What are about 900 coiled tubes within the testes where spermatogenesis occurs?
seminiferous tubules
What is spermatozoa?
sperm (in semen)
What is sperm/o? Spermat/o?

What is a microscopic male germ cell that produces a zygote (fertilized egg) when combined with an ovum?
sperm
What does a sperm plus an ovum create?

What is the principal male sex hormone that stimulates the dev of male reproductive organs and secondary sex characteristics such as facial hair?
testosterone
What is the epididymis?
(epididym/o)
coiled tube attached to each testis that provides storage, transit, and maturation of sperm
What is the vas deferens (vas/o)?
duct/tube that carries sperm from epididymis to urethra
What are the seminal vesicles? (vesicul/o)
2 accessory glands located posterior to the base of the bladder that open into vas deferens; secrete a thick fluid that forms part of semen
What is the prostate gland? (prostat/o)
walnut-shaped gland that encircles proximal section of the urethra. prostate gland secretes fluid that aids in movement of sperm & ejaculation.
What is the semen?
semen is composed of sperm, seminal fluids, other secretions
What is the scrotum?
sac containing testes and corresponding epididymis, from which each vas deferens begins; scrotum is suspended on both sides of and posterior to penis.
What is the male organ of urine and coitus?
penis
What is the glans penis? (balan/o)
enlarged tip on the end of penis (head of penis)
prostatolith
stones in the prostate gland
balanitis
inflammation in the glans penis (head of penis)
orchitis
inflammation of the testes
prostatovesiculitis
inflammation of the prostate gland and seminal vesicles
prostatocystitis
inflammation of the prostate and bladder
orchiepididymitis
inflammation of the testis and the epididymitis
prostatorrhea
abnormal discharge from prostate gland
prostatic hyperplasia (benign)
excessive development in prostate gland that causes narrowing of urethra, which interferes with urine passage; symptoms incl: freq. of urination, nocturia, urinary retention, incomplete emptying of ballder
andropathy
disease specific to males only
anorchism
state of absence of testes (one or both)
balanorrhea
discharge from the glans penis (head of penis)
priapism
persistent abnormal erection
hydrocele
fluid filled sac around the testicle, causes scrotal swelling
phimosis
phimosis: tightness of the prepuce (foreskin of penis) that prevents retraction over plans penis (head); may be congenital or result from balanitis; circumcision is usual treatment
testicular torsion
twisting of the spermatic cord causing decreased bloodflow;
often presents during puberty and is considered a surgical emergency due to lack of blood flow
varicocele
varicocele: enalrged veins of the spermatic cord; may cause scrotal swellign
At what age does prostate cancer usually occur?
middle-aged men and older
At what age does testicular cancer usually occur?
men 15-35 yr of age
mastitis
breast inflammation
