It is estimated that 20 million men in the United States suffer from sexual dysfunction. Many of these men are not aware of the many options that are available for the treatment of this problem. For a large majority of men who experience sexual dysfunction, the cause is physical rather than psychological. A number of diseases such as high blood pressure, diabetes or even old age may alter sexual functioning. For example, half of all men with diabetes experience some degree of sexual dysfunction.
The penis is one of the external structures of the male reproductive system. The penis has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans penis, which is the cone-shaped end head. The opening of the urethra, the tube that transports semen and urine, is at the tip of the glans penis. The body of the penis is cylindrical in shape and consists of three internal chambers. These chambers are made up of special, sponge-like erectile tissue. This tissue contains thousands of large caverns that fill with blood when the man is sexually aroused. As the penis fills with blood, it becomes rigid and erect, which allows for penetration during sexual intercourse.
Just as high blood pressure can be a sign of cardiovascular disease, your penis if you have one, of course can be a barometer for health problems. The way your penis functions, its appearance, and any abnormal penile fluid or discharge can all point to health issues. The penis has two main functions: to urinate and to ejaculate. Problems urinating, such as difficulty starting or a weak flow of urine, can be a sign of an enlarged prostate.
