Sexual Dysfunctions: Overview, Types, Causes & Treatment

Sexual dysfunctions are persistent disturbances in sexual desire, arousal, orgasm, or pain that cause significant distress. The DSM-5 categorizes them into:

1. Desire Disorders

  • Hypoactive Sexual Desire Disorder (HSDD):
    • Low/no sexual fantasies/desire, not due to another condition (e.g., depression).
    • More common in women but affects men too.
  • Sexual Aversion Disorder:
    • Extreme avoidance of sexual contact due to fear or disgust.

2. Arousal Disorders

  • Female Sexual Interest/Arousal Disorder:
    • Lack of interest, arousal, or pleasure during sex.
  • Erectile Disorder (ED):
    • Inability to attain/maintain an erection in men.

3. Orgasm Disorders

  • Delayed Ejaculation:
    • Persistent difficulty/inability to ejaculate despite arousal.
  • Premature (Early) Ejaculation:
    • Ejaculation within ~1 minute of penetration (lifelong) or reduced latency (acquired).
  • Female Orgasmic Disorder:
    • Difficulty achieving orgasm after sufficient arousal.

4. Sexual Pain Disorders

  • Genito-Pelvic Pain/Penetration Disorder (GPPPD):
    • Pain during penetration (vaginismus or dyspareunia).
    • Fear/tensing of pelvic muscles (common in vulvodynia or trauma history).

Causes

Biological:

  • Hormonal imbalances (low testosterone, menopause).
  • Chronic illness (diabetes, cardiovascular disease).
  • Medications (SSRIs, antihypertensives).

Psychological:

  • Anxiety, depression, PTSD, body image issues.
  • Relationship conflict or poor communication.

Sociocultural:

  • Religious guilt, sexual shame, lack of education.

Treatment

1. Medical Interventions

  • Erectile Dysfunction: PDE5 inhibitors (Viagra, Cialis).
  • Low Desire: Testosterone therapy (controversial in women), flibanserin (Addyi).
  • Pain Disorders: Topical lidocaine, pelvic floor therapy.

2. Psychotherapy

  • Cognitive Behavioral Therapy (CBT): Address negative thoughts.
  • Sensate Focus: Gradual non-sexual touch to reduce performance anxiety.
  • Couples Therapy: Improve intimacy/communication.

3. Lifestyle Changes

  • Exercise, stress reduction, limiting alcohol.

Key Note: A thorough medical/psychological evaluation is essential to rule out underlying causes.
