placenta
organs of reproduction and their associated structures
genitalia
extends from scrotum to the area around the anus
male perineum
extends from pubic symphysis to the area around the anus
female perineum
produce sperm and deliver them into female body for union with ovum to create new life
male reproductive system
penis and scrotum
external male genetalia
sac-like structure that surrounds, protects, and supports testicles; suspended from pubic arch behind the penis and lies between the thighs
scrotum
two egg-shaped glands that produce sperm
testicles
site of sperm formation
seminiferous tubules
coiled tube at the upper part of each testicle; descends the length of the testicle, then moves upward to merge into vas deferens
epididymis
attached to each testicle; extends upward from epididymis; contains vas deferens plus arteries, veins, nerves, and lymphatic vessels for each testicle
spermatic cord
sensitive region at the tip of the penis
glans
retractable double-layered fold of skin and mucous membrane; prepuce
foreskin
located on the base of urinary bladder; opens into vas deferens; secrete yellow substance to nourish sperm cells
seminal vesicles
long, narrow continuation of each epididymus; leads upward and join the urethra
vas deferens
begins at vas deferens, passes through prostate gland, empties into urethra, reflex action pushes semen into urethra and out of the body
ejaculatory duct
lies under the bladder; surrounds end of urethra where vas deferens enters urethra; secretes thick, alkaline fluid into semen aiding motility of sperm during ejaculation
prostate gland
located just below the prostate gland; open into urethra; secrete pre-ejaculatory fluid helping flush any residual urine or foreign matter in urethra
bulbourethral glands
passes through the penis to the outside of the body
urethra
whitish fluid containing sperm
semen
process of sperm formation
spermatogenesis
inflammation of the glans penis
balantis
narrowing of the opening of the foreskin
phimosis
penis is bent or curved during erection
Peyronie’s disease
inability to achieve or maintain penile erection
erectile dysfunction
painful and persistent erection lasting 4 or more hours
priapism
male reaches climax too soon
premature ejaculation
absence of one or more testes
anchorism
inflammation of the epididymis resulting from a bacterial infection
epididymitis
fluid-filled sac in scrotum along the spermatic cord leading from the testicles
hydrocele
undescended testicle
cryptorchidism
cancer that begins in the testicles
testicular cancer
twisting of vas deferens and blood vessels leading into the testicle
testicular torsion
inflammation of testicles
testitis/orchitis
knot of widening varicose veins on one side of the scrotum
varicocele
normal range of sperm count
15-200 million per milliliter of semen
absence of sperm in semen
azoospermia
sperm count below 15 million/mL
oligospermia
presence of blood in seminal fluid
hematospermia
testing of freshly ejaculated sperm; determine the volume plus the number, shape, size, and motility of the sperm
sperm count
self-help step in early detection of testicular cancer
testicular self-exam
removal of the foreskin of the penis
circumcision
removal of one or both testicles
orchiectomy
repair of cryptorchidism
orchiopexy
removal of a portion of an enlarged being to relieve a varicocele
varicocelectomy
bilateral orchiectomy; removal or destruction of both testicles
castration
sterilizing procedure; blocking or cutting vas deferens
vasectomy
vasectomy reversal
vasovasostomy
allows a man to freeze his sperm indefinitely
cryopreservation
drugs such as Viagra; treat erectile dysfunction
PDE5 inhibitors
infections caused by bacteria or virus
STD/STI
infection with Chlamydia trachomatis; most common STD in the US
chlamydia
overgrowth of certain bacteria in the vagina
bacterial vaginosis
caused by herpes simplex virus
genital herpes
caused by human papillomaviruses (HPV)
genital warts
caused by infection with the Neisseria gonorrhoeae bacterium; infects the mucous membranes of the reproductive tract
gonorrhea
transmitted through infected bodily fluids
HIV
caused by the bacterium Treponema pallidum
syphilis
made of fat, connective tissue, and mammary glands
breasts
milk-producing glands that develop during puberty
mammary glands
carry milk from mammary glands to the nipple
lactiferous ducts
dark-pigmented area surrounding the nipple
areola
protect external genitalia and urethral meatus
labia majora and labia minora
female erectile tissue
clitoris
lubricate vaginal orifice
Bartholin’s glands
muscular tube extending from cervix to the outside of the body; lined with mucosa
vagina
pear-shaped organ with muscular walls and mucous membrane lining; located between urinary bladder and rectum
uterus
bulging, rounded part of uterus
fundus
body of the uterus
corpus
lower, narrow portion of the uterus
cervix
extend from upper end of uterus to the point near but not attached to an ovary; carry sperm upward from uterus toward descending mate ovum to allow fertilization
fallopian tubes
funnel-shaped opening into fallopian tube near the ovary
infundibulum
finger-like extensions that catch the mature ovum when it leaves the ovary
fimbriae
small, almond-shaped organs located in lower abdomen on either side of the uterus
ovaries
fluid-filled sac containing a single ovum
follicle
female gametes (eggs)
ova
