Abstract

Culturing embryos together in a microdrop of media may improve embryo quality, based on the results of animal studies, however individual identification of the embryos in such a system is not possible. The microwell group culture dish contains 9 or 16 microwells with a minimal well-to-well distance and a specific well morphology that facilitates paracrine and autocrine effects. The microwell group culture dish enables individual identification of the embryos while providing the environment that comes with similar benefits as group culture. Our aim was to investigate whether embryo culture in the microwell group culture dish (Primo Vision Dish, Vitrolife) improves IVF outcomes compared to individual culture in human IVF treatment. Five hundred thirty-two IVF-ET cycles were enrolled in this prospective randomized study in a university hospital. IVF cycles were randomized into microwell group culture and individual culture groups. Primary outcome measure was clinical pregnancy rate and secondary outcome measures were embryo quality, fertilization, implantation, delivery and embryo utilization rates. Fertilization rate in ICSI cycles was significantly higher in the microwell group culture group (70.6% vs. 64.9%, P = 0.001). Clinical pregnancy rate was 50.8% in the group culture and 40.6% in the individual culture (P = 0.022). Live birth rate was 41.5% in microwell and 32.9% in individual culture (P = 0.0496). Embryo utilization rate was higher in microwell group culture than in individual culture (80.6% vs. 75.0%; P < 0.001). Microwell group culture has a beneficial effect on IVF outcome and it also allows following up individual embryo development.
