In many respects, the offspring of sperm donors are not doing well. Here's how the researchers summarized the findings of their study, "My Daddy's Name Is Donor:" ... Approximately two-thirds affirm the right of donor offspring to know the truth about their origins. And about half of donor offspring have concerns about or serious objections to donor conception itself, even when parents tell their children the truth. However, despite those reservations, the researchers found that 20% of those surveyed had already participated in some sort of assisted reproduction as adults, either as sperm/egg donors or as surrogate mothers. That compared with only 1% of the adults raised by their biological parents and 0% of those who were adopted.
