The problem has likely to do with the quality of my egg cells. They are not certain about this, but it is the most likely explanation. This means that surrogacy would not solve that problem. An egg cell donation might. However, in my country it is quite difficult to have access to that. There are large sperms banks, but not large banks for egg cells. So, we would need to find someone in our environment to donate an egg cell to me.

Are you a male or female couple (biologically I mean for making the child)? What happens here is that there are some women who do not have a partner, but still want a child. They often get a child together with a male gay couple and they raise the child with the three of them. I think government is even working on it to be possible for a child to have three parents legally. This is how my uncles got their twins. I am not sure whether this works the same with female couples. I see them often at the fertility treatment center, so I believe that they probably use the sperm bank.
