Masashige Kuwayama

Profile

After setting up the world’s largest center (1989) using In Vitro technology with cows, which was the foundation for human reproductive medical technology, he continued as a leader in key fields such as in vitro fertilization, in-vitro cultivation, and, cryopreservation, developing the world’s leading technologies.
In March of 1999 when he encountered a married couple who were facing the hopeless and unhappy problem of infertility due to age, he decided to devote himself to the development and proliferation of reproductive medical technology which could provide new cures for such patients.
From the following month he transitioned into the field of reproductive medicine and since then has been working vigorously toward the development and proliferation of new treatments.

In May of 1999, he succeeded in the world’s first practical implementation of human oocyte freezing, creating opportunities for single female cancer patients to have children after their cancer treatment.
In 2001 he established the world’s first egg cell bank, and from 2002 he took his work overseas to provide technological guidance.
In 2003 the first baby in America and in 2004 the first babies in South America and Europe were successfully born using Kuwayama’s oocyte cryopreservation technology.
In 2014 the first baby was born using the cryopreserved oocytes of an single blood cancer patient from the Japanese egg cell bank.
In order to spread his superior cryopreservation technology around the world, he devised and developed highly efficient and reproducible human oocyte and embryo cryopreservation techniques as well as holding international academic conferences, workshops and local training classes.
As a result, the cryopreservation techniques developed by Kuwayama have brought happiness to patients around the world.
In 2007 he also succeeded in the world’s first ovarian tissue vitrification preservation, expanding the possibilities for female fertility preservation even further.

Furthermore, in order to solve the problem of oocyte aging in patients with age-based infertility, for which there is currently no effective treatment, he is working vigorously on the development of cytoplasm replacement techniques whereby the concept of organ transplantation is applied to replace the cytoplasm of aged oocytes with young, healthy cytoplasm.
He has already achieved the world’s first success in animal tests and is now waiting for clinical trials.
At the same time, he is devising and developing various peripheral technologies and equipment relating to the manipulation and cultivation of oocytes, sperm, and embryos, such as cultivation vessels and transportation equipment for embryo cultivation, clean benches with constant temperatures for sterile manipulation of embryos and cold clean benches with low-temperature treatment, a low-oxygen cultivation system using the nitrogen in the atmosphere, and dry incubators for human embryos.
