Sexual Dysfunctions in Men and Women

a. Overview

Sexual dysfunctions are conditions which negatively impact the enjoyment of sexual activity by an individual or a couple. Sexual dysfunctions can occur during any phase of sexual activity (desire, arousal, orgasm or resolution) and can be the result of physical and/or psychological factors. Some common categories of sexual dysfunctions are:

Sexual Desire Disorders

Sexual desire disorders are experienced by men and women and are typified by a lack of sexual fantasies and desire for sexual activity. Many cases of low sexual desire are brought on by medication such as anti-depressants or by psychological disorders. Hypoactive sexual desire disorderis a term for cases of low sexual desire that cause distress and which cannot be attributed to any other physical or psychological problems. Studies suggest that approximately 1 in 10 adult women experience cases of hypoactive sexual desire disorder.

Sexual Arousal Disorders

Sexual arousal disorders occur when desire is present, but difficulties are experienced in achieving physiological arousal. In men, an inability to maintain arousal is often known as erectile dysfunction. In women, female sexual arousal disorder refers to the inability to maintain arousal throughout sexual activity.

Premature Ejaculation

Premature ejaculation describes when a man’s ejaculation occurs before his partner has reached satisfaction and is often marked by a lack of ability to control ejaculation.

Orgasm Disorders

In men and women, orgasm disorders such as anorgasmia mark a delay or absence of orgasms following normal sexual activity. Anorgasmia occurs more frequently in women and is more prevalent as women age.

Sexual Pain Disorders

Sexual pain disorders such as dyspareunia and vaginismus occur primarily in women. Dyspareunia refers to pelvic pain during sexual activity, often resulting from physical causes such as infections of the vagina or the surrounding area or ovarian cysts and tumors. Infections of the prostate, bladder, or seminal vesicles, as well as several other diseases or physical causes, can trigger pain in men following ejaculation. Vaginisus is an involuntary tightening of the muscles in the vagina that causes pain with vaginal penetration.

b. Causes

There are many psychological and physiological factors which may contribute to development of sexual dysfunctions. Anxiety, stress, and lack of confidence are common causes of sexual dysfunction in men. Just as feelings of shame and guilt are common causes of sexual dysfunction in women.

Physical factors linked to sexual dysfunction include alcohol use, smoking, and taking psychotherapeutic drugs. For women, sexual dysfunction may be caused with the physiological changes associated with pregnancy or menopause. For men, physiological abnormalities such as enlarged prostate glands and low blood supply can cause various sexual dysfunctions.

Aging is a common cause of sexual dysfunction in both sexes. One factor that causes decreases in sexual activity with aging is a decrease of testosterone and other hormonal changes, which is extremely important to normal sexual functioning in men and women. On average, women in their 60s have half the testosterone level of women in their 40s.

Erectile Dysfunction

a. Overview

Erectile dysfunction occurs when a man is unable to maintain an erection for sexual activity. Occasional difficulty maintaining an erection is not necessarily indicative of ED, and may be caused by factors such as tiredness and alcohol consumption. Only when a man is unable to get an erection the majority of the time would ED be diagnosed and treatment be considered.

Erectile dysfunction is a common disorder among men, affecting 30 million men in the United States alone. Though ED can occur at any age, the frequency of ED increases with aging. While only around 5% of men in their early forties experience ED, as many as 25 percent of men in their mid-sixties experience the disorder.

b. Causes

ED is distinct from other sexual dysfunction such as premature ejaculation or a lack of sexual desire. In cases of erectile dysfunction, sexual desire may be present, but the man is still unable to maintain an erection.

In most cases, ED is the result of physical causes including:
  • poor circulation
  • hormonal imbalance
  • damage to nerves in the spinal cord
  • diabetes
  • obesity
  • low testosterone
In cases of psychological erectile dysfunction, the dysfunction is caused by psychological causes such as:
  • depression
  • anxiety about sexual performance
  • stress
  • relation problems

c. Treatment

Psychological cases of erectile dysfunction are generally treated by psychological counseling. However, since most cases are caused by physical factors, other treatments are typically used, varying based on the nature of the diagnosis. Some of the most commonly prescribed medical treatments are PDE5 inhibitors, and testosterone replacement. Some common natural treatments include compounds such as L-arginine and DHEA and herbs such as yohimbe, ginkgo, and horny goat weed.

