Fertility  (FERTILITY)


The capacity of a man, a woman or a couple to participate in reproduction (i.e., the production of a live child) is called fecundity1. The lack of that capacity is called infecundity2, sterility2 or physiological infertility2. Fertility3 (601-1) on the other hand means actual reproductive performance —whether applied to an individual or group. It should be noted that in many Latin languages, the etymological equivalents of fertility and fecundity are used in a sense diametrically opposite to that in English. Thus, the French fécondité or the Spanish fecondidad are properly translated by fertility, and fertilité or fertilidad by fecundity. It should also be noted that although the conventions outlined above are generally followed by demographers, the terms fertility and fecundity are used much more loosely in medical literature, where they are sometimes treated as being almost synonymous. Childlessness4 may be due to sterility, but like the word infertility4 includes both physiological infertility (621-2) and voluntary infertility5 which is often inaccurately called voluntary sterility5.

  • 1. fecundity n. — fecund adj. The term sub-fecundity when applied to an individual means that the capacity is below normal; it is also sometimes applied to a group of persons rather than to an individual.
  • 2. sterility n. — sterile adj. — sterilize v., to make sterile, sterilization n., the operation of sterilizing. — infecundity n. — infecund adj.
  • 3. fertility n. — adj. fertile. The term sub-fertility has been used to apply both to persons and to groups of low fertility, and also to groups which should properly be called sub-fecund, because their low fertility is due to physiological causes.
  • 4. infertility n. — infertile adj. — childlessness n. — childless adj.
