Author: Editorial team of Wyspa Medycyna Przyjaznej · Medical consultation: to be confirmed before publication · Publication: to be completed · Updated: 08.07.2026

The article is of educational nature and does not replace a urological consultation. The decision to have a vasectomy should be conscious, well-thought-out and discussed with your doctor, because the procedure should be treated as a method of permanent contraception.

The most important information at a glance

• Vasectomy involves cutting, closing or blocking the vas deferens.
• After the procedure, the testicles continue to produce sperm, but they do not reach the ejaculate.
• Vasectomy does not lower testosterone and should not affect erection, libido or orgasm.
• The treatment does not work immediately - there may still be sperm in the semen for some time.
• Until effectiveness is confirmed in semen analysis, another method of contraception must be used.
• Vasectomy does not protect against sexually transmitted diseases.
• Vasectomy reversal is sometimes possible, but not guaranteed, so the procedure should be considered permanent.

What is a vasectomy?

Vasectomy is a urological procedure performed on men who want to use a permanent method of contraception. It involves interrupting the transport of sperm from the testicles to the semen by closing the vas deferens. After a successful vasectomy, ejaculate continues to appear, but it should not contain sperm capable of fertilization.

The treatment does not remove the testicles, does not affect testosterone production and does not change male hormonal balance. Most semen volume comes from accessory glands, such as the seminal vesicles and prostate, so ejaculation usually looks similar after vasectomy.

How does vasectomy work?

The vas deferens are the tubes that transport sperm from the epididymis towards the urethra. During a vasectomy, the doctor finds the vas deferens and closes it with one of the surgical techniques. Thanks to this, sperm do not reach the ejaculate.

After the procedure, sperm may still be present in the distal part of the seminal tract for some time. For this reason, vasectomy is not effective immediately. Only a semen check-up allows you to confirm that you can discontinue using other contraception, as recommended by your doctor.

Important: you still need to use contraception after vasectomy

This is one of the most important points. After the procedure, the patient does not immediately become infertile. Sperm may remain in the semen, so another method of contraception should be used until the semen is checked and the effectiveness of the procedure is confirmed.

In practice, semen analysis after vasectomy is usually performed after a certain period of time and after an appropriate number of ejaculations - often about 12 weeks after the procedure and after a minimum of 20 ejaculations, depending on the doctor and laboratory recommendations. The patient receives the final recommendations after the procedure.

Who can consider vasectomy?

Men who are sure that they do not want to have children in the future or do not plan to have another child may consider vasectomy. This is a decision of great importance in life, so it requires a calm conversation with your doctor and - in many cases - also with your partner.

Vasectomy may be appropriate for couples who are looking for a permanent method of contraception and are unwilling or unable to use other methods. However, it should not be undertaken under the influence of a temporary crisis, pressure from a partner, financial situation, family conflict or the belief that "it can always be easily reversed."

Advantages of vasectomy

The most frequently mentioned advantages of vasectomy are:

• high contraceptive effectiveness after confirmation by semen analysis result,
• no effect on testosterone and the male hormonal balance,
• no need to use daily contraception after confirmation of effectiveness,
• outpatient procedure, usually performed under local anesthesia,
• short duration of the procedure and relatively quick return to daily activities in most patients.

At the same time, it is worth remembering that no method of contraception gives an absolute guarantee, and vasectomy requires semen control after the procedure.

What is the preparation for vasectomy like?

Before the procedure, a urological consultation takes place. The doctor discusses the health condition, previous surgeries, medications, allergies, chronic diseases, coagulation disorders, skin infections and the patient's motivation. It is also important to discuss the permanent nature of vasectomy and the need for semen analysis after the procedure.

Before the procedure, the patient should tell the doctor about:

• anticoagulant and antiplatelet drugs,
• coagulation disorders or bleeding tendency,
• allergies, especially to anesthetics and dressings,
• active skin infections in the scrotum or groin area,
• previous surgery on the scrotum, testicles, hernia or vas deferens,
• chronic pain in the testicles or scrotum.

You should not discontinue anticoagulants on your own - the decision must be agreed with your doctor.

How is the vasectomy performed?

Vasectomy is usually an outpatient procedure performed under local anesthesia. The technique may vary depending on the operator and the patient's anatomical conditions. Most often, the doctor makes a small incision or puncture of the scrotal skin, finds the vas deferens, interrupts its continuity and secures the ends of the vas deferens with an appropriate technique.

