production of male hormone testosterone; and production of sperm
One of the functions of the testes is to produce sperm. The other function of the testes is to produce hormones, namely testosterone.
When the testes start to produce sperm, they undergo two primary functions: spermatogenesis and hormone production. Spermatogenesis is the process of creating sperm cells from germ cells within the seminiferous tubules. Simultaneously, the testes produce testosterone, which plays a crucial role in the development of male secondary sexual characteristics and regulates sperm production.
The gonads are the testes and ovaries. Both also have endocrine (gland) functions.

Males have two testes because it allows for the production of sperm. Having two testes provides redundancy in case one is damaged or compromised. Additionally, the two testes are able to produce a large amount of sperm, increasing the chances of successful fertilization.

The two functions of DNA are to store genetic information and transmit/express genetic information
There are more than two if you were to disect the testes. Two than come to mind are sperm cells and blood cells but there are also other tissue cells such as skin cells. Perhaps you need to rephrase the question.
You have a primary and secondary tank. Certain air functions of the truck use the primary and others use the secondary tank.
