Topic:Estradiol
Estradiol is a steroid hormone belonging to the estrogen group, which plays a significant role in various physiological processes in horses. It is primarily produced by the ovaries and is involved in the regulation of the estrous cycle, reproductive behavior, and secondary sexual characteristics. In mares, estradiol levels fluctuate throughout the reproductive cycle, influencing follicular development and ovulation. Additionally, estradiol has effects on bone density, muscle growth, and metabolic processes. This page compiles peer-reviewed research studies and scholarly articles that explore the production, function, and clinical implications of estradiol in equine physiology and reproductive health.
The estrogens of the pregnant mare. The urinary ketonic estrogens were studied at monthly intervals in five pregnant mares. Estrone and equilin appear to be the principal components and equilenin a minor constituent of the mares’ estrogens. The levels of equilin rise from the 4–5th months to equal and in some instances exceed those of estrone in the late months of pregnancy. A partition chromatographic method for the separation of the ketonic phenolic steroids of pregnant mares’ urine is described.
