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
