What are the next steps for a patient with persistent hematospermia after vasectomy?

Management of Persistent Hematospermia After Vasectomy

For persistent blood in ejaculation after vasectomy, immediately obtain post-vasectomy semen analysis (PVSA) to assess for vasal recanalization, as this symptom complex—particularly when associated with scrotal pain—may indicate vasectomy failure requiring repeat procedure. 1

Immediate Diagnostic Steps

Post-Vasectomy Semen Analysis

• Obtain PVSA immediately regardless of timing post-vasectomy, as persistent hematospermia with or without scrotal pain is a potential harbinger of early recanalization and vasectomy failure 1
• Any motile sperm at any time point indicates vasectomy failure and warrants consideration of repeat vasectomy 2, 3
• Progressive increases in motile sperm counts on serial PVSAs confirm recanalization 1
• Instruct the patient to use alternative contraception (barrier methods) until vasectomy success is confirmed 2, 3

Clinical Evaluation Specific to Post-Vasectomy Context

• Assess timing: hematospermia occurring 2+ months post-vasectomy (beyond expected healing period) is particularly concerning for recanalization 1
• Evaluate for associated scrotal pain, which combined with hematospermia strongly suggests vasal recanalization 1
• Perform physical examination focusing on the vasectomy sites and vas deferens to assess for surgical site issues 1

Age-Stratified Workup Beyond Vasectomy Assessment

If Patient is <40 Years Old

• After ruling out recanalization with PVSA, if hematospermia persists, obtain urinalysis, urine culture, and testing for sexually transmitted infections 2, 4
• Imaging is generally not indicated for isolated transient hematospermia in this age group without other symptoms, as watchful waiting and reassurance suffice 2
• However, persistent or recurrent hematospermia warrants transrectal ultrasound (TRUS) as first-line imaging regardless of age 2

If Patient is ≥40 Years Old

• Obtain prostate-specific antigen (PSA) level to screen for prostate cancer 2
• Perform TRUS as first-line imaging, which detects abnormalities in 82-95% of men with hematospermia, including calcifications, cysts, prostatitis, and masses 2
• If TRUS is negative or inconclusive, proceed to pelvic MRI for superior soft tissue evaluation of the prostate, seminal vesicles, and ejaculatory ducts 2

Laboratory Testing Beyond PVSA

• Urinalysis and urine culture to evaluate for infection 2
• Complete blood count and coagulation studies to assess for bleeding disorders 2
• Serum chemistry panel 2
• Visual analysis of ejaculate for red discoloration 2

Management Algorithm Based on Findings

If Recanalization Confirmed (Motile Sperm Present)

• Counsel patient that vasectomy has failed and alternative contraception must continue 2, 3
• Refer for repeat vasectomy, as surgical exploration will likely reveal vasal recanalization requiring re-occlusion 1
• The risk of pregnancy before repeat vasectomy is the same as pre-vasectomy rates 3

If Azoospermia or Rare Non-Motile Sperm (<100,000/mL)

• Patient may rely on vasectomy for contraception with approximately 1 in 2,000 pregnancy risk 2, 3
• Investigate other causes of hematospermia using age-appropriate algorithm above 2
• Most cases will be benign (infection, inflammation, prostatic calcifications) and self-limited 4, 5, 6

If Persistent Non-Motile Sperm >100,000/mL Beyond 6 Months

• Use clinical judgment based on trends of serial PVSAs and patient preferences to decide if repeat vasectomy is needed 2, 3
• Continue alternative contraception until definitive resolution 2, 3

Critical Pitfalls to Avoid

• Do not assume hematospermia is a normal post-vasectomy finding, especially if occurring beyond the first few weeks or associated with scrotal pain 1
• Do not rely on number of ejaculations as an indicator of vasectomy success; only PVSA results are reliable 2, 3
• Do not clear patients for unprotected intercourse based on home PVSA tests alone, as these have insufficient data for clinical reliability and don't assess motility 2, 3
• Do not dismiss persistent hematospermia in men ≥40 years without PSA testing and imaging, as malignancy must be excluded 2, 4

Intractable Cases

• If clinical evaluation, laboratory testing, and noninvasive imaging (TRUS and MRI) fail to reveal etiology, consider pelvic angiography to evaluate for vascular causes 2
• Transcatheter arterial embolization can be performed if arterial hemorrhage source is identified 2
