Fig. 3: Age-specific fecundability estimates in FPsim-Senegal.

This panel shows the fecundability parameter estimates by age. These estimates indicate the probability of conceiving in a 12-month period. Each individual also receives an individual variation multiplier, which can bring fecundability up or down across her life course, to represent the real-life individual heterogeneity in underlying capacity to conceive. The shaded area represents the full range of possible fecundability curves.
