Long-term T therapy in hypogonadal men is safe, does not increase PCa risk, study finds

Long-term T therapy in hypogonadal men is safe, does not increase PCa risk, study finds

Testosterone (T) therapy is routinely used in men with hypogonadism, a condition in which diminished function of the gonads occurs. Although there is no evidence that T therapy increases the risk of prostate cancer (PCa), there are still concerns and a paucity of long-term data. [More]

Prenatal exposure to phthalate DiNP associated with shorter AGD in Swedish boys: Study

Prenatal exposure to phthalate DiNP associated with shorter AGD in Swedish boys: Study

The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally.

Rockefeller University researchers gain new insight into how cholesterol processes in our body

Rockefeller University researchers gain new insight into how cholesterol processes in our body

In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. Manufactured by the cells themselves, it serves to stiffen the cell's membrane, helping to shape the cell and protect it. By mapping the structure of a key enzyme involved in cholesterol production, Rockefeller University researchers and a colleague in Italy have gained new insight into this complex molecular process.

Hormone loss may cause colon cancer, say Thomas Jefferson University researchers

Hormone loss may cause colon cancer, say Thomas Jefferson University researchers

Some cancers, like breast and prostate cancer, are driven by hormones such as estrogen and testosterone, but to date, there are none that are driven by the lack of a hormone. New evidence suggests that human colon cells may become cancerous when they lose the ability to produce a hormone that helps the cells maintain normal biology. If verified by further studies, it suggests that treating patients at high risk for colon cancer by replacing the hormone guanylin could prevent the development of cancer. [More]
