Arousal Disorders: Types, Causes, & Treatment
Arousal disorders involve persistent difficulties in achieving or maintaining the physical and/or psychological excitement needed for sexual activity. The DSM-5 identifies two primary arousal disorders:
1. Female Sexual Interest/Arousal Disorder (FSIAD)
DSM-5 Criteria:
- Lack of/reduced sexual interest, fantasies, or initiation.
- Absent/reduced arousal during sex (e.g., minimal genital or non-genital sensations).
- Symptoms persist for ≥6 months and cause distress.
- Not due to medical conditions (e.g., menopause), substances, or other mental disorders.
Causes:
- Biological:
- Hormonal shifts (menopause, postpartum, breastfeeding).
- Medical conditions (diabetes, cardiovascular disease).
- Medications (SSRIs, hormonal contraceptives).
- Psychological:
- Anxiety, depression, body image issues.
- Past sexual trauma or negative beliefs about sex.
- Relational:
- Lack of emotional intimacy, partner conflict.
Treatment:
- Medical:
- Topical estrogen (for vaginal dryness in menopause).
- Ospemifene (Osphena) for painful intercourse (dyspareunia).
- Filbanserin (Addyi) or bremelanotide (Vyleesi) for premenopausal women.
- Psychological:
- CBT (challenge negative thoughts about sex).
- Mindfulness-based therapy (focus on bodily sensations).
- Sensate focus exercises (non-demand touch to rebuild arousal).
- Lifestyle:
- Pelvic floor therapy, stress reduction, and communication exercises.
2. Erectile Disorder (ED)
DSM-5 Criteria:
- Difficulty attaining/maintaining an erection during sexual activity.
- Symptoms occur in ≥75% of sexual encounters and persist for ≥6 months.
- Causes significant distress.
- Not solely due to another medical condition (e.g., prostate surgery) or substance use.
Causes:
- Biological:
- Vascular disease (e.g., atherosclerosis).
- Neurological disorders (e.g., multiple sclerosis).
- Low testosterone, diabetes, obesity.
- Psychological:
- Performance anxiety, depression.
- Relationship conflict or guilt.
- Lifestyle:
- Smoking, alcohol, sedentary habits.
Treatment:
- Medical:
- PDE5 inhibitors (Viagra, Cialis, Levitra) – first-line treatment.
- Testosterone therapy (if levels are low).
- Vacuum devices or penile implants (for severe cases).
- Psychological:
- CBT for performance anxiety.
- Couples therapy to address relational stressors.
- Lifestyle:
- Exercise, smoking cessation, and reduced alcohol intake.
Key Differences Between FSIAD & Erectile Disorder
| Feature | FSIAD | Erectile Disorder |
|---|---|---|
| Primary Symptom | Lack of mental/physical arousal | Inability to get/maintain erection |
| Common Causes | Hormonal, relational, trauma | Vascular, neurological, anxiety |
| First-Line Treatment | Sensate focus, mindfulness | PDE5 inhibitors (e.g., Viagra) |
When to Seek Help
- If symptoms persist beyond 6 months and cause distress.
- If physical causes (e.g., diabetes, heart disease) are suspected.
- If relationship conflict arises due to sexual difficulties.
