Specific penis anatomy terms.
I first want to thank PenisHealth for this nice penis picture.

Corona : this is a ridge of flesh joining the head of the penis and shaft.
Corpora cavernosa: two spongy bodies of erectile tissues on each side of the penis which become engorged with blood from arteries in the penis. When these tissues are filled with blood, the penis is in erection.
Glans: The glans is the head of the penis. The glans in uncircumcised men is usually covered by the prepuce. The glans like the corona are highly sensitive areas of flesh.
Urethra, meatus: The opening at the tip of the penis to allow the passage of both urine and semen.

scrotum: The scrotum is a sac that hangs behind and below the penis, and contains the testes, the male sexual glands. The scrotum's primary function is to maintain the testes at approximately 34 C, the temperature at which the testes most effectively produce sperm.
testes, testicles: The male sexual glands, the two testes within the scrotum produce sperm and testosterone. Within each testis is a kilometer of ducts called the seminiferous tubules, the organs which generate sperm. Each testicle produces nearly 150 million sperm every 24 hours.
epididymis: The epididymis is a 'holding pen' where sperm produced by the seminiferous tubules mature. The sperm wait here until ejaculation or nocturnal emission.
vas deferens: The ducts leading from the epididymis to the seminal vesicles. These are the ducts that are cut during the procedure known as vasectomy.

Or
I need results without spending too much time and money : I need MaleExtra.
Or
