Inguinal Hernia Repair and Erectile Function: Evidence and Counseling Points

The effect of inguinal hernia surgery on erectile function (EF) is generally neutral to slightly positive, but individual variation exists.

Evidence Summary

• Systematic reviews/meta-analyses: No significant difference in EF scores (IIEF-5) pre- vs. post-op at 6–12 months for elective repair. Some show transient decline at 1 month, resolving by 3–6 months.
• Open vs. Laparoscopic (TEP/TAPP): Laparoscopic may have lower acute nerve injury risk (ilioinguinal, iliohypogastric, genital branch of genitofemoral) due to less dissection; long-term EF similar.
• Mesh vs. Non-mesh: Mesh (Lichtenstein) standard; no adverse EF effect. Mesh shrinkage/foreign body sensation rare.
• Bilateral vs. Unilateral: Bilateral may have higher transient neuralgia risk.

Mechanisms of Potential EF Change

• Nerve injury: Ilioinguinal/genitofemoral nerves supply scrotum/penile base; injury → sensory loss, not direct ED. Autonomic fibers to penis run in pelvic plexus (not in inguinal canal).
• Psychological: Pain, scrotal swelling, body image → temporary ED.
• Vascular: Rare; testicular artery injury (if high ligation) → testicular atrophy → hormonal change (long-term).
• Pre-existing ED: Comorbidities (diabetes, CVD, smoking, age) dominate.

Patient Counseling

• EF typically unchanged or improved (relief of hernia-related pain/discomfort during intercourse).
• Transient post-op sexual dysfunction (1–4 weeks) common due to pain/swelling.
• Report persistent numbness/pain → evaluate for neuroma/neuralgia.
• Optimize cardiovascular health (ED often vascular).

Surgeon experience and technique matter more than approach for nerve preservation.
