Scrotum
The pouch like structure located behind and below the penis
Penis
Acts as the male organ of copulation and urination, the orifice for elimination of urine and semen from the body
testes
provide the male sex hormone testosterone, the site where sperm formed and developed, androgen secreted by the testes
vas deferens or ductus deferens
acts as an excretory duct of the testes
seminal vesicles
2 leaf shaped organs, produces a slightly alkaline fluid that becomes a part of the seminal fluid,frutcose
epididymis
acts as a site for the maturation of sperm, it is located above the testis
prostate gland
donut shaped, that encircles the urethra, it secretes an alkaline fluid that aids in maintaining the viability of spermatozoa
Bulbourethral or Cowper’s glands
produce a mucous secretion before ejaculation, which becomes a part of the semen, they are pea shaped in sized, there are two of these
urethra
transmits urine and semen out of the body
sperm
is the only cell that can move, 50% of the sperms are killed on contact when ejaculated, a sperm consists of a head a body and a tail
ejaculatory duct
a small tube that joins the vas deferens to the urethra
spermatozoa
male reproductive cells
seminiferous tubules
- production of sperm 2. production of sex hormone
spermatic cord
travels through the inguinal canal and contains the lymphatic vessels, vas deferens, and nerve fibers, this leaves the testis and open up into the epididymis
puberty
a period of rapid change in the lives of boys and girls during which time the reproductive organs mature and become functionally capable of reproduction. In the male it begins at 12. As testosterone is released characteristics develop, such as pubic and axillary hair, increase in size of the penis and testes, voice changes, facial hair and erections and dreams
glans penis
cone shaped head of the penis, and is the site of the urethral oriface
foreskin
prepuce
smegma
the lubricating fluid that is secreted by the glands of the foreskin
copulation
sexual intercourse
cryptorchidism
where one or both of the testes fail to descend into the scrotum
phimosis
a condition of narrowing of the opening of the prepuce where the foreskin cannot be drawn back of the glands penis
epispadias
the urethra opens on the dorsum of the penis
hypospadias
the urethra opens on the underside of the penis
prostate gland
composed of glandular, connective and muscular tissue that lies behind the urinary bladder. It secretes and alkaline fluid that aids in maintaining the viability of spermatozoa
benign prostatic hyperplasia (BPH)
enlargement of the prostrate and occurs in older men
urethra
approx. 20 cm long and has 3 sections, the prostatic, membranous, and penile. it extends from the urinary bladder to the external urethral orifice at the head of the penis
anorchism
condition in which there is a lack of one or both testes
artificial insemination homologous (AIH)
means using the husband’s semen
artificial insemination heterologous
refers to using sperm from a donor other that the husband
aspermia
condition involving lack of sperm or failure to ejaculate sperm
azoospermia
condition in which the semen lacks spermatozoa
balanitis
inflammation of the glans penis
prostatism
any condition of the prostate gland that interferes with the flow of urine from the bladder
TURP
transurethral resection of the prostate where an endoscopic instrument is introduced directly through the urethra to the prostate and small pieces of the prostate gland are removed using an electrical cutting loop
castrate
removal of the testicles in a man or ovaries in the woman
circumcision
surgical procedure of removing the foreskin of the penis
condyloma
wartlike growth on the skin, most often seen on the external genitalia.
epispadias
congenital defect in which the urethra opens on the dorsum of the penis
erectile dysfunction (ED)
inability to achieve and maintain penile erection sufficient to complete satisfactory intercourse
euginics
study and control of the bringing for the of offspring as a means of improving genetic characteristics of future generations
gamete
mature reproductive cell of the male or female; spermatozoon or ovum
gonorrhea (GC)
highly contagious venereal disease of the genital mucous membrane of either sex
gynecomastia
pathological condition of excessive development of the mammary glands in the male
heterosexual
pertaining to the opposite sex; refers to an individual who has a sexual preference and relationship with the opposite sex
hydrocele
accumulation of fluid in a saclike cavity. One that occurs during prenatal development is caused by a failure of the closures of the canal between the peritoneal cavity and the scrotum
spermatocele
cystic mass in the epididymis
varicocele
dilation of pampiniform venous complex
hypospadias
congenital defect in which the urethra opens on the underside of the penis
mitosis
ordinary condition of cell division
oligospermia
condition in which there is insufficient (scanty) amount of spermatozoa in the semen
phimosis
a condition that can be present at birth in which there is narrowing of the opening of the prepuce and the foreskin cannot be drawn back over the glans penis
prostatectomy
surgical excision of the prostate
spermatogenesis
formation of spermatozoa
spermatozoon
male sex cell
syphilis
infectious venereal disease caused by Treponema pallidum; which can be transmitted sexually
vasectomy
surgical procedure in which the vas deferens are tied off and cut apart providing sterility by preventing transport of sperm out of the testes
A vasectomy does not affect the man’s ability to achieve orgasm, ejaculate, or achieve erections
Yeah!
testosterone toxicology
test performed on blood serum to identify the level of testosterone; increased level could indicate BPH and a decreased level could indicate hypogonadism
BPH
Benign prostatic hyperplasia
DHT
Dihydrotestosterone
ED
erectile dysfunction
GC
gonorrhea
HPV
human papillomavirus
PID
pelvic inflammatory disease
PSA
prostatic specific antigen
STDs
sexually transmitted diseases
TURP
transurethral resection of the prostate
VD
venereal disease
VDRL
venereal disease research laboratory
vesiculitis
Inflammation of the seminal vesicles
Varicocele
Enlargement and twisting of the veins of the spermatic cord
