I think it's important when beginning
any discussion about the prostate is to
remind ourselves where the prostate is
and what it does this is a cross-section
of a man and here you can see the
bladder beneath it sits the prostate and
urine passes through out through the
bladder through the middle of the
prostate and then out through the penis
here is the back passage and that's
often why doctors will examine your
prostate through the back passage we can
feel the back surface of it very well
through there
the main function of the prostate is to
produce semen most of the semen that it
most of the fluid that is ejaculated
with orgasm is prostatic fluid there a
small amount of sperm produced by the
testes that's mixed in with this now
that we've seen where the prostate is
and what it does what I wanted to cover
next was urinary symptoms and this is
the first thing that often brings the
prostate to men's attention as they get
older most men do get urinary symptoms
as they get older and the commonest
course is non-cancerous enlargement over
the prostate gland or BPH for short the
symptoms are often caused by narrowing
of the outlet of the bladder if we look
at this next slide we can see the normal
opening through the center of the
prostate and how as men age they get
this non-cancerous enlargement in the
central part of the prostate that tends
to narrow the outflow channel and is
responsible for the urinary symptoms
that most men get as they age
