genitalia
are the organs of reproduction and their associated structures
perineum
is the external surface region in both males and females between the pubic symphysis and the coccyx
male perineum
tissue, that extends from the scrotum to the area around the anus
female perineum
tissue, that extends from the pubic symphysis to the area around the anus
external male genitalia
are the penis and the scrotum, which contains two testicles
internal male genitalia
include the remaining structures of the male reproductive system
scrotum
the sac-like structure that surrounds, protects, and supports the testicles; is suspended from the pubic arch behind the penis and lies between the thighs
testicles
known as testes, are the two small, egg-shaped glands that produce the sperm; develops within the abdomen of the male fetus and normally descend into the scrotum before or soon after birth
seminiferous tubules
sperm are formed within, of each testicle
epididymis
a coiled tube at the upper part of each testicle; runs down the length of the testicle , then turns upward toward the body, HERE. its narrows to form the tube known as vas deferens
spermatic cord
extends upward from the epididymis and is attached to each testicle,
sperm
known as spermatozoa, are the male gametes (reproductive cells)
semen
the whitish fluid containing sperm that is ejaculated through the urethra at the peak of male sexual excitement
spermatogenesis
the process of sperm formation
penis
the male sex organ that transports the sperm into the female vagina; penis is imposed of 3 columns of erectile tissue
glans penis
known as the head of the penis, it the sensitive region located at the tip of the penis
foreskin
known as the prepuce, a retractable double-layered fold of skin and mucous membrane that covers and protects the glans penis
vas deferens
known as the ductus deferens, are the long, narrow continuations of each epididymis, these structures lead upward and eventually join the urethra
seminal vesicles
are glands that secrete a thick, yellow substance to nourish the sperm cells; located at the base of the urinary bladder and open into the vas deferens as it joins the urethra
ejaculatory duct
which begins at the vas deferens, passes through the prostate gland and empties into the urethra
prostate gland
lies under the bladder and surrounds the end of the urethra in the region where the vas deferens enters the urethra
bulbourethral glands
known as Cowper’s glands, are located just below the prostate gland, one of these glands is located on either side of the urethra, and open int the urethra
urethra
passes through the penis to the outside of the body
urologist
a physician who specializes in diagnosing and treating diseases and disorders of the genitourinary system of males and the urinary system of females
balanitis
an inflammation of the glans penis that is usually caused by poor hygiene in men who have not had the foreskin removed
phimosis
a narrowing of the opening of the foreskin so it cannot by retracted (pulled back) to expose the glans penis; can be present at birth or become apparent during childhood
erectile dysfunction (ED)
known as impotence, the inability of the male to achieve or maintain a penile erection
Peyronie’s disease
known as penile curvature, a form of sexual dysfunction in which the penis is bent or curved during erection
priapism
a painful erection that lasts 4 hours or more but is either not accompanied by sexual excitement or does not go away after sexual stimulation has ended
premature ejaculation
a condition in which the male reaches climax too soon, usually before or shortly after penetration of the female
andropause
referred to as ADAM is marked by the decrease of the male hormone testosterone
cryptorchidism
known as an undescended testicle, a developmental defect in which one or both of the testicles fail to descend into their normal position in the scrotum
anorchism
the congenital absence of one or both testicles
epididymitis
is inflammation of the epididymis that is frequently caused by the spread of infection from the urethra or the bladder
hydrocele
a fluid-filled sac in the scrotum along the spermatic cord leading from he testicles
spermatocele
is a cyst that develops in the epididymis and is filled with a milky fluid containing sperm
testicular torsion
a sharp pain in the scrotum caused by twisting of the vas deferens and blood vessels leading into the testicle
testitis
known as orchitis, is inflammation of one or both testicles
varicocele
a knot of widening varicose veins in one side of the scrotum
azoospermia
is the absence of sperm in the semen
oligospermia
known as low sperm count, is a sperm count of below 20 million/mL; common cause of male infertility
hematospermia
is the presence of blood in the seminal fluid
sperm count
known as a sperm analysis, the testing of freshly ejaculated semen to determine the volume plus the number, shape, size, and motility of the sperm
testicular self-examination
a self-help step in early detection of testicular cancer by detecting lumps, swelling, or changes in the skin of the scrotum
circumcision
surgical removal of the foreskin of the penis
orchidectomy
surgical removal of one or both testicles
orchiopexy
the repair of an undescended testicle
varicocelectomy
the removal of a portion of an enlarged vein to relieve a varicocele
sterilization
any procedure rendering an individual (male or female) incapable of reproduction
castration
known as bilateral orchidectomy, the surgical removal or destruction of bath testicles
vasectomy
the male sterilization procedure in which a small portion of the vas deferens is surgically removed
vasovasostomy
known as a vasectomy reversal, a procedure performed as an attempt to restore fertility to a vasectomized male
sexually transmitted diseases (STDs)
known as sexually transmitted infections (STIs), are infections caused by either bacteria or a virus that affects both males and females
ophthalmia neoinatorum
condition is a form of conjunctivitis that is caused by the bacteria responsible for chlamydia or gonorrhea
chlamydia
caused by bacterium chlamydia trachomatis, the most commonly reported STD in US
bacterial vaginosis (BV)
a condition in women in which there is an abnormal overgrowth of certain bacteria in the vagina
genital herpes
caused by the herpes simplex virus type 1 or 2; symptoms include itching or burning before the appearance of lesions (sores) on the genitals or rectum
genital warts…caused by human papillomaviruses (HPV)
highly contagious. in male, the virus infects the urethra; in the female, it infects the external genitalia, cervix, and vagina
gonorrhea
a highly contagious condition caused by the bacterium neisseria gonorrhoeae. WOMEN..affects the cervix, uterus, and Fallopian tubes. MEN…affects the urethra by causing painful urination and an abnormal discharge ..also can affect mouth, throat, and anus
