Fecundity is known as the capacity that a living being has to reproduce and in turn allow the species to remain on the planet. This occurs in the cases of those individuals who have the required elements in terms of fertility. In other words, it could be said that fertility is the consequence of effective fertility. For many, fertility can be translated as the number of descendants that an individual can generate.

This concept can be used in the field of biology and in this it is applied to describe the capacity that a living being possesses and it can be calculated through the measurement of seeds, gametes, etc. In addition to this, it is important to point out that fertility is limited by several factors such as the environment and all its variations, as well as genetic factors. In this science it is very common that the term fertility is used as a synonym for fertilization. On the other hand, in ecology, fertility is highly relevant, since the maintenance of a given population depends on it. As mentioned above, there are factors that can cause it to vary.

In the field of demography, fertility can be measured through the number of children that a specific generation has, in general this number is associated with women throughout their reproductive stage and this is known as the fertility rate. fertility, it is also possible that it was measured by a general rate, which is known as the general fertility rate. It is important that fertility is not taken as a synonym for birth rate, since the latter only indicates the total number of people born during a year.

In order to calculate fertility, it can be done as follows: first, the specific fertility values ​​of women between the ages of 15 and 49 must be added for a period of 5 years.
