-ary– pertaining to
includes both the external and internal genitalia
gonads
gon/o– seed (ovum or spermatozoon)
-ad– pertaining to
Testes are the gonads, or SEX GLANDS in a male. In a woman, it is the ovaries.

combining forms for the testicle
- testicul/o-
- didym/o-
- orchi/o-
- orch/o-
- test/o-
seminiferous tubules
semin/i– spermatozoon; sperm
fer/o– to bear
-ous– pertianing to
tightly coiled tubules that produce spermatozoa or sperm
spermatozoa
sper-mah-toh-ZOH-ah
spermat/o– perm
-zoon– animal
Just means “sperm”
interstitial cells
interstiti-/o– spaces within tissue
-al– pertaining to
secrete the hormone testostrone
testosterone
most abundant and biologically active of all the male sex hormones
lumen
matured sperm are continuously released into the lumen, which is the internal opening of the seminiferous tubules and carried by fluid into the epididymis
epididymis
long (20ft) , coiled tube that is attached to the outer wall of each testis.
epi– upon
-didymis– testes (twin structures)
inguinal
ING-gwih-nal
inguin/o– groin
-al– pertaining to
vas deferens
or
ductus deferens
VAS DEF-er-enz
a long duct that receives spermatozoa from the epididymis.
seminal vesicles
two elongated glands that form a V. They produce seminal fluid, which makes up most of the volume of semen.
ejaculatory duct
large collecting duct that holds sperms from each vas deferns and seminal fluid from the seminal vesicles.
prostate gland
round gland at the base of the bladder. not a part of the urinary system. It produces prostatic fluid.
prostatic fluid
milky substance that makes up some of the volume of semen. It contains an antibiotic substance that kills bacteria in the woman’s vagnia. It also carries substances that activates the ezymes in the head of sperm so that it can penetrate the woman’s ovum to fertilize it.
bulbourethral glands
bul-oh-yoo-REE-thral
bulb/o– like a bulb
urethro/o– urethra
-al– pertaining to
about the size of peas that are located on either side of the urethra. They produce thick mucus that makes up some of the volume of semen and neutralizes the acidity of any urine remaining in the urethra at the tiem of ejactulation.
balan/o-
means “glans penis”
corpora cavernosa
erectile tissue that is located along the upper surface of the penis
corpus spongiosum
Centered along the UNDERSIDE of the penis. The urethra is located within the corpus spongiosum.
adolesc/o–
the beginning of being an adult.
“adolescence”
suffix “-ence”– means “state of”
puberty
puber/o- growing up
-ty– quality or state
FSH
Follicle-stiumlating hormone
causes the seminiferous tubles to enlarge. Because these tubles make 80% of each testis, the testes themselves enlarge significantly during puberty.
spermatocyte
SPER-mah-toh-site
immature sperms. Each cell contains 46 at first, but then narrow down to 23.
LH
luteinizing hormone
LOO-tee-ih-ny-zing
number of sperm in semen
100-500 MILLION sperms!
ejaculat/o–
to expel suddenly
Ejaculatory
-ory–having the function of
coitus
same as “sexual intercourse”
pareun/o-
or
venere/o–
also mean “sexual intercourse”
such as “veneral disease”
scrot/o–
a bag.
scrotum
cryptorchism
crypt/o– hidden
orch/o– testis
-ism– process; disease from a specific cause
failure of one or both testicles to descend. This causes low sperm count and male infertility.
epididymitis
inflammation and infection of the epididymis. caused by bacterial urinary tract infection
epi– upon
didym/o– testes
-itis– inflammation
infertility
in– not
fertil/o– able to conceive a child
-ity– state; condition
may be caused by hormone imbalance of FSH or LH, or other reasons
