The University of Seville and Ginemed have developed a new closed system of cyropreservation, which improves survival rate and fertility of gametes and embryos following years of other closed systems. Now, facing the traditional semi-open straws, SafePreservation, offers the additional security in the conservation of the gametes by eliminating direct contact with the liquid nitrogen (which maintains the material at -196C) – and therefore eliminates the risk of contamination.
This system involves a new straw, thermo-sealed by both extremes, which means that the solution containing the gamete or embryo is hermetically isolated both during the freezing process, as well as during the years it´s kept in preservation, and also in the moment of defrost. SafeSpeed is the fruit of the research which has been implemented as a spin-off by the University of Seville, SafePreservation, over the last years; in the last three, it’s been tested in different clinical trials. Ginemed has accompanied the process along the way, in the different clinical trials, concluding the new procedure supersedes the previous closed system by far, both in the survival rates of the oocytes, spermatozoids, embryos and blastocysts, and also in terms of fertility potential. Communication media such as Telecinco, La Vanguardia, Europa Press and El Economist reported on the news.
