Additionally, it has been previously reported (Dreiling
et al., 1991) that pregnant ewes exposed to warmer
temperatures had much lower uterine blood flow (20 to
30% lower uterine flow for each 1°C increase in
temperature), had greater circulating oxytocin and
antidiuretic hormones, and produced offspring of much
smaller size. Collectively, heat stress can induce
important changes in the reproductive physiology of the
pregnant uterus and in the future offspring, above and
beyond its commonly discussed effects in oocyte quality
and embryo development.
