Evaluating the Influence of 3D Culture Dish Design on Preimplantation Genetic Development in Sibling Oocytes: a Randomized Trial

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.
