About Infertility Treatment

Depending on the cause of infertility, case by case we are moving forward with the treatment of the condition of infertility; from use of the timing method and artificial insemination to In Vitro Fertilization and micro-insemination.
We also set up a specialized outpatient area that has better support for implantation failure, recurrent fetal loss, and male infertility.
In addition, we also handle outpatient infertility and IVF seven days a week.

In the IVF Lab that has state-of-the-art equipment and facilities of the highest standards of a clean room and private electric generator, in order to ensure the quality control of high precision, all fertilized eggs are individually managed by a computer system.


We are actively introducing new technology to develop IVF by employing a large group of academically certified embryologists and providing a research depeartment.
Not only did we focus on the advanced reproductive medicel technology of blastocyst transfer, assisted hatching (AHA), embryo freezing and thawing, testicular sperm extraction (TESE), but we are also focusing a lot on counseling and how to make the body type that is easy to get pregnant.


Oak Group of Osaka kindly offers full facilities and a high level of technology.
