A new study of aged female rats found that long-term treatment with estrogen and a synthetic progesterone known as MPA increased levels of a protein marker of synapses in the prefrontal cortex, a brain region known to suffer significant losses in aging. The new findings appear to contradict the results of the Women´s Health Initiative, a long-term study begun in 1991 to analyze the effects of hormone therapy on a large sample of healthy postmenopausal women aged 50 to 79. Among other...

UC historian Wendy Kline will present her case study research on coercive birth control used as a form of eugenics. She will present that research at an international conference in Europe on Nov. 11. Eugenics — the science of improving the human population via selective breeding or reproduction — is not a concept confined to past centuries and decades, nor to locales outside the United States. That´s the finding of recent research by University of Cincinnati historian...

The birth control shot Depo Provera offers a convenient alternative for women who don't want to remember to take a daily pill. Ironically, research from Arizona State University has shown the shot actually may impair a person's memory. The ASU study connects medroxyprogesterone acetate (MPA), the hormone active in Depo Provera and many widely used menopausal hormone therapies, to impaired memory in rodents. The study is currently in press in the journal Psychopharmacology. An early on line...

A new look at medical literature found no link between heart attacks and the so-called mini-pills contrary to indication reported earlier that women on the popular contraceptive have a higher risk of heart disease, Reuters Health is reporting. Brands such as Micronor and Ovrette, contain the hormone progestin, but not the estrogen of traditional birth control pills. The results also held for other progestin-only birth control implants and shots. Women worldwide take progestin-only...

BOCA RATON, Fla., Nov. 8, 2010 /PRNewswire/ -- Not all hormones act in the same deleterious way in the body as the combined HRT drugs tested in a study just published in the Journal of the American Medical Association (JAMA). That study showed that combined hormone replacement therapy using Premarin and Provera leads to increased incidences of breast cancer and deaths among post menopausal women. This is hardly news to gynecologists, however, many of whom long ago switched to natural...

Some types of progestins could be used as preventative agent for breast cancer Progestins are used in hormone replacement therapies to counteract the negative effects of estrogen on the uterus and reduce the risk of uterine cancer. However, evidence in recent studies and clinical trials has demonstrated that progestins increase the risk of breast cancer. Now, University of Missouri researchers have compared four types of progestins used in hormone replacement therapies and found significantly...

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior. Contraception alters the chemical cues these scent-reliant animals use to determine genetic fitness, relatedness and individuality. And, as a sort of double whammy to birth-control efforts, male lemurs were shown to be less interested in females that were treated with...
