Chapter 11 - Male Reproductive System Flashcards
motile
able to move
seminal vesicles
secrete material to help the sperm move
ejaculatory duct
leads to the prostate gland and the urethra.
prostatic fluid
provides a milky color to semen and helps the sperm move.
Identical twins
the result of one ovum’s splitting after it has been fertilized by a single sperm.
Fraternal twins
the result of two sperm fertilizing two ova.
Cowper’s gland/ bulbourethral gland
After William Cowper (1666–1709), English anatomist; One of two glands below the prostate that secrete a fluid to lubricate the inside of the urethra.
ejaculation
Expulsion of semen outside the body.
epididymis
Group of ducts at the top of the testis where sperm are stored.
flagellum
Tail at the end of a sperm that helps it move.
foreskin
Flap of skin covering the glans penis; removed by circumcision in many cultures.
glans penis
Sensitive area at the tip of the penis.
penis
Male reproductive part that covers the urethra on the outside of the body.
perineum
Area between the penis and the anus.
prostate gland
Gland surrounding the urethra that emits a fluid to help the sperm move and contracts its muscular tissue during ejaculation to help the sperm exit the body.
scrotum
Sac outside the body containing the testicles.
semen
Thick, whitish fluid containing spermatozoa and secretions from the seminal vesicles, Cowper’s glands, and prostate; ejaculated from the penis.
sperm
male sex cell that contains chromosomes.; spermatozoon (pl., spermatozoa)
spermatogenesis
Production of sperm.
testis (pl., testes)
One of a pair of male organs that produce sperm and are contained in the scrotum; testicles
testosterone
Primary male hormone.
vas deferens
Narrow tube through which sperm leave the epididymis and travel to the seminal vesicles and into the urethra.
andr(o)
men
balan(o)
glans penis
epididym(o)
epididymis
orch(o), orchi(o), orchid(o)
testes
prostat(o) prostate gland
prostat(o) prostate gland
sperm(o), spermat(o) sperm
sperm(o), spermat(o) sperm
AIH
artificial insemination homologous
BPH
benign prostatic hypertrophy
PED
penile erectile dysfunction
PSA
prostate-specific antigen
SPP
suprapubic prostatectomy
TUIP
transurethral incision of the prostate
TUNA
transurethral needle ablation
TURP
transurethral resection of the prostate
digital rectal exam (DRE)
the insertion of a finger into the rectum to check the prostate for abnormalities, tenderness, or irregularities.
prostate-specific antigen (PSA) test
Blood test for prostate cancer.
semen analysis
Observation of semen for viability of sperm.
urethrogram
X-ray of the urethra and prostate.
anorchism
Congenital absence of one or both testicles.
aspermia
Inability to produce sperm.
azoospermia
Semen without living sperm.
balanitis
Inflammation of the glans penis.
chancroids
Bacterial infection that can be sexually transmitted; results in sores on the penis, urethra, or anus.
cryptorchism
Birth defect with the failure of one or both of the testicles to descend into the scrotal sac.
epididymitis
inflammation of the epididymis.
epispadias
Birth defect with abnormal opening of the urethra on the top side of the penis.
hernia
Abnormal protrusion of tissue through muscle that contains it.
hydrocele
Fluid-containing hernia of the testis.
hypospadias
Birth defect with abnormal opening of the urethra on the bottom side of the penis.
impotence
Inability to maintain an erection for ejaculation.
infertility
Inability to fertilize ova.
oligospermia
Scanty production of sperm.
Peyronie’s disease
After Francois de la Peyronie (1678–1747), French surgeon; Abnormal curvature of the penis caused by hardening in the interior of the penis.
phimosis
Abnormal narrowing of the opening of the foreskin.
priapism
Persistent, painful erection of the penis.
prostatitis
Inflammation of the prostate.
seminoma
Malignant tumor of the testicle.
varicocele
Enlargement of veins of the spermatic cord.
transurethral resection of the prostate (TURP)
removal of a portion of the prostate through the urethra
transurethral microwave thermotherapy (TUMT)
the Prostatron, an FDA-approved device, sends computer-regulated microwaves through a catheter to heat and destroy selected portions of the prostate.
transurethral incision of the prostate (TUIP)
surgeon places one or two small cuts in the prostate. This relieves pressure without trimming away tissue.
trans-urethral needle ablation (TUNA)
burns away excess prostate tissue using radio waves. It helps with urine flow, relieves symptoms, and may have fewer side effects than TURP.
castration
Removal of the testicles.
circumcision
Removal of the foreskin.
epididymectomy
Removal of an epididymis.
orchidectomy
Removal of a testicle.
orchiectomy
Removal of a testicle.
prostatectomy
Removal of the prostate.
vasectomy
Removal of part of the vas deferens to prevent conception.
vasovasostomy
Reversal of a vasectomy.
transient vasoconstrictors
medications that cause temporary constriction of the blood vessels in the penis.
