This study aimed to investigate tadalafil (Cialis) and aspirin in the treatment of vascular erectile dysfunction (ED). This study found that aspirin can be used alone in the treatment of patients with vascular ED, or combined with tadalafil.

This trial evaluates a specific type of radiation therapy for advanced prostate cancer. The main outcome to be measured is whether or not the therapy will damage the surrounding organs. This trial is taking place in Pennsylvania, USA. 

This study investigated if abiraterone acetate (Zytiga) and prednisone (Deltasone) added to androgen deprivation therapy (ADT) improve survival in patients with advanced prostate cancer. They found that this combination was effective at improving survival in these patients.

Erectile dysfunction is when you cannot get or keep an erection firm enough to have sex. You may have ED if you

• can get an erection sometimes, though not every time
• can get an erection, yet it does not last long enough for sex
• can get an erection, yet it is not firm enough for sex
• are unable to get an erection at all

Prostate cancer is cancer that starts in the prostate gland (figure 1). The prostate gland is a small, walnut-sized structure that makes up part of a man's reproductive system by producing fluid that is part of semen. It sits below the bladder and in front of the rectum, and forms a ring around the urethra, the tube that carries urine out of the body.

Prostate cancer occurs most often in men older than 50. Although prostate cancer is very common, most men do not die from it. This is because prostate cancer usually grows very slowly.
