The present review focuses on the roles of estrogens and aromatase (Cyp19a1a), the
enzyme needed for their synthesis, in fish gonadal sex differentiation. Based on the recent …

The combined result of the mechanisms of sex determination and sex differentiation is the
sex ratio of a population. Because sex-related growth dimorphism in fish is quite common …

Abstract Small Tail Han sheep, including the FecBBFecBB (Han BB) and FecB+ FecB+
(Han++) genotypes, and Dorset sheep exhibit different fecundities. To identify novel long …

In hermaphroditic fish, the ovotestis can respond to external stimuli so that only one type of
gonadal tissue (either ovarian or testicular tissue) will remain reproductively active and the …

Protandrous black porgy fish, Acanthopagrus schlegeli, have a striking life cycle with a male
sex differentiation at the juvenile stage and male-to-female sex change at 3years of age. We …

Background Teleosts are characterized by a remarkable breadth of sexual mechanisms
including various forms of hermaphroditism. Sparidae is a fish family exhibiting gonochorism …

The protandrous black porgy, Acanthopagrus schlegeli, has a striking life cycle, with sex
differentiation at the juvenile stage, mono-male development, a bisexual gonad during the …

The protandrous black porgy, Acanthopagrus schlegeli, has a striking life cycle with sex
differentiation at the juvenile stage, mono-male development, and male-to-female sex …

Anti-Müllerian hormone (amh), an important regulator of gonad development in male
teleosts, regulates the development and differentiation of germ cells. We performed …

Cytochrome P450 aromatases, encoded by cyp19a1 genes, catalyzes the conversion of
androgens to estrogens and plays important roles in the reproduction of vertebrates …
