Comprehensive Unassisted Pregnancy Rates (CUPR) across birth cohorts of women born between 1958 and 1999. The X-axis represents women’s ages from 15 to 45 years. The Y-axis represents the cumulative CUPR, ranging from 0.0 to below 2.5. Multiple cohort lines ranging from the 1958 to the 1999 birth cohort are plotted on the figure. Each line indicates the respective cohort’s CUPR, starting from the lowest values at age 15 and peaking before age 45.
