Since developed countries are experiencing population aging, I would guess if someone could help women prolong their window of having healthy births. I say this because if you look at the last ten years, the rate of births in the age ranges of < 18, 18-35 have been decreasing while the age of women getting pregnant in the 35+ range has been increasing. The birth rate of the United States is only as high as is now largely because of the immigrant population. As more women in developed countries choose to have careers and go through higher education, the median age of pregnancies will continue to rise.
