Seminal Glands
Located on posterior bladder surface;
Smooth muscle contracts during ejaculation;
Produces viscous alkaline seminal fluid

Plays a role in sperm activation
Bulbo-Urethral Gland
Produce thick, clear mucus during sexual arousal;
Lubricates glans penis;
Neutralize traces of acidic urine in urethra
Interstitial Cells
Produce androgens (testosterone)
Sustentocytes
Provide nutrients and signals to dividing cells;
Secrete testicular fluid into lumen for sperm transport
Myoid Cells
Squeeze sperm and testicular fluids out of testes
Ductus Deferens
Propels sperm from epididymis to urethra;
Vasectomy involves the ligation of this structure
