Now known to posses long term risks, conjugated equine estrogens, which is made from pregnant horse urine, was one type of hormone replacement therapy, or HRT, that was commonly used. Equine estrogen combined with synthetic progestin makes up this treatment. Because tests showed this particular hormone treatment caused an increase in some cancers, Alzheimer’s, strokes and blood clots, it isn’t used as much. However, it is still prescribed as a short term menopause treatment.
To replace conjugated equine estrogens, Bio-identical hormone therapy was developed. Although some people have their doubts, Bio-identical hormones are made identical to what the human body produces. Long term effects HRT treatment from this haven’t been reported as of yet, due to the lack of testing. Be sure to discuss all treatment options with your doctor.
