Will HoLEP affect my erections?

What the evidence shows

Most studies of HoLEP report little or no average decline in erectile function on validated measures such as the IIEF-5 or SHIM.¹²³⁴ A narrative review synthesising studies through 2025 reached the same conclusion, describing HoLEP as having a stable erectile profile with at most transient early dips.⁵

The head-to-head comparisons agree. Randomised trials against TURP found no meaningful long-term difference in erectile outcomes,⁶⁷⁸ and meta-analyses of randomised trials support that while also showing HoLEP causes less bleeding, needs a catheter for less time, and shortens hospital stay.⁹¹⁰

So against the operation it is most often compared with, HoLEP is a trade-up in recovery rather than a trade-off in erections.

The nuance the averages hide

An average of zero can conceal two groups moving in opposite directions, and here it does.

A minority of men do report worse erections afterwards — and they are disproportionately the men who had normal erections to begin with.¹¹¹²¹³ In multicentre and prospective datasets the mean stays flat, but subgroup analysis shows a small, real risk of decline in men starting from a normal baseline. Larger prostates may also raise the risk in some cohorts.

If your erections currently work well, that is worth building into the decision. It does not make HoLEP the wrong operation. It makes the conversation a different one from the man who is already on tablets.

Early is not final

Several studies found early dips in erectile and orgasm-related scores which then recovered by three to twelve months.^1415916

The most useful figure comes from a prospective series by an experienced surgeon past the learning curve: erectile function had recovered in 53% of men by one month and 85% by twelve months.¹⁷

A poor result at six weeks is not the answer. It is a stage.

Some of what gets called "ED" is not ED

This is the most common misreading I encounter, and it matters.

Part of the apparent erectile signal after HoLEP is actually a change in orgasm or ejaculation, not in penile rigidity.^11161318 Men use "sexual dysfunction" as one word. The literature separates erections, orgasm, ejaculation and satisfaction — and after this operation they move differently.

A man whose erections are unchanged but whose orgasm feels muted because there is no antegrade ejaculate will often describe that as "the operation affected me sexually". He is right, but not in the way he thinks, and the distinction changes what can be done about it.

That is covered properly on its own page: what HoLEP does to ejaculation.

How this compares with the alternatives

Against TURP and other enucleation techniques, erectile outcomes are broadly similar, and erectile function is generally stable on average after all of them.¹⁹ The main sexual trade-off across this whole family of operations is ejaculation.

Against the minimally invasive procedures — Rezūm, prostatic urethral lift, Aquablation, prostate artery embolisation — the pattern reverses. Those preserve ejaculation better and sometimes short-term sexual scores too, but they generally do not match HoLEP for the completeness of deobstruction, the improvement in flow, or durability.^20212223

That is the actual choice: how much tissue comes out, against how much sexual function stays exactly as it is. There is no option that maximises both.

How strong is the evidence?

Strong for the claim that HoLEP does not on average worsen erections — it rests on randomised trials, meta-analyses and multiple prospective cohorts.⁵⁶⁹¹⁰ Moderate for the subgroup risk in men with normal baseline function, which comes from subgroup analyses rather than from trials designed to test it.¹²¹³ Moderate for the recovery trajectory, which comes largely from single-centre prospective series.¹⁷

Bottom line

If erectile dysfunction is your main worry about prostate surgery, HoLEP is not the procedure that most often causes it. Average erectile function is stable, long-term outcomes match TURP, and early dips usually recover through the first year.

The genuine cost is ejaculation, and men who have normal erections now should hear that their individual risk of erectile change — while small — is not zero.

The conversation worth having is not "will I get ED?" It is "given my current erections, my prostate size, how badly I am sleeping, and how much ejaculation matters to me, which of these operations fits?" That question has a good answer. The first one does not.
