I am fit, healthy and slim male in my early fifties, professional with PhD, happily married for 30 years, raising 3 adopted children, two of them already young adults. I can offer my help as a donor. Ideally I would like to have some contact with the child or at least some knowledge about the child, have some presence in his/her life as a friend. I am not able to commit to be full-time co-parent as my family is very important for me and takes all my time and energy. Having said that I would be happy to offer some help raising the child, I am very experienced dad. My wife is fully informed and supports me, actually it was her who encouraged me to offer help to prospective parents, as we went through a lot of pain on our journey to parenthood.
