Need help for a friend dealing with failed vasectomy...

Had lunch with a friend who has been ttc. She is 32 and dh 47. Her dh had a vasectomy and just had a versal about 3 months ago and was told that it failed. She did IVF which she did conceive but ended with a m/c at 6 weeks.

I was wondering if there were other options other than going through IVF....are there any other options for her other than dh doing another reversal which he doesn't want to do.

Any suggestions would be appreciated

Thanks

Thanks
