Sexual Dysfunction Disorders

What are Sexual Dysfunction Disorders?

Sexual Dysfunction Disorders are a group of conditions characterised by persistent problems with sexual response, desire, orgasm, or pain that cause significant distress or interpersonal difficulty.

These disorders can affect any phase of the sexual response cycle and can occur in individuals of any gender, age, or sexual orientation.

Sexual dysfunction becomes a clinical disorder when it causes clinically significant distress or impairment in functioning, occurs persistently or recurrently, and is not better explained by other medical or mental health conditions.

Sexual Response Cycle

Four Phases of Sexual Response

Desire Phase: Interest in sexual activity and sexual thoughts or fantasies.

Arousal Phase: Physical and psychological excitement, including genital changes and increased heart rate.

Orgasm Phase: Peak of sexual pleasure with rhythmic contractions of reproductive organs.

Resolution Phase: Return to pre-arousal state with feelings of relaxation and well-being.

Dysfunction Categories

Desire Disorders: Problems with sexual interest or motivation.

Arousal Disorders: Difficulties with physical or psychological sexual excitement.

Orgasmic Disorders: Problems reaching orgasm or with orgasm intensity.

Pain Disorders: Pain associated with sexual activity.
