The sex cells ( sperm) are produced in the tubules

seminiferous tubules

Explanation:

there is your answer

Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.

If you are asking if this is a true or false statement, this is false. A nonsteroid hormone does not enters a target cell by passing across its cell membrane, instead it is the steroid hormone that enters the target cell by passing across its cell membrane.
