Vasectomy and fertility: options for preservation

A vasectomy is a conscious decision to use permanent contraception. But what if your circumstances change and you decide you want to have children? The good news is that there are various ways to preserve or restore fertility despite a vasectomy. In this article, we explain all your options—from proactive planning to modern medical procedures.

What is a vasectomy?

A vasectomy is a surgical procedure in which the vas deferens are cut and sealed. This prevents sperm from entering the semen, thereby preventing natural conception. The procedure is considered one of the safest and most effective methods of male contraception, with a success rate of over 99 percent.

It is important to note that a vasectomy has no effect on hormone production, libido, or sexual performance. The testicles continue to produce testosterone and sperm—however, these are reabsorbed by the body instead of being expelled during ejaculation.

Why do men choose a vasectomy?

Safety and Effectiveness

The vasectomy offers a level of contraceptive reliability that few other methods can match. After the procedure and confirmation via a follow-up semen analysis, you and your partner can rely on permanent protection—without having to think about it every day, without hormonal side effects, and without recurring costs.

Comparison with Other Methods

Compared to other contraceptive methods, the vasectomy performs exceptionally well:

• Birth control pill: Must be taken daily, hormonal side effects possible, failure rate of up to 9 percent with typical use
• Condom: Correct use is crucial, failure rate of up to 18 percent with typical use
• IUD: Insertion can be painful, requires regular check-ups and replacement
• Vasectomy: One-time procedure, no side effects, failure rate below 0.1 percent

Options for Preserving Fertility

Even though vasectomy is intended as a permanent method, there are certainly ways to preserve or restore fertility.

Reversal surgery (vasovasostomy)

Vasovasostomy is a microsurgical procedure in which the severed vas deferens are reconnected. This procedure is technically demanding and is performed under a surgical microscope.

Chances of success:

• The shorter the time since the vasectomy, the better the chances
• Within the first 3 years: patency rate of up to 95 percent
• After 3 to 8 years: about 80 to 90 percent
• After 15 years or more: the success rate drops to about 70 percent
• Important: Patency does not automatically mean pregnancy—pregnancy rates are slightly lower

What you should know:

• The procedure takes about 2 to 3 hours and is performed under general or spinal anesthesia
• Recovery takes about 2 to 3 weeks
• The costs are generally not covered by health insurance
• A follow-up semen analysis after 3 months will show whether the surgery was successful

Cryopreservation (freezing sperm)

A particularly forward-thinking option is the cryopreservation of sperm before the vasectomy. In this process, sperm samples are frozen in liquid nitrogen at minus 196 degrees Celsius and can theoretically be stored indefinitely.

Advantages of cryopreservation:

• Absolute certainty: You retain the option of having your own children, regardless of how much time passes
• No further procedure required: The sperm can be used directly for in vitro fertilization (IVF/ICSI)
• Planning security: You can undergo the vasectomy with peace of mind

Practical information:

• Ideally, multiple samples should be frozen to ensure sufficient material for future attempts
• Storage takes place in specialized fertility clinics or cryobanks
• Annual storage fees apply (usually between 200 and 500 euros per year)
• A semen analysis is performed before freezing to assess quality

If you are planning a vasectomy and would like to keep this option open, it is best to discuss cryopreservation with your urologist early on.

Consultation and Decision-Making

The decision to undergo a vasectomy should be carefully considered. At our practice in Vienna, we take the time for a detailed consultation during which we discuss the following points with you:

• Your current life situation and family planning
• The possibility of a change of heart — statistically, about 5 to 7 percent of men regret their vasectomy, especially those who undergo the procedure before the age of 30
• Options for preserving fertility, such as cryopreservation
• Realistic expectations regarding a potential reversal procedure
• Alternative contraceptive methods, in case you still have concerns

Our goal is for you to make an informed decision that fits your life—today and in the future.

The Vasectomy Process in Detail

Preparation

A detailed consultation takes place before the procedure. We will explain the procedure, the risks, and post-operative care. You will receive clear instructions on how to prepare:

• Stop taking blood-thinning medications as advised
• Shave the genital area on the day of the procedure
• Bring comfortable clothing and tight-fitting underwear
• It is recommended that you have someone accompany you home

The Procedure

The vasectomy itself takes only 20 to 30 minutes and is performed on an outpatient basis at our practice:

1. Local anesthesia of the surgical area
2. Access to the vas deferens via one or two small incisions (or using a no-scalpel technique)
3. Transection and closure of the vas deferens
4. Wound closure — usually with dissolvable sutures

The procedure is generally painless. You will only feel a slight tugging or pressure.

Aftercare

After the procedure, we recommend:

• 1 to 2 days of rest with cooling of the surgical area
• No sports for one week and no heavy lifting
• Refrain from sexual intercourse for about one week
• Follow-up semen analysis after 8 to 12 weeks — contraception is only considered reliable after this period

You can find more details about the entire procedure on our Vasectomy page.

Conclusion

Vasectomy is a safe and effective method of permanent contraception. For those who still wish to keep the option of having children open, cryopreservation and reversal surgery offer two proven options. A comprehensive consultation before the procedure, during which all aspects are openly discussed, is crucial.

Frequently Asked Questions

Can I have children naturally after a vasectomy?

After a successful vasectomy, natural conception is no longer possible. In many cases, the patency of the vas deferens can be restored through a reversal procedure (vasovasostomy). The sooner the reversal is performed after the vasectomy, the better the chances of success.

When should I have my sperm frozen?

Ideally, before the vasectomy. Cryopreservation is a straightforward procedure that offers you maximum flexibility for the future. Please discuss this option with us during your consultation appointment.

Does a vasectomy affect my hormone levels?

No. A vasectomy has no effect on your hormone production. Your testicles continue to produce testosterone in the same amount as before. Your libido and erectile function also remain unchanged. The only change: there is no longer any sperm in your semen.
