An Overview Of Erection Problems |
An Overview of Erectile DysfunctionErectile dysfunction can be defined as not being able to get and/or keep an erection which enables intercourse to take place. Erection problems occur in any age group: they happen to all men at some point, but for a man not be able to get an erection every time he wishes to have sex is uncommon under forty years of age. However, over this age, there is an increasing occurrence of erection problems, so that about six men in ten over the age of 75 have erection problems. The main reason for this is that vascular problems - blocked penile arteries or leaking veins - occur very much more frequently as men age, and although ageing itself does not cause erectile dysfunction, the physiological changes associated with ageing certainly do. The occurrence of erection problems occurs about ten years earlier on average in diabetic men. Of course, most men need to be physically stimulated to become erect as they get older, erections become less hard, loss of erection becomes more common, sexual intercourse takes place less often, and the refractory period increases. Indeed, older men may not ejaculate every time they have sex. This does not mean that men are less satisfied with sex as they get older, and it remains an important part of a man's self-esteem. The main causes of erection problems are smoking, hypertension (high blood pressure) and other cardiovascular problems. In addition, diabetes and abuse of alcohol are all potential causes of erection problems. Physiology of an erectionA non-erect penis is caused by the action of sympathetic innervation of the smooth muscle found in the corpora cavernosa and the penile arteries. Sensory stimulation and tactile stimulation to the penis will both increase parasympathetic activity and this will result in the penile smooth muscles relaxing, a process which is mediated by activation of the Nitric Oxide / cyclic GMP biochemical system with a concomitant increase in blood flow into and along the penile arteries. This increase in penile blood flow results in an increase in volume of the penile chambers, and an increase in the intracavernous pressure: this increase in pressure in turn causes the penile veins to be compressed against the fibrous capsule (the tunica albuginea) around the internal chambers of the penis, thereby blocking the venous outflow. This is the veno-occlusive mechanism. Causes of erectile dysfunction (origin of erection problems)The main points to note are these: if you have erectile dysfunction you should seek help. We know that most men do not, for those men who have participated in research on treatment are found to have had the problem for more than a year before they are identified. Smoking, high blood pressure, and circulatory or cardiovascular problems, the presence of diabetes and alcohol abuse all add to the potential for erection problems. Erection problems need to be distinguished from penile curvature or Peyronie's disease. Two categories of
