It is a safe and minimally-invasive technique with a much lower percentage of complications in comparison to a conventional vasectomy

The method

The no scalpel vasectomy is the best surgical method in order to achieve easy, cheap, quick, painless, effective and permanent contraception without stitches or complications. It consists of occluding the vas deferens using clamps that were specially designed in China, which make the operation much safer and simpler. The no scalpel vasectomy was first introduced in Europe in 1994 by Dr Philip Li.

Subsequently, a needle-free instrument for injecting anaesthetic was developed (MadaJet), which allows the anaesthetic for the vasectomy to be administered without the need for needles. The no needle no scalpel vasectomy was introduced in Europe in 2005 by Dr Doug Stein.

Instructions before the vasectomy

  • There is no need to come on an empty stomach, although we do recommend having a light breakfast, consisting of liquids only. There is no need for a prior blood test, except for in special cases.
  • Shave your scrotum and the base of your penis 24-48h before surgery. There is no need to shave your pubic hair. It is best to shave in a hot bathroom with a razor blade and shaving cream. Hair removal creams are not advisable as they occasionally cause adverse reactions that mean the operation must be postponed. Do not use an electric shaver either. On the two days prior to the operation, wash the scrotum area with plenty of antiseptic soap (such as Germisdin®)
  • Wear fitted underwear, such as briefs or boxer briefs. Loose underwear, such as boxers, allows too much scrotal movement.
  • Do not take Aspirin or any products that contain Aspirin in the week before or the week after the operation.
  • Please read, understand, sign and bring the Surgical Consent form. We will request it at the doctor’s office and clinic admissions.
  • Do not come by motorbike, bike or scooter. You can drive your car or come by public transport.
  • If you are very worried, take the prescribed medication when you reach the clinic office.

Instructions after the vasectomy

  • Spend a quiet afternoon at home, lying in bed or on the sofa. Minimise any physical activity. Fitted underwear is more comfortable than loose styles. Some men feel no pain after the vasectomy. Many feel mild discomfort that does not require painkillers. Sometimes, discomfort may be noted in the groin or abdomen. This is because testicles originate in the abdomen in embryonic life and move down to the scrotum during pregnancy. Therefore, any issues within the scrotum may be perceived as abdominal discomfort.
  • Avoid taking Aspirin for the first 3 days after the vasectomy. You may take Paracetamol (Gelocatil or generic), two 500-mg tablets every 4 hours if you feel any discomfort. Ibuprofen and/or Dexketoprofen (Nurofen, Enantyum or generic) is a painkiller and anti-inflammatory drug. For the first few days after the vasectomy, inflammation is a normal symptom of the healing process and some doctors prefer not to intervene, therefore acetaminophen (paracetamol) is preferred. If pain persists beyond 3 days, especially if accompanied by certain inflammation of the vasectomy point, above the testicles, this can mean excessive inflammation; then ibuprofen (400 mg every 8 hours) is a good option. Some men feel greater discomfort or sensitivity 3-5 days after the vasectomy than during the first 3 days. This is due to the fact that the body follows a series of steps to respond to the new situation and subsequent steps are sometimes more symptomatic than previous steps. This is not generally a reason for concern.
  • You can shower daily from the morning after the procedure. Use fitted underwear until discomfort disappears.
  • On the day after the operation, you may walk or drive (no motorbikes) as much as you want, but you cannot do any exercise, garden, swim or lift heavy objects. If you have a sedentary job (office job or supervisor), you can return to work immediately.
  • Two days after the procedure, you may return to more physical work (walking, going up stairs…) and carry out your regular activities using fitted underwear. When the pain has disappeared and sensitivity is minimal, you may return to the gym or running, but on the first day, do half what you would normally do: half the weight, half the repetitions, half the speed, half the distance, etc. If you do not experience any pain, you can do your usual training routine the next day.
  • You can ejaculate when you no longer experience any pain or heightened sensitivity in the testicles. You can have sexual intercourse 3 days after the vasectomy. Blood in the semen in the first month or two after the vasectomy occurs in some men, but is of no significance. (REMEMBER THAT YOU CAN STILL IMPREGNATE!)
  • Some men (around one in 20) develop delayed swelling and discomfort on one side, or occasionally on both sides, starting anytime from the first 3 days until 3 months after the vasectomy. This generally represents an exaggerated form of the inflammatory response required to reabsorb and recycle semen. It is efficiently resolved with a 5-7-day cycle of 400 mg of ibuprofen 3 times per day.

The no scalpel vasectomy (NSV) technique was created in 1974 by Dr Li Shunqiang in the province of Sichuan, China.

It is a safe and minimally-invasive technique with a much lower percentage of complications in comparison to a conventional vasectomy. It was first introduced into the Western medical community in 1985 by Dr Marc Goldstein from the Weill Cornell Medical Center – New York Hospital.

Dr Goldstein was the first American urologist trained in the no scalpel vasectomy technique, or ligation of vas deferens by clamping method under direct vision, as it was known in China. Since then, more than 20 million men have undergone no scalpel vasectomies in China.

Results have shown 10 times less bruising, infections and other complications, a percentage of 0.4% for the no scalpel vasectomy compared to 3.1% for the conventional vasectomy.

80% of American doctors that practice no scalpel vasectomies report that patients experience much less pain and bleeding during surgery.

Likewise, with practice, the no scalpel vasectomy can be performed 50% quicker than the traditional vasectomy.

Patients appreciate that there are no stitches after surgery, that the wound heals spontaneously in 72 hours and that post-op pain and inflammation are minimal.

High levels of patient satisfaction result in good publicity through word of mouth, which can help increase the popularity of the vasectomy as a method of permanent contraception. This has been the case in China, where the percentage of female-male sterilisations has inverted from 3:1 (woman-man) to 1:5.

The first no scalpel vasectomy training course in Europe was held in Barcelona in April 1994. (Dr Philip S Li and Dr JM Viladoms).

The no needle anaesthetic procedure for the no scalpel vasectomy using the “MadaJet” needle-free injector was presented in Europe in April 2005 by Dr Doug Stein and Dr Josep Viladoms.
