In many reptile species, sexual differentiation of gonads is sensitive to temperature during a
critical period of embryonic development (thermosensitive period, TSP). Experiments carried …

We have previously shown that hexarelin, a novel GH-releasing peptide (GHRP), is able to
elicit GH release when administered iv, sc or by mouth and that it is a more potent GH …

In vertebrates, sex is normally determined by genotype. However, in poikilothermal
vertebrates, including reptiles, amphibians, and fishes, sex determination is greatly …

The phenotypic sex of many teleost fishes including flounders can be experimentally altered
by treating embryos or larvae with varied temperatures or sex-steroid hormones. To analyse …

Japanese flounder (Paralichthys olivaceus), a teleost fish that has XX (female)/XY (male)
sex determination system, exhibits temperature-dependent sex determination. We have …

Estradiol plays a key role in the control of many behavioral and physiological aspects of
reproduction therefore the expression of cytochrome P450 aromatase (CYP19), the enzyme …

Medaka (Oryzias latipes) is a teleost fish with an XX/XY sex determination system. Recently,
it was reported that XX medaka can be sex‐reversed into phenotypic males by exposure to …

A brief review of our current understanding (or lack of understanding) of the molecular basis
of temperature‐dependent sex determination (TSD) in reptiles is presented. Current theories …

The pejerrey (Odontesthes bonariensis) is a teleost fish with strong temperature-dependent
sex determination (TSD). Several studies have shown that dmrt1 and gonadal aromatase …

Study on fish sex differentiation is important both from academic and practical aspects. Foxl2
and Dmrt1 are important transcription factors that should be involved in fish gonadal …
