I am currently going through the process of looking for a donor. I have found a potential donor off a website, where I placed an ad seeking a donor.
I am going down the known donor route, as the IVF clinic I go through will only use the sperm of a known donor. I have 18 eggs on ice from a cancelled cycle, so ideally I wanted them to be used and not wasted.

DH and I first had a counselling session at the IVF clinic to make sure that we were ready to use a donor and the counsellor gave us some great ideas of where to look for a potential donor.

We were very lucky in that we had some people interested in donating to us just 2 days after placing the ad, although we have had some weirdo's offer to donate as well.

I hope everything goes well for you and that you find a donor soon.

PM me if you need anymore details.
