of initiation of controlled ovarian stimulation (COS) after pituitary suppression on early pregnancy loss and assisted reproductive technology (ART) outcome…

Progesterone elevation on the day of hCG trigger has detrimental effect on live birth rate in low and intermediate ovarian responders, but not in high responders
Scientific reports ·doi:10.1038/s41598-019-41499-1

Progesterone elevation (PE) on the day of hCG trigger is associated with decreased pregnancy outcome in fresh cycles. Evidence for this comes from overall patient estimates that mostly ignore different ovarian responses. To compare the impa…
