penis
A hormone secreted by the anterior pituitary that acts on the gonads
luteinizing hormone (LH)

pituitary gland
The fold of skin over the glans penis; the foreskin
prepuce

prostate gland
Period during which the ability for sexual reproduction is attained and secondary sex characteristics begin to develop
puberty
The thick secretion that transports spermatozoa (roots: semin, sperm/I, spermat/o)
semen
A double pouch that contains the testes (root: osche/o)
scrotum
A sac-like gland behind the bladder that contributes secretions to the semen (root: vesicul/o)
seminal vesicle
Cord attached to the testis that contains the ductus deferens, blood vessels, and nerves enclosed within a fibrous sheath
spermatic cord
Cell in a seminiferous tubule that aids in the development of spermatozoa; sustentacular (sus-ten-TAK-u-lar) cell
