Japan is experiencing an increase in applications for pre-implantation genetic testing due to relaxed evaluation criteria. The more lenient regulations have stirred greater interest in these procedures that involve fertilizing eggs in a laboratory and testing them for genetic disorders before implantation in the womb. This shift reportedly occurs with advancements in assisted reproductive technologies and evolving societal perceptions on genetic testing.

In Japan, pre-implantation exams are strictly regulated under the Medical Practitioners Act. However, Japan has recently been easing the criteria to broaden its application. It is a society concerned with familial well-being and health, and this news represents a significant progression in the country's approach to reproductive health.

Pre-implantation genetic testing is common in the United States and the European Union, with less stringent regulations compared to Japan. The procedure provides patients with the option of reducing the risk of having a child with a genetic disorder, making it a widely accepted practice. The shift in Japan towards this direction aligns with international norms.
