Sexual disorders Physical factors include drugs (alcohol, nicotine, narcotics, stimulants, antihypertensives, antihistamines, and some psychotherapeutic drugs); injuries to the back, problems with an enlarged prostate gland, problems with blood supply, nerve damage (as in spinal cord injuries); or disease (diabetic neuropathy, multiple sclerosis, tumors, and, rarely, tertiary syphilis); failure of various organ systems (such as the heart and lungs); endocrine disorders (thyroid, pituitary, or adrenal gland problems); hormonal deficiencies (low testosterone, estrogen, or androgens); and some birth defects. Sexual dysfunction disorders are generally classified into four categories: sexual desire disorders, sexual arousal disorders, orgasm disorders, and sexual pain disorders. Sexual desire disorders or decreased libido can be caused by a decrease in normal estrogen (in women) or testosterone (in both men and women) production. Other causes may be aging, fatigue, pregnancy, medications (such as the SSRIs) or psychiatric conditions, such as depression and anxiety. 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 pain disorders affect women almost exclusively and are known as dyspareunia (painful intercourse) and vaginismus (an involuntary spasm of the muscles of the vaginal wall that interferes with intercourse). Dyspareunia may be caused by insufficient lubrication (vaginal dryness) in women. Sexual dysfunction is more common in people who abuse alcohol and drugs. It is also more likely in people suffering from diabetes and degenerative neurological disorders. Ongoing psychological problems, difficulty maintaining relationships or chronic disharmony with the current sexual partner can also interfere with sexual function.
The problem of an inadequate erection The problem of an inadequate erection is probably one of the biggest issues a man confronts. Most men experience erectile problems on occasion, but impotence, also called erectile dysfunction, is defined as "the persistent failure to develop and maintain erections of sufficient rigidity for penetrative sexual intercourse." Of course, men have other kinds of sexual problems including lack of desire and problems with ejaculation, yet impotence is the most common and troubling. 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. An erection occurs when the nervous system activates a rapid increase in blood flow. The vascular muscle in the spongy area becomes engorged with blood and the outflow of blood is cut off. An erection can occur as a reflex as we see in spinal cord patients, or can be caused by psychogenic (originating in the mind) stimulation. Numerous sexual stimuli are processed by the brain and transmitted to the penis via the nervous system. 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. Nerves must be working normally for a man to get and keep an erection. Nerve damage can result from diabetes, multiple sclerosis, prostate surgery or damage to the spinal cord. Erectile dysfunction can occur suddenly or gradually. Some men slowly lose the firmness of their erections or how long the erections last. In other men, especially those whose impotence is largely caused by psychological factors, the problem may occur unpredictably and can improve at any time. Despite their difficulties with erections, men with impotence often continue to have normal orgasm and ejaculation. Little is known about how to prevent erectile dysfunction. However, avoiding cigarette smoking and maintaining normal blood pressure and cholesterol levels can help because smoking and high cholesterol can affect blood vessels. Men with diabetes should strive to keep blood sugar levels under control. Because certain medications have been associated with erectile dysfunction, ask your doctor about possible side effects before you start using any new prescription. There are many effective treatments for erectile dysfunction. The most popular option is a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which includes sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis). These drugs, taken in pill form from zero to 60 minutes before sexual activity, work in approximately 70 percent of men, though they are less effective in men with neurological causes of erectile dysfunction such as nerve damage from prostate surgery, diabetes or spinal cord injury.

Antihypertensives
- Reducing or controlling high blood pressure.
Depression
- In psychiatry, a symptom of mood disorder characterized by intense feelings of loss, sadness, hopelessness, failure, and rejection.
Ejaculation
- The expulsion of seminal fluid from the urethra of the penis during orgasm.
- The process of ejecting semen from the penis, and is usually accompanied by orgasm as a result of sexual stimulation.
Erection
- The firm and enlarged condition of a body organ or part when the erectile tissue surrounding it becomes filled with blood, especially such a condition of the penis or clitoris.
Estrogen
- Any of several steroid hormones produced chiefly by the ovaries and responsible for promoting estrus and the development and maintenance of female secondary sex characteristics.
- Any one of a group of hormones synthesized by the reproductive organs and adrenal glands in females and, in lesser quantities, in males.
Frigidity
- The state of marked or abnormal sexual indifference.
- Sexual unresponsiveness (especially of women) and inability to achieve orgasm during intercourse.
Hormone
- A substance, usually a peptide or steroid, produced by one tissue and conveyed by the bloodstream to another to effect physiological activity, such as growth or metabolism.
Orgasm
- The peak of sexual excitement, characterized by strong feelings of pleasure and by a series of involuntary contractions of the muscles of the genitals, usually accompanied by the ejaculation of semen by the male.
- The highest point of sexual excitement, marked by strong feelings of pleasure and marked normally by ejaculation of semen by the male and by vaginal contractions within the female.
Paraplegics
