The rationale for
keeping the ovaries, would be to maintain a source of your own sex hormone
production. It is possible that your ovaries may continue to produce
adequate amounts of estrogen and testosterone until the time you would
have had experienced a natural menopause. The normally functioning postmenopausal
ovary also may be capable of producing significant amounts of testosterone
for several years following menopause. Testosterone is the hormone is
closely associated with energy levels, lean body mass, libido and sexual
function. In addition, if testosterone levels are present, some of it
may be converted to estrogen by a process called, "aromatization".
This may be the reason that naturally menopausal women are known to
have less severe menopausal symptoms and fewer negative health consequences.
as contrasted to women who have had their a surgical removal of benefit
in reducing the severity of menopausal symptoms.
However it should
be noted, there is an increased incidence of ovarian failure following
hysterectomy. This is discussed in some detail in the section of the
web site, Ovarian Failure
Following Hysterectomy.
Is there
any reason I might want my ovaries removed?
There is always
the argument that removing the ovary prevents the possibility of ovarian
cancer. A woman has a 1 in 70 chance of developing cancer of the ovary
during her lifetime. Due to a lack of symptoms initially, the presence
of ovarian cancer is typically not discovered to a late stage and for
this reason is often fatal. The peak incidence of ovarian cancer is
between the ages of 70-80.
There is a type
of ovarian cancer that is hereditary. The mutated genes responsible
for most hereditary ovarian cancers have been identified, (BRCA1, BRCA2).
There is a blood test available to identify carriers of this gene. Woman
who are identified as having the mutated gene should consider the option
of ovarian removal and non-carriers can be assured that their risk of
ovarian cancer is not increased.
I'm concerned
about the possibility of ovarian cancer, but I want to keep my ovaries.
Is there anything I can do?
If you were to decide
to keep your ovaries, there are strategies that can be and I believe
should be implemented by all women, to increase the possibility of discovering
a developing ovarian cancer at an early stage and increase one's chance
of surviving this disease. (1)A yearly pelvic ultrasound, preferably
transvaginal and utilizing one of the more advanced ultrasound technologies.
(2)A yearly CA 125 blood test. (3)A yearly pelvic examination. (4)An
immediate visit to the doctor for any persistent abdominal symptoms.
What if
I have endometriosis?
If the reason for
your hysterectomy is endometriosis, there is an additional consideration
for removing the ovaries. There is research that documents that patients
who were treated for endometriosis with ovarian conservation were at
a substantially increased risk of recurrent symptoms and a frequent
need for reoperation, as compared to those who had ovarian removal.
Is there
an age that you recommended that your patients who needed a hysterectomy
have their ovaries removed?
If I was asked,
I usually recommended that patients 45 and over consider having their
ovaries removed, assuming they planned to use HRT. Not all women respond
well to the more frequently used HRT regimens. Accordingly, one important
factor in the decision making process is whether you have a physician
resource available who is knowledgeable about menopausal issues and
skilled in a wide range of HRT treatment options. This is discussed
in the section of the web site, Hysterectomy.
If I have
my ovaries removed, should I go on HRT?
I would certainly
suggest that. I believe that women who are experiencing hormonal deprivation
should consider appropriate HRT as a first line strategy for health
and quality of life maintenance. Surgically menopausal users of HRT
are known to have a lesser incidence of osteoporosis, cardiovascular
disease and death, than non-users. In addition surgically menopausal
women who are without the benefit of HRT, may experience severe and
life altering menopausal symptoms.
What are
the risks of going on HRT?
I believe, assuming
that HRT is given in a physiologic manner and in my view means a non-oral
route of administration, specifically transdermal or subcutaneous, in
doses that result in physiologic blood levels of estradiol and testosterone,
the risks would be no greater than having your own source of hormone
production. I prefer to prescribe non-oral regimens of estradiol and
testosterone, utilizing non-oral routes of administration. This has
the advantage of avoiding the "bolus, first pass" liver consequences
and enzyme alterations associated with oral administration of hormones.
Oral administration of HRT, is the most commonly used route of sex hormone
delivery used in the world and it has been proven to be effective and
safe for most women. However, my sense is that non-oral routes of administration
are potentially even safer and more effective. There is more about this
in the section of the web site, Methods of HRT.
I would
like to share a scenario I often saw repeated in various forms.
I would be speaking
to a menopausal woman from whom I had just taken a detailed history.
She had related that she smoked 1 1/2 packs of cigarettes daily, drank
3-5 cocktails daily, took over-the-counter and prescription diet medication,
did no exercise, was 30 lbs overweight, consumed a high fat diet, had
undergone 3 cosmetic surgeries requiring an anesthetic, visited a tanning
salon 3 times a week, did not wear a seat belt while driving, did not
have regular pelvic exams or mammography and was having unprotected
sex.
After I had discussed
HRT at length, including the weight of evidence that HRT is an effective
health maintenance strategy, she would look at me and say, "but
I am afraid of the risks of HRT!"

Ovarian Failure Following
Hysterectomy
Hypothetically, if you’re premenopausal and still have your ovaries
following a hysterectomy, one would expect continued production of ovarian
sex hormones. Unfortunately, it has been well documented that this is
often not the case. A number of medical studies have documented that
ovarian failure occurs frequently in retained ovaries following a hysterectomy
