A vasectomy takes about fifteen minutes at most Dutch clinics, cost around 495 euro at Andros in 2026, and does not make you infertile until roughly three months later. That last part is the part men skip.
The procedure is small. The decision is not.
Here is what strikes me about almost every Dutch page on male sterilisation: it was written by the party that performs the procedure. We do not perform vasectomies. What follows is what happens, what the research says about it, and which questions are worth taking into the consultation.
What is a vasectomy exactly?
A vasectomy is a small procedure in which a doctor cuts and seals both vas deferens. Sperm cells can no longer reach your semen after that. Your testicles carry on producing sperm and hormones, those cells simply no longer leave the building.
The formal name is male sterilisation. In the consulting room you will hear vasectomy.
Your vas deferens is a tube of roughly 30 to 40 centimetres running from the epididymis to the prostate. A section is removed, and both ends are tied off or sealed shut.
Sperm cells make up only a few percent of your semen. The rest comes from the seminal vesicles and the prostate, and neither is touched. That is why the volume barely changes. Thuisarts.nl, the patient site of the Dutch College of General Practitioners (NHG), puts it plainly: nothing changes about ejaculating.
The sperm you keep producing is simply broken down by your body. That happens on its own, every day, without you noticing.
How does the procedure go?
You get a local anaesthetic in the scrotum. The doctor locates the vas deferens, makes a small opening in the skin, divides the tube and seals both ends. Then the same on the other side. Andros puts this at about 15 minutes, Thuisarts allows half an hour.
You are awake, and you walk out on your own legs.
There are two routes to the same tube. In the classic method the doctor makes a small cut on each side with a scalpel. In the no-scalpel technique the doctor punctures the skin with a sharp clamp and stretches the opening, without cutting.
That difference sounds like a detail. It is not.
In a 2020 meta-analysis, the share of men reporting pain afterwards was 24 percent with the scalpel method, against 7 percent with the no-scalpel technique (PMID 32164161). Which method a clinic uses is therefore a fair question to ask up front.
I would ask it. It costs you one sentence on the phone.
How long does recovery after a vasectomy take?
Most men are back on their feet within a few days. Thuisarts advises one to two days off work, a week without heavy lifting or cycling, and five days without sex. Paracetamol is usually enough for the soreness, and the wounds should stay dry for two days.
Tight underwear in the first few days helps too, according to the same source.
What men mention most often afterwards is not pain but a heavy, congested feeling in the scrotum that builds in the first weeks and then fades. That fits the picture and usually settles on its own.
The day-by-day version, including the point where something stops being normal, is in recovery time after male sterilisation.
When are you actually infertile after a vasectomy?
Not immediately. Sperm cells still sit in the tubes beyond the block, and those have to clear first. Thuisarts describes two to three months before no sperm cells remain, and contraception continues until then. Andros adds a floor of roughly 30 ejaculations.
Confirmation comes from a semen sample, not from a feeling.
After about three months you hand in a sample at the laboratory, and it is examined under a microscope for live sperm cells. Sometimes a second check is needed.
That route runs through the clinic that performed the procedure. We do not run that check, and a blood test cannot replace it. Sperm cells show up in semen, not in blood. What such a result looks like is covered in semen analysis values.
The months between the procedure and that result are the riskiest stretch of the whole thing. You feel finished, and you are not.
Does a vasectomy change your testosterone or your sex drive?
According to the available research, no. Your vas deferens transports sperm, not hormones. Testosterone is made in the Leydig cells of your testicles and goes straight into your bloodstream, along a route a vasectomy never touches.
That is the anatomy. The research points the same way.
A Chinese study of 437 men aged 40 and over compared 232 vasectomised men with 205 who were not. After adjustment for the usual confounders, there were no statistically significant differences in testosterone, SHBG or LH (PMID 29658249).
The literature on sexual function is smaller, but consistent. Among 64 men followed with the IIEF questionnaire, scores for desire and satisfaction rose slightly after the procedure, and no case of surgery-related erectile dysfunction was seen (PMID 16255791).
| What men fear | What the research shows | Source |
|---|---|---|
| My testosterone will drop | No significant difference after adjustment, in 437 men aged 40 plus | PMID 29658249 |
| I will lose my sex drive | Desire and satisfaction rose slightly on an IIEF measure | PMID 16255791 |
| I will get erection problems | Not one case caused by the procedure in that same group | PMID 16255791 |
| Almost nothing will come out | Sperm is a few percent of the volume, the rest remains | Thuisarts |
| It will give me prostate cancer | No association with aggressive or fatal prostate cancer | PMID 28715534 |
That last row deserves a footnote, and it sits in the spoke on long-term disadvantages.
