Work by relaxing the muscles at the neck of the bladder and in the prostate .
This chapter focuses on infections of the male urethra, epididymis, testis, and prostate .
The prostate is a small gland about the size of a walnut situated at the base of the bladder.
The prostate gland encircles the urethra adjacent to the neck of the bladder and is formed of 30 to 50 tubuloalveolar glands grouped into lobes.
Seminal fluid continues to be produced normally by the prostate gland and seminal vesicles.
The section of the urethra that traverses the prostate gland is called the prostatic urethra.
The prostate gland is just below the bladder, and infections can pass both ways along the urethra.
The prostate gland makes a fluid that provides nutrients for sperm.
The accessory glands, including the seminal vesicles and the prostate gland , provide fluids that lubricate the duct system and nourish the sperm.
Because the prostate gland sits below the bladder, the disease affects its functions.
