The left uterine horn and ovary (UHOX; n = 25) or just the left ovary (UOX; n = 18) were excised from mature ewes to investigate growth capabilities of the uterus and uterine capacity effects on fetal growth in sheep. The remaining right uterine horns were excised from 5 UHOX ewes on day 13 of the second successive estrous cycle following initial surgery and were compared to 11 left uterine horns previously obtained from UHOX ewes during the midluteal phase of the estrous cycle. Uterine and endometrial content of DNA, RNA, protein, and number of myometrial nuclei indicated that removal of the left uterine horns resulted in hypertrophy of the right uterine horns. The conception rate of the remaining 20 UHOX ewes was lower than of the 18 UOX ewes. However, at 140 days of gestation, there appeared to be no uterine capacity effects on fetal growth.
从成年母羊身上切除左侧子宫角和卵巢（UHOX；n = 25）或仅切除左侧卵巢（UOX；n = 18），以研究绵羊子宫的生长能力以及子宫容量对胎儿生长的影响。在初次手术后的第二个连续发情周期的第13天，从5只UHOX母羊身上切除剩余的右侧子宫角，并与之前在发情周期的黄体中期从UHOX母羊身上获取的11个左侧子宫角进行比较。子宫和子宫内膜中DNA、RNA、蛋白质的含量以及子宫肌层细胞核的数量表明，切除左侧子宫角会导致右侧子宫角肥大。其余20只UHOX母羊的受孕率低于18只UOX母羊。然而，在妊娠140天时，似乎没有子宫容量对胎儿生长的影响。
