Positive pregnancy test after VASECTOMY. How is this possible?

Resolved Question:


I am 43 years old patientold and I have tested positive for pregnancy with a home test kit. My husband is 47 and had a vasectomy 10 years old patientago. How can this be possible? Can this be the beginning of menopause and be a "False Positive"? My last period was around July 4th. My breasts are swollen and tender. No other symptoms. I have read that vasectomy failures are rare and that getting pregnant at 43 is difficult. Being pregnant seems very unlikely given my age and my husbands vasectomy. 

What should I do next? Also I do not have health care coverage. 

My mother had 7 children with her last child born when she was 40. She is very healthy and has never had any medical issues. I am also very healthy and have no medical issues. Non smoker, non drinker.

Thanks for your query at
Sometimes, but rarely, a vasectomy fails.
Yes, after years old patienttoo.
It is possible but rare.
It is not likely to be a perimenopausal false positive.
Well, next - please have an ultrasound scan and get the pregnancy confirmed.
If you wish for a termination, I can then guide you accordingly.
All the best.
Please feel free to discuss further.

Patient replied :

Thank you for your response. I would not want to terminate. Would this pregnancy be considered higher risk due to my age (43)? What are the odds of a miscarraige? Chemical pregnancy?

A chemical pregnancy generally would not show up on the urine test ( home kit ).
You can confirm only when a scan is done.
An odds of a miscarriage are considerably higher at this age, compared to a woman with a younger pregnancy.
The risk of anomalies such as Downs Syndrome too increases.
Pregnancy-related complications such as hypertension, diabetes during pregnancy, malpresentation, difficult labour, increased chance of C-section, placental complications - all have higher incidence after 40.
If you wish to continue this pregnancy, do so after having understood and accepted these risks, with a ' calculated risk ' and proceed ahead after consultation with a Fetal medicine expert.
Take care.
