Secure & discreet access
Your privacy before, during and after care
Open a heading only when you want the detail.
Explore without identifying yourself
Reading patient information and using the private reflection does not ask for your name or create a clinical record.
Identified only when care needs it
Your identity and health information are collected only when you submit a clearly labelled booking, registration, informed-choice or recovery form.
Restricted clinical access
Submitted clinical information is available only through authorised staff workflows within the clinic or organisation responsible for your care.
Discreet screen and messages
Sensitive pages cover themselves after you switch apps. Push notifications are off, and opted-in SMS reminders use neutral preview wording.
Using a shared phone safely
Use a screen lock, turn off lock-screen message previews and avoid installing the app if the WISPIVAS name or icon would reveal more than you want. No website can erase browser history or prevent another person from taking a screenshot.

Benefits of vasectomy
Vasectomy can be a useful choice for a man who is sure he does not want future biological children, whether his family is complete or he chooses not to have children. The decision must be informed and voluntary.

Choose the family size that is right for you
Vasectomy helps prevent future pregnancies when you are certain you do not want more biological children, or any biological children. It can support the family life you choose. You do not need to decide today, and you can change your mind before the procedure.
Use a lasting, hormone-free method
Vasectomy is highly effective permanent contraception. After clearance, it avoids daily pills or repeated contraceptive injections for pregnancy prevention within that relationship. It does not lower testosterone or normally affect erections, orgasm or sexual desire. Condoms may still be needed for infection protection.
Reduce risks from unintended pregnancy
Preventing an unintended pregnancy avoids the health risks of that pregnancy and birth. Family planning can reduce pregnancy-related illness and deaths and the need for unsafe abortion. This is an indirect benefit of preventing pregnancy; vasectomy does not treat an existing pregnancy, obstetric fistula or any other complication.
Plan time, care and household resources
Choosing whether to have further children can help you plan for housing, food, education, healthcare and the time and emotional support your family needs. Family circumstances differ. Vasectomy does not guarantee financial security, a stronger relationship or responsible parenting.
Exercise your reproductive health choices
Access to family planning supports informed decisions about whether to have children. In Kenya, Article 43(1)(a) of the Constitution recognises the right to health, including reproductive healthcare. Choosing vasectomy should be free of pressure, including pressure linked to sponsorship, poverty or family size.
Support the children already in your care
If you have children, planning your family can help you focus your care and resources on them. Kenya’s Constitution, Article 53(1)(e), recognises a child’s right to parental care and the responsibilities of both parents. Vasectomy does not remove existing responsibilities or guarantee that a parent will meet them.
Continue caring for your overall health
WISPIVAS encourages healthy eating, regular activity, avoiding tobacco and limiting alcohol. These support general wellbeing; they are not effects of vasectomy. During recovery, follow your clinician’s guidance before returning to exercise or strenuous work.
Before you decide
Treat vasectomy as permanent: reversal may fail. It does not work immediately. Continue contraception until your clinician reviews your semen test and confirms clearance. It does not protect against HIV or other sexually transmitted infections. Bleeding, infection, persistent scrotal pain and rare failure can occur. Discuss benefits, risks and reversible alternatives with your clinician before the procedure.
Your care journey
1What is a vasectomy?
Vasectomy is a minor operation for permanent male contraception. It prevents sperm from entering the semen that is ejaculated during sex, so sperm cannot reach and fertilise an egg.
Sperm are made in the testicles and normally travel through two small tubes called the vas deferens. During a vasectomy, the clinician blocks or divides these tubes. The testicles continue to make sperm, which the body absorbs.
In no-scalpel vasectomy (NSV), the clinician reaches the tubes through a small puncture in the skin of the scrotum rather than a conventional skin incision. Local anaesthetic numbs the area. You remain awake; tell the clinician if you feel pain so they can address it.
Vasectomy does not remove the testicles. It does not reduce testosterone and should not affect sex drive, erections or orgasm. You still ejaculate semen, most of which comes from glands rather than the testicles.
It is intended to be permanent. Reversal is not always successful, so discuss other contraceptive options if you may want children in future.
Vasectomy does not protect against sexually transmitted infections, including HIV; use condoms for protection.
Rare but possible risks
Possible risks include bleeding, bruising, infection, persistent scrotal pain and the small possibility of failure or later reconnection. You can discuss these risks and seek any further clarification from your clinician before the procedure. A further procedure may occasionally be needed.
2Eligibility and your decision
Wispivas accepts registration from adults aged 21 or older. You must be able to understand the information and make a voluntary, informed decision. Registration is an initial screen; a clinician makes the final assessment.
Discuss your plans for future children and any uncertainty during counselling. Partner discussion is encouraged where appropriate, but spousal permission is not mandatory. HIV status alone is not a reason for exclusion.
Tell the team about allergies, medicines, bleeding problems, prior groin or scrotal operations, current infection and persistent scrotal pain. These may require assessment, treatment or a change to the timing or approach. You can ask questions, postpone or withdraw your decision before the procedure.
3Fee, payment and practical arrangements
Fees and payment methods vary by country and clinic. Your selected clinic will confirm the applicable fee, accepted payment methods and correct payment destination before your appointment. Do not send money to a clinic or account unless the details have been confirmed for your location.
If you need sponsorship or plan to use insurance, discuss arrangements with the clinic before your appointment. Funding is not automatically approved. Any sponsorship involving sharing personal information requires a separate explanation and agreement. Reading this package does not authorise disclosure to a sponsor.
You can cancel an appointment through the cancellation link or staff at least 3 hours before its scheduled time. For later changes, contact the clinic directly. For questions about preparation or follow-up, contact the clinic providing your care.
4Before your appointment
Confirm your clinic, date and time. Arrange transport home and allow time to rest afterwards. Bring identification and a list of medicines and allergies. Keep your payment confirmation for verification.
Follow the clinic’s instructions on washing and hair removal. Eat normally unless your clinician gives different instructions. Wear comfortable clothing and bring supportive underwear.
Tell the clinician if you take aspirin, blood thinners or supplements. Do not stop prescribed medicines yourself; ask for an individual plan before the appointment. Report fever, infection or new scrotal symptoms before travelling.
5Aftercare and recovery
Rest after the procedure and follow the written discharge instructions from your clinician. Supportive underwear can help reduce discomfort. Take pain relief only as advised and follow the label.
Avoid strenuous exercise, cycling and heavy lifting until the clinician says it is appropriate, commonly for one to two weeks. Resume sexual activity when comfortable and in line with your discharge advice. Do not drive home after the procedure; resume driving only when you can safely control the vehicle and perform an emergency stop.
Keep the wound clean and follow the clinic’s instructions for bathing and dressings. Mild bruising, swelling or discomfort may occur. Contact the clinic if symptoms worsen or do not settle.
Seek prompt medical review for increasing pain or swelling, fever, pus or discharge, or ongoing bleeding. For severe or rapidly worsening symptoms, go to the nearest urgent-care or emergency facility. Do not wait for a reply through this registry.
6Semen testing and contraception
Vasectomy does not work immediately. Continue using reliable contraception until your clinician has reviewed your post-vasectomy semen analysis and explicitly confirmed clearance. Reaching three months or a particular number of ejaculations alone is not clearance.
Arrange the semen test as instructed by Wispivas, usually around three months after the procedure. Follow the laboratory’s collection and delivery instructions. Repeat testing may be needed. Contact the clinic if you have not received your result; do not assume that no message means the test is clear.
