1
Male Reproductive System

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.

2
Male Reproductive System

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.

3
Male Reproductive System

Testosterone

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.

4
Male Reproductive System

Seminiferous tubules

approximately 900 coiled tubes within the testes in which spermatogenesis occurs

5
Male Reproductive System

epididymis

coiled duct atop each of the testes that provides for storage, transit, and maturation of spermatozoa; continuous with the vas deferens

6
Male Reproductive System

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.

7
Male Reproductive System

Seminal vesicles

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.

8
Male Reproductive System

Prostate gland

encricles the upper end of the urethra. The prostate gland secretes a fluid that aids in ejaculation.

9
Male Reproductive System

Scrotum

Sac suspended on both sides of and just behind the penis. The testes are enclosed in the scrotum.

10
Male Reproductive System

Penis

male organ of urination and copulation (sexual intercourse)

11
Male Reproductive System

glans penis

enlarged tip on the end of the penis

12
Male Reproductive System

prepuce

fold of skin covering the glans penis in uncircumcised males (foreskin of the penis)

13
Male Reproductive System

semen

composed of sperm, seminal fluids, and other secretions

14
Male Reproductive System

genitalia (genitals)

reproductive organs (male or female)

15
Male Reproductive System

balan/o

glans penis

16
Male Reproductive System

epididym/o

epididymis

17
Male Reproductive System

orchid/o, orchi/o, orch/o, test/o

testis, testicle

18
Male Reproductive System

prostat/o

prostate gland

19
Male Reproductive System

vas/o

vessel, duct

20
Male Reproductive System

vesicul/o

seminal vesicle

21
Male Reproductive System

andr/o

24
Male Reproductive System

anorchism (an-OR-kizm)

state of absence of testis (unilateral or bilateral)

25
Male Reproductive System

balanitis (bal-a-NI-tis)

inflammation of the glans penis

26
Male Reproductive System

balanorrhea (bal-a-no-RE-a)

discharge from the glans penis

27
Male Reproductive System

benign prostatic hyperplasia (BPH) (be-NIN pro-TAT-ik hi-per-PLA-zha)

excessive development pertaining to the prostate gland (nonmalignant englargement of the prostate gland)

28
Male Reproductive System

cryptorchidism (krip-TOR-ki-diz-m)

state of hidden testes.

29
Male Reproductive System

epididymitis (ep-i-did-i-MI-tis)

inflammation of an epididymis

30
Male Reproductive System

orchiepididymitis (or-ke-ep-i-did-i-MI-tis)

inflammation of the testis and epididymis
