Should I use my husband's brother?

So my husband has two brothers and one of them are infertile. Unfortunately the infertile one is the brother that is in the better condition, has a full head of hair, and looks exactly like my husband. (Not that I have complaints about my husband, but if he is going to have my children I'd rather they have his brother's hair). <br><br>The fertile brother looks nothing like my husband, is balding, and doesn't have a good body. <br><br>My husband asked if I would be okay with him being the father if they were genetically his, but I would rather hold off and not use a donor. My husband doesn't want his infertile brother to be the donor as it would be disrespectful and if he did use his brother he would be asking for his brother to keep the secret.<br><br>I know it's weird, but it feels like it would be more "his" if his brother was the donor. Do I go with the hot brother or not?
