Endometrial biopsy specimens (4 or 5 on each occasion) were collected from 7 mares 2, 3, or 4 times over a 50-day period prior to breeding. Four of the collection days were within 6 days of breeding. Six of the 7 mares were diagnosed as pregnant by use of ultrasonography at day 14 after ovulation. This pregnancy rate was the same as that achieved by these mares when they were bred at estrus before the start of the study. It appeared that repeated collection of multiple endometrial biopsy specimens from genitally normal mares did not adversely affect pregnancy rate.
在配种前50天内，从7匹母马身上采集子宫内膜活检样本（每次4或5份），采集2、3或4次。其中4次采集日在配种的6天内。7匹母马中有6匹在排卵后第14天通过超声检查被诊断为怀孕。这个妊娠率与这些母马在研究开始前发情期配种时的妊娠率相同。看来，从生殖系统正常的母马身上反复采集多份子宫内膜活检样本不会对妊娠率产生不利影响。
