Men of all ages treated for prostate cancer with androgen deprivation therapy, specifically with gonadotropin-releasing hormone agonists, have an increased risk of diabetes and cardiovascular disease, according to a new study.

The natural compound xanthohumol blocks the effects of the male hormone testosterone, therefore aiding in the prevention of prostate cancer.

Researchers have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells -- a process that potentially could be used against a range of chronic viral diseases. The study provides proof-of-principle -- that is, a demonstration of feasibility -- that human stem cells can be engineered into the equivalent of a genetic vaccine.

While it is too early for physicians to start advising their male patients to take up the habit of regular coffee drinking, new data revealed a strong inverse association between coffee consumption and the risk of lethal and advanced prostate cancers.

Getting the correct balance of proteins in our diet may be more important for healthy aging than reducing calories, new research suggests.

It has been thought that men with nonobstructive azoospermia (NOA), a lack of sperm in the semen not caused by an obstruction within the reproductive system, are poor candidates for in vitro fertilization. Now, researchers have shown that sperm from men with NOA and obstructive azoospermia are equally capable of producing embryos.

Researchers have pinpointed a mechanism that may help explain how chromosomal translocations -- the supposedly random shuffling of large chunks of DNA that frequently lead to cancer -- aren't so random after all. They have developed a model of such chromosomal mix-ups in prostate cancer which indicates that the male sex hormone (androgen) receptor unexpectedly plays a key role in driving specific translocations in the development of cancer.
