Ejaculatory disorders

Description
Premature ejaculation: Inability to constantly control the ejaculatory reflex is a common sexual disorder affecting all age groups. Definition criteria vary, e.g., inability to maintain an erection of sufficient duration to satisfy a partner, or ejaculation that occurs before individual wants it to. Natural biological response is to ejaculate within 2 minutes after vaginal penetration. Ejaculatory control is an acquired behavior that increases with experience.

  • Retarded ejaculation: A condition in which erection is normal, or prolonged, but ejaculation does not occur

  • Retrograde ejaculation: The valve at the base of the bladder fails to close during ejaculation and the ejaculate is forced backward into the bladder. Erection and sexual pleasure are usually not diminished.

    System(s) affected: Reproductive, Nervous

    Genetics: No known genetic pattern

    Incidence/Prevalence in USA: Premature ejaculation is common (particularly in the adolescent)

    Predominant age: All age groups

    Predominant sex: Male only

    Signs and symptoms

  • Ejaculation occurring before individual wishes

  • Ejaculation does not occur following normal erection (including masturbation)

    Causes

    • Never any ejaculate
      • Congenital structural disorder (Mullerian duct cyst, Wolffian abnormality)  
      • Acquired (radical prostatectomy, postinfectious, post-traumatic, T10-12 neuropathy)
    • Retrograde ejaculation
       

      • TURP (25%)  
      • Surgery on the neck of the bladder  
      • Extensive pelvic surgery  
      • Retroperitoneal lymph node dissection for testicular cancer (also can produce failure of emission)  
      • Neurologic disorders, eg, multiple sclerosis  
      • Drugs, eg, amoxapine, desipramine, imipramine
    • Retarded ejaculation
       

      • Rarely may be due to underlying painful disorder, eg, prostatitis, seminal vesiculitis  
      • May be psychogenic as part of erectile dysfunction  
      • Sympathectomy, eg, spinal cord injury, diabetes mellitus  
      • Some drugs may impair ejaculation, eg, certain MAO inhibitors, SSRIs, alpha-blockers, antipsychotics, tricyclic antidepressants
    • Premature ejaculation
       

      • Sexual inexperience  
      • High level of sexual arousal  
      • Fear of sexually transmitted disease  
      • Anxiety  
      • Guilty feelings about sex  
      • Interpersonal maladaptation (marital problems, unresponsiveness of mate)  
      • Lack of privacy

    Diagnosis

    Differential Diagnosis: N/A

    Laboratory

  • Laboratory test results are usually normal

  • Post-ejaculate urinalysis will confirm retrograde ejaculation when infertility is a concern

    Drugs that may alter lab results: N/A

    Disorders that may alter lab results: N/A

    Pathological Findings: N/A

    Special Tests
    Look for diabetes, multiple sclerosis, spinal cord injury

    Imaging: N/A

    Diagnostic Procedures
    Detailed sexual history

    Treatment

    Appropriate Health Care
    Outpatient

    General Measures

  • Identification of any medical cause (even if not reversible) helps patient accept condition

  • Improve partner communication

  • Reduce performance pressure through reassurance

  • Use sensate focus therapy

  • Techniques to learn ejaculatory control, e.g., coronal squeeze technique or start-and-stop technique

  • Use of a variety of resources may be necessary, e.g., psychiatrists, psychologists, sex therapists, vascular surgeons, urologists, endocrinologists, neurologists

  • If drugs are a possible cause, consider discontinuing or changing dosage

  • Retrograde ejaculation may be helped if intercourse occurs when bladder is full

    Surgical Measures: N/A

    Activity
    No restrictions

    Diet
    No special diet except for diabetics

    Patient Education
    See General Measures

    Medications

    Drugs of Choice

  • Premature ejaculation may respond to topical anesthesia gel applied under a condom for 30 minutes prior to intercourse. Clomipramine or sertraline have been shown to delay ejaculation for 4-6 minutes.

  • Switching antidepressants to bupropion, nefazodone, or mirtazapine or possibly trazodone often eliminates drug-induced ejaculatory disturbance

  • Retarded orgasm and ejaculation in patients who must continue SSRI drugs may respond to sildenafil

    Contraindications: N/A

    Precautions: N/A

    Significant possible interactions: N/A

    Alternative Drugs: N/A

    Followup

    Patient Monitoring
    As needed depending on type of therapy

    Prevention/Avoidance
    Better sexuality education may reduce problems

    Possible Complications
    Psychological impact on some males - signs of severe inadequacy, self-doubt, additional anxiety and guilt

    Expected Course/Prognosis
    Often improves with therapy and counseling