So if you feel flat after your sterilisation, with less interest and a shorter fuse, the research does not point at the procedure. Something else is going on, and that is the part you can actually measure. Some men map their hormones with the Hormones Man panel or the testosterone panel. Always discuss an abnormal result with your GP.
Which other signals belong to that picture is covered in low testosterone in men. How testosterone and libido relate is explained in libido and testosterone.
Which complications actually occur?
Bruising and infection top the list, and in large series both stay under two percent. The most usable figures come from a British audit that followed 105,393 vasectomies prospectively and published a percentage per complication (PMID 38989696).
That is not an estimate from a leaflet. That is counted.
| Complication | How often, in 105,393 procedures | Roughly |
|---|---|---|
| Haematoma in the scrotum | 1.56 percent | 1 in 64 |
| Wound infection | 1.22 percent | 1 in 82 |
| Early failure | 0.93 percent | 1 in 108 |
| Persistent pain complaints | 0.14 percent | 1 in 714 |
| Late failure | 0.04 percent | 1 in 2,500 |
That fourth row is the single most contested number in this whole topic. A 2020 meta-analysis lands on 5 percent instead of 0.14 percent (PMID 32164161), a factor of 35.
Both figures are real. They simply do not measure the same thing, and why that is gets unpicked in pain after sterilisation.
Persistent pain after the procedure is not the only explanation for a nagging scrotum, by the way. Epididymitis or a varicocele gives a comparable feeling, and both occur in men who were never sterilised.
Can a vasectomy fail?
Yes, and it is rare. Thuisarts puts it in usable terms: of 1,000 couples where the man has been sterilised, fewer than 5 get pregnant per year. In the British audit above, 0.04 percent were late failures, meaning after an earlier clear check.
The vas deferens can, in rare cases, grow back together.
That is called recanalisation, and Andros quotes a chance of 1 to 3 per 1,000. Early failure is something else: sperm is still found after three months, and that occurs in almost 1 in 100 men in the audit.
Say you are 39, you were sterilised in April and you hand in your sample in July. The result is clear. The chance you later cause a pregnancy anyway sits in the order of 1 in 2,500. No contraception sits at zero, including this one.
To me that is the honest answer: extremely reliable, not absolute.
Can a vasectomy be reversed?
Sometimes, and you should not count on it. The repair operation is called a vasovasostomy, in which a microsurgeon reconnects the vas deferens. Whether sperm returns to your semen afterwards depends heavily on how many years sit in between.
Thuisarts is brief about it: men usually stay less fertile.
The classic figures come from the Vasovasostomy Study Group, which analysed 1,469 reversals. Within 3 years, sperm returned in 97 percent and 76 percent of couples conceived. At 15 years or longer it was 71 percent and 30 percent (PMID 1997700).
Those two columns do not move together, and that is the whole point. The full breakdown is in reversing a vasectomy.
So treat a vasectomy as permanent. If that sentence makes you uncomfortable, that is information in itself.
What does a vasectomy cost in the Netherlands?
Budget roughly 350 to 500 euro, and no reimbursement from your basic insurance. Sterilisation is not in it, for anyone. Andros listed a 2026 rate of 495 euro, and Consumentenbond uses about 500 euro as a guide figure.
Supplementary insurance may pay part of it back.
How much varies sharply by policy: some packages reimburse 100 percent, others cap at 300 or 400 euro. The full comparison, including the cost per year of use, is in vasectomy costs.
Sterilisation for him or for her?
Medically, the male procedure is the smaller of the two. A vasectomy happens under local anaesthetic in a quarter of an hour. Female sterilisation is keyhole surgery in the abdomen, usually under general anaesthetic, and costs 1,300 to 1,600 euro according to Consumentenbond.
That is three times the money and a multiple of the recovery time.
Couples do not decide on those numbers alone, and rightly so. Who carries the wish for children, who has been through a pregnancy already, and how settled the relationship feels all weigh in.
But if the conversation at your kitchen table is only about her while the smaller procedure sits with you, that is worth raising.
When is a vasectomy not a good idea?
When you are unsure. That sounds glib, but it is the one factor no number can outweigh. The procedure carries few complications, and regret afterwards is the problem that repairs worst.
Young age, a short relationship, and a recent break-up or birth are the circumstances in which that doubt most often resurfaces later.
There is no legal age limit in the Netherlands, but clinics tend to ask more questions of young men without children. That is not paternalism. That is precisely what their experience is for.
Talk it through with your partner, and take the time the procedure itself does not ask for. And if your fertility is a question mark to begin with, start at male fertility rather than at a decision you do not undo.
Still unsure? Then book a conversation, not an appointment.
