Glands

Secrete seminal fluid

Supporting structures

Penis and Scrotum

Semen

Mixture of seminal fluid from the glands plus the sperm

Semiferous tubules are made of

Spermatogenic cells, Sertoli cells, and Ladydig cells

Spermatogenic cells

Are sperm forming cells

Sertoli cells

Provide nourishment to spermatogenic cells

Laydig cells

in the testes, located in between the semiferous tubules

Produces testrone male sex hormone

Epididymis

Stores much of sperm produced by testes, where sperm matures

Vas defrens

Transports sperm, can produce some sperm

Ejactory duct

Connects vas defrens to urethra and transports sperm
