Estradiol‐17β content in developing eggs and induced sex reversal of the medaka (<i>Oryzias latipes</i>)

20 Jan 2005

Abstract excerpt

To clarify the effect of exogenous estradiol-17beta (E2) on sex differentiation, the E2 content of developing eggs of Oryzias latipes was measured by radioimmunoassay. Endogenous E2 was present in lower concentrations in ovulated, mature eggs in the ovarian cavity than in intrafollicular oocytes. The E2 content of eggs precipitously declined to a minimum level by 2 days post-fertilization. The E2 content of eggs...
