Reproductive system infection

The biological process through which parents produce new children is called reproduction. A reproductive system is a group of internal and external organs that collaborate to allow males and females to reproduce. Many experts believe that the reproductive system is one of the most important systems in the body due to its crucial function in the survival of the species. Among the body's basic systems, the reproductive tract is the one that differs the most between sexes, and it is also the only one that does not operate until puberty.
