Biologically, it might be very difficult to get pregnant at that age. And, if a woman does get pregnant, she will need to have an amnio among other tests to check for age-related birth defects.
I agree with this.
Psychologically, if the woman feels she would like to be a mother, I say go for it. Personally, the baby ship has sailed for me (I will be 44 in a month and have an 11 year old only child). But, I would never tell someone else they shouldn't try for a baby if they wanted to at that age.
