Definition of Fecundity

Fecundity is the natural ability of an organism to produce offspring. It is considered the same concept as fertility. Fecundity is determined by the number of eggs or seeds produced. An organism that lacks fecundity is known as sterile. In the terms of population biology, it is used to describe the number of offspring produced after a one-time step.


Hence, it includes birth rates as well as the rate of survival of young ones till that one-time step. It is considered to be a consistent feature of each culture. It can increase or decrease depending upon the conditions and social factors such as lack of food, high temperatures, etc.
