There may be medical causes to these disorders, such as decreased blood flow or lack of vaginal lubrication. Chronic disease can also contribute, as well as the nature of the relationship between the partners. As the success of sildenafil (Viagra) attests, most erectile disorders in men are primarily physical, not psychological conditions. Sexual dysfunctions are more common in the early adult years, with the majority of people seeking care for such conditions during their late twenties through thirties. The incidence increases again in the geriatric population, typically with gradual onset of symptoms that are associated most commonly with medical causes of sexual dysfunction. A recent study estimates that 30 million men suffer from various degrees of erectile dysfunction. This can range from mild to severe. It is clearly an age-related phenomenon with the prevalence of erectile dysfunction increasing significantly with age. Surprisingly, by the time men reach 40, 5% of them are completely impotent never achieving an erection rigid enough for penetration. Approximately 15% have significant problems achieving or maintaining an erection. The best way for men to begin solving erectile problems is by reading about men's sexual system - anatomy, physiology, diseases, drugs, diagnosis and treatments. Some problems may be solved simply and others may require a visit to your family doctor or a urologist. In either case, we encourage you to become an educated health care consumer, which should help you regardless of the cause or cure for your problem. In order to increase the size of an erection, there must be an increase in blood flow and, at the same time, the blood has to be prevented from leaving the penis. Because erections are caused by the buildup of blood in the shaft of the penis, poor blood flow in the penis can result in problems with erections. Damage to blood vessels can be caused by hardening of the arteries (atherosclerosis) or from trauma. Vascular disease is believed to be the most common medical cause of erectile dysfunction.
