Barak, Israel  and A. Arav, Israel   We will demonstrate the different techniques of closed system Vitrification. Each participant will try to vitrify oocytes using Sealed SOPS and the VitMaster. We will review and troubleshoot problems which occur during Vitrification, revealing the methods required to solve these problems.   Workshop fee including Congress registration: €2,500 (Two Thousand Five Hundred Euro).
