Accumulation of oil droplets in previtellogenic oocytes of Japanese eel, Anguilla japonica, could be induced in vitro. Co-treatment with very low-density lipoprotein (VLDL) and 11-ketotestosterone (11-KT) resulted in significant oil droplet accumulation. It is therefore suggested that lipids in oil droplets originate, at least in part, from VLDL, and that 11-KT plays an important role in their transfer and/or accumulation into oocytes.
