Fertility is the natural capability of producing offsprings. As a measure, "fertility rate" is the number of children born per couple, person or population. Fertility differs from fecundity, which is defined as the potential for reproduction (influenced by gamete production, fertilisation and carrying a pregnancy to term). A lack of fecundity would be called sterility.
Human fertility depends on factors of nutrition, sexual behavior, culture, instinct, endocrinology, timing, economics, way of life, and emotions.

Famous quotes containing the word fertility:
“It is the genius of our Constitution that under its shelter of enduring institutions and rooted principles there is ample room for the rich fertility of American political invention.”
—Lyndon Baines Johnson (1908–1973)
“Go bind thou up young dangling apricots
Which, like unruly children, make their sire
Stoop with oppression of their prodigal weight.
Give some supportance to the bending twigs.
Go thou, and like an executioner
Cut off the heads of too-fast-growing sprays
That look too lofty in our commonwealth.
All must be even in our government.
You thus employed, I will go root away
The noisome weeds which without profit suck
The soil’s fertility from wholesome flowers.”
—William Shakespeare (1564–1616)
“I will go root away
The noisome weeds which without profit suck
The soil’s fertility from wholesome flowers.”
