Name the part performing the following functions in the human male reproductive system:

(b) Production of male gametes
(c) Whose secretion makes the transport of sperm easier
(d) Provides suitable temperature for sperm formation
(a) Carries sperm: The vas deferens is the part that carries sperm from the testes to the urethra.
(b) Production of male gametes: The testes are responsible for producing male gametes (sperm).
(c) Whose secretion makes the transport of sperm easier: The seminal vesicles secrete a fluid that aids in the transport of sperm and provides nutrients.
