omg i cant believe that was said to you how rude and closed minded.

i dont have personal experience but other options to weigh up are if going with the vasectomy reversal how long are you prepared to wait until you fall pregnant (in other words it may still take years to fall pregnant despite a history of falling pregnant quickly - i got pregnant with DS and DD1 straight away, dd2 was 2 years, the twins were a few months)
where as ivf pressuming all goes as planned would be quicker.

IVF if successful the first cycle would be cheaper than the reversal (subject to rebates)
IVF is a one shot deal - in other words a vasectomy reversal leaves the oppourtunity for more children by accident or having to fork out for a vasectomy all over again, IVF doesnt run that risk

Natural conception has more chance of a singleton pregnancy where IVF is more likely to be mulitples (from knowing quite a few who have gone down that path) but here i am saying that pregnant naturally with twins.

Thats just some of the things i would weight up if i was in your position sorry i cant be of anymore help
