The present study was carried out with aims at dettecting the effects of different concentrations of soy - phytoestrogens Genistein (GE) and equol (EQ) on farmed female beluga 5 - year - old during a year. Testosterone (T) level was 0.3 ± 0.06 ng/ml at the start and reached to a maximum (21.04 ± 1.91 ng/ml) at EQ 0.4 g/kg at the end of experiment (P<0.05). 17β - estradiol (E2) levels increased significantly at some concentrations of GE and EQ at the end than start and reached to a maximum (12.6 ± 1.04 ng/ml) at EQ 0.4 g/kg at the end of experiment (P<0.05). 17α- hydroxy progesterone (17α - OHP) showed no significant difference. In conclusion, equol at concentration 0.4 g/kg showed more powerful positive effects on testosterone (T) and estradial (E2) than other concentrations of equol and genistein in farmed female Huso huso. Comparatively, EQ showed more estrogenic effects on ovary development in comparison to GE concentrations.
