PROSTATECTOMY. The doctor can palpate (feel) the
prostate gland through the wall of the rectum dur-
ing DIGITAL RECTAL EXAMINATION(DRE), which helps
detect prostate enlargement as well as abnormali-
ties that suggest other health concerns affecting
the prostate gland. Because the risk for prostate
cancer increases after age 40, DRE palpation of the
prostate gland becomes part of the ROUTINE MEDICAL
EXAMINATIONfor men age 40 and older.

prostate health Measures a man can take
throughout his life to maintain healthy function
of his PROSTATE GLAND. The prostate gland, which
wraps around the URETHRAat the base of the BLAD-
DER, produces the primary volume of SEMEN, the
fluid that carries SPERMout of the body during
EJACULATION, and the enzyme PROSTATE-SPECIFIC
ANTIGEN(PSA), which thins the semen to permit
sperm motility. The prostate gland functions
unobtrusively through most of a man’s life. In
early to mid-adulthood the most significant risk to
prostate health is INFECTION (PROSTATITIS), which
may be due to the spread of a sexually transmitted
disease (STD) such as GONORRHEAor may result
from non-STD causes.
In late midlife and beyond the prostate gland
begins to slowly enlarge, a natural aspect of aging.
Doctors call the enlargement BENIGN PROSTATIC
HYPERPLASIA(BPH). For about half of men over age
60 BPH becomes significant enough to constrict or
obstruct the urethra (the tubelike structure that
drains URINEfrom the bladder), causing symptoms
of urinary obstruction such as URINARY FREQUENCY
and hesitation. With increasing age the risk for
PROSTATE CANCER, the most serious health condition
affecting the prostate gland, also increases.
Dietary and lifestyle measures may slow the
progression of both BPH and prostate cancer.
Foods that support prostate health include
- SOY(soybeans, soy protein, tofu, tempeh)
- tomatoes and tomato-based foods such as
tomato sauce and tomato paste, which contain
LYCOPENE - pink grapefruit and watermelon, which also
contain lycopene - cruciferous vegetables (broccoli, cauliflower,
cabbage, kale), which contain sulforaphane and
other isothiocyanates, substances that appear to
help prostate gland cells fight cancer
A number of studies show the herbal remedy
SAW PALMETTOcan improve the symptoms of mild
to moderate BPH, apparently by shrinking the
prostate gland tissues. Some studies show a corre-
lation between high BODY MASS INDEX(BMI) and
more aggressive prostate cancers, and other stud-
ies demonstrate a lower risk for cancer overall (as
well as CARDIOVASCULAR DISEASEand DIABETES) with
healthy body weight and regular physical exercise.
In the United States, preventive health-care rec-
ommendations call for PSA BLOODlevel measure-
ments and DIGITAL RECTAL EXAMINATION(DRE) as part
of a man’s ROUTINE MEDICAL EXAMINATIONbeginning
around age 50. These tests may detect abnormal
function or size of the prostate gland that could be
early indications of BPH or prostate cancer.

MANAGEMENT.prostatectomy A surgical OPERATIONto remove
part or all of the PROSTATE GLAND. The prostate
gland encircles the URETHRA at the base of the
BLADDER. It produces the fluid that mixes with
SPERMto form SEMENand produces the enzyme
PROSTATE-SPECIFIC ANTIGEN (PSA), which facilitates
sperm motility after EJACULATION. Prostatectomy is
primarily treatment for PROSTATE CANCER and
BENIGN PROSTATIC HYPERPLASIA(BPH) that constricts
the urethra to the extent that it interferes with
URINATION. Removal of the prostate gland ends a
