I am 41 years old, I have a good ovarian reserve and no fertility issues. I will be using a sperm donor. My doctor said that fertilization will have to be done with ICSI because sperm lose their motility after they have been thawed.
My understand is that donor sperm is of the highest quality, and motility is tested by the sperm bank in after a freeze/thaw cycle.
Is ICSI justified here?
