Two new treatments for infertility succeed in pregnancy Yonago Tottori clinic May 16 4:41

If infertility treatment is not successful even after repeated in vitro fertilization due to aging of the egg, etc., a treatment method that removes the protein layer called the "clear zone" that covers the fertilized egg is effective, and two couples have already succeeded in pregnancy. What has been done was revealed by a fertility clinic in Tottori prefecture.

The new treatment method was unveiled at the "Mio Facility Clinic" in Yonago City, Tottori Prefecture.

In the clinic, if the fertilized egg does not grow normally even after repeated in vitro fertilization due to aging of the egg, etc., it is thought that the layer of protein covering the fertilized egg called the "zona pellucida" interferes with cell division, After the consent was obtained from multiple couples, verification was performed, and when the “clear zone” was removed from 69 fertilized eggs immediately after fertilization, 36 fertilized eggs grew normally.

As a result of using this for treatment, two couples in their late thirties who did not grow fertilized eggs after in vitro fertilization more than 10 times succeeded in pregnancy, and another couple in their 40s also had normal fertilized eggs. It is said that they will grow up in the near future and will be transplanted to the uterus soon.

Clinic director Yasuyuki Mio says, "I would like to help a couple who is suffering from difficulty even if they continue to treat infertility due to aging of their eggs."

Expert "May be helpful for patients who do not grow fertilized eggs"

Former Chairman of the Japanese Society of Obstetrics and Gynecology, who is familiar with infertility treatment, and Professor Emeritus Yasunori Yoshimura of Keio University said, `` To date, the zona pellucida has been thought to be necessary to protect cells during fertilized egg division. It can be said that the method of removing all of them is very novel, and it is the result of research that has observed in detail the reason why fertilized eggs do not grow, and there is no adverse effect because they do not stimulate the cells of fertilized eggs. There is a high possibility that it will be helpful for patients who do not grow fertilized eggs even after repeated in vitro fertilization due to aging of eggs, etc. "
