Nerve-sparing RPLND and ejaculation | CION Cancer Clinics
The nerves that make ejaculation happen run straight through the area an RPLND clears. Nerve-sparing means the surgeon finds and protects them, so that most men keep normal ejaculation. Without it, semen usually flows backwards into the bladder, which is harmless but affects fertility. Erections and orgasm are controlled by different nerves and are not changed by the operation. This page explains how sparing is done, when it is not possible, and what to ask. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What does nerve-sparing RPLND mean for ejaculation?
The nerves that make ejaculation happen run straight through the area an RPLND clears. Nerve-sparing means the surgeon finds those nerves and works around them, so that most men keep normal ejaculation after the operation. Without nerve-sparing, semen usually flows backwards into the bladder at orgasm instead of out, which is called retrograde ejaculation. Erections and orgasm are controlled by different nerves and are not affected by the operation.
Which nerves, and where they run
They are part of the sympathetic nervous system, the same system that speeds your heart when you are startled. They run down either side of the spine, then cross in front of the aorta just below where it splits towards the legs. That crossing point sits inside the field of almost every RPLND, which is why the risk exists at all.
What they actually do
At orgasm these nerves close the neck of the bladder and squeeze semen forward. If they are cut, the bladder neck stays open, the squeeze happens, and the semen takes the easier route backwards. The sensation of orgasm is unchanged. What is missing is the fluid.
Four separate things
What the operation can affect, and what it cannot
Families often run all of these together as "sexual function". They are separate, and the operation only touches one.
Ejaculation
The one thing at risk. Nerve-sparing protects it in most men. Where sparing is not possible, semen usually goes backwards into the bladder and comes out later with urine, which is harmless but means no fluid at orgasm.
Erections
Not affected by RPLND. The nerves for erection sit low in the pelvis, well away from the operation. If erections change after surgery, the cause is usually tiredness, low mood or worry, all of which are treatable.
Orgasm
Not affected. The feeling of climax comes from nerves and brain pathways the operation does not touch. Men with retrograde ejaculation describe a normal orgasm with no fluid, sometimes called a dry orgasm.
Fertility
Sperm are still made by the remaining testicle. If ejaculation is retrograde, they end up in the bladder rather than out, so natural conception becomes difficult. Sperm can be collected from urine or from the testicle for fertility treatment.
Banking sperm before surgery keeps this simple whatever happens.Not sure whether this applies to you?

How the surgeon protects the nerves
Finding them first
Before the nodes are touched, the surgeon looks for the nerve chains alongside the spine and the fine branches crossing the aorta. They are thin and pale and easy to lose in fatty tissue.
Tracing and marking
Each nerve is followed and gently lifted away on a soft loop, so it stays visible throughout the dissection rather than being found only after it has been cut.
Clearing around them
The node-bearing tissue is then taken off the vessels around the nerves, working in the gaps between them. This takes longer than a straightforward clearance.
Deciding when to stop sparing
If a mass is wrapped around a nerve, the surgeon has to choose. Removing the cancer completely comes first. That is the honest limit of nerve-sparing, and it is decided on the table, not beforehand.

Being straight with you
Who nerve-sparing does not suit, and what this page cannot tell you
Nerve-sparing works well when the nodes are small and have not been treated. It is much harder after chemotherapy, because scar tissue binds the mass to the vessels and hides the nerves. And it is set aside altogether when a mass has grown around the nerves, because leaving cancer behind to protect ejaculation is not a trade any surgeon should make.
What to ask before the operation
Ask whether nerve-sparing is planned for you. Ask what would make the surgeon abandon it during the operation. Ask whether they will try to spare one side if both cannot be saved. And ask, plainly, how often it succeeds in their hands for cases like yours. A surgeon who answers those four questions directly is one you can trust with the fifth.
