Ending aging will not reverse this trend. Many people only have kids due to age constraints and its effect on fertility and the health of offspring, ie. much harder to get pregnant over 35, and chance of birth defects or other problematic genetic problems increases dramatically, even for men.
This will no longer be the case, so there would be no rush for either gender to have kids. You can focus on your career for the first hundred years, and then have kids. At worst, there would be a minor uptick in population while people get accustomed to the new reality.
