尝试通过手术将留置硅橡胶球囊导管固定在子宫腔中，从超数排卵的奶牛中收集卵子。从4头插入导管的奶牛中未采集到卵子，表明卵巢活动受到抑制。在该组中，仅发生了16次排卵，而对照组的6头奶牛共记录了121次排卵，收集了84个卵子。此外，插管奶牛的卵巢有6个大囊肿，而对照奶牛中没有记录到囊肿。导管完全冲洗，冲洗液和子宫的细菌学培养显示未发生感染。奶牛对导管的耐受性非常好。没有食欲减退，也没有记录任何异常行为。然而，严重的排卵抑制和卵巢囊性卵泡的形成阻止了该技术作为收集卵子的手段的任何实际应用。
Attempts were made to collect ova from superovulated cows by surgically fixing indwelling silastic balloon catheters in the uterine lumen. No ova were collected from the four catheterised cows and it was shown that ovarian activity was depressed. In this group, only 16 ovulations occurred compared with six control cows in which a total of 121 ovulations were recorded and 84 ova were collected. Also the ovaries of the catheterised cows had six large cysts, whereas no cysts were recorded in the control cows. The catheters flushed perfectly and bacteriological cultures of the flushing and uteri showed that no infections had occurred. The cows tolerated the catheters extremely well. There was no depression in appetite nor was any abnormal behaviour recorded. However, the severe depression of ovulation and the formation of ovarian cystic follicles prevents the technique from having any practical application as a means of collecting ova.
