In the case of most gamete donors, there is no intent to parent. I tend to think the of the term "mother" along with some intent- an intent to parent or in the case of adoption with a birth mother, the intent to not parent (which is an amazing and selfless decision some women do make)
A gamete donor provides an invaluable gift--I tend to prefer genetic donor.
But that has gotten way off the topic at hand, and yes, you can arrange various forms of contact with donors through an ART attorney. Generally, this is not done through clinics-
