What Is Erectile Dysfunction?
It is normal for men to experience changes in erectile function, such as taking longer to achieve an erection. When the problem becomes persistent, it can be a sign of a physical or emotional problem.
Dealing with Erectile Dysfunction
Erectile dysfunction is when a man is not able to achieve or maintain an erection sufficient for his sexual needs. It's often a side effect of the treatments for prostate cancer. Some men have chronic, complete erectile dysfunction, called impotence. Others have partial or brief erections.

The male reproductive anatomy includes the bladder, epididymis, penis, scrotum, and prostate gland.
Care of the Uncircumcised Penis
