What's the oldest "acceptable" age a man can father his last baby?

What do you think? 39? 52? 65? How old would a man have to be when having his last child for you to think "that's a bit old isn't it?"

I guess same can be asked for a woman actually? What's "acceptable"?

@Mintjulia

My ds's dad was 56. My df was 58 when my little sis was born.

Neither seem to have any issues

I think it depends on the attitude & outlook of the father.

Not really. Attitude and outlook don't affect physical ageing. A 58 year old is still a 58 year old - and will be approaching retirement age by the time his child starts school and will be in his 70s by the time they are teens - regardless of 'outlook'.
