“The authors reported that both sun exposure and supplementation increased serum vitamin D levels, serum testosterone levels, and muscle mass, and decreased 5-meter sprint times. However, they noted that most players did not achieve high levels of vitamin D (greater than 50 ng/ml) by September, which may have affected their results.”

“FTA: > The organismal performance assay detects subtle toxic effects by subjecting mice to a relentless, Darwinian competition for food, shelter and mates. If there is a defect in any physiological system, it is more likely to stand out if test animals have to compete for resources, scientists say.”

“In turn, high insulin levels can stimulate the ovaries to produce more androgens, such as testosterone, and can reduce production of sex hormone-binding globulin, a blood protein that binds testosterone and limits how much of it is active.”

“Interestingly, castration does not cause Parkinson's like symptoms in male mice deficient in iNOS gene, indicating that loss of testosterone causes symptoms via increased nitric oxide production."”

“While it is difficult to establish causation in this study, both DBP and BBP have been shown to lower testosterone in the mother during early pregnancy which could explain how they can affect intellectual development.”

“This PR is early for this particular study, because... again, similar to the BPA stuff posted a moment ago, it hasn't passed peer review yet. It'll be interesting to see where this goes, however.”

“The study included men (19-74 years) with varying glucose sensitivities ranging from normal to type 2 diabetes.”

“Another study found that prostate cancer patients randomized to either active monitoring, surgery or radiation therapy all had the same risk of death from the cancer after 10 years. These results suggest that active monitoring of prostate cancer patients may be as good as early radical treatment and may cause fewer side effects.”
