Oogonium develops into early oocyte in the ovary, and then the oocyte leaves the ovary for the coelomic fluid in the form of single cell or cell mass followed by the rapid separation of the group of oocytes into individual ones. Oocyte enters into the nephridium after its maturation. The rupture of germinal vesicle marks the oocyte maturation. Oocyte in the coelom does not have follicle membrane and vitelline membrane is formed and developed by the oocyte itself. Smaller oocyte (0μm in diameter) is round, and larger ones (≥60μm in diameter) is ovate. The short and long diameters of a morphologically mature oocyte are about 115—120μm and 140—145μm respectively, and the vitelline membrane is 7—9μm thick.

卵原细胞在卵巢中发育至早期卵母细胞时期单个或成团脱离卵巢入体腔液中，卵母细胞团细胞很快分离为单个细胞；卵母细胞在体腔液中发育成熟后进入肾管；生发泡破裂是卵母细胞成熟的标志；体腔中卵母细胞无滤泡膜，卵黄膜的形成与发育靠卵母细胞本身；卵径小于60μm的卵母细胞呈圆形，卵径大于60μm 的卵母细胞为卵圆形，形态上成熟的卵母细胞短径约115—120μm、长径约140—145μm、卵黄膜厚7—9μm。
