Describe the prostate gland.
(75) 
VerifiedThe prostate gland is 2.5 cm long by 4 cm in diameter. The gland lies in front of the anterior wall of the rectum and 2 cm behind the symphysis pubis. It secretes a fluid that contributes to the seminal fluid and consists of a median lobe and two lateral lobes, separated by a shallow groove called the median sulcus. The seminal vesicles, which project like rabbit ears above the prostate, secrete a fluid that nourishes the sperm. Two bulbourethral glands the size of a pea are located inferior to the prostate on either side of the urethra.

The importance of screening for prostate cancer in males is discussed in Chapter 24.
