If he has gone back to have it tested, I'd say none. If he hasn't then there is no gautantee that it worked properly.
Untied the vasectomy first before you can get pregnant.
Your chances of getting pregnant are up to 100%. Wrap that rascal!
The possibility of somebody getting pregnant when their partner had a vasectomy 27 years ago is unknown. From a forum basis it appears to be common, especially years after the vasectomy took place. From a scientific basis, there is documentation of the male body correcting a vasectomy over time and the same has been noted in women who've had their tubes tied. It was generally considered rare, but the likelihood of this occurring increases with the amount of time after the vasectomy took place. For some men, the chances of this are very high and for others unheard of. It is possible.
immediately in the next few months after, yes. but, if the vasectomy worked, in about half a year he will be infertile
It is very possible to become pregnant after your partner has had a vasectomy. It can take up to 12 months for all of the sperm to be out of the testicles and seminal fluid. Have your partner go for testing on his ejaculate to check for the presence of sperm.
Normally no, but rarely, it could happen, especially right after the surgeries.
No changes at all- except you no longer have to worry about your partner becoming pregnant.
Possibly. You do often hear stories of people who have become pregnant even after their husband/partner has had a vasectomy
It's possible, but very unlikely to get pregnant if a woman has had a bilateral tubal ligation and her male partner has received a vasectomy.
Nearly 0%, due to the vasectomy more than the fact that you are breastfeeding, etc; but nothing is fool proof except abstinence.
The chances are reduced but it only takes one, so there is a chance. If you can afford it, in vitro fertilisation (IVF) might be appropriate. Discuss it with your partner and your doctor. Good luck
There is always a slim chance - but by the sounds of it you should be fine.
