What is
Cryotec?

Cryotec is an innovative method and product line developed by Dr. Masashige Kuwayama and REPROLIFE Inc. for the vitrification and warming of oocytes and embryos. It features simplified protocols, embryologist-friendly product designs, and focuses on achieving high survival rates in cryopreservation.

Why
Cryotec™?

The Cryotec Method is a simple and safe technique for vitrification and warming that can be applied to the cells of any stage, using a unified protocol that leads to outstanding success rates in oocyte preservation, while consistently delivering exceptional outcomes with embryos.



Some of the advantages of
the Cryotec Method include

NO TIME PRESSURE
DURING THE PROCEDURE

thanks to its low toxicity, each step can be carefully observed and confirmed before proceeding.

MINIMIZED
OSMOTIC CHANGES

this means that oocytes and embryos of all stages can be treated using the same protocol, leading to greater efficiency and convenience.

SAFE SOLUTIONS
WITH ULTRA LOW TOXICITY

Cryotec is a safe and effective method even for lower-grade oocytes and embryos that would be difficult to vitrify using traditional methods.

EFFECTIVE FOR SENSITIVE
OOCYTES/EMBRYOS

Cryotec can be used to safely vitrify and warm oocytes and embryos that are sensitive due to the patient's age, constitution, or medical conditions.

OUTSTANDING
SUCCESS RATES

in oocyte preservation, empowering women through pre-emptive oocyte freezing, including those facing infertility due to cancer treatment

Cryotec is Evolving
with Ready to Use

We have obtained clinical performance data for Cryotec Ready to Use (RtU) from nine fertility treatment centers across Japan. The participating centers are located in Kanagawa, Chiba, Tokyo, Iwate, Miyagi, Aichi, Hokkaido, Yamaguchi, and Gifu prefectures. The data is based on 456 embryos that were vitrified and thawed using the Cryotec RtU kit.
