We provide tailor-made fertility treatment to every patient.

Depending on the cause of infertility, we can create a customized plan to help each patient individually. From timing method to artificial insemination to IVF and ICSI, we have many strategies we can use. With specialized outpatient clinics for implantation failure, recurrent miscarriage, male infertility, and more, we can provide detailed support. In addition, Oak Sumiyoshi in Osaka provides infertility outpatient services and works on IVF cases round the clock, 7 days a week. Oak Ginza can even provide treatment at year’s end and New Year’s.

In addition to advanced reproductive medical technology, we also specialize in patient counseling.

The Oak Clinic Group provides a full range of facilities and advanced technologies.
