A morphological study of subgravid females of Passalurus ambiguus, pinworm of the domestical Rabbit, revealed two remarkable structures: - a tubular egg receptable formed from tissue of the ventral hypodermal cord in the vulvar region in which the total egg production of the female accumulates; - a hypodermal pocket beneath the cuticle in the vulvar region which is used during traumatic insemination, a phenomenon until now unknown in the Nemathelminthes. These structures might be explained as adaptations to the short lifespan of Oxyurid males. Thus, the clustering of eggs in the environment would increase the intensity of infection and therefore the chances of males finding mates. Similarly, the insemination of females before the vulva is formed might be favoured.
对家兔蛲虫——模糊副蛔虫未成熟雌虫的形态学研究揭示了两种显著结构：——一个管状的卵容器，由外阴区域腹侧皮下索的组织形成，雌虫的全部产卵在此处积累；——外阴区域角质层下方的一个皮下袋，在创伤性授精时使用，这种现象在线虫纲中迄今尚不为人知。这些结构或许可以解释为对尖尾线虫雄性寿命短暂的一种适应。因此，卵在环境中的聚集会增加感染强度，进而增加雄性找到配偶的机会。同样，在外阴形成之前对雌虫进行授精可能会更有利。
