The rates and distributions of uterine blood flow (UBF) were measured in conscious castrated ewes during estradiol, progesterone, and combined-hormone regimens. Supplemental progesterone decreased the magnitude of UBF observed on estradiol alone. Progesterone favored distribution of UBF to the uterine caruncles and estradiol favored distribution to the myometrium and uterine cervix. Proportionate endometrial blood flows were similar on all hormone regimens. These observations suggest that estradiol secretion may not be responsible for the definitive increase in UBF observed during ovine pregnancy.
在有意识的去势母羊中，于雌二醇、孕酮及联合激素方案期间测量子宫血流量（UBF）的速率和分布。补充孕酮可降低单独使用雌二醇时观察到的UBF幅度。孕酮有利于UBF向子宫肉阜分布，而雌二醇有利于向子宫肌层和子宫颈分布。在所有激素方案下，子宫内膜血流量比例相似。这些观察结果表明，雌二醇分泌可能不是绵羊妊娠期间观察到的UBF最终增加的原因。
