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. Sexual arousal disorders were previously known as frigidity in women and impotence in men, though these have now been replaced with less judgmental terms. Impotence is now known as erectile dysfunction, and frigidity has been replaced with a number of terms describing specific problems with, for example, desire or arousal. For both men and women, these conditions can manifest as an aversion to, and avoidance of, sexual contact with a partner. In men, there may be partial or complete failure to attain or maintain an erection, or a lack of sexual excitement and pleasure in sexual activity. Orgasm disorders are a persistent delay or absence of orgasm following a normal sexual excitement phase. The disorder can occur in both women and men. Again, the SSRI antidepressants are frequent culprits -- these can delay the achievement of orgasm or eliminate it entirely. It is unclear exactly what causes vaginismus, but it is thought that past sexual trauma (such as rape or abuse) may play a role. Another female sexual pain disorder is called vulvodynia or vulvar vestibulitis. In this condition, women experience burning pain during sex which seems to be related to problems with the skin in the vulvar and vaginal areas. The cause is unknown. 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.
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. 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. Erections can change over time, sometimes stronger or weaker than other times. When men are in their teens they often have little control over their erections and obtain erections when not in a sexual situation. For most men this stops in their late teens to early twenties. As men get older, erections may not always be obtained when they want one. Almost every man has the occasional time when their erection is less strong than they would like but sometimes it becomes a 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. Psychological issues such as depression, anxiety, guilt or fear can sometimes cause sexual problems. At one time, these factors were thought to be the major cause of erectile dysfunction. Doctors now know that physical factors are present in most men with erectile dysfunction. However, embarrassment or "performance anxiety" can make a physical problem worse. Erectile dysfunction caused only by psychological causes is found most commonly in young men. 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. Sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis) drugs can cause minor side effects such as flushing and headache, but they have been shown to be safe in most men, including those with heart disease. However, these drugs can interact with other medications and cause dangerously low blood pressure. In particular, they should never be taken with nitroglycerin or other nitrate medications commonly used to treat heart disease. Men with enlarged prostates who take alpha-blocker drugs such tamsulosin (Flomax) or doxazosin (Cardura) should probably avoid PDE5 drugs. If Sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis) drugs don't work or cannot be used because of potential side effects, your doctor can recommend other therapies. The drug alprostadil (Caverject, Edex, Muse) causes blood vessels to widen. This can allow blood to flow more freely in the penis, leading to an erection. The drug can be injected with a tiny needle, or a small pellet (suppository) can be inserted into the opening of the penis. Suppositories like this are effective in approximately two-thirds of men. Injections are effective about 80 percent of the time.

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.

- 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.

- 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
