A more thorough explanation:

Definition: Words of procreation are a legal language used in a will or deed to indicate the transfer of property to one person and their descendants. These words are typically used as "to A and the heirs of his body," where A is the person who inherits the property.

Example: John's will states that his property will be transferred to his son, Tom, and the heirs of his body. This means that Tom will inherit the property, and if he has children, they will also have a right to the property.

Explanation: In this example, the words "and the heirs of his body" indicate that Tom's children will also have a right to the property. This is because the property is being transferred to Tom and his descendants, not just to Tom alone.
