In Japan doctors can only test which the eggs have problems or not before return them to mother’s body in the case of in-vitro fertilization. When we discuss this theme, we should think at the both points of view of mothers and doctors. Mothers, especially elderly mothers tend to know that the eggs are in order  or disorder than younger ones. Because the late child-bearing has high risk. Furthermore they concentrate their first pregnant more. I give you my thought first . I disagree with such technology. I am going to explain the reason later. But if I were elderly mother, I would like to know the “fact”. The conclusion we can get through the technology may not perfectly correct. But it is the fact that we can get the information to some extent. So I can’t say this test is perfectly bad and we should eliminate such technology.
