DESCRIPTION
  • Premature ejaculation (PE): inability to control ejaculatory reflex resulting in ejaculation sooner than desired; most common type of sexual dysfunction affecting all age groups:
    • Defined (ISSM 2007) as an ejaculation that always or nearly always occurs prior to or within 1 minute of penetration; an inability to ejaculate on all or nearly all penetrations and with negative personal consequences (1,2).
    • Natural biologic response is to ejaculate within 2 to 5 minutes after vaginal penetration.
    • Ejaculatory control is an acquired behavior that increases with experience.
  • Delayed ejaculation (DE): prolonged time to ejaculate (>30 minutes) despite desire, stimulation, and erection
  • Aspermia (lack of sperm in the ejaculate):
    • Anejaculation (AE): lack of emission or contractions of bulbospongiosus muscle
    • Retrograde ejaculation (RE): partial or complete ejaculation of semen into the bladder
    • Obstruction: ejaculatory duct obstruction or urethral obstruction
  • Painful ejaculation: genital or perineal pain during or after ejaculation
  • Ejaculatory anhedonia: normal ejaculation lacking orgasm or pleasure
  • Hematospermia: presence of blood in the ejaculate
  • Ejaculatory duct obstruction
  • Synonym(s): rapid ejaculation; retarded ejaculation; inhibited orgasm in males; ejaculatory dysfunction
EPIDEMIOLOGY
Prevalence
  • PE is common. Reported prevalence in U.S. males ranges from 20-30% depending definition.
  • DE is reported in 5-8% of men age 18 to 59 years, but <3% experience the problem for >6 months.
  • Predominant age: all sexually mature age groups
  • Predominant sex: male only
ETIOLOGY AND PATHOPHYSIOLOGY
Male sexual response:
  • Erection mediated by parasympathetic nervous system
  • Normal ejaculation consists of three phases:
    • Emission phase: Semen is deposited into urethra by contraction of prostate, seminal vesicles, and vas deferens; under autonomic sympathetic control.
    • Ejaculation phase: Semen is forcibly propelled out of urethra by rhythmic contractions of bulbospongiosus and ischiocavernosus muscles. This is mediated by the somatic nervous system on the motor branches of the pudendal nerve. Bladder neck contracture induced by &agr;-adrenergic receptors ensures anterograde ejaculation.
    • Orgasm: the pleasurable sensation associated with ejaculation (cerebral cortex); smooth muscle contraction of accessory sexual organs; release of pressure in posterior urethra
  • PE has many theoretical causes:
    • Penile hypersensitivity
    • 5-hydroxytryptamine (5-HT) receptor sensitivity
    • Sexual inexperience
    • High level of sexual arousal and/or long interval since last ejaculation
    • Fear of sexual transmitted infections (STIs)
    • Anxiety or guilty feelings about sex
    • Lack of privacy
    • Interpersonal maladaptation (e.g., marital problems, unresponsiveness of partner)
  • DE:
    • Rarely due to underlying painful disorder (e.g., prostatitis, seminal vesiculitis)
    • Psychogenic
    • Sexual performance anxiety and other psychosocial factors
    • Medications may impair ejaculation (e.g., MAOIs, SSRIs, &agr;- and &bgr;-blockers, thiazides, antipsychotics, tricyclic and quadricyclic antidepressants, NSAIDs, opiates, alcohol).
  • Never any ejaculate:
    • Congenital structural disorder (Müllerian duct cyst, Wolffian abnormality)
    • Acquired (radical prostatectomy, postinfectious, posttraumatic, T10-T12 neuropathy)
  • AE:
    • Retroperitoneal lymph node (LN) dissection
    • Spinal cord injury or other (traumatic) sympathetic nerve injury
    • Medications (&agr;- and &bgr;-blockers, benzodiazepines, SSRIs, MAOIs, TCAs, antipsychotics, aminocaproic acid
    • Diabetes mellitus (DM) (neuropathy)
    • Radical prostatectomy
  • RE:
    • Transurethral resection of the prostate (25%) or other prostate resection procedures
    • Surgery on the neck of the bladder
    • Extensive pelvic surgery
    • Retroperitoneal LN dissection for testicular cancer (also may produce failure of emission)
    • Neurologic disorders (MS, DM)
    • Medications (&agr;-blockers, in particular tamsulosin, ganglion blockers, antipsychotics)
    • Urethral stricture (may be posttraumatic)
  • Painful ejaculation:
    • Infection or inflammation (orchitis, epididymitis, prostatitis, urethritis)
    • Ejaculatory duct obstruction
    • Seminal vesicle calculi
    • Obstruction of the vas deferens
    • Psychological/functional
  • Ejaculatory anhedonia:
    • Medications
    • Psychological
    • Hormonal imbalances
    • Decreased libido
  • Hematospermia (often unable to find cause):
    • Inflammation/infection
    • Calculi: bladder, seminal vesicle, prostate, urethra
    • Trauma to genital area (cycling, constipation)
    • Obstruction
    • Cyst
    • Tumor (prostate cancer [1-3% present with hematospermia])
    • Arteriovenous malformations
    • Iatrogenic
    • Hypertension
COMMONLY ASSOCIATED CONDITIONS
  • Neurologic disorders (e.g., multiple sclerosis [MS])
  • DM
  • Prostatitis
  • Ejaculatory duct obstruction
  • Urethral stricture
  • Psychological disorders
  • Endocrinopathies
  • Relationship/interpersonal difficulties
image DIAGNOSIS
  • Ejaculation occurs before individual wishes (PE).
  • Ejaculation does not occur following normal stimulation (including masturbation).
PHYSICAL EXAM
  • Check vitals. Look for focal neurologic signs (MS, spinal cord injury) and psychiatric disorders.
