5 Alpha-Reductase Inhibitors
A medication used to treat BPH and decrease the size of the prostate by blocking testosterone, an enzyme that acts on the male hormone to boost organ growth.
Abdominal Ultrasound
Ultrasound technology allows providers to examine a patient’s internal organs without resorting to surgery. A transmitter sends high frequency sound waves into the body, where they bounce off the different tissues and organs to produce a distinctive pattern of echoes. A receiver “hears” the returning echo pattern and forwards it to a computer, which translates the data into an image on a television screen. Because ultrasound can distinguish subtle variations between soft, fluid-filled tissues, it is particularly useful in providing diagnostic images of the abdomen. Ultrasound can also be used in treatment.
Acute Bacterial Prostatitis
A benign prostate disease caused by bacteria. It tends to come on suddenly and is often accompanied by a urinary tract infection.
Alpha-Adrenergic Receptor Blockers

Of no danger to health; not recurrent or progressive; not malignant.
Benign Prostate Disease
Nonmalignant conditions affecting the prostate gland.
Benign Prostatic Hyperplasia (BPH)
One of the most common prostate conditions, especially in men over the age of 50. The term benign means that the condition is not cancerous and the term hyperplasia means abnormal or unusual growth. The result of BPH is that the prostate becomes enlarged. The gland tends to expand in an area that doesn’t expand with it, causing pressure on the urethra, which can lead to urinary problems.
Benign Testicular Disease
Nonmalignant conditions affecting the testicles. Testicular trauma, testicular torsion, epididymitis, and hypogonadism are examples of benign testicular diseases.

Chronic Bacterial Prostatitis
A benign prostate disease. The condition is caused by bacteria in the prostate. It does not occur suddenly, but gradually gets worse over time. The only symptom a man may experience is a recurring bladder infection, with the same bacteria building up repeatedly.
Chronic Nonbacterial Prostatitis
Nonbacterial prostatitis is typically a chronic, painful disease. The symptoms (including chills, fever, pain in the lower back and genital area, body aches, burning or painful urination, and the frequent and urgent need to urinate) characteristically go away and then come back without warning. The urine and fluid from the prostate show no evidence of a known infecting organism, but the semen and other fluids from the prostate contain cells that the body usually produces to fight infection.
Chronic Pelvic Pain Syndrome
Persistent pain in the pelvic region, often linked to prostatitis.
Computerized Tomography, or CT Scans
Tests that use computers to create three-dimensional or cross-sectional images and linked to an X-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly.
A condition in which one or both testicles fail to descend normally.

A system of grading prostate cancer tissue based on how it looks under a microscope. Gleason scores range from two to ten and indicate how likely it is that a tumor will spread.
Hormonal Manipulation
The adjustment of the levels of testosterone, either by using specific medication or through surgery. Because prostate tumors require testosterone to grow, reducing the testosterone level is often effective in preventing further growth and spread of prostate cancer.
Human Chorionic Gonadotropin (HCG)
HCG is a protein in the blood that is often secreted as a result of testicular cancer. HCG can be used medically to treat male hypogonadism and cryptorchidism.
A condition that occurs when a man’s testicles do not produce an adequate supply of testosterone due to an abnormality in the testicles or a problem with the pituitary gland.

Spermatic Cord
A structure that secures the testicles at one end within the scrotum.
Stages of Prostate Cancer
A staging system to help determine the size and location of the cancer, and if the cancer has metastasized (spread) beyond the prostate.
