Dr. Yonezawa

About

Dr. Yonezawa is a physician on the OB-GYN and infertility team at Kiba Park Reproductive Center (Kiba Park Clinic) in Tokyo — one of only five clinics in the city accredited by JISART, Japan’s standardization body for assisted reproductive technology. Dr. Yonezawa appears on the clinic’s Thursday consulting schedule, the other day on which the ART clinic session is extended until 18:30 (source: clinic official website).

The clinic’s couple-based practice covers both female and male factor evaluation under one roof, and Dr. Yonezawa works within that team model.

Clinical Expertise

• Infertility diagnosis and treatment — assessment of common causes such as ovulation disorders and diminished ovarian reserve
• Assisted reproduction cycles — participation in IVF and IUI treatment cycles, from monitoring through transfer
• Full-cycle team care — collaborates with the clinic’s reproductive specialists, embryologists, nurses and hormone coordinators from first-visit work-up to pregnancy confirmation

Why Choose Dr. Yonezawa

Accredited-clinic setting. Dr. Yonezawa practices inside a JISART-accredited clinic, where laboratory and clinical procedures follow Japan’s ART standardization requirements — a distinction held by only five Tokyo clinics (source: clinic official website).

Team-based model. The clinic staffs dedicated infertility counselors, embryologists and hormone coordinators alongside its physicians, so patients are supported through monitoring, stimulation and transfer by a complete team rather than a single doctor.

Evening-session availability. The Thursday rotation overlaps the clinic’s extended ART hours until 18:30 — one of the two weekly evening windows the clinic created so treatment fits around working schedules.
