Desire, Interest & Arousal Disorders

(I) Male Hypoactive Sexual Desire Disorder:

Male hypoactive sexual desire disorder is a deficiency or absence of sexual fantasies & desire for sexual activity for a minimum duration of 6 months.


Prevalence is highest at Older age (40% at age 66 to 70yrs).

Prevalence at age 18 to 24yrs = 6%.

Factors on which Sexual Desire depends:

  1. Biological Drive.
  2. Adequate self esteem.
  3. Ability to accept oneself as a sexual person.
  4. Availability of appropriate partner.
  5. Good non-sexual relationship with the partner.

Absence of any of the above factors can diminish sexual desire.

Abstinence from sex for a prolonged period can result in suppression of sexual desire.

Diagnosis of male hypoactive sexual desire disorder can not be made unless lack of desire is a source of distress to the patient.

(II) Female sexual interest/ Arousal Disorder:

It is characterized by:

  1. Decrease or paucity of erotic feelings, thoughts or fantasies.
  2. Decreased impulse to initiate sex.
  3. Decreased or absent receptivity to partner overtures.
  4. Inability to respond to partner stimulation.

***symptoms of lack of pleasure are sufficient to make the diagnosis even when vaginal lubrication & congestion are present. A women may lubricate vaginally but may experience loss of excitement or sexual pleasure.

(III) Male Erectile Disorder:

Male erectile disorder was previously called ‘impotence‘. But the term has been dropped.

  • Erectile disorder is the chief complaint of more than 50% of all men attending sexual health clinics.
  • It affects 2-8% of young adults & incidence increases with age.
  • 20% of men fear erectile disorder before their first coitus. Reported incidence of actual erectile disorder during 1st coitus is 8%.


It has been classified into 3 categories:

1. Life long Male Erectile Dysfunction:

They have never been able to obtain an erection sufficient for insertion.

This condition is rare. It occurs in 1% of men younger than age 35.

2. Acquired Male Erectile Disorder:

They have successfully achieved penetration at some time in their lives but are later unable to do so.

It occurs in 10 to 20% of all men.

3. Situational Male Erectile Dysfunction:

They have normal erection in certain circumstances but not in others.

For example, some persons can have normal sexual life with a sex worker but are unable to have an erection in front of his wife/ partner.


  1. Organic
  2. Psychological
  3. Combination of both

***The organic cause of erectile dysfunction may be ruled out if spontaneous erections occur :

  1. when the person doesn’t plan to have intercourse.
  2. at morning time.
  3. while masturbating.
