Groupers of the genus Epinephelus are one of the most important aquaculture species in the world. The sexuality of groupers is almost protogynous hermaphrodite. Since the gonadal re-constriction occurred in adult, grouper provide a good experiment model to investigate the sexual differentiation in vertebrate. Due to the economical and biological importance of groupers, physiological and endocrinological data are eagerly needed for improvement aquaculture. However, the endocrinological mechanism of sex change is not clearly understood. This review addresses the physiological and endocrinological mechanisms and also explains the process of sex differentiation in groupers. Key regulatory factors underlying sex change has been identified to date include sex steroids and follicle stimulating hormone (FSH).
