In fish, as in higher animals, the normal ontogenesis of the gonads is the basis for
successful reproduction. Gonadal differentiation and development depend on the
genetic cascade that programmes the events. Eventually, gonads become the sites
for the maturation of gametes, which are originally derived from the primordial
germ cells (PGCs) and form the cellular basis of reproduction. In fish hormones
of the hypothalamic–pituitary–gonadal (HPG) axis regulate reproduction and
fertility by promoting or inhibiting the production of gonadal sex steroids and
their function. Gonadal sex steroids not only guide proper gonadal development
and function but also play a key role in the activation and regulation of the HPG
axis through two feedback control systems. In this review, we discuss the general
outline and expression pattern of the major genes involved in testicular development
and gonadal steroidogenesis in fish. The review attempts, for the first time,
to collect and discuss recent information regarding the regulation of sex differentiation
and steroidogenic genes during the stages of testicular development and in
response to different external factors. Furthermore, clear insights into the important
genes and their regulation involved in the HPG axis and spermatogenesis are
presented briefly. This review can serve as a guide for fish breeders on the
substances that have a positive impact on reproduction in males.
