Success Rates
Positive Pregnancy Rate and Live Birth Rate
Positive Pregnancy Rates include biochemical, clinical, and live birth cases, which reflects the success rate of each embryo transfer. Biochemical pregnancy is defined as having a β-hCG blood test result of more than or equal to 20 mIU/ml but having no gestational sac on transvaginal ultrasound. A clinical pregnancy is identified with the appearance of a gestational sac on transvaginal ultrasound that did not result in delivery. Live births are pregnancies that have reached 20 weeks’ age of gestation.
From 2012 to 2024, KRBC has conducted a total of 10,584 embryo transfer cycles, of which 5,502 (52.0%) resulted in positive pregnancies, leading to 3,894 (36.8%) live births. The average age of the patients is 36±5, ranging between 18 to 50 years old.
*2024 live birth includes ongoing pregnancies

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.
