epididymis | tightly coiled tubule that houses sperm until mature - mature sperm stored in lower epididymis |
vas deferens | narrow tube that transports sperm from epididymis to ejaculatory duct |
prepuce | foreskin of penis |
glans penis | tip of penis |
seminal vesicle | glands that secretes and contributes thick yellowish fluid (seminal fluid) to semen (into vas deferens) |
prostate gland | surrounds base of urethra - secretes milky colored secretion during ejaculation which enhances motility of sperm - muscular action aids in expelling semen |

anorchism | absence of one or both testicles |
balantitis | inflammation of glans penis |
cryptorchidism | undescended testicle(s) - orchiopexy done to "fix" |
epispadias | congenital (birth) defect - urethra opens on the upper side of penis |
hydrocele | accumulation of fluid in scrotal sac |
hypospadias | congenital (birth) defect - urethra opens on the underside of penis |
orchitis | inflammation of the testes due to virus, bacterial infection or injury |
phimosis | tightness of prepuce of the penis - prevents it from being pulled back |

AIDS | deadly virus that destroys body's immune system by invading T-cells |
Kaposi's sarcoma | aggressive malignancy of blood vessels characterized by purple lesions on skin (AIDS) |
chlamydia | STD - bacterial infection that causes inflammation of cervix in women and urethra and epididymis in men |

radical prostatectomy | surgical removal of entire prostate gland as treatment for cancer |
suprapubic prostatectomy | surgical removal of prostate gland |
TURP - transurethral resection of prostate | surgical removal of a portion of prostate gland |
vasectomy | surgical cutting of vas deferens to prevent passage of sperm - male sterilization |
VDRL test | venereal disease research laboratory - serological test for syphilis - performed on blood serum |
