Fertility, fecundity and fecundability

In demography, fertility indicates the product or output of reproduction, rather than the ability to have children.

Demographers define a third, further aspect of reproduction—fecundability—which is the probability of becoming pregnant, or the likelihood of exposure to the possibility, that depends on the pattern of sexual and pregnancy preventive behaviours.
