A man and a woman are both required to produce a child.
However, this NHS website is aimed at those who are expecting a child, not those who necessarily fired their sperm at the egg, or had their egg ready and waiting for the...'shot'.
Biologically, you are absolutely correct...a man and a woman produce a child. However, as we all know, it doesn't necessarily mean that a man and a woman will bring that child up.
There are hundreds of thousands of children who grew up without fathers after the war, for example - and in future there will be more and more same-sex couples who will either adopt, or via egg donors, become parents. It makes sense for government resources to reflect this, in the same way that government resources had to be altered to reflect civil partnerships.
The alternative is to assume that all relationships are built exactly the same and ignore what doesn't fall within predetermined societal rules.
I'm not sure I can see the point of that.
