Sex differentiation is a complex process that requires many factors to regulate gonadal
proliferation, differentiation, development, and organization. In teleosts, the molecular …

Although wild zebrafish possess a ZZ/ZW sex-determination system, domesticated zebrafish
have lost the sex chromosome. They utilize a polygenic sex determination system, where …

Brain sex differentiation is a complex process, wherein genes and steroid hormones act to
induce specific gender brain differentiation. Testosterone (T) derived from the gonads has …

Many animals live in highly social environments, in which individuals must behave in a way
that enables them to survive and live harmoniously among conspecifics. Dominance …

Many fish species exhibit natural sex change as part of their life, providing unique
opportunities to study sexually-differentiated social behaviors and their plasticity. Past …

Fish present remarkable malleability regarding gonadal sex fate. This phenotypic plasticity
enables an organism to adapt to changes in the environment by responding with different …

The major classes of chemicals and brain pathways involved in sexual arousal in mammals
are well studied and are thought to be of an ancient, evolutionarily conserved origin. Here …

Abstract “Brain sex differentiation” in teleosts is a contentious topic of research as most of the
earlier reports tend to suggest that gonadal sex differentiation drives brain sex …

Background Similar to humans, the zebrafish brain plays a central role in regulating sexual
reproduction, maturation and sexual behavior. However, systematic studies of the dimorphic …

Background Our knowledge on zebrafish reproduction is very limited. We generated a
gonad-derived cDNA microarray from zebrafish and used it to analyze large-scale gene …
