Can you please explicitly clarify the max number of individuals that can purchase each donor? It is unclear about many siblings are typical or listed in the sibling donor registry (especially if you can't join until you have a healthy pregnancy). Is there a max # of buyers that you permit? How many donor siblings could a child have? How many total offspring do your donors typically have?
For the reserve donors, unfortunately there is no guarantee that the donor didn't go to another clinic to donate, correct? Even if you spend the extra $, there is no guarantee that they won't have tens of siblings, correct?
Also, if you are planning IVF and only IUI samples are listed - can you use that?
