What does it mean to be "Donated"?

And more specifically how does this term affect how we view ourselves and the
practice of donating gametes?

I have heard numerous donors (both egg and sperm) equate it to donating blood. I find this quite disturbing in that a human life, a person who carries this person's blood and genes into the next generation can just be "donated" away. Providing eggs and sperm is so dissimilar to donating blood that these donors must have a need to convince themselves of this arguement so that they can reconcile the concept that a child who is no different from any of their other children from a biological origin perspective can be given away without another thought. It is also quite demeaning that we as human beings are subject to the conceptualisation of being equated to consumable body parts such as blood.

I also feel like these donations are being viewed as a charitable cause. We are not a charitable donation that can just be given away to some "needy" person/couple, like the taxable monetary gift that many people make that also makes them feel good about themselves as caring human beings. There are strings attached and when these strings get severed (the biological connections), we don't function psychologically as well anymore.

A donation is a gift, it is a giving away. We have been given away by one or more of our biological parents. To be not wanted by ones' flesh and blood, our kin, and given away is painfull. I'm scarred.
