This
section addresses the role of sex hormones in maintaining libido and
sexual function. It discusses the manner in which a natural, or surgical
menopause, or medications may affect the sexual experience and provides
treatment options to restore sexual desire and function.
There
just doesn’t seem to be any way of getting around it. If you’re
menopausal and want to be at your optimum sexually, you need to replace
your hormones. Menopausal women, without the benefit of hormone replacement,
may be capable of enjoyable and satisfying sex. They may be capable
of great sex. But ultimately they loose the potential, as least as far
as sex is concerned, to be the best they can be.
A healthy lifestyle,
a positive attitude, exercise, a loving, giving, patient and understanding
partner …all are important. But, they can not substitute for adequate
hormone levels. It is clear and unequivocal; the integrity of the sexual
experience is dependent on sex hormones.
WHAT IS
DESIRE PHASE DISORDER?
Diminished hormone
levels interfere with optimum sexual function by their affect on sexual
desire and hormonally sensitive tissues.
Sexual desire, or
libido, consists of thinking about sex, fantasizing about sex, the development
of "sexual tension" and the awareness of a need for sexual
release. Some people may call feeling this way as being "horny".
It motivates us to initiate and participate in sex and if circumstances
require, search for a sexual partner.
Lack of, or diminished
sexual desire and loss of sexual motivation is sometimes referred to
as a "desire phase" disorder.
ARE THERE
DIFFERENCES IN HOW WOMEN ARE AFFECTED?
A postmenopausal
woman’s decrease in libido can range widely, from a barely noticeable
fall in sexual interest to a "sexual aversion" where the very
thought of being touched in a sexual context is repulsive. A number
of patients have told me, " I feel dead from the waist down",
to describe their lack of sexual interest. Several who were affected
to a lesser extent have shared, that although they really had no interest
in sex or in initiating sexual contact, once they were aroused by sexual
direct stimulation, the sexual activity was enjoyable and orgasm was
possible. I have found that some women evidence little concern over
their loss of libido and have no interest in restoring it. And this
is the very essence of not having a libido. Other women are devastated
by the loss and are interested in pursuing any reasonable treatment
that will allow them to regain their previous sexuality.
Unfortunately, many
women who express a concern about a lowered sex drive are referred to
a psychiatrist, counselor or psychologist, before even a cursory analysis
of their hormonal status and/or Hormone replacement therapy program
is considered. Certainly, stressful life events, health, psychological
or relationship problems influence libido, but these factors should
only be considered along with the menopausal woman’s hormonal
status.
WHAT CAUSES
A DECLINE IN SEXUAL DESIRE?
The decline in sexual
desire is likely a direct result of diminished sex hormone levels on
the brain itself. Although estrogen plays a part, the hormone that has
been shown to be most closely associated with sex-drive is testosterone.
The ovary, although
incapable of producing estrogen after a "natural" menopause,
may continue to produce significant amounts of testosterone for several
years. This is the reason why many women maintain a good sex-drive for
a considerable length of time. These testosterone levels provide additional
benefits to the naturally menopausal woman. Tissues of the body are
able to convert some of this circulating testosterone to estrogen. This
is the mechanism by which naturally menopausal women have fewer and
less severe symptoms and health problems usually attributed to sex hormone
deficiency. If a postmenopausal woman were to undergo removal of her
ovaries, this benefit would be lost.
WHAT ABOUT
PREMENOPAUSAL WOMEN WHO HAVE HAD A HYSTERECTOMY?
If the surgery is
performed prior to menopause and the ovaries are preserved and their
hormone secretion is unaffected, there may be no change in libido following
the post-operative healing period. In fact, some women experience a
post-surgical increase in sexual desire if prior to the surgery they
had been distracted by heavy bleeding or significant pelvic pain. There
is evidence, however that in this group of patients, ovarian failure
occurs up to 50% of the time within 3 years following the surgery. If
this happens, a diminished libido and other menopausal symptoms would
reflect the decline in hormone levels. Unfortunately, some physicians
are not aware of the frequency of ovarian failure following hysterectomy.
I have seen many patients who were in this category, who found it necessary
to come to my office because their physicians did not believe their
symptoms were possible or related to the surgery.
If the surgery is
performed prior to menopause and the ovaries are removed, the fall in
estrogen and testosterone levels is abrupt and severe. As would be expected
this type of surgically induced menopause almost always, results in
a dramatic fall in sexual desire.
IS THERE
ANYTHING ELSE THAT CAN CAUSE PROBLEMS WITH MY SEX DRIVE AFTER MENOPAUSE?
Significant health
problems, depressive illnesses, relationship problems and certain medications
can affect libido.
WHAT ARE
SOME OF THE MEDICATIONS THAT CAN CAUSE A PROBLEM?
A class of anti-depressants,
SSRI’s frequently depress both libido and potential for orgasm.
SSRI’s can do this so effectively in some patients that it is
used as a treatment for obsessive sexual preoccupation and premature
ejaculation.
I have had several
patients express a concern over a fall in their libido who had recently
begun treatment with an SSRI, not realizing that this was the cause.
Occasionally, delayed ejaculation or inability to ejaculate develops
in men who are not aware of this side effect and can lead to conflict
in a relationship if the couple doesn’t realize the medication
is responsible.
Orally administered
estrogen replacement medications and oral contraceptives are absorbed
by the gastrointestinal tract and reach the liver in a "bolus".
This so called "bolus effect", induces the liver to increase
its production of a substance, "sex hormone binding globulin"
(SHGB) which binds to circulating testosterone, leaving less "unbound"
or "free" testosterone available to maintain libido. This
is not well known and is often not recognized as a cause for a diminished
libido.
HOW
EFFECTIVE IS HORMONE REPLACEMENT THERAPY IN MAINTAINING LIBIDO?
It is very effective.
Most of the frequently used regimens of hormone replacement therapy
will maintain or restore libido. This will often take 4-6 weeks of treatment
and it helps if you are aware of this ahead of time.
Many women, especially
those, who have had a surgical menopause, will need a regimen that includes
testosterone replacement. This may include some women who choose an
oral regimen due its effect on SHBG levels as described above. Testosterone
can be given by most of the routes of administration, including injections,
gels and subcutaneous implants. When nothing else seems to work, subcutaneous
implants rarely fail to reestablish libido.
In the late 1980’s,
a television journalist who had interviewed me for some news segments,
which dealt with menopausal issues, called me with a request. He shall
remain unnamed for his own protection and journalistic credibility.
He wanted to know if I could find a woman for an on-air news segment
interview, "over 50", and "still having sex". After
a brief period, during which I was recovering from having been rendered
speechless, I told him that I was sure I could find someone. We made
arrangements for the interview to be shot at my office the following
week.
The television journalist
and his camera crew appeared at the appointed time. I introduced them
to June, an attractive, very sexual, woman of 80, who had been on hormone
replacement therapy for over 30 years. The interview was broadcast on
the evening news the following day to a potential audience of several
million. June was an educated and sophisticated woman who was anything
but shy. She informed the journalist and the viewing public, that she
enjoyed sex, had intercourse on average twice a week …and was
orgasmic.
I was chuckling
for days. On the way out she told me that she probably would have had
sex more often had she been getting along better with her husband. I
was pretty impressed with her. I was pretty impressed with both of them.
Yes …appropriate
hormone replacement therapy is very effective in maintaining libido.
Part
1: Sex and Menopause
Loss
of sexual desire and ability to participate in and enjoy sex is not
a normal part of aging. Dr Nosanchuk explains why a menopausal woman's
desire to have sex and her capacity to physically participate in sex
are both affected by her menopause...
