In-depth analysis: Trends, implications, and future projections
Age rose 3.5 years 1972-2015, continuing due to education/economics. The gradual rise, evident in decade-by-decade increases, is linked to longer schooling, career establishment, and later marriages. Implications: Health risks like autism and schizophrenia in offspring due to advanced paternal age, but older fathers often provide greater financial stability and resources, leading to potentially better educational outcomes for children. Projections: 32+ by 2030, with ongoing monitoring for reproductive health effects.
