Vasectomy reversal or sperm retrieval with IVF?

Written by Mr Maj Shabbir FRCS(Urol), Consultant Urological Surgeon & Andrologist · 22 October 2026

If you have had a vasectomy and now want a child, there are two routes. A microsurgical vasectomy reversal rejoins the vas deferens so that sperm can return to the ejaculate and you can conceive naturally. Surgical sperm retrieval collects sperm directly from the epididymis or the testicle, and those sperm are then injected directly into your partner’s eggs in the laboratory using ICSI, a form of IVF. Both are reasonable choices. Which one suits you depends on a handful of factors, several of which concern your partner as much as you, and I set both out honestly rather than steering you towards one operation.

Is vasectomy reversal better than sperm retrieval with ICSI?

Neither is better for every couple: the right route depends mainly on your partner’s age and fertility, the years since your vasectomy and how many children you hope to have.

The British Association of Urological Surgeons (BAUS) offers a useful rule of thumb. Its patient leaflet says that, in general terms, if your vasectomy was performed less than 20 years ago, your current partner is less than 35 years old and you wish to have more than one child, vasectomy reversal is a better approach. When one or more of those conditions does not apply, the balance shifts, and the factors below decide it.

It is also worth being clear about what neither route can promise. The NHS puts it plainly: it may be possible to reverse a vasectomy, but this does not always work. Assisted conception carries no guarantee either. BAUS gives an average success rate for assisted conception of between 30% and 40%, and notes that your partner’s age and health also affect it.

How much does my partner’s age affect the choice?

Often more than anything about you: the female partner’s age and ovarian reserve are frequently the strongest predictor of whether a reversal leads to a pregnancy.

BAUS states that the chance of a pregnancy after reversal is directly related to two things: the time since the vasectomy and the age of your current partner. The reason is simple. A reversal restores sperm; it does nothing for your partner’s fertility. A technically perfect operation that brings sperm back into the ejaculate may still not lead to a pregnancy if her own fertility is limited.

Time is the other issue. A reversal is the slower route to a first attempt, because you have to wait for sperm to reappear before you can start trying. Where your partner’s age makes time critical, or where she has fertility factors of her own, sperm retrieval with ICSI is often the more sensible choice. Her age affects that route too, which is why the BAUS figure for assisted conception above carries the same caveat.

Does the time since my vasectomy change the answer?

Yes: the longer ago your vasectomy, the lower the chance that sperm return and that a pregnancy follows, and the more likely a more complex join will be needed.

The BAUS figures show the size of the change. When a reversal is done less than three years after a vasectomy, BAUS quotes sperm returning in 97% of men and a pregnancy rate of 75%. At 20 years or more, those figures fall to 40% and less than 10%. The bands in between, and how to read them for your own situation, are set out in my guide to vasectomy reversal success rates.

Part of the reason is mechanical. Over the years, back-pressure can cause a second blockage in the epididymis, and the vas then has to be joined directly to the epididymis rather than to its other cut end. That is a considerably more demanding operation, and whether it is needed is only decided during surgery. There is no absolute cut-off, though: successful reversals are performed well over fifteen years after vasectomy.

Sperm retrieval is affected differently. Your testicles carry on producing sperm normally after a vasectomy, so retrieval does not depend on rejoining anything. That is why a very long interval tends to tip the balance towards retrieval with ICSI.

What if we want more than one child?

A reversal that works lets you try for later children naturally, without further treatment; with sperm retrieval, every pregnancy needs further fertility treatment.

For couples hoping for a larger family, this can outweigh everything else. Once sperm are back in the ejaculate, each further pregnancy can happen at home, on your own timetable. With retrieval, each attempt goes through your fertility unit. If sperm from the retrieval were frozen, they can be used later without another operation; if none were stored, a further retrieval would be needed.

A reversal is not necessarily permanent, though. The join can scar and close months or years after it first worked, which is known as late failure. For that reason, sperm freezing at the time of the reversal is often offered as insurance, so that ICSI remains available later without further surgery.

Which route gets us to a pregnancy sooner?

