Management of Retrograde Ejaculation after Transurethral Resection of the Prostate

Introduction to Retrograde Ejaculation

Retrograde ejaculation occurs in approximately 65.4% of patients following TURP, resulting from damage to the bladder neck mechanism during surgery, causing semen to flow backward into the bladder rather than forward through the urethra during ejaculation 1

The risk of retrograde ejaculation is significantly lower with alternative procedures like Transurethral Incision of the Prostate (TUIP), which has only an 18.2% risk, and is recommended for patients with prostates ≤30g 2
TUIP provides equivalent symptomatic improvement to TURP in appropriately selected patients, according to the American Urological Association 3

For younger men planning future fertility, consider TUIP or modified TURP techniques if appropriate for their prostate size, as the anatomical changes from TURP are typically permanent 3
The American Society for Reproductive Medicine recommends considering TUIP for prostates ≤30g to preserve ejaculatory function 2

Sympathomimetic medications, such as pseudoephedrine, ephedrine, and imipramine, can help increase bladder neck tone and potentially restore antegrade ejaculation, but are most effective in partial retrograde ejaculation cases 1

Modified TURP techniques, such as "Minimally Invasive Nonexpensive TURP" with selective resection at 6 and 12 o'clock positions, can preserve antegrade ejaculation in younger patients with smaller prostates, although the evidence is limited 2
Newer technologies like Prostatic Urethral Lift (PUL) may have lower rates of ejaculatory dysfunction, according to the American Urological Association 4

Patients should be counseled on the permanent nature of anatomical changes from TURP, making complete restoration of antegrade ejaculation unlikely, and the limited efficacy of medical management for complete retrograde ejaculation after TURP 1
The psychological aspects of altered sexual function should be addressed, and patients should be referred to a reproductive specialist for intrauterine insemination or other assisted reproductive techniques if fertility is a concern 3
