My partner and I are interested in TTC in the new year. We are in a delima now about wether we should use a close friend and a known doner or a sperm bank. The known doner has expressed interest in becoming parents with my partner for several years and they are very close. I am not sure if this will be in our best ineterest or the baby's for that matter. On one hand we would like our baby to be able to know his/her father, however this seems to imply complications legaly in the future. He has expressed that he would like the baby to cary his last name and to have monthly or anual visitation.
