The stories from Anonymous Us are very powerful. Here is an extract from one called Safety in Biology:

When I tell people I wish I had been raised by my real father often they are offended and say things like, “Your real father is the man that raises you, kisses your scrapes, tucks you in, reads you stories and loves you.” This is a wildly naive idea and if donor conception and the adults that use it could reliably provide social fathers that do these types of things then maybe I wouldn’t have so many problems with the practice.

I strongly believe, because of his lack of biological connection, social fathers are generally much-less-likely-to sufficiently-raise-their-children. Let me say it another way: Nature hinders man’s ability to raise a child that is not his biological offspring as well and with as much grace and love, as the child that IS his biologically….

I’ve tried to bring up sexual abuse as it relates to donor conception before and some say it has nothing to do with the practice. Children are EIGHT TIMES as likely to be abused by a step-father or “social” father. For the ones that are good dads I’m really happy for them, and keep up the good work, but artificial insemination for straight women inherently means that they are being raised by a man or men that have no biological link to them. Biology adds safety.

The body matters.
It doesn’t matter how smart you think you are or your husband is. My step dad had more degrees than he knew what to do with. This is something bigger than human intelligence-it’s nature.
