Surrogate mother

We are married for the past 9 years. We have no kids. We tried for all possible treatments including IVF but no success. Medical problem is in my husband and me too. So if my husband does a second marriage still he is unable to conceive naturally, then will surrogate mothers be permissible in our case. We want to do his second marriage and do surrogacy with her, if allowed in Islam. I have read a lot about surrogacy that it is not allowed but in our case when naturally we cannot have children and our relationship is disturbed a lot due to this lack of kids, can we do surrogacy.
