Abstract Changes in 17β-estradiol (E2), estrone (E1), testosterone (T), 11-ketotestosterone
(11KT), and 17, 20β-dihydroxy-4-pregnen-3-one (17, 20β-P) levels were correlated to …

Exposure to 17α-ethynylestradiol (EE2, 5 μg/g food) impairs some reproductive events in the
protandrous gilthead seabream and a short recovery period does not allow full recovery. In …

Abstract Circulating estradiol–17β (E2) levels decrease precipitously during female to male
(protogynous) sex change in fish. Whether this drop in E2 levels is a cause or consequence …

Estrogens are responsible for most characteristics of the female sex of a species, such as
metabolic, behavioral, and morphological changes during reproduction. Artificial estradiol …

The effects of giving oral estradiol-17β (E2) and 17α-methyltestosterone (MT) on gonadal
sex differentiation in the F2 hybrid sturgeon, the bester (Huso huso female× Acipenser …

Sex steroids are considered major regulators of sex change processes in fish. Estrogen
depletion is shown to be crucial for female–male sex change initiation; however, its role in …

To assess the potential roles of sex steroids in modulating reproductive processes in the
Zhikong scallop (Chlamys farreri (Jones and Preston, 1904)), variations in estradiol-17β (E2) …

To clarify the cause of sex change recovery after the withdrawal of androgen treatment,
immature female Malabar grouper were fed a diet containing 17alpha-methyltestosterone …

Attempts were made to induce sex reversal of under 2-year-old blue-spotted groupers and to
induce spawning of 4-year-old females. Mature males, through sex reversal, were obtained …

In most hermaphroditic fish, the sexual phase of the gonad responds to external stimuli so
that only one sex remains functional while the other sex becomes dormant. However …
