Pregnancy after a vasectomy: the options
Part of our guide to IVF treatment in Goa.
A vasectomy blocks the two tubes (the vas deferens) that carry sperm up from the testes, so the semen no longer contains sperm. The testes go on making sperm all the same. For a pregnancy afterwards there are two routes: collecting sperm directly with a fine needle, by PESA or TESA, and using them for IVF with ICSI; or an operation to rejoin the tubes, a vasectomy reversal, so that sperm return to the semen. At Heartbeats IVF in Goa we explain both, so that the two of you can choose.
A vasectomy is meant to be permanent, yet circumstances shift: remarriage, a child lost, or the hope of a bigger family. The decision rests on the wife as much as on the husband. Her age and egg reserve often decide which route makes more sense, so both partners are seen at the first visit.
Are sperm still made after a vasectomy?
Yes. A vasectomy closes the tubes but leaves the testes working, so sperm go on being made and are quietly absorbed by the body. This is why sperm can usually be collected, even many years after a vasectomy. Two changes do build up with time. Pressure behind the block can cause a second blockage further back, in the coiled tube behind the testis (the epididymis), and some men make antibodies against their own sperm. Both matter more for a reversal than for collecting sperm with ICSI.
How are sperm collected after a vasectomy?
- PESA, short for percutaneous epididymal sperm aspiration. Through the skin of the scrotum, a thin needle reaches the epididymis, where sperm collect behind the block, and a little fluid is drawn off. Local anaesthesia or light sedation is used.
- TESA, short for testicular sperm aspiration. If the epididymis yields too few sperm, or is scarred, the needle draws a small amount of tissue from the testis instead, where sperm are being made.
Each takes well under an hour, and the husband usually leaves within a few hours, a little sore for a day or two. The embryologist searches the sample under the microscope straight away. Sperm can be used in the same cycle, with the collection timed for the day of the wife's egg collection, or frozen for a later cycle; your doctor advises which suits you. Heartbeats IVF carries out surgical sperm retrieval in Goa, and the sample passes directly to our embryology laboratory.
A needle sample holds too few sperm for IUI or standard IVF, so it is always used for ICSI treatment, where each mature egg receives one sperm, injected by the embryologist. Larger operations such as micro-TESE are rarely needed after a vasectomy; they belong to men whose testes make very few sperm, explained in our guide to azoospermia treatment. If no usable sperm are found, the choices that remain are explained before anything else is decided. Donor sperm, when chosen, comes only from a registered ART bank.
What does a vasectomy reversal involve?
A reversal is a microsurgical operation, usually under general or spinal anaesthesia. Using an operating microscope, the surgeon rejoins the two cut ends of each vas deferens. If there is a second blockage in the epididymis, the vas is joined to the epididymis instead, a finer and longer operation. It is done by urologists trained in microsurgery.
Sperm usually take some months to return to the semen, with semen checks every few months to follow progress. A natural pregnancy can then take many months more, and sometimes sperm do not return at all. The longer it has been since the vasectomy, the less likely a reversal is to bring sperm back. If a reversal could be right for you, your doctor goes through the operation with you, along with the questions worth putting to the surgeon.
Sperm retrieval with ICSI or reversal: how do they compare?
- The wife's age and egg reserve. When she is in her late thirties or her egg reserve is low, time matters most. Retrieval with ICSI gives a chance within weeks; after a reversal the couple waits for sperm to return, then tries month by month.
- Years since the vasectomy. A reversal works less well as the years pass. Collecting sperm by needle depends far less on the time since the vasectomy.
- The wife's own fertility. If she has blocked tubes, endometriosis or another reason to need IVF anyway, retrieval with ICSI treats both problems in one cycle.
- How many children you hope for. If sperm come back after a reversal, further children can be conceived without more treatment. With ICSI, each child needs a treatment cycle, though extra embryos from one cycle can be stored through embryo freezing and transferred later.
- Who goes through treatment. A reversal is an operation for the husband only. Retrieval is short for him, but IVF means injections and an egg collection for the wife.
- Contraception afterwards. After a reversal that works, contraception is needed again. After retrieval with ICSI, the vasectomy keeps working.
Which tests does each partner need first?
- For the husband. An examination, and a semen analysis to confirm that there are still no sperm. Hormone tests are added if the testes are small or the history suggests another cause. Our guide to the male fertility test explains each of them.
- For the wife. An AMH blood test and a scan of the ovaries to see the egg reserve, and a check of the womb and tubes when the history calls for it.
Is a vasectomy passed on to a child conceived this way?
No. A vasectomy is a blockage made by an operation, not an inherited condition, so a son conceived with ICSI does not inherit it. This is different from azoospermia with a genetic cause, where genetic tests and counselling come first. The usual checks of any IVF pregnancy still apply.
What does it cost?
Sperm retrieval is billed on its own, apart from the fixed price of IVF with ICSI, and its fee is told to you in advance. Our page on IVF and ICSI costs in Goa lists what each price includes, with the date of the price list.
What should the two of you bring to the first visit?
For the husband: the year of the vasectomy and any papers from it, every semen report done since, and a list of the medicines he takes. For the wife: her reports, especially any AMH, hormone or scan reports. Other causes of male infertility, and how each is treated, are covered in our guide to treating male infertility.

Questions couples ask about pregnancy after a vasectomy
Can sperm still be found many years after a vasectomy?
Usually, yes. The testes keep making sperm after a vasectomy, so PESA or TESA can find sperm even when the vasectomy was done long ago. The time since the vasectomy matters much more for a reversal.
Is PESA or TESA painful?
It is done under local anaesthesia or light sedation, so the procedure itself should not hurt. Soreness for a day or two is usual, and he can leave within a few hours.
Can sperm collected by needle be used for IUI?
No. A needle sample holds far too few sperm for IUI. The sperm are used for IVF with ICSI, where one sperm is placed directly inside each mature egg.
How soon after a vasectomy reversal do sperm come back?
Usually within some months, but it can take longer, and in some men sperm do not return. The semen is tested every few months after the operation to see how it is going.
Does a vasectomy reversal always work?
No. Whether sperm return depends on how long ago the vasectomy was done, how the tubes heal, and whether there is a second blockage. Nobody can promise the result beforehand, and a pregnancy also depends on the wife's fertility.
Do both partners need to come to the first visit?
Yes, if possible. The wife's age and reports shape the choice as much as the husband's, so seeing both of you together often saves a second visit.
