Wow, yeah, I can't believe he is suggesting that you do at home IUI with unwashed sperm. This is an RE?!
I will also say that, for me *personally*, sperm bank "doesn't freeze well" and KD "doesn't freeze well" could be different. When we were shopping for frozen sperm, high numbers was the top priority. Now that we have decided to go with a known donor - because that option for family building, with this particular person, was a better (ideal!) choice for us than frozen ID release - well, the relationship part trumps the numbers for me. Within reason, I guess! And I totally agree that the numbers can change over time, even short periods of time.
