The primary function of the testes in males is to produce sperm and male hormones, such as testosterone. This is a critical component of male reproductive biology. The testes are responsible for spermatogenesis, the process of producing sperm, which is vital for reproduction. Additionally, the testes are the main site for the synthesis of testosterone, which plays crucial roles in the development of male secondary sexual characteristics, maintenance of libido, and overall male reproductive health.

The other options pertain to functions that are not performed by the testes. For instance, the production of estrogen and female hormones is primarily associated with the ovaries in females, while the storage and development of ova (eggs) are also functions specific to female reproductive anatomy. The option about secreting hormones to inhibit sperm production does not accurately reflect the role of the testes, as they primarily produce hormones that stimulate sperm production and male characteristics.
