Rowson &amp; Moor (1964) also reported that the increased life-span of the cl in partially hysterectomized sheep was roughly proportional to the amount of uterus removed. Other experiments have demonstrated that the primary effect of theuterus on the ovary is local in nature since unilateral hysterectomy in ewes with cl in both ovaries results in the normal regression of the luteal tissue on the ovary next to the remaining uterine horn, while the cl on the ovary with no uterine connection are maintained for at least 35 days (Moor &amp; Rowson, 1966; Caldwell, Rowson, Moor &amp; Hay, 1969).
