Latest FAQs

Can I come for consultation and operation on the same day?show

Yes. There is a small chance that we find something that makes reversal unlikely to succeed or dangerous at the pre-op examination. We will gather as much information about you over the phone to give you the best advice we can as to the likely outcome. The usual deposit paid to book an operation date will  cover the very unlikely chance that we don’t advise proceeding on the day.

What different types of microsurgery are there?show

Many, but principally Single, double and multilayer vasovasostomy. We perform the Microdot Multilayer Microsurgical vasovasostomy (MMMV). The layers referred to are the structures forming the vas. So from the inside out the layers are 1.skin lining the inner sperm tube of the vas (lumen) 2. Muscle, (involuntary), forming the thick wall of the vas and 3. Connective tissue, including blood vessels, on the outside of the vas.We use extremely fine microsutures (10-0 & 9-0) used in eye surgery. These fine sutures and the needle which are barely visible to naked eye, help to achive good approximation with minimal trauma to vas.

By approximating the cut ends of the vas in three layes, there is better chance of achieving a leak proof joining of the cut ends of the vas.

Will I be asleep during the procedure?show

Yes. The sedation is so relaxing that you will drift off to sleep. We keep the level of sedation "topped-up" until the operation is finished at which time you will gradually wake up without any of the general anaesthetic problems (such as nausea etc.). Long acting local anaesthetic is used to completely numb the operating area. This straightforward sedation and local anaesthetic has been proven to be very much safer than GA.

Which sutures do you use?show

We use special vasovasostomy sutures specifically manufactured for this operation by Sharpoint in the USA, size 10-0 for the inner layer and 9-0 for the outer two layers. These sutures aer very expensive and they are the best for the vsectomy reversals.

In many other places they use 6-0 nylon which has a much larger needle and thicker sutures.Larger the needle and thicker the suture, more trauma to the delicate tubes (vas)

Will I feel unwell after the anaesthetic?show

NO! Unlike General Anaesthesia. The only effects are forgetfulness and clumsiness. Many men find the sedation very relaxing, "the best sleep i’ve had in months"!

How long does the op take?show

From 2 hours to 4 hours. Fortunately for the patient this feels just like a few minutes.There is no painful effects of having a tube or laryngeal mask put in the throat required in  the general anaesthetic. 

When can I go home?show

Good question. For many people the answer is "within weeks". Many of our couples have become pregnant within 3 months! In general the longer the vasectomy has been done the longer it may take to return to fertility.

Could there be complications?show

Yes, but fortunately only the same sort of complications that can arise during the vasectomy itself, ie swelling. Swelling can be either early (day 1-3) or later day (5-10. Early swelling is due to haematoma, ie internal bruising or bleeding ( chance2-3%), late swelling is due to infection (much less than 1%). Fortunately elective surgery centres such as ours do not attract patients prone to hospital acquired infections.

Will it be painful afterwards?show

No! Our patients score the post op discomfort at around 2 out of 10. This is because we have not disturbed the tissues to any great extent, we lift the vas above the skin, repair it and return it with no trauma to the testis. Occasionally we may have to open the coverings of the testis to deal with difficult situations and challenges regarding the qulaity and length of vas.

Shall I bring pain killers?show

No! We send you home with the only pain killers you will could possibly need, Paracetamol and Ibuprofen.

Can I come on my own?show

By law we must discharge you to the care of a responsible adult. If absolutely necessary you get accompanied by an adult since you will have sedation.Unless you have the procedure fully  under the local anaesthetic without sedation, you need to have an adult with you to be dischrged home.

When can I have sex again?show

Not before 21 days post op. And this applies to ejaculation not just sex. The reason is that ejaculation pressurises the fluid in the vas which can force it’s way out through the unhealed join causing scarring and narrowing of the join.

