Prostate cancer is a "couples disease" that can take a toll on both the patient and his partner, according to a recent review article in Urologic Nursing. 

Researchers analyzed 13 medical studies on the effects of prostate cancer on couples, incorporating partners' perspectives with quotations. 

They identified four common threads in the partners' comments. Partners were concerned about changes in the sexual relationship, the need to learn more about prostate cancer, and the isolation they sometimes felt.

But they also remarked on feelings of togetherness and closeness that developed or strengthened with the cancer diagnosis.

Therapies that stretch the penis could be a viable way to treat Peyronie's disease, suggests a recent review of medical studies. 

One of the hallmarks of Peyronie's disease is a distinct curve in the penis that forms after plaques develop.

The study authors discussed two approaches to stretching treatment. 

First, traction therapy involves wearing a special device designed to straighten the penis by pulling it in the opposite direction of the curve. 

Second, vacuum erection devices use a pump to bring more blood flow into the penis.
