Which operations preserve ejaculation?

Start from where you actually are

Worth knowing before you attribute anything to the operation: ejaculatory disorders are already present in close to half of men with lower urinary tract symptoms from an enlarged prostate, before any surgery at all.²

So part of what men fear losing has often already changed. A baseline assessment before surgery is not box-ticking — without it, neither of us can tell afterwards what the operation did.

What happens to erections

Very little, in most men.

A randomised two-centre trial comparing HoLEP with TURP found both lowered the orgasmic-function domain score, with no significant difference between the techniques — and neither showed the collapse in erectile function men fear.³ The pattern across the literature is a transient dip in the early weeks with recovery by three to six months.

New, permanent erectile dysfunction caused by these operations is uncommon. That is not the same as saying nothing changes: men with normal erections beforehand are the group most likely to notice a small decline, which is a consistent finding and one I would rather state than gloss.

What happens to ejaculation, by procedure

This is where the operations genuinely differ, and the differences are large.

TURP removes tissue at the bladder neck, so semen passes backwards into the bladder. Retrograde ejaculation is the expected outcome rather than a complication.

HoLEP removes more tissue still, and the great majority of men ejaculate retrogradely afterwards. There is now randomised evidence for an ejaculation-preserving technique that spares tissue near the bladder neck: it preserved ejaculation and, notably, also improved early continence recovery.⁴ It is not universally offered, and it is a reasonable thing to ask for by name.

Aquablation is the standout on this measure among tissue-removing options. In a randomised comparison against TURP, anejaculation was substantially less common after Aquablation while symptom relief was at least as good, and the advantage was most marked in larger, more complex prostates.⁵ Two-year data confirmed both the efficacy and the ejaculatory advantage held.⁶

Rezūm (water vapour) was designed around this outcome, and a randomised trial reported erectile and ejaculatory function preserved alongside symptom improvement.⁷ A two-year comparison against bipolar TURP is more equivocal, so treat "preserved" as "usually" rather than "always".⁸

UroLift removes no tissue at all and leaves the bladder neck untouched, which is precisely why ejaculation is generally maintained — and precisely why the effect is less durable.⁹

What retrograde ejaculation is actually like

It is worth being concrete, because men imagine something worse than it is.

Orgasm still happens and generally feels the same. What changes is that little or no fluid emerges — the semen passes into the bladder and leaves in the next urine. It is harmless. It is not contraception, and it does matter if you want children, which is a reason to raise fertility before rather than after.

Some men mind very little. Some mind a great deal. Both are legitimate, and neither can be predicted by age: preferences here do not track the assumptions people make about who cares.

The trade, stated plainly

Set the two columns side by side and the decision becomes clearer than any brochure makes it:

• Ejaculation preserved — UroLift, Rezūm, iTIND, and to a large degree Aquablation. Less tissue removed or none. Higher chance of needing further treatment.
• Ejaculation usually lost — TURP and HoLEP. Most tissue removed. Lowest chance of doing this again.

Aquablation is the interesting case precisely because it sits partly in both columns, which is why it attracts the men who want tissue removed without accepting the ejaculatory cost.

Questions worth asking

1. What is my ejaculatory function now, measured rather than assumed?
2. For the procedure you are proposing, what is your own rate of retrograde ejaculation?
3. Do you offer an ejaculation-preserving enucleation technique, and what does it cost me in durability?
4. If preserving ejaculation matters more to me than doing this once, which operation would you pick?

Bottom line

Your erections will probably be much as they are now. Your ejaculation may well not be, and that is the variable to decide on.

If ejaculation is your priority, say so explicitly and accept a higher chance of further treatment. If never repeating this is your priority, accept a dry orgasm. What you should not accept is a recommendation that does not name which of those two you are being sold.

Worth reading alongside: which operation should I have?, will HoLEP cost me my ejaculation?, and will HoLEP affect my erections?.
