[Energy Demand and Its Regulatory Mechanism during Folliculogenesis].

The growth and development of follicles are regulated by genes,hormones and growth factors autocrined and paracrined from granulosa cells,theca cells,and oocytes.Products of glycolysis from granulosa cells such as pyruvate and lactate are one of the main energy sources,which play an important role during folliculogenesis and follicle maturity.Studies on the changes of the products and rate-limiting enzymes during granulosa cells' glycolysis help to clarify the molecular mechanism of energy demand in folliculogenesis and guide the clinical treatment of infertility due to abnormal follicular development.This article reviews recent research advances in the energy demand and regulatory mechanism in different states of folliculogenesis.
