'Use It Or Lose It': A New Theory About Preserving Erectile Function After Prostate Surgery
Erectile dysfunction after
surgery to remove the prostate (radical prostatectomy) has traditionally
been attributed to nerve damage that theoretically should heal over time.
But it can take as long as two years for the nerves to recover enough for a
man to have an erection without the aid of drugs or devices. By that time,
other damage may have occurred, according to an article in the latest issue
of Perspectives on Prostate Disease.
The Harvard Medical School bulletin notes that when the penis is
flaccid for long periods of time, it is deprived of a lot of oxygen-rich
blood. Recent research suggests that this low oxygen level causes some
muscle cells in the penis's erectile tissue to lose their flexibility. The
tissue gradually becomes more like scar tissue, interfering with the
penis's ability to expand when it's filled with blood.
Therefore, the traditional advice given to men -- to wait for erectile
function to return on its own -- may not be adequate. Simply put, erections
seem to work on a use-it-or-lose-it basis. To prevent the secondary damage
that may occur if the penis goes too long without erections, researchers
now think it's better to restore erectile function soon after prostate
removal. Treatment options include using a vacuum pump device or taking
erectile dysfunction drugs by mouth or by injection into the penis.
According to Dr. Marc Garnick, editor in chief of Perspectives on
Prostate Disease and a Harvard oncologist, "Although the evidence
supporting this 'penile rehabilitation' isn't perfect, you may want to ask
your doctor about the options. Such early intervention may help increase
the odds that you will regain erectile function."
