Some posts lack tact - yes I agree.
The point isn't that it's disgusting though. It's that there's significantly increased risk.
And what about the potential child? My dad has been a great dad, genuinely, but he was never as energetic as my friends dads when I was young. He couldn't do as much with me. I am neurodivergent, which has been linked to advanced paternal age.
I have had to face the idea that I will likely lose him before I am 40. I am nowhere close to marriage, so he may never get to walk me down the aisle.
He may never meet any children I have (if I'm lucky enough to have them). The idea crushes me. He may require a lot of care from me whilst I'm still relatively young.
I wouldn't swap him for anyone, but in the same breath I would never put a child in the same position. Of course younger fathers than be absent, financially inept and useless but so can older ones. Of course anyone can die while their kids are young, but its far more likely when the parents are older. Of course anyone can inherit a genetic abnormality, but it's far more likely when parents are older.
It's about minimizing risk and IMO the OP should pursue other avenues if she can, to give her potential child the best possible chance. A child born through sperm donation, who only has a (brilliant, strong, courageous to go through it on her own -OP) mother, is not likely to miss a father they never had
