Sperm need temperatures between 2 to 10 degrees Centigrade lower and then the body temperature to develop. This is the reason why the testes are located in a bag of skin called the scrotal sacs<span> (or </span>scrotum<span>) that hangs below the body and where the evaporation of secretions from special glands can further reduce the temperature and adjust to the temperature it needs.

Viruses have the ability to reproduce on their own and
sometimes within hosts. It is an infectious agent that can affect all types of
life forms (e.g. animals, plants, microorganisms). They are found in almost
every ecosystem on Earth and they are the most abundant type of biological
identity. Asvirology is the study of
viruses which is a sub-specialty of microbiology. The spread in many ways and
can be transmitted from one organism to another or sometimes to multiple
organisms at the same time. Its origins in the evolutionary history of life is
still unclear but they are considered to be life forms because of their
capacity to carry genetic material, reproduce, and evolve through natural
selection. </span>
