Anejaculation & Failure of Emission
Dry orgasm, neurogenic, post-RPLND, and diabetic causes

What can go wrong
The principal consequence is infertility rather than physical danger, but the underlying neurologic or surgical cause matters and should be characterized. Nerve-sparing RPLND techniques have reduced ejaculatory loss compared with older approaches. For men wanting fertility, options include sympathomimetic medications in select cases, penile vibratory stimulation, electroejaculation, or surgical sperm retrieval with assisted reproduction.
This is something to take to a clinician. The Atlas can tell you what is known about anejaculation & failure of emission 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.
Anejaculation is the absence of antegrade ejaculation despite orgasm; failure of emission means semen never reaches the urethra at all. It is distinguished from retrograde ejaculation (where semen passes backward into the bladder) by a post-orgasmic urinalysis that is sperm- and fructose-negative. Major causes are neurogenic: spinal cord injury, retroperitoneal lymph node dissection (RPLND) for testicular cancer, diabetic autonomic neuropathy, multiple sclerosis, and extensive pelvic surgery. Fertility can often still be achieved with sperm-retrieval techniques.
Orgasm with little or no semen, often a wiring problem, not a fading one.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
How it works
Emission depends on coordinated sympathetic outflow contracting the vas, seminal vesicles, and prostate, with bladder-neck closure directing semen forward. Damage to the sympathetic pathways, surgically (classic RPLND), through diabetic autonomic neuropathy, or via spinal cord injury, can abolish emission entirely (failure of emission) or, with bladder-neck incompetence, redirect it backward (retrograde). Distinguishing these guides fertility strategy.
Safety in detail
Penile vibratory stimulation, electroejaculation, and surgical sperm retrieval are medical procedures requiring specialist evaluation and monitoring. Sympathomimetic medications carry cardiovascular risks and require physician oversight.
What people get wrong
Often saidDry orgasm always means semen went into the bladder
ActuallyNot necessarily, failure of emission means no semen is produced at all. A post-orgasm urine test tells the two apart and changes the fertility plan.
Often saidAnejaculation means permanent infertility
ActuallyMany men can father children using vibratory stimulation, electroejaculation, or surgical sperm retrieval combined with assisted reproduction.
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.
