The ultrastructural study of oogenesis in T. spiralis makes it possible to subdivide the oocytic growth into 2 phases: a first phase is characterized by an intense nucleolar activity and the transfer of nuclear material to the cytoplasm; a second phase during which the cytoplasmic mass increases and energy reserves (glycogen, lipids) appear. The oocyte does not contain any protein vitellus.
第一阶段的特征是核仁活动强烈且核物质向细胞质转移；第二阶段细胞质质量增加且出现能量储备（糖原、脂质）。卵母细胞不含任何蛋白质卵黄。
