Preimplantation genetic diagnosis (PGD) is a medical technology that checks whether the chromosomes and genes of fertilized eggs are defective. Today, even though there isn’t a particular law that prohibits PGD in Japan, it is strictly controlled by The Japan Society of Obstetrics and Gynecology, a very influential organization. Its position is that PGD involves an important moral issue in that choosing a “good” fertilized egg allows one to “select” lives. I disagree. I believe that PGD should be encouraged more in Japan for four reasons:

* The moral issue is not as crucial as they say. PGD is practiced before an egg is implanted in the womb. Even the Japanese government does not consider fertilized eggs to be human beings before implantation.

* The purpose of PGD is not to select a better life or baby but to help women who suffer from sterility or habitual miscarriage. It is said that 66 percent of miscarried children have chromosomal troubles. So if PGD can identify the problem, there is a great probability of preventing miscarriage.

* PGD brings us greater freedom to give birth. Even though the birthrate of Japan is falling, a lot of people still want to have children. PGD enables these people to realize their wish.

* PGD is safe and has been practiced in many countries since 1990.
