ST. LOUIS (KMOX) – A new study found in the Journal of the American Medical Association is adding to the debate on hormone replacement therapy.

The study finds that women between 50 and 55 who took synthetic hormones over seven years had no cognitive decline.

“Well this study looked at about 1,500 women, which is a reasonable size, and it showed at the very least that giving synthetic hormones to women between the ages of 50 and 55 did not cause cognitive decline and previous studies have showed that older women definitely developed more symptoms of dementia when they were on these hormones,” says Dr. Sue DeCotiis, a hormone replacement specialist in New York City.

DeCotiis questioned the findings, saying the researchers used outdated horse urine to get the estrogen samples, instead of using human hormones.

“With this study, they were using conjugated equine estrogen, and what that means is they get that from the urine of a horse. So, this is horse estrogen,” she says. “These products are very old. They’re more than 70 years old. They were started to be used in the 1940s and I’m certainly no longer using them in my practice.”

DeCotiis says she would have preferred the researchers used natural human estrogen in this study. She adds that all hormones can’t be put into one category because they are different structurally.
