Impact of Dry vs Humidified Culture Conditions on Blastocyst Development and Aneuploidy: A Time-lapse Sibling Oocyte Study

Recruiting now · Not applicable

Conditions studied: Incubator Stay, Total Blastulation, Blastocyst Quality, Biopsy Rate, Fertilization Rate, Ploidy Rate, ICSI

In brief

IVF incubators are essential for maintaining the micro-environment required for embryo development. Incubator technology has progressed from early humidified box systems to benchtop and now time-lapse platforms, driving the development of dry incubator chambers. Both humidified and dry systems have specific pros and cons. Evidence to date suggests that humidified chambers may support better blastocyst development in certain "no-refresh" continuous culture conditions, but current data are limited and study designs remain weak. This study aims to compare sibling oocytes cultured in dry versus humidified chambers within a GERI time-lapse incubator under continuous culture conditions, assessing effects on viability and developmental outcomes. Findings may inform optimal incubation strategies to improve IVF success rates while supporting uninterrupted workflows and potentially improving cost-benefit efficiency in the IVF laboratory.
