Brief summary

Prospective randomized comparison of two widely used in vitro culture system in human IVF treatments. In vitro fertilized oocytes and embryos are cultured in individual culture media droplets using conventional petridish or in group culture using WOW (well of the well) petridish. Primary outcome: implantation and pregnancy rates Secondary outcome: fertilization rate and embryo quality

Interventions

OTHERindividual embryo culture or group culture

Embryos cultured in a 25 microliter droplet of culture media individually in a conventional petridish or in groups of 2-10 embryos in a Well-of-the-Well petridish
