Brief summary
Evaluating the Influence of 3D Culture Dish Design on Preimplantation Genetic Development in Sibling Oocytes: A Randomized Trial
Detailed description
The configuration of culture dishes plays a crucial role in preimplantation embryo development by influencing key culture conditions such as media distribution, oxygen exchange, and embryo spacing, all of which directly impact embryonic growth, fertilization, blastocyst formation, and overall blastocyst quality. Traditional 2D culture dishes provide a flat surface for embryo development, whereas 3D culture dishes create a microenvironment that better mimics in vivo conditions by optimizing nutrient availability and reducing stress from environmental fluctuations. In this study, we compare the effects of two different 3D culture dishes-Dish 1 (Microdrop GPS Dish) and Dish 2 (16-Well BIRR Dish)-on preimplantation genetic outcomes. Using a sibling oocyte split design, oocytes were randomly divided after intracytoplasmic sperm injection (ICSI) and cultured in either dish, ensuring that each patient serves as their own internal control. Embryo development was closely monitored from fertilization to blastocyst formation, to determine whether dish design has a significant impact on preimplantation embryo development.
Interventions
DEVICEMicrodrop GPS dish
The µDrop GPS® micro-wells dish is specifically designed for oocyte and embryo handling and culture. The sloped concave micro-well bottoms of the µDrop GPS® dish allow oocytes and embryos to settle at a central location away from the well walls. The concave nature of the wells provides the thinnest well bottom possible, helping to reduce refraction and allow for optimal visualization. The wells may reduce droplet collapsing/mixing, offer better orientation/optics, and reduce set-up/observation time.
DEVICE16 well BIRR dish
The 16-Well BIRR Dish is a high-quality 3D culture dish designed for optimal embryo handling and identification in IVF. It features well-numbering (1-16) for clear tracking, a large labeling area, and an expanded working space for better accessibility. Its 16 wells allow for increased wash drops and single embryo culture, reducing the number of dishes needed per IVF cycle. Rigorously tested (MEA+, LAL, and SMA per lot), it ensures safe and efficient embryo culture.