  • Thorough GU exam, including:
    • Size and texture of testes and epididymis
    • Verification of the presence of the vas deferens
    • Location and patency of urethral meatus
    • Digital rectal examination to evaluate prostate consistency and size and possible midline lesions
DIAGNOSTIC TESTS & INTERPRETATION
  • Laboratory test results may be normal.
  • Fasting glucose or HgbA1c to rule out diabetes
  • Postorgasmic urinalysis will confirm RE. Semen fructose level, sperm count, and viscosity can be measured. Patient may complain of cloudy urine.
  • AE will have fructose negative, sperm negative, nonviscous postorgasmic urinalysis
  • In painful ejaculation, urinalysis and urine culture
  • If prostate cancer is considered, check prostate-specific antigen (PSA).
  • In anhedonia, consider checking testosterone, prolactin, glucose, and thyroid levels.
  • In hematospermia, painful ejaculation, or if ejaculatory duct obstruction is considered, transrectal ultrasound (TRUS) may be helpful.
  • TRUS-guided seminal vesicle aspiration; if ejaculatory duct obstruction is present, then the aspirate will contain sperm.
  • If suspicious of anatomic abnormality, can get scrotal US and/or MRI
image TREATMENT
GENERAL MEASURES
  • Identifying any medical cause (even if not reversible) helps patient accept condition.
  • Improve partner communication.
  • Psychological counseling for patient and partner
  • P.331

  • Reduce performance pressure through reassurance
  • Use of a variety of resources may be necessary (e.g., psychiatrist, psychologist, sex therapist, vascular surgeon, urologist, endocrinologist, neurologist).
  • PE:
    • Use sensate focus therapy (gradual progression of nonsexual contact to sexual contact).
    • Quiet vagina: female partner stops moving just prior to ejaculation
    • Techniques to learn ejaculatory control (e.g., coronal squeeze technique [squeezing the glans penis until ejaculatory urge ceases] or start-and-stop technique [cessation of penile stimulation when ejaculation approaches and resumption of stimulation when ejaculatory feeling ends]) (3)[B]
  • DE:
    • Change to antidepressant less likely to cause DE (citalopram, fluvoxamine, nefazodone).
  • AE/RE:
    • Discontinue offending medication(s).
    • Diabetic control
    • If urethral obstruction present, refer to urologist
    • RE may be helped if intercourse occurs when bladder is full.
    • Consider penile vibratory stimulation (effective in spinal cord injuries >T10) or electroejaculation (place on monitor if lesions above T6 because autonomic dysreflexia may result) to collect sperm in AE cases.
  • Painful ejaculation:
    • Counseling may be beneficial.
    • If seminal vesicle stones are possible, refer to urologist
  • Hematospermia:
    • Often resolves spontaneously, without known cause
    • May try empiric antibiotic, but little evidence to support
    • If persistent or high degree of suspicion for abnormality, refer to urologist.
MEDICATION
  • PE:
    • Treating underlying erectile dysfunction (if identified) with PDE5 inhibitors
  • First line:
    • Topical anesthetic gel applied (2.5% prilocaine ± 2.5% lidocaine [EMLA]) 2.5 g under a condom for 30 minutes prior to intercourse (4,5)[A]
    • Daily dosing of clomipramine 20 to 50 mg, sertraline 25 to 200 mg, fluoxetine 5 to 20 mg, or paroxetine 10 to 40 mg can delay ejaculation within 1 to 3 weeks of starting medication (4)[A].
    • Dapoxetine, a short-acting SSRI, used “on demand” 30 to 60 mg 1 to 2 hours prior to sex (2,4)[A].
    • Tramadol 5 to 50 mg used “on demand” 2 hours before sex. Effective in many studies (6)[A].
    • Some other “‘on-demand” options include: clomipramine 20 to 40 mg 4 to 24 hours before intercourse, sertraline 50 mg 4 to 8 hours before intercourse, and paroxetine 20 mg 3 to 4 hours before intercourse (2)[A]
    • Consider switching antidepressants to bupropion, nefazodone, or mirtazapine.
    • Second line: behavioral/sex therapy, pelvic floor muscle therapy (3)[B]
  • DE (limited options):
    • Patients who must continue SSRIs may respond to bupropion, buspirone (1)[B], or yohimbine (1)[C] before intercourse.
    • Sex therapy, self-stimulation therapies (1)[B]
    • Some evidence that amantadine or cyproheptadine may be helpful (2)[B]
  • AE/RE:
    • &agr;-Agonists and antihistamines can be helpful but are not approved by the FDA.
    • First line:
      • Pseudoephedrine 60 mg po daily to QID (7)[A]
      • Imipramine 25 to 75 mg po BID (7)[A]
    • Second line: For RE, can try postejaculation bladder harvest of sperm (if fertility desired). For AE, can try midodrine, penile vibratory stimulation, or electroejaculation (7)[B].
  • Painful ejaculation:
    • Treat underlying infection/inflammatory process
    • &agr;-Blockers may have some benefit.
ISSUES FOR REFERRAL
The following conditions, when suspected, should be referred to a urologist:
  • Ejaculatory duct obstruction
  • Seminal vesicle or prostatic stones
  • Urethral obstruction
  • Vas deferens obstruction

Clinical Pearls
&NA;
  • If erectile dysfunction is contributing to ejaculatory difficulty, management of erectile dysfunction should precede attempted management of ejaculatory disorders.
  • Medications should always be thoroughly reviewed because they may be the primary cause of ejaculatory disorders.
  • PE and DE generally have both psychogenic and physical causes, whereas AE and RE are due to organic neurogenic/autonomic dysfunction.
  • A multidisciplinary approach, including the primary care physician, urologists, psychologists, and other appropriate health care professionals, is essential to the proper treatment of ejaculatory disorders.
