Ejaculatory Disorders
Basics
Description
- Group of dysfunctions involving altered time and control (premature ejaculation [PE], delayed ejaculation [DE]), presence (anejaculation [AE]), direction (retrograde ejaculation [RE]), volume (perceived ejaculate volume reduction [PEVR]), or force (decreased force of ejaculation [DFE]) of ejaculation
- PE is defined as a persistent/recurrent pattern of ejaculation occurring during partnered sexual activity within 1 minute following vaginal penetration and before the individual wishes it + present for 6 months + causing significant distress for individual.
- Natural biologic response is to ejaculate within 2 to 5 minutes after vaginal penetration.
- Ejaculatory control is an acquired behavior that increases with experience.
- Comorbidities common (diabetes, hypertension, sexual desire disorder, erectile dysfunction [ED])
- DE: prolonged time to ejaculate (>30 minutes) despite desire, stimulation, and erection
- Aspermia (lack of sperm in the ejaculate):
- AE: lack of emission or contractions of bulbospongiosus muscle
- RE: partial or complete ejaculation of semen into the bladder
- Obstruction: ejaculatory duct obstruction or urethral obstruction
- Also:
- 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 (often not a serious condition)
Epidemiology
Prevalence
- PE is common; reported prevalence in U.S. males is 5 to 20%.
- DE is reported in 5–8% of men aged 18 to 59 years, but <3% have the problem for >6 months.
- Predominant age: all sexually mature age groups
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, vas deferens; under autonomic sympathetic control
- Ejaculation phase: semen forcibly propelled out of urethra by rhythmic contractions of the bulbospongiosus and ischiocavernosus muscles. This is mediated by the somatic nervous system on the motor branches of the pudendal nerve. Bladder neck contracture by α-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:
- Hypersensitivity/hyperexcitability of glans penis
- 5-hydroxytryptamine (5-HT) receptor sensitivity
- Psychogenic (inexperience, anxiety/guilt, low frequency of sex, relationship problems)
- Urologic (ED, prostatitis, urethritis)
- Endocrine (hyperthyroid, obesity, diabetes)
- Lack of physical or sexual activity
- Withdrawal or detox from prescription or illicit drugs (e.g., opioids)
- DE:
- Rarely due to underlying painful disorder (e.g., prostatitis, seminal vesiculitis)
- Often has a psychogenic component
- Sometimes associated with low testosterone levels
- Sexual performance anxiety and other psychosocial factors
- Drugs or medications may impair ejaculation (e.g., MAOIs, SSRIs, α- and β-blockers, thiazides, antipsychotics, tricyclic antidepressants, NSAIDs, opiates, alcohol, cannabis).
- AE:
- Never has ejaculate: congenital structural disorder (müllerian duct cyst, Wolffian abnormality)
- Acquired causes: surgery (radical prostatectomy, retroperitoneal lymph node [LN] dissection), spinal cord injury or other sympathetic nerve injury (especially T10–T12 level), diabetes mellitus with neuropathy, and medications (α- and β-blockers, benzodiazepines, SSRIs, MAOIs, TCAs, antipsychotics, aminocaproic acid)
- 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 (multiple sclerosis [MS], DM)
- Medications (tamsulosin, other α-blockers, SSRIs, 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
- Hematospermia (often unable to find cause):
- Usually not a serious condition
- Inflammation/infection
- Calculi: bladder, seminal vesicle, prostate, urethra
- Trauma to genital area (cycling, constipation, masturbation)
- Obstruction
- Cyst
- Tumor (1–3% prostate cancers present with hematospermia)
- Arteriovenous malformations
- Iatrogenic
- Hypertension
Risk Factors
ED: pudendal neuralgia; substance use; psychological distress or relationship issue.
General Prevention
Screen for sexual transmitted infections (STIs).

- Neurologic disorders (e.g., MS)
- Diabetes
- Prostatitis
- Ejaculatory duct obstruction
