Abstract
In 7 ewes during late pregnancy, peripheral plasma concentrations of estrogens were correlated with uterine activity (P < 0.01; r = + 0.47). In myometrial tissue, the concentration of progesterone was similar to that in plasma; it rose to a plateau from days 115-130 of pregnancy and then fell, but was still detectable during parturition. Myometrial estrogen concentration was much higher than in plasma; from a peak at days 100-115 it decreased, but rose sharply just before parturition.This publication has 1 reference indexed in Scilit:
