Several species show low sensitivity to IVM, and the development of optimized medium possible oocyte quality and stable growth. Furthermore, adding additive to the medium can effectively reducing development cost and leads to easy handling of oocytes. Isoliquritigenin and formononetin are extracts found in licorice. Previous studies reported that isoliquritigenin and formononetin affected the activity of sperm, but the oocytes are unknown. This study adds isoliquritigenin or formononetin to αMEM to mature oocytes under simple IVC conditions. Recovered oocytes are cultured in αMEM, isoliquritigenincontaining medium and formononetin-containing medium. In study we proved that in addition to the medium, above the quality of oocytes cultured when specific additives were added, more stable growth is possible. collection and IVM of oocyte. SD rats at 6 to 8 wks of age are injected is intraperitoneal with 30 IU/mL of PMSG and 48 hrs later, HCG 50 IU/mL is intraperitoneal injected. Oocytes are collected ovary after 17 hrs. Collected oocytes are cultured for 16 hrs with 200 μL αMEM and 200 μL αMEM containing isoliquritigenin or formononetin at 0, 0.01, 0.02, 0.04, 0.1 mg/mL. Also, isoliquritigenin and formononetin were mixed with 200 μL αMEM at a ratio of 0.25: 0.75, 0.50: 0.50, and 0.75: 0.25 mg/mL respectively. Oocytes supplemented with isoliquritigenin and Formononetin had high quality than oocytes cultured with αMEM and showed an increase in the IVF fertility rate. Our experimental results indicate that using isoliquritigenin, formononetin when cell culture, rather than used only in medium, more effective oocyte quality and stable growth.
