A total of 424 eggs was recovered from flushings of 176 pairs of oviducts. Of these eggs, 324 were in a state of advanced degeneration (Type 4) and ten appeared to have been recently ovulated (Type 1). The number of eggs/oviduct varied from 0 to 13, most being up to 3 eggs, but fifty oviducts contained no eggs. It is widely believed that unfertilized ova are selectively retained in the oviducts but an alternative explanation for their presence is put forward.
从176对输卵管冲洗液中共回收了424枚卵子。在这些卵子中,324枚处于高度退化状态(4型),10枚似乎是近期排出的(1型)。每条输卵管中的卵子数量从0到13枚不等,多数为3枚及以下,但有50条输卵管未发现卵子。人们普遍认为未受精卵会被选择性地保留在输卵管中,但本文对此提出了另一种解释。
