Abstract
To investigate the hormonal control of previtellogenic oocyte growth in eel, Anguilla australis, ovarian explants were incubated with or without different doses of steroid (11-ketotestosterone, estradiol-17β) or peptide hormones (ovine growth hormone, human insulin-like growth factor-I, human chorionic gonadotropin, porcine insulin) for 18 days. 11-Ketotestosterone, but not estradiol-17β, significantly increased oocyte diameters at physiological doses (30–100 ng/mL). Similarly, incubation with insulin-like growth factor-I, but not any of the other peptide hormones tested, resulted in increased oocyte diameters at high physiological doses (≥30 ng/mL). These data implicate androgens and hormones from the metabolic axis in mediating growth of previtellogenic oocytes in eel.
