Hi Penny. You are right, not all can be reversed but, this can be spotted on the consultation for a cost of £180.
The Surgeon I know of had a 92% success rate last year alone and on average he does on average 300 reverse vascestomies a year.
The closer the dates between the vascestomy and the reverse vasectomy, the higher the chance.
Bearing in mind the people having all done in there 20's have a bigger chance anyway.
Looking at the other end where the guy had his vasectomy 15 years ago the stats are not as good as the guy in his 20's but, what must be remembered is, the guy who had his vasectomy 15 years ago is 9 times out of 10 more than likely be married or partnered with a women much older than the 'prime' baby making years IE 18 to 35 years old. This must also be considered when looking at stats.
So if the guy had his vasectomy 15 years ago and his wife/partner is with in her 'prime' years there is every chance of it being successful, just like the guy in his 20's.
The facts are the highest chance is in your 20's (3years and below vasectomy) which is 97% the lowest being 79% ( thoses are guy with 15 years plus between vasectomy and reversal) chance of getting pregnant.
For the small cost of the reversal when you compare the cost with IVF, it is well worth it.
Bear in mind the average IVF treatment in the UK costs £2500 each time. The cost of the reverse vascetomy at this hospital I know of in the Midlands costs the same as the IVF and you get that chance of getting pregnant every month there after, unlike IVF where you have to spend £2500 each time.
Yes, you may have to go down the IVF route if the reverse operation don't work, better to do this first though.
So, yes Not all can be reversed but, look at the chances of sucess, from 97% to the low of 79%, well worth a bet it works Penny.
When you think many play the lotto every week and that is a 14 million to 1 chance of winning.
You have to be in it to win it.