1. Local anesthesia: the treatment area is anesthetized.
2. Access to the vas deferens: the doctor makes a small incision or puncture in the skin of the scrotum.
3. Closure of the vas deferens: the vas deferens is cut, closed or blocked by a chosen technique.
4. Skin supply: the wound is protected with a dressing and, depending on the technique, may or may not require a stitch.
5. Recommendations after the procedure: the patient receives instructions regarding rest, hygiene, sexual activity and semen analysis.

On the website of the Friendly Medicine Island it is indicated that vasectomy is performed by urologists: Dr. Jakub Krukowski and Dr. Jakub Krącz. The current availability of doctors, procedure techniques and recommendations should be confirmed during registration or consultation.

Recovery after vasectomy

After the procedure, you may experience tenderness, slight swelling, bruising or discomfort in the scrotum. In most patients, symptoms gradually improve within a few days. In the first period after the procedure, it is usually recommended to rest, limit physical activity and wear supportive underwear, according to the doctor's instructions.

Intercourse can usually be resumed after the pain subsides and as directed by your doctor. However, it should be remembered that additional contraception is necessary until the effectiveness of the procedure is confirmed in semen analysis.

• During the first days, avoid intense exercise, lifting and sports.
• Use dressing and hygiene as recommended by your doctor.
• Wear supportive underwear if your doctor recommends it.
• Do not bathe in a bathtub, pool or sauna until your doctor consents.
• Report urgently if you experience increasing pain, severe swelling, fever, purulent discharge or bleeding.

Semen analysis after vasectomy - why is it mandatory?

Post-vasectomy semen analysis confirms whether there are no sperm in the ejaculate or whether the result meets the safety criteria specified by the doctor and the laboratory. Without this test, the procedure cannot be considered contraceptive effective.

If sperm are still present in the test, your doctor may advise you to continue using contraception and repeat the test. Rarely, further management may be necessary if the result indicates failure of vasal closure or recanalization.

Possible risks and complications

Vasectomy is a minimally invasive procedure, but like any surgical procedure, it is associated with possible side effects and complications. Most often, they are mild and temporary, but the patient should be aware of them before giving consent.

• scrotal pain, tenderness or discomfort,
• swelling and bruising,
• bleeding or hematoma,
• wound infection,
• seminal granuloma,
• transient pain during ejaculation,
• chronic pain scrotum or testicles, rare but possible,
• failure of the procedure or late recanalization of the vas deferens,
• need for repeat semen analysis or further treatment.

Risks and recommendations should be discussed with your urologist during your consultation.

Vasectomy and sexuality, testosterone and ejaculation

Vasectomy does not involve removing the testicles and does not block testosterone production. It should not affect the ability to have an erection, libido or the feeling of orgasm. The man still ejaculates because most of the semen volume comes from the accessory glands rather than the sperm itself.

However, vasectomy does not protect against sexually transmitted diseases. Condoms should still be used when having sex with new partners.

Can a vasectomy be reversed?

There are reconstructive surgeries aimed at restoring the continuity of the vas deferens, but they should not be considered a guarantee of return of fertility. Effectiveness depends, among others, on: on the time since vasectomy, technique, operator experience, partner's fertility, presence of antisperm antibodies and many other factors.

Therefore, vasectomy should be treated as a permanent method. If you are unsure whether you may want to have children in the future, you should discuss alternatives with your doctor, including other methods of contraception or possible sperm protection before the procedure.

Myths around vasectomy

Myth 1: Vasectomy lowers testosterone

Fact: vasectomy does not block testosterone production because the testicles still function hormonally.

Myth 2: There is no ejaculation after vasectomy

Fact: ejaculation still occurs. The difference is that after a successful vasectomy, there should be no sperm in the ejaculate.

Myth 3: Vasectomy works immediately

Fact: sperm may still be present in semen for some time after the procedure. A follow-up semen analysis and further contraception are needed until effectiveness is confirmed.

Myth 4: Vasectomy can always be easily reversed

Fact: reconstruction is possible, but its effectiveness is not guaranteed. Vasectomy should be treated as a permanent method.

Myth 5: Vasectomy protects against sexually transmitted diseases

Fact: vasectomy protects against pregnancy once proven effective, but does not protect against sexually transmitted infections.

What to ask a urologist before vasectomy?

Before making a decision, it is worth asking your doctor a few questions:

• Is vasectomy a good choice in my situation?
• What technique will be used for the procedure?
• What are the possible complications and how often do they occur?
• How long should I limit my physical activity?
• When can I resume sexual intercourse?
• When and where to perform semen analysis after the procedure?
• How is the semen test result interpreted?
• What to do if there are still sperm in the test?
• Should I consider sperm banking before surgery?
