Retrograde ejaculation caused by incomplete paralysis of pelvic nerve

Area of Science:

• Urology
• Neuroscience

Background:

• Retrograde ejaculation is often idiopathic.
• Neurogenic bladder can affect bladder function and ejaculation.

Observation:

• A case initially diagnosed as idiopathic retrograde ejaculation was investigated.
• Subclinical neurogenic bladder with hypotonic detrusor and normal external urethral sphincter was identified.
• This condition resulted from incomplete pelvic nerve paralysis and normal pudendal nerve activity.

Findings:

• Normal antegrade ejaculation was achieved through a bilateral pudendal nerve block.
• The study suggests some idiopathic retrograde ejaculation cases are linked to neurogenic bladder.

Implications:

• Urodynamic examination is essential for diagnosing neurogenic bladder contributing to retrograde ejaculation.
• This highlights the importance of neurological assessment in ejaculatory dysfunction.
