Testis, or testicle (pl. testes, or testicles)
primary male sex organs, paired, oval-shaped, and enclosed in a sac called the scrotum. The testes produce spermatozoa (sperm cells) and the hormone testosterone.
sperm (spermatozoon, pl. spermatozoa)
The microscopic male germ cell, which when unite with the ovum, produces a zygote (fertilized egg) that with subsequent development becomes an embryo.
the principal male sex hormone. Its chief function is to stimulate the development of the male reproductive organs and secondary sex characteristics such as facial hair.
approximately 900 coiled tubes within the testes in which spermatogenesis occurs
coiled duct atop each of the testes that provides for storage, transit, and maturation of spermatozoa; continuous with the vas deferens
vas deferens, ductus deferens, or seminal duct
duct carrying the sperm from the epididymis to the urethra. The spermatic cord encloses each vas deferens with nerves, lymphatics, arteries, and veins. The urethra also conects with the urinary bladder and carries urine outstide the body. A circular muscle constricts during intercourse to prevent urination.
Two main glands located at the base of the bladder that open into the vas deferens. The glands secrete a thick fluid, which forms part of the semen.
encricles the upper end of the urethra. The prostate gland secretes a fluid that aids in ejaculation.
Sac suspended on both sides of and just behind the penis. The testes are enclosed in the scrotum.

erectile dysfunction (ED) (e-RIK-til dis_FUNK-shun)
the inability of the male to attain or maintain an erection sufficient to perform sexual intercourse (formerly called impotence)
scrotal swelling caused by a collection of fluid
a tightness of the prepuce (foreskin of the penis) that prevents its retraction over the glans penis; it may be congenital or a result of balanitis. Circumcision is the usual treatment.
persistent abnormal erection of the penis accompanied by pain and tenderness
prostate cancer (PROS-tat KAN-cer)
cancer of the prostate gland, usually occuring later in life. most common cancer in men, most are adenocarcinomas, arising from epithelial cells.
testicular cancer (tes-TIK-u-ler KAN-cer)
cancer of the testicle, usually occuring in men 15 to 35 years of age
Testicular torsion (tes-TIK-u-ler TOR-shun)
twisting of the spermatic cord causing decreased blood flow to the testis; occurs most often during puberty and often presents with a sudden onset of severe testicular or scrotal pain. Because of lack of blood flow to the testis, it is often considered a surgical emergency
enlarged veins of the spermatic cord.
surgical repair of the glans penis
excision of an epididymis
orchidectomy (or-kid-EK-to-me), orchiectomy (or-ke-to-me)
excision of the testis (bilateral orchidectomy also is called castration)
orchidopexy (OR-kid-o-pek-se), orchiopexy (OR-ke-o-pek-se)
surgical fixation of a testicle (performed to bring undescended testicle into the scrotum)
orchidotomy (or-kid-OT-o-me), orchiotomy (or-ke-OT-o-me)
incision into a testis
surgical repair of the testis
excision of the prostate gland
incision into the prostate gland and bladder
incision into the prostate gland to remove a stone
excision of the prostate gland and seminal vesicles
excision of a duct (partial excision of the vas deferens bilaterally, resulting in male sterilization)
creation of artifical opening between ducts
excision of the seminal vesicles
surgical removal of the prepuce (foreskin)
surgical removal of a hydrocele
radical prostatectomy (RP) (RAD-i-kel pros-ta-TEK-to-me)
excision of the prostate gland with its capsule, seminal vesicles, vas deferens, and sometimes pelvic lymph nodes; performed by a retropubic or perineal approach, or laparoscopically; used to treat prostate cancer
suprapubic prostatectomy (su-pra-PU-bik pros-ta-TEK-to-me)
excision of the prostate gland through an abdominal incision made above the pubic bone and through an incision in the bladder; used to treat benign prostatic hyperplasia and prostate cancer
transurethral incision of the prostate gland (TUIP) (trans-u-RE-thral in-SIZH-en PROS-tat)
a surgical procedure that widens the urethra by making a few small incisions in the bladder neck and the prostate gland. No prostate tissue is removed. TUIP may be used instead of TURP when the prostate gland is less enlarged.
transurethral microwave thermotherapy (TUMT) (trans-u-RE-thral MI-kro-wav ther-mo-THER-a-pe)
a treatment that eliminates excess tissue present in benign prostatic hyperplasia by using heat generated by microwave
transurethral resection of the prostate gland (TURP) (trans-u-RE-thral re-SEK-shun PROS-tat)
surgical removal of pieces of the prostate gland tissue by using a resectoscope inserted through the urethra. The capsule is left intact; usually performed when the enlarged prostate interfers with urination
transrectal ultrasound (TRUS) (trans-REK-tal UL-tra-sound)
an ultrasound procedure used to diagnose prostate cancer. Sound waves are sent and received by a transducer in the form of a probe that is placed into the rectum. The sound waves are transformed into an image of the prostate gland.
prostate-specific antigen (PSA) (PROS-tat spe-SIF-ik AN-ti-jen)
a blood test taht measures the level of prosate-specific antigen in the blood. Elevated test results may indicate the presence of prostate cancer or excess prostate tissue, as found in benign prostate hyperplasia.
semen analysis (SE-men a-NAL-i-sis)
microscopic observation of ejaculated semen, revealing the size, structure, and movement of sperm; used to evaluate male infertility and to determine the effectiveness of a vasectomy (also called sperm count and sperm test)
digital rectal examination (DRE) (DIJ-i-tal REK-tal eg-zam-i-NA-shun)
a physical examination in which the physician inserts a finger into the rectum and feels for the size and shape of the prostate gland through the rectal wall. Used to screen for BPH and cancer of the prostate. BPH usually presents as a unifrom, nontender enlargement, whereas cancer usually presents as a stony hard nodule.
