Welcome to Safe Preservation

Embryologists and gynecologists face the dilemma of having to choose between using an open system or a closed system when it comes to vitrifying oocytes or embryos.
This dilemma is even more evident in light of Covid pandemic. In line with the recent guidence published by ESHRE (refer to ESHRE Guidance on Recommencing ART treatments_update 04052020 ), High security straws (like SafeSpeed device) and/or vapour phase storage tanks should be used for cryopreservation of samples from COVID-19 positive patients.
- Open system: excellent results, but there is a risk of contamination.
- Closed system: poor results, although safer</strong at the medical level.
Thanks to the Safespeed method carried out at Safe Preservation</strong, we have obtained for the first time optimal results in oocytes, embryos and blastocysts, as well as subsequent embryonic development.

"SafePreservation ha conseguido con su novedosa técnica un gran avance para todos los embriólogos dedicados a regalar vida y esperanza a muchas madres y padres del mundo"

"... la mejor manera de preservar su fertilidad." "... un método sencillo, eficaz y fiable para la criopreservación de gametos y embriones."

"Porque tratamos cada óvulo y embrión como si fuese un recién nacido, elegimos el mejor sistema para criopreservarlo. Tras más de 10 años de investigaciones podemos decir que SafeSpeed es el sistema más seguro para preservar la fertilidad"

"Safespeed es uno de los métodos de vitrificación más eficientes con los que he trabajado. Con un mínimo de entrenamiento hemos alcanzado tasas de supervivencia en ovocitos del 95%, resolviendo la preocupación existente al riesgo de contaminación al tratarse de un sistema cerrado"
