30. The ductus deferens is a transporting tube which carries the mature sperm from
the epididymis to the prostate. Each tube enters the abdomen through the
inguinal canal. Each tube passes over a ureter to reach the back of the urinary
bladder and then down to the prostate gland. (para 8-15b)
31. Lying alongside each ductus deferens as it crosses the back of the bladder is a
tubular structure called the seminal vesicle. (para 8-15c)
32. The prostate gland is a chestnut-size gland that surrounds the first inch of the
urethra as it leaves the urinary bladder. It provides an additional fluid to be added
to the spermatozoa and seminal vesicle fluid. (para 8-15e)
33. The penis is the male organ of copulation. Passing through the penis is the
urethra. The penis has a central cylinder of erectile tissue called the corpus
spongiosum. Each end of this cylinder is bulb-shaped. The sensitive anterior end
is known as the glans. The corpora cavernosa are a pair of cylinders of erectile
tissue overlying the corpus spongiosum. When present, a covering of skin for the
glans is called the prepuce or foreskin. (para 8-15f)
34. The secondary sexual characteristics of males include growth of facial, pubic, and
chest hair; growth of the larynx to deepen the voice; and deposition of protein to
increase muscularity and general body size. (para 8-16)
