The success rate of embryo production critically depends on several factors. One of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (IVF) and in vitro embryo culture (IVC) (1, 2). Besides the technique selected for IVF / in vitro embryo production (IVEP), there is an important consideration called IVF/IVEP culture dishes disin...
