Abstract


The development of in vitro culture systems that result to preantral follicles growth and increasing of developmental competency of oocytes obtained from follicles has an important role in fertility preservation and assisted reproductive techniques. In this research, we evaluated the effect of repaglinide on in vitro growth and maturation of preantral follicles. Preantral follicles were isolated from 12-14 day-old female NMRI mice ovaries and cultured for 12 days cultured in α-MEM (Control), α-MEM supplemented with 1µM of repaglinide. Follicles examined for development on 1, 3, 6, 9, 12 days of culture. At the end of culture period after HCG administration in vitro oocyte maturation was assessed. Results showed that in vitro follicle growth, survival, density of granulosa cells and steroidogenic activity were higher than the control group (p less than 0.05). In vitro maturation rate in oocytes derived from follicles in the treatment group was higher than control group (p less than 0.05). Therefore the supplementation of the culture medium with repaglinide can improve the ovarian follicle survival, growth and subsequently in vitro oocyte maturation.
