Erectile Dysfunction among the Male Reproductive System

Arousal stimulates the release of neurotransmitters which remit the smooth muscle in the walls of the arteries to increase the volume of line of business run away into the penis from vessels in the pudendum (genital area). The increased demarcation flow is paired with a decreased outflow, caused in part by pressure on the veins from the expanding corpus cavernosa, and results in a harvest-time in length and diameter of the penis. This is also accompanied by a change in the angle between the penis and the body, bringing the penis up towards the abdomen (Baldwin, 1991, p. 37).

At the bound of the penis is the glans, which is lined with a mucus membrane to concord the area moist and damp. The skin in this area is bass in nerve endings and very sensitive. The foreskin forms a thick, cautionary hood over the glans. It rolls back for urination. During erection, the foreskin rolls back to the gloriole (the area where the glans meets the shaft). The foreskin is surgically removed during circumcision.

The frenulum, a bent of stringy tissue under the glans, stops the foreskin from axial rotation back too far. It has blush more nerve endings than the glans, and the frenulum and glory are the most sensitive areas of the penis (Baldwin, 1991, p. 12). The external curtain raising of the glans is called the meatus and leads to the urethra (p. 13).

The testes lie outside the body in a sack known as the scrotum, which lies behind

Another major factor in erectile disfunction is the side-effects of many commonly order medications and even over-the-counter medications (Gutfeld, 1994, pp. 78-80).

Lafavore (1993, p. 138) report that many antihypertensive medications such as Inderal, Aldomet and clonidine decrease potency (the ability to chance upon and maintain an erection (Baldwin, 1991, p. 191).

One of the main causes of erectile dysfunction in the elderly is the development of atherosclerosis - arterial brass (Lafavore, 1993, p. 130). Plaque disrupts blood flow and thus impedes the inflow of blood into the penis. With insufficient blood flow, the penis cannot erect fully or become rigid enough for penetration.

Diuretics are often prescribed for patients with hypertension, and these may also result in erectile dysfunction. Since many older men suffer from high blood pressure, it is measurable to consider this, and the type of antihypertensive medication the patient is taking, as possible causes of erectile dysfunction in the elderly.
