How is retrograde ejaculation managed?

Management of Retrograde Ejaculation

Retrograde ejaculation can be effectively treated with sympathomimetics and alkalinization of urine, with surgical sperm retrieval as an alternative option when medical therapy fails. 1

Diagnosis

Retrograde ejaculation (RE) is characterized by the backward flow of semen into the bladder during ejaculation, resulting in either low seminal volume or complete absence of ejaculate. Diagnosis is confirmed by finding sperm in post-ejaculatory urine analysis.

Treatment Algorithm

First-Line: Medical Management

1. Sympathomimetic Medications:

   • Pseudoephedrine: 60-120 mg taken 120-150 minutes before intercourse 1
   • Ephedrine: 15-60 mg taken 1 hour before intercourse 1
   • Imipramine: 25-75 mg daily 1, 2

2. Combination Therapy:

   • Combined pseudoephedrine and imipramine shows higher success rates (61.5%) compared to either medication alone 2
   • Treatment protocol: Pseudoephedrine 60 mg every 6 hours on the day before ejaculation and two more 60 mg doses on the day of ejaculation 3

3. Urine Alkalinization:

   • Oral sodium bicarbonate to maintain urinary pH between 7.2-8.2 4
   • Adequate hydration to optimize osmolality (300-380 mosmol/kg) 4

Second-Line: Sperm Retrieval for Assisted Reproduction

When medical therapy fails, particularly for fertility purposes:

1. Post-ejaculatory Urine Collection:

   • Alkalinize urine before collection
   • Process collected sperm for intrauterine insemination (IUI) or in vitro fertilization (IVF) 5

2. Induced Ejaculation Techniques:

   • Vibratory stimulation
   • Electroejaculation (particularly useful in neurological causes) 1

3. Surgical Sperm Retrieval:

   • Direct testicular or epididymal sperm extraction when other methods fail 1

Effectiveness of Treatment

• Medical therapy with sympathomimetics can restore antegrade ejaculation in 38-62% of patients 2, 3
• In patients with partial RE, medical treatment significantly increases semen volume, sperm count, and motility 2
• For fertility purposes, sperm retrieved from urine can be successfully used for assisted reproductive techniques, even in older men 5

Factors Affecting Treatment Choice

• Etiology of RE:

  • Diabetic RE: Responds well to medical therapy (success rates up to 70%) 2, 3
  • Post-surgical RE: May be less responsive to medical therapy
  • Neurological RE: May require sperm retrieval techniques

• Fertility Goals:

  • For natural conception: Medical therapy to restore antegrade ejaculation
  • For assisted reproduction: Sperm retrieval from urine may be sufficient

Common Pitfalls and Caveats

• Sympathomimetics may cause hypertension, anxiety, or insomnia - monitor patients with cardiovascular conditions closely
• Imipramine has anticholinergic side effects that may limit tolerability
• Medical therapy is less effective in anatomical causes of RE compared to neurological causes
• For fertility purposes, even partial restoration of antegrade ejaculation can significantly improve chances of successful assisted reproduction 3

Remember that retrograde ejaculation is not life-threatening, so treatment safety should be a primary consideration when selecting therapy 1.
