Abstract：Sturgeon (Acipenseriformes) is one of the oldest groups of bony fish and holds an important position in the evolutionary history of vertebrates. Most sturgeon species follow a ZW-type female heterogametic sex-determination system, although this is not the only mechanism involved. Slow progress in sturgeon sex differentiation research is attributed to the lack of obvious sexual dimorphism and the long gonadal development cycle. In recent years, various techniques have been employed to screen for candidate genes associated with sex in sturgeon, but no major sex-determining gene has been identified. Since female sturgeon produce roe with higher market value, research into sex control mechanisms has significant potential for applications in breeding and sex regulation. This review systematically summarizes research on sex determination and differentiation in sturgeon, with a focus on the role of transcription factors and transforming growth factor-beta (TGF-β) family genes in the process of sex determination and differentiation. The aim is to provide insights into sturgeon sex determination and differentiation, deepen our understanding of the evolutionary history of sex determination mechanisms in vertebrates, and provide a theoretical basis for sex control breeding in sturgeon.
