About Us

Cryo Tech Lab was established to capacitate and widespread our technologies on cryopreservation using high performance vitrification to assist the Artificial Reproductive Centers in the world in the preservation of oocytes and embryos with more than 99% of survival, increasing their efficiency and success.

Our developments have been shared with other international researchers achieving amazing results of survival in oocytes and embryos at all stages and the highest standards of pregnancy and live birth. It is the simplest, most efficient method and is leading the world in cryopreservation including ovarian tissue cryopreservation.

Dr. Masashige Kuwayama is a highly skilled embryologist, with more than twenty years of laboratory and clinical experience with both animal and human oocytes and embryos. He has introduced several novel procedures to vitrify oocytes and embryos, including various dilution methods, as well as the Cryotop method and the Cryotip method.

Over the past twelve years, Dr. Kuwayama has taught his vitrification skills to physicians and embryologists in human clinics located in more than 40 countries. This collaboration has resulted in the birth of more than 300,000 babies from vitrified embryos and 40,000 babies from vitrified oocytes fertilized by ICSI.

The Cryotec Method is Dr. Kuwayama’s latest and most innovative method of oocyte and embryo vitrification. It is safe, extremely efficient, and designed to enable physicians and embryologists to help their patients achieve their fervent wish for a healthy baby.

Cryotec Vitrification is suitable for oocytes, blastocysts and cleavage stage embryos.
