The risks to men of getting married and having children with a woman in western countries are so extreme that frankly I think surrogacy is the only rational option for many men.

From the child's point of view I think this is better than what 25 - 50% get. 50% end up with divorced parents and most of those have little or no contact with their fathers. So these children loose contact with a father that they once loved. With surrogacy they will always have their loving father and they never knew their mother.