Retrieval with ICSI does not wait for sperm to reappear, so it usually reaches a first attempt sooner; a reversal starts slower but then allows natural conception.

After a reversal, I arrange a semen analysis around three months after surgery and repeat it periodically. Sperm can take several months to reappear after a direct rejoin, and sometimes twelve months or more after a join to the epididymis. A single early negative result does not mean the operation has failed, but when your partner’s age makes time critical, that wait matters.

With retrieval, the timing is planned with your fertility unit. Sperm can be retrieved on the day of your partner’s egg collection and used fresh, or retrieved beforehand and frozen. Freezing first means your partner does not start stimulation before you know sperm are available, although after a vasectomy, when the blockage rather than sperm production is the problem, sperm can almost always be obtained.

What does each option involve for each of us?

A reversal means a longer operation for you and no procedure for your partner; retrieval is a smaller procedure for you but means IVF treatment for her.

A reversal is done under general anaesthetic, usually as a day case, and takes two to four hours. Expect swelling, bruising and discomfort for one to two weeks. Most men return to desk work within a week, and to physical work, sport, cycling and heavy lifting at around four weeks. The risks include bleeding and scrotal haematoma, infection, chronic scrotal pain, sperm granuloma and late failure. Your partner needs no procedure at all.

After a vasectomy, sperm retrieval is usually a needle technique, aspirating sperm from the epididymis (PESA) or the testicle (TESA) through the scrotal skin, rather than microTESE, which is designed for men whose testicles make very little sperm. The NHS notes that surgical sperm extraction is usually done under local anaesthetic, but may be done under general anaesthetic depending on the procedure. My guide to microTESE, TESA and PESA compares the techniques. Because the numbers of sperm retrieved are usually low, successful treatment is only likely with ICSI, so your partner goes through ovarian stimulation and egg collection.

How much does a vasectomy reversal cost compared with sperm retrieval and ICSI?

I do not publish surgical prices, because the total depends on what is needed; once a plan is agreed at consultation, you receive a written quotation before anything is booked.

What I can explain is how the costs are structured, because the two routes differ. A reversal is essentially one operation: a surgeon’s fee, an anaesthetist’s fee and hospital charges for a day-case procedure, which the quotation sets out separately. Follow-up semen analyses are billed by the hospital, and sperm freezing at the time of the reversal, if you choose it, adds laboratory processing and storage.

Retrieval with ICSI has two parts. The retrieval itself carries surgical, anaesthetic and facility costs, plus processing and freezing of the sperm. The ICSI cycle, covering your partner’s stimulation, egg collection and the laboratory work, is arranged through your fertility unit. If you want more than one child, the cost of a reversal is largely incurred once, whereas the costs of fertility treatment recur with each attempt.

A first consultation with me is £350 in person or £300 by video or telephone, and a follow-up is £250. If you have private medical insurance, check your policy before assuming either route is covered. More detail is on my fees and insurance page.

Can we still have IVF if a vasectomy reversal does not work?

Yes. Choosing a reversal first does not close the door on ICSI: sperm retrieval remains available if sperm do not return or the join later fails.

The NHS lists surgical sperm extraction as an option for men who have had a vasectomy or a failed vasectomy reversal. If sperm were frozen at the time of your reversal, you may not need another operation at all. A repeat reversal is also reasonable in selected men. Whichever applies, the fallback plan is agreed before the first operation, so that you know in advance how long you will wait for sperm and what you will do if they do not appear.

How do we decide which route is right for us?

Start with a proper assessment of both of you, then weigh your partner’s age, the interval since your vasectomy, your family plans and your budget together.

At consultation I go through the date and type of your vasectomy, any previous reversal, your general health, your partner’s age and fertility history, and what you are hoping for. I examine you to identify the vas on both sides, check for a sperm granuloma and assess the testicles and epididymis. Your partner is welcome to come, and I liaise directly with fertility units where a joint decision is needed. Deciding not to pursue treatment is also a legitimate outcome of that conversation. If you would like to talk it through, you can arrange a consultation.
