It has been four years since the electrocautery ligation, and there are no sperm in the semen. Is there still a possibility of pregnancy?

Hello doctor, I underwent a vasectomy three to four years ago, but this year my girlfriend became pregnant and has already given birth.
I consulted the doctor who performed the vasectomy, and he confirmed that the site of the procedure is intact with no openings, and the sperm count in my semen was zero.
However, after a paternity test, the results showed that the child is mine.
Is this possible? How accurate are the paternity test results? If pregnancy can still occur after a vasectomy, should I use condoms in the future?

Hello: From a medical perspective, there may still be errors in the test results.
I recommend that you seek another hospital for a sperm analysis.
If sperm is still present, pregnancy may be possible.
If the count remains at zero, consider seeking another facility for paternity testing.
The initial examination may have inaccuracies, and repeating the test could help clarify your concerns.
Thank you for your inquiry.

After a vasectomy, the likelihood of fathering a child is significantly reduced, but it is not entirely impossible. A vasectomy is a surgical procedure that involves cutting and sealing the vas deferens, the tubes that carry sperm from the testicles to the urethra. This procedure is considered a permanent form of male contraception, but there are a few scenarios where pregnancy can still occur.

1. Sperm Persistence: After a vasectomy, it can take some time for all remaining sperm to be cleared from the reproductive tract. It is generally recommended that men undergo a semen analysis a few months after the procedure to confirm that sperm is no longer present. If your semen analysis showed zero sperm count, this indicates that the vasectomy was successful in preventing sperm from being present in the ejaculate.

2. Recanalization: In rare cases, the vas deferens can spontaneously reconnect, a phenomenon known as recanalization. This can happen even years after the procedure. If this occurs, sperm can once again travel through the vas deferens, leading to the possibility of pregnancy.

3. Sperm Retrieval: In some cases, sperm can be retrieved directly from the testicles or epididymis through surgical procedures, even after a vasectomy. This sperm can then be used for assisted reproductive techniques, such as in vitro fertilization (IVF).

4. Paternity Testing: Regarding the paternity test, these tests are highly accurate, often exceeding 99% accuracy. If the test confirmed that you are the biological father of the child, it suggests that there was a viable sperm source that led to conception. Given your reports of a zero sperm count, this raises questions about the circumstances surrounding the conception.

5. Contraceptive Measures: Given the complexities and potential for unexpected outcomes, it is advisable to use additional contraceptive methods, such as condoms, to prevent unintended pregnancies. This is especially important if there is any uncertainty about the effectiveness of the vasectomy or if there are any indications of sperm presence.

In conclusion, while a vasectomy is a highly effective method of contraception, it is not infallible. If you have concerns about your reproductive health or the circumstances of your recent situation, it is crucial to discuss these with a healthcare provider. They can provide further testing, guidance, and options based on your specific circumstances. Additionally, if you are considering future family planning, discussing these options with your partner and a healthcare professional can help you make informed decisions.
