What can go wrong

Sympathomimetics carry cardiovascular and blood-pressure risks. EEJ requires anesthesia and carries rectal-injury and, in spinal-cord-injured men, autonomic-dysreflexia risk (a hypertensive emergency) requiring monitoring. PVS can also trigger autonomic dysreflexia. Bladder-recovered sperm are exposed to urine and often have reduced quality, frequently steering couples toward ICSI.

This is something to take to a clinician. The Atlas can tell you what is known about retrograde & anejaculation management in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.

Some men produce sperm but cannot ejaculate it antegrade: retrograde ejaculation (semen flows backward into the bladder) and anejaculation (no emission), common after diabetes, retroperitoneal surgery, spinal cord injury, and certain medications. Management ranges from sympathomimetic drugs and bladder-sperm recovery to penile vibratory stimulation (PVS) and electroejaculation (EEJ), which can retrieve usable sperm for IUI or ICSI even in men who cannot ejaculate at all.

What people take it for

What it is taken for. Approval, where it exists, covers only some of these.

  • Retrograde ejaculation fertility management
  • Anejaculation from spinal cord injury or RPLND
  • Sperm retrieval for IUI/IVF/ICSI
  • Distinguishing ejaculatory from spermatogenic failure

How it works

In retrograde ejaculation, the bladder neck fails to close, so semen enters the bladder; treatment alkalinizes urine and uses sympathomimetics (pseudoephedrine, imipramine) to restore antegrade emission, or recovers sperm directly from post-ejaculatory urine. In anejaculation, PVS triggers the ejaculatory reflex via penile stimulation, and EEJ delivers rectal-probe electrical stimulation of the periprostatic nerves under anesthesia to produce emission - sperm are then processed for ART.

What people get wrong

  • Often saidDry orgasm means you're sterile

    ActuallyRetrograde ejaculation often allows sperm recovery from the bladder, and anejaculation can be managed with PVS or electroejaculation; sperm production is frequently intact.

Who profits, and who pushes back

Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.

How we got here

Electroejaculation was developed first in veterinary and then human andrology through the mid-late 20th century, with penile vibratory stimulation refined especially for spinal-cord-injured men. Combined with ICSI from the 1990s, these techniques made biological fatherhood achievable for men previously considered infertile.

  2. 1980s-1990sPVS refined for spinal cord injury
  3. 1992+ICSI multiplies the value of small retrieved samples

Set against the alternatives

Approach is stepwise: pharmacology and urine recovery for retrograde ejaculation; PVS first for anejaculation (especially SCI), then EEJ under anesthesia if PVS fails; surgical sperm retrieval as a last resort. Retrieved sperm quality usually dictates IUI versus ICSI.

What we do not know

  • Can non-anesthetic, at-home retrieval methods be made reliable for more men?
  • How best to prevent autonomic dysreflexia during PVS/EEJ in high-level spinal injuries?
