  • Title: Temperature differences in reproductive tract of nonpregnant ewe.
    Author: Abrams RM, Caton D, Clapp J, Barron DH.
    Journal: Am J Obstet Gynecol; 1971 Jun 01; 110(3):370-5. PubMed ID: 5088376.
    Abstract:
    The effect of estrogens, epinephrine, oxytocin and pituitrin on blood flow through the uterus, cervix vagina, uterine surface uterine vein as well as aorta, liver and cavity of the rumen were measured in waking ewes using thermocouples encased in polyvinyl catheters. Estrone, estradiol and estriol administration led to a reduction in temperature difference between the aorta and reproductive organs. The response was greatest in the temperature of the uterine cavity. The temperature differences between the liver, and cavity of the rumen were unaffected. After the infusion of epinephrine, oxytocin or pituitrin into estrogen-treated ewes, there was an increase in temperature difference compared with the aorta. This may have been caused by the reduction of blood flow to the uterus.