What this page cannot tell you
It cannot tell you whether your nerves can be spared. That depends on your scan, on what chemotherapy has left, and on what the surgeon finds once the abdomen is open. It also cannot tell you how ejaculation will be afterwards. Some men recover function slowly over months even when the surgeon was unsure. Ask your team what they expect in your case, and ask again after the operation.
Commonly believed
Four things men tell us, and what is actually true
"The operation will make me impotent."
RPLND does not affect erections. The nerves for erection are in the pelvis, far below the operation. What can change is ejaculation, which is a different thing. Many men are not told the difference and carry this fear for no reason.
"Retrograde ejaculation means no orgasm."
Orgasm is unchanged. The sensation happens as before. What changes is that little or no fluid comes out, because it has gone into the bladder. Some men notice cloudy urine afterwards, which is the semen leaving harmlessly.
"Nerve-sparing is a special technique only some hospitals have."
It is a way of doing the standard operation, not a separate machine or licence. Whether it is offered depends on the surgeon's experience and on your case. Ask your centre directly whether they plan to spare the nerves and how often they manage it.
"If the nerves are cut, nothing can be done about children."
Sperm are still produced. They can be collected from urine after orgasm or directly from the testicle and used in fertility treatment. Banking sperm before surgery is simpler than any of that, which is why it should be discussed before the date is set.
On your notes
Words you will see, in plain language
- Sympathetic chain
- The line of nerves running down each side of the spine. The ejaculation nerves branch from it.
- Hypogastric plexus
- The web of nerves in front of the lower aorta where the branches from both sides meet and head for the bladder.
- Antegrade ejaculation
- Normal, forward ejaculation. What nerve-sparing aims to keep.
- Retrograde ejaculation
- Semen flowing backwards into the bladder at orgasm. Harmless, but it affects fertility.
- Unilateral nerve-sparing
- Sparing the nerves on one side only. Often enough to keep forward ejaculation.
Questions we are asked
Common questions about nerve-sparing RPLND
Will I know straight after surgery whether it worked?
Not immediately. You will not be thinking about it in the first weeks, and nerves that were handled can take time to settle. Some men who have no ejaculation at first regain it over the following months. Your team will ask about it at follow-up, and you should raise it if they do not.
Can the nerves be spared in a post-chemotherapy operation?
Sometimes, especially when the leftover mass is small and sits on one side. It is harder than in a primary operation because of scarring. Ask your surgeon whether they will attempt it and what they expect; the answer depends on your scan, not on a general rule.
Is nerve-sparing less safe for the cancer?
Not when it is done in the right cases. The nodes are still removed completely; the surgeon simply works around the nerves rather than through them. Where the cancer is wrapped around a nerve, sparing is abandoned so nothing is left behind. Clearing the cancer always comes first.
Should I bank sperm even if nerve-sparing is planned?
It is sensible to discuss it. Sparing is planned, not promised, and the decision to abandon it is sometimes made during the operation. If you have had chemotherapy, sperm counts may already be low. Banking beforehand removes the worry from the operation entirely.
Does keyhole or robotic surgery spare the nerves better?
The magnified view can help the surgeon see the nerves, but what matters most is the case and the surgeon's experience. A large mass is usually done open whatever the approach elsewhere. Ask your centre what they recommend for you rather than choosing by method.
My ejaculation is weak but not absent. Is that retrograde?
It may be partial retrograde ejaculation, where some semen goes forward and some back, or it may be an early stage of recovery. A simple urine test after orgasm shows whether sperm are going into the bladder. Tell your team; it is a common and easily checked question.
Will it affect my marriage or my sex life?
Erections, desire and orgasm are unchanged, so most couples find sex itself is much as before once recovery is complete. The change is the absence of fluid, which some men find upsetting at first. Talking about it with your partner before surgery helps, and a counsellor can sit with you both.
Who do I ask about this without embarrassment?
Your surgeon, directly, and before the operation. They have this conversation with every man who has this surgery, and the question is expected. If it is easier, write it down and hand it over, or call the helpline and ask us to raise it with the team on your behalf.
