What can go wrong
The condition itself is benign apart from infertility and the psychological impact of dry orgasm. Off-label sympathomimetics raise blood pressure and heart rate and are cautioned in cardiovascular disease, hypertension, and prostatic obstruction. New-onset retrograde ejaculation without a clear drug or surgical cause should prompt evaluation for diabetes and neurologic disease.
This is something to take to a clinician. The Atlas can tell you what is known about retrograde ejaculation 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.
In retrograde ejaculation, the bladder neck fails to close during emission, so semen flows backward into the bladder instead of forward out the urethra, producing a 'dry' or low-volume orgasm and cloudy first-void urine afterward. It is diagnosed by finding sperm in post-orgasmic urine (distinguishing it from anejaculation/failure of emission). Common causes are alpha-blocker drugs (notably tamsulosin and silodosin), diabetic autonomic neuropathy, and surgery that disrupts the bladder neck or sympathetic nerves (TURP, bladder-neck surgery, RPLND). The main consequence is impaired fertility, which is usually manageable.
Orgasm with little or no semen - because it went backward into the bladder.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
How it works
During emission, sympathetic nerves contract the internal urethral sphincter (bladder neck) to seal the bladder so semen is propelled antegrade. Retrograde ejaculation results when that closure fails: alpha-1 adrenergic blockers (especially the uroselective tamsulosin and silodosin) relax the bladder-neck smooth muscle; diabetic autonomic neuropathy or sympathetic nerve injury (RPLND, pelvic/bladder-neck surgery) removes the closing signal; and TURP physically disrupts the bladder neck. Semen then takes the path of least resistance into the bladder.
How it is taken
Reversible cases: stop or switch the offending alpha-blocker or antipsychotic. Pharmacologic attempts to restore antegrade ejaculation use sympathomimetics/anticholinergics off-label (pseudoephedrine, ephedrine, imipramine, midodrine, brompheniramine), timed before sex, with modest and inconsistent success and cardiovascular cautions. When restoration fails and fertility is desired, sperm are retrieved from alkalinized post-orgasm urine (or surgically) for IUI/IVF-ICSI.
What it does to fertility
Fertility is the principal concern: semen is misdirected into the bladder, lowering or eliminating antegrade sperm delivery. Options include stopping a causative drug, off-label sympathomimetics to restore antegrade flow, and sperm retrieval from alkalinized post-orgasm urine for assisted reproduction (IUI or IVF/ICSI), so biological fatherhood usually remains achievable.
What people get wrong
Often saidDry orgasm means you are infertile for good
ActuallyRetrograde ejaculation usually preserves sperm production and orgasm; sperm can often be recovered from the bladder (urine) for assisted reproduction, or antegrade flow restored if a drug cause is stopped.
Often saidA dry orgasm is always retrograde ejaculation
ActuallyDry orgasm can also be failure of emission or anejaculation (no semen produced at all); a post-orgasm urinalysis that is sperm-positive confirms retrograde, while a sperm/fructose-negative result points to failure of emission.
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.
Set against the alternatives
Retrograde ejaculation is distinguished from anejaculation/failure of emission by the post-orgasm urinalysis (sperm present = retrograde). Drug-induced cases (alpha-blockers, antipsychotics) are often reversible by stopping or switching the drug; neurogenic and post-surgical cases are usually permanent and managed for fertility. Among alpha-blockers, silodosin causes the most ejaculatory dysfunction and alfuzosin among the least.

The studies that matter
Silodosin and tamsulosin ejaculatory-dysfunction data2000s-2010s
Uroselective alpha-1A blockers cause high rates of abnormal/retrograde or absent ejaculation; silodosin notably more than tamsulosin, reflecting alpha-1A selectivity at the bladder neck/vas
Sympathomimetic treatment series (pseudoephedrine, imipramine, midodrine)various
Off-label sympathomimetics can restore antegrade ejaculation in some drug-induced or mild neurogenic cases; evidence is limited and uncontrolled
Sperm retrieval from post-orgasm urine / bladderestablished
Sperm recovered from alkalinized urine after orgasm can be used for IUI or IVF/ICSI when antegrade ejaculation cannot be restored
