The purpose of this study was to assess the incidence and direction of the transperitoneal migration of ova in the rabbit. Sixteen New Zealand white rabbits underwent unilateral microsurgical enclosure of either the left (n = 9) or right (n = 7) ovary within a peritoneal bursa. Each animal was bred later to induce ovulation. The fallopian tubes were removed and flushed retrogadely to retrieve ova. The number of transmigrated ova retrieved from the oviduct ipsilateral to the ovary within the bursa was compared with the number of ovulated follicles present on the contralateral ovary. Three ova migrated to the left fallopian tube from a total of 49 ovulation sites on the right ovary. No ova transmigrated to the right oviduct from 33 ovulation sites on the left ovary. Chi-square analysis shows that there is no statistical difference between the tendency to right or left transmigration. This finding substantiates the numerous studies of reproductive physiology in the rabbit that have assumed previously the net transmigration of ova to be zero.
本研究的目的是评估兔卵子经腹膜迁移的发生率和方向。16只新西兰白兔接受了单侧显微手术，将左侧（n = 9）或右侧（n = 7）卵巢封闭在腹膜囊中。随后使每只动物交配以诱导排卵。切除输卵管并逆行冲洗以回收卵子。将从囊内卵巢同侧输卵管回收的迁移卵子数量与对侧卵巢上存在的排卵卵泡数量进行比较。3个卵子从右侧卵巢总共49个排卵位点迁移到左侧输卵管。左侧卵巢33个排卵位点没有卵子迁移到右侧输卵管。卡方分析表明，左右迁移倾向之间没有统计学差异。这一发现证实了先前许多关于兔生殖生理学的研究中假定卵子净迁移为零的观点。
