Summary Introduction
To review:
Identify the term that is used to describe the event when the penis becomes engorged with blood at the time of sexual excitement.
Introduction:
The prime function of the penis is to transport sperm into the woman’s reproductive system. The outer skin covering of the penis contains a shaft and it finishes in the expanded tip known as glans penis. Shaft is loose and folds toward the down side in order to form a sleeve known as prepuce or foreskin.

What causes an erection in the male penis?
a) Dilation (opening) of the smooth muscles around the veins leaving the penis
and constriction of the smooth muscles around the arteries entering the penis
creates engorgement of spongy tissue in the penis with blood.
O b) Dilation (opening) of the smooth muscles around the arteries entering the
penis and constriction (closing) of the smooth muscles around the veins
leaving the penis creates engorgement of spongy tissue in the penis with
blood.
c) Muscle contractions of the testes
d) Muscle contractions along the urethra
Sexual arousal results in a generally positive sympathetic response, e.g. increased heart rate, increased breathing rate and depth, etc. How is it, then, that erection can occur if sympathetic activity causes vasoconstriction and prevents blood flow into the vascular spaces of the penis?
Gross Anatomy of the Human Male Reproductive System
a) List the two main functions of the testis.
b) Why are the testes located in the scrotum rather than inside the ventral body cavity?
c) An enlarged prostate is associated with a number of disorders, including prostatitis and prostate cancer. Describe the diagnostic exam used to detect an enlarged prostate.
