Control of sex
The process of sexual differentiation is central for reproduction of almost all metazoan, and therefore, for maintenance of practically all multicellular organisms. In sex development, we can distinguish two different processes, sex determination, that is the developmental decision that directs the undifferentiated embryo into a sexually dimorphic individual. In mammals, sex determination equals gonadal development. The second process known as sex differentiation takes place once the sex determination decision has been made through factors produced by the gonads that determine the development of the phenotypic sex. Most of the knowledge on the factors involved in sexual development came from animal models and from studies of cases in whom the genetic or the gonadal sex does not match the phenotypical sex, that is, patients affected by disorders of sex development DSDs. Generally speaking, factors influencing sex determination are transcriptional regulators, whereas factors important for sex differentiation are secreted hormones and their receptors.

In some species of fish, notably tilapia and salmonids, there are problems relating to sexual maturation and there are economic advantages in growing single-sex populations. Tilapia have high fecundity but somatic growth can be stunted when they are kept at high stocking densities. It is virtually essential to have single-sex populations to produce fish in excess of g liveweight. Although tilapia males mature at low body weights they grow significantly faster than females, and so a single-sex population should preferably be male.