PDE5 Inhibitors:

PDE5 inhibitors are drugs such as sildenafil, tadalafil, and verbenafil which inhibit the degradation of PDE5 in the blood, enhancing the effects of nitric oxide and increasing bloodflow to the penis. These drugs, prescribed as oral medications, are better known by their brand names Viagra, Cialis, and Levitra. Though all three drugs use the same physical mechanism, they vary in terms of how long they remain and effective and what side effects they cause.

Commonly experienced side effects with these medications include headaches, nausea, nasal congestion, facial flushing, and diarrhea, though more extreme side effects such as ringing in the ears, vision changes, and painful persistent erections have been reported. Additionally, PDE5 inhibitors, especially in combination with other medications, can result in abnormally low blood pressure, and should not be used if you have heart disease, severe diabetes, or have had a stroke.

Testosterone Replacement:

In cases of erectile dysfunction caused by low levels of testosterone, testosterone supplements can help balance hormone levels. There are various methods for delivering testosterone treatments including injections, a testosterone patch, and oral tablets. Side effects of testosterone replacement can include acne, breast enlargement, water retention, and mood swings.

Life Style Changes:

In addition to medical treatments, certain changes in life style can help reduce ED. Some examples of healthy life style changes are:
  • cessation of smoking
  • discontinuing consumption of alcohol
  • regular exercise
  • reducing daily stress
  • getting enough sleep

Premature Ejaculation

a. Overview

Premature ejaculation (PE) occurs when a man experiences orgasm sooner than he or his partner would wish during sexual activity. PE is a common disorder, affecting as many as one third of all men throughout their lifetimes. Though the average length of intercourse before ejaculation is 4-8 minutes, there is no cut off time that qualifies as premature. While men with PE are usually capable of sexual intercourse, the experience can be unsatisfying for one or both partners, and the man can suffer increased anxiety as a result.

b. Causes

While the exact causes of PE are unknown, most cases of PE are thought to result from psychological factors rather than any particular physical conditions. Cases of primary premature ejaculation begin when an individual reaches puberty, while cases of secondary premature ejaculation develop later in life.

c. Treatment

Since most cases of PE are psychological, the primary methods for treating the dysfunction are sexual therapy, cognitive behavioral therapy and self-treatment. A class of anti-depressants known as SSRIs can also be used to treat PE. Commonly used herbal treatments for PE include angelica, horny goat weed¸ and ginseng. In many cases, multiple treatment methods may be used, such as combining medications and sex therapy.


Most cases of PE resolve on their own; with practice men can learn to control the ejaculatory impulse and to unlearn masturbatory patterns that may have contributed to their PE. Men can practice on their own or with a partner, by focusing on having slow, relaxed sexual interactions. With the squeeze technique, the man or his partner squeezes the penis to prevent ejaculation when the urge arises. By repeating this process over and over again, one becomes used to the sensation and develops better ejaculatory control.

Cognitive Behavioral Therapy:

PE can be very frustrating, causing feelings of anxiety and embarrassment which just make the condition worse. Cognitive behavioral therapy targets the psychological causes of PE. By talking through their relationships and anxieties with a counselor or therapist, patients can learn to manage performance anxiety and cope with stress.


While SSRIs such as Prozac, Paxil, and Zoloft are primarily used as anti-depressants, they may also be used to treat premature ejaculation since inhibited orgasm is a side effect of SSRIs. Results from taking SSRIs typically take a week to develop and may extend sexual stamina anywhere from 6-20 times. Other side effects of these medications include drowsiness, dry mouth, nausea, and decreased libido. In rare cases, use of SSRIs can cause suicidal thoughts and actions.
