Natural Cycle IVF
Osamu Kato is director of Kato ladies Clinic in Tokyo, Japan. He is an expert in natural IVF and has been pursuing less stimulation of ovary for IVF. He and his colleagues have entertained strong misgivings about the COH protocol for the last 18 years and have attempted to put forth a plan aimed at including ovulation in a way more close to natural ovulation via mild stimulation, ultra-minimal stimulation, Single follicle-single embryo transfer (SF-SET). The global trend over the last 2-3 years seems to endorse his view.
