In our present study, by using IVM and IVF assays, we showed that rat medicated serum containing YGW can enhance oocyte nuclear maturation in vitro when compared to the blank control and normal rat serum groups.
This result suggests that the YGW formula not only regulate the process of oocyte maturation but also has more effect on subsequent fertilization competence than FSH.
So what are underlying mechanisms of the effects of YGW on oocyte nuclear maturation?
In our present study, we showed that both FSH and YGW increased the oocyte cAMP concentration and the expressions of PKA, CREB, MAPK, MPF, and PKC when compared to the blank control and normal rat serum groups.
Therefore, the more beneficial effects of YGW on the IVF rate when compared to the effects of FSH on the IVF rate may be due to the more beneficial effects of YGW on the quality of oocyte maturation.
As a result, a higher IVF rate could be obtained in the rat medicated serum group containing the YGW than in the FSH group.
In summary, we demonstrated that rat medicated serum containing YGW can enhance the oocyte nuclear maturation in vitro via molecular signal pathways similar to those induced by FSH.
