Are there any moral reasons why the average person should have biological children while millions of children currently existing need adoption?

I am wrangling with this thought on the way to getting a potential vasectomy. Why exactly should I want to have biological children when I know for a fact that there are all of these children that need my help who already exist? 

I am starting to feel like I do not actually have good reasons to ever want biological children and this is surprising to me, yet I still have an open mind to be changed. I think having biological children of my own just to say that I could have children with my own traits is not a good enough moral reason to essentially abandon all of these other children with enormous needs.

What are your thoughts on this?

For an action to be permissible, all that is required is that there aren't any decisive reasons not to do it.    Your question is one of whether there are any reasons to have children, but the question should be whether there are any decisive reasons not to have children.

Compare: is it permissible to move to a more expensive home, given that the money could be spent on humanitarian aid instead?  These are all cases of the demandingness problem in ethics, particularly as it relates to consequentialism.
