In 1999, Kuwayama left the boine world to became head of research at Tokyo's Kato Ladies Clinic, which says it performed nearly 18,000 in-itro fertilization cycles last year. He soon deeloped a quick-freezing method using liquid nitrogen that reduced crystallization and lowered the need for alcohol.

在1999年，Kuwayama离开牛厂去成为东京Kato Ladies Clinic的研究主任，它说，他去年做了18000例体外受精实验，然后不久他发展了用液氮快速冷冻的方法，这种方法不仅降低了结晶而且也减少了对乙醇的需求。