What do I do about tests afterwards?show

We recommend semen tests at 2 monthly intervals after the op. We will give the request forms to have this arranged  through the GP or through a fertility clinic. The cost of doing the test  will have to be paid  by you as our procedure cost does not include this cost. It would be unfair to include this cost as many of our  patients come from distant places and they will not be able to avail the facility of sending the samples to our local lab..

I’ve had a reversal before, is it worth having it done again?show

Yes, almost always. The most common problem with reversal surgery is the formation of scar tissue at the junction. Removal of the scarred tube and microsurgically re-joining the vas is highly effective. We advise prior assessment and consultation here at the clinic.

I’ve had IVF before, is it now worthwhile having a reversal?show

Certainly, yes. Your chances may be reduced slightly below the average if you have undergone PESA sperm extraction. 

Will I know if the op is going to be successful on the day?show

Yes, because we will know the result of the sperm test done during the op and that the connection was successful. With a positive finding of sperms in the vas fluid your chances of returning to fertility are above 90%.

Will sex be any different after the reversal?show

We hope so. Most men report some change for the better.

Should I have sperm freezing after reversal?show

Yes, definitely. There is a chance that after some time, possibly from 6 months onwards that some narrowing of the junction may occur. We suspect that certain factors such as subtle damage inflicted on the vas by diathermy may make scarring more likely. We do not have definite statistics on this but estimate the chances of scarring being 30% over 5 years.

We want a baby in 2 years time. Should we delay the reversal?show

If you do, you risk developing blow out if you don’t you may have scarring. Scarring is treatable (by re-operation) whereas blow out is not. So on balance have it done now and have some sperm frozen. Or, change the plans, throw caution to the wind and have that family now!

My wife is 40+. Is it too late?show

Probably not. After vasectomy reversals,  pregnancies do happen where the wife is 40 plus. The classic way of determining whether or not it is too late is to have the FSH blood test at day 0-3 of the menstrual cycle. If the  level is within the normal range for your lab, then it shows that the woman may be still fertile.However there is steady decline in the pregnancy rate with increase in the age of the female partner.You may also wish to get some advice on the IVF option if your partner is older than 40 and you and your partner are considering to have only one child. 


I am age 50+. Am I too old to become a dad again?show

No, not too old at all. Men only very rarely slow down their sperm production. 

How much does the operation cost?show

 We operate straightforward fixed fee pricing.

We prefer to work on a fixed fee basis so you know exactly how much you are going to pay and that there are be NO extra charges, ever.
Our current fees are;

  • Consultation is £150 ( face to  face consultation if required. This fee will be reduced from the procedure fee if choose to have the procedure with us.
  • Vasectomy reversal £2450.
  • Re-do vasectomy reversal £2700.

Full terms and conditions of the fee will be provided prior to booking a date for the procedure.

Is there any increased risk of an abnormal child after vasectomy?show

No, just the standard, routine chance unlike IVF babies over whom there are questions over their long term health.

What is the waiting list?show

We can arrange a consultation within a week or two, almost any day of the week. Time to surgery is from 1-3 months. But we sometimes have operation slots at short notice, so give Barbara a call.

I’ve got medical problems; can I still have a reversal?show

Probably yes, but tell us all about your medical history and most importantly tell us all the medication you take. We will want to see you for consultation and discuss the matter then. Any medication that thins the blood such as Aspirin or warfarin is especially important and should be stopped 7 days before surgery.

What if reversal doesn’t work?show

Two possibilities. Either elect to have IVF or redo-reversal by vaso-vasostomy or vaso-epidydimostomy in selected situations

I have seen a clinic that advertises microsurgery.show

He does about 30-50 cases per year, is a general urologist and he is less expensive than you, should I go there?

Do not even contemplate having a reversal with a surgeon who does not use microsurgery (some use "loupes" which magnify 2-3 times – it is just not good enough. The operating microscope magnifies up to 25 times and we often use all that power). If the surgeon gets the operating microscope out just once a week he is unlikely be proficient and confident as it takes repeated practice and familiarity to be competent and accurate with this little practice.
