It’s a bizarre cultural problem.
We did not plan it this late, but just wanted to say that higher age is not a guarantee of bad things.
For men 35 is nothing, men can sire children to their last breath.
Ask your friends who have started families past 35, so many stories about fertility, doctors, etc.
It is also why you see so many twins among middle aged professional couples, the children were the result of fertility treatments.
With the way society is changing, I think eventually human evolution will catch up and allow women to stay fertile later in life.
