NEW!
Recently, OPS vitrification performed with commercially available vitrification/warming media was found highly successful for cryopreservation of preimplantation human embryos in all stages of development .
SAGE media use the principles established for OPS and Cryotop vitrification (Vajta et al., 1998; Kuwayama, 2005)

This option means a help for those who may consider to use OPS but have legal/technical obstacles to prepare in-house media.
The price is affordable and the outcome is excellent
