I would like to see if Cheryl has any data (hard evidence) to support her assumption. I provided published data while she has made an assertion based on anecdotal evidence and a media beat-up of a story.
Here is Cheryl Miller's response to my rebuttal:
I agree with Damian Adams that the reasons for gamete donor shortages in Europe and Australia are complex. While bans on anonymity have played a role, so have laws limiting or prohibiting compensation to gamete donors (which many donor-conceived activists support) and donors’ growing fears that clinics cannot guarantee their anonymity. (Many donors were spooked when New Scientist reported in 2005 that a 15-year-old boy had found his anonymous sperm donor through a genealogy website.) Nonetheless, countries that permit donor anonymity—such as the U.S. and Spain—have not experienced shortages and are major destinations for fertility patients seeking a donor.
These would-be parents’ desire for children is hardly a “whim.” Donor offspring are right to fight for greater openness, but openness should not be their only goal. Indeed, as I noted in my article, the right to information does not necessarily lead to greater openness. A mandated registry might win offspring the right to know their donor’s identity, but if it means future parents are less willing to disclose their children’s status, it won’t be much of a victory.
