I know, it's so nice to have found this thread. I'm WTT at the moment, and think I'm the only one on there, that I've 'spoken to' at least who is going it alone.
I decided to look in to other countries as I didn't like the fact that sperm donors are not anonymous here. I had a bit of a panic about what happens. I mean, does the child just get a letter on their 18th birthday from the clinic saying 'congratulations, your father is...?'
In Denmark, clinics also sell sperm direct to women, which means that it is less clinical. However, I have now started looking in to clinics, but they also look less clinical than the UK. I also like the fact that, with sperm from Denmark, my future child is less likely to meet a half sibling.
I think it also works out cheaper even with paying for flights to Denmark, from what I can remember - it has been a couple of years since I started looking into it, and I looked in to the UK option quite early on.
I'm not sure that I would be brave enough to do it via a sperm donor site. I know a couple of women who have, and it's been absolutely fine for them. But I just like the idea that the sperm has been checked in a clinic.
