The ovary in 4-week-old worms contains undifferentiated germ cells. The oogonial differentiation, together with the appearance of some PAS-positive material in the ooplasm occurs in the ovary of 8-week-old worms. The ovary of 16-week-old worms contains only oogonia and oocytes and no germ cells. In adult worms, the oocytes reach the pachytene stage and further development is arrested at this stage. Nucleolar fragmentation and subsequent transport of nuclei to the ooplasm have been observed. The ooplasm contains nutritive material rich in proteins, carbohydrates and lipids. Its amount varies with different stages of oogenesis. The localization of various phosphatases and dehydrogenases was studied during oogenesis and their functional significance was discussed.
4周龄蠕虫的卵巢含有未分化的生殖细胞。卵原细胞分化以及卵质中一些PAS阳性物质的出现发生在8周龄蠕虫的卵巢中。16周龄蠕虫的卵巢仅含有卵原细胞和卵母细胞，没有生殖细胞。在成年蠕虫中，卵母细胞达到粗线期，并且进一步发育在此阶段停滞。已观察到核仁破碎以及随后细胞核向卵质的转运。卵质含有富含蛋白质、碳水化合物和脂质的营养物质。其数量随卵子发生的不同阶段而变化。在卵子发生过程中研究了各种磷酸酶和脱氢酶的定位，并讨论了它们的功能意义。
