Mission
Vision
Our Founder
DR. OSAMU KATO
Dr. Osamu Kato founded the Towako Maternity Clinic in Kanazawa, Japan, where he developed innovative In Vitro Fertilization (IVF) protocols through detailed clinical research in the year 1990. His dedication to excellence led to the establishment of Kato Ladies Clinic in Tokyo’s Shinjuku-ward in 1993, where he continued to advance and perfect his IVF techniques. A visionary in his field, Dr. Kato transformed IVF practices by shifting away from the then-common superovulation methods. Instead, he introduced natural cycle egg retrieval using advanced techniques such as 21–22-gauge needle aspiration. He pioneered the use of Gn-RH analogue triggers to reduce the risk of severe OHSS and was an early advocate for single embryo transfer, significantly lowering the incidence of multiple pregnancies.
Over nearly two decades, Dr. Kato’s protocols evolved into a more natural and physiological approach to follicular stimulation. His IVF laboratory made major advancements in culturing, cryopreservation, and embryo transfer techniques. This combination of natural methods and advanced technology established Kato Ladies Clinic as a leader in Assisted Reproductive Technology (ART) in Japan. Today, the advancements made by Dr. Kato have significantly improved the success rates of IVF treatments while minimizing the physical and emotional strain on patients. The continuation of his legacy through the Kato Medical Group’s expansion into the Philippines is a promising development, bringing his innovative methods to a broader audience and potentially helping more couples achieve their dream of parenthood.
