Information

Sexual difficulties may begin early in a person's life, or they may develop after an individual has previously experienced enjoyable and satisfying sex. A problem may develop gradually over time, or may occur suddenly as a total or partial inability to participate in one or more stages of the sexual act. The causes of sexual difficulties can be physical, psychological, or both.

Emotional factors affecting sex include both interpersonal problems and psychological problems within the individual. Interpersonal problems include marital or relationship problems, or lack of trust and open communication between partners. Personal psychological problems include depression, sexual fears or guilt, or past sexual trauma.

Physical factors contributing to sexual problems include:

• Injuries to the back
• An enlarged prostate gland
• Disease (diabetic neuropathy, multiple sclerosis, tumors, and, rarely, tertiary syphilis)
• Drugs, such as alcohol, nicotine, narcotics, stimulants, antihypertensives (medicines that lower blood pressure), antihistamines, and some psychotherapeutic drugs (used to treat psychological problems such as depression)
• Endocrine disorders (thyroid, pituitary, or adrenal gland problems)
  • Failure of various organs (such as the heart and lungs)
• Hormonal deficiencies (low testosterone, estrogen, or androgens)
• Nerve damage (as in spinal cord injuries)
• Problems with blood supply
• 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 (decreased libido) may be caused by a decrease in the normal production of estrogen (in women) or testosterone (in both men and women). Other causes may be aging, fatigue, pregnancy, and medications -- the SSRI anti-depressants which include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil) are well known for reducing desire in both men and women. Psychiatric conditions, such as depression and anxiety, can also cause decreased libido.

Sexual arousal disorders were previously known as frigidity in women and impotence in men. These have now been replaced with less judgmental terms. Impotence is now known as erectile dysfunction, and frigidity is now described as any of several specific problems with desire, arousal, or anxiety.

For both men and women, these conditions may appear 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.

There may be medical causes for these disorders, such as decreased blood flow or lack of vaginal lubrication. Chronic disease may also contribute to these difficulties, as well as the nature of the relationship between partners. As the success of Viagra attests, many erectile disorders in men may be primarily physical, not psychological conditions.

Orgasm disorders are a persistent delay or absence of orgasm following a normal sexual excitement phase. The disorder occurs in both women and men. Again, the SSRI antidepressants are frequent culprits -- these may delay the achievement of orgasm or eliminate it entirely.
