| Female
Sexual Dysfunction - Treatment Options |
| Treatment
of female sexual dysfunction is gradually evolving as more
clinical and basic science studies are dedicated to evaluating
the problem. At the present time therapeutic options are limited
Aside from hormone replacement therapy which at the present
time is the only FDA approved treatment of FSD, medical management
of female sexual dysfunction remains in early experimental
phases. Studies are in progress accessing the effects of vasoactive
substances on the female sexual response. We will present
some of the currents conventional treatments and some unconventional
(off label) therapies we use at our center. |
|
Estrogen
Replacement Therapy |
| This
treatment is indicated in menopausal women (either spontaneous
or surgical). Aside from reliving hot flashes, preventing
osteoporosis, and lowering risk of heart disease in post-menopausal
women, estrogen replacement restores clitoral and vaginal
lubrication and sensation to levels close to those of pre-menopausal
women. Estrogens also have protective effects, which result
in increased blood flow to the vagina and clitoris. This helps
to maintain female sexual response over time. Without treatment
the following symptomatic complaints are common loss of desire,
decreased frequency of sexual activity, painful intercourse,
diminished sexual responsiveness, difficulty achieving orgasm,
and decreased genital sensation. |
|
DHEA |
| Dehydroepiandrosterone
is a male hormone produced by the adrenal gland and ovaries
and converted to testosterone and estrogen. DHEA, which depletes
with age, can be purchased over the counter in supplement
form. In one small study published in the New England Journal
of Medicine (Sept. 30, 1999), women who took 50 mg of DHEA
daily noticed a significant increase in sexual interest. Other
preliminary findings report encouraging results. However,
we recommend the use of DHEA only after evaluating blood levels
then replacing DHEA according to these blood levels.

|
Testosterone |
| Testosterone
is considered a crucial hormone for a healthy sex drive in
women as well as men. Studies show that a dramatic drop in
sex drive accompanies testosterone deficiency in women and
sexual responsiveness.1 One group of researchers also found
that sexual gratification in women directly correlated with
their testosterone levels.2
A more recent preliminary study from a team of Dutch researchers
finds that testosterone may also have specific physiological
effects on vaginal arousal. Women who were given testosterone
supplements showed markedly higher degrees of genital sensations
and arousal in response to visual stimulus, compared to those
given a placebo.3 Testosterone appears to stimulate neurons
in the brain that activate the nervous system - which plays
a major role in female sexual response. This treatment is
often used in combination with estrogen in menopausal women,
for symptoms of inhibited desire, dyspareunia, or lack of
vaginal lubrication.. Potential benefits of this therapy include
increased clitoral sensitivity, increased vaginal lubrication,
increased libido, and heightened arousal. In our center we
use testosterone in various delivery forms, which are custom
compounded for us. We use testosterone in Sublingual or transdermal
forms using minimal possible dose to raise serum testosterone
levels to the upper quintile of normal range. When used at
this physiologic doses side effects are keep at bay. *

Sildenafil |
| This
medication, commonly known as Viagra, serves to increase relaxation
of clitoral and vaginal smooth muscle and blood flow to the
genital area. Sildenafil may prove useful alone or possibly
in combination with other vasoactive substances for treatment
of female sexual arousal disorder. Several studies are already
published demonstrating efficacy of sildenafil for treatment
of female sexual dysfunction secondary to use of Antidepressants
(SSRI) drugs, in the post-menopausal population and on to
some degree in the pre-menopausal population with arousal
disorder.

|
L-arginine
|
L-arginine
This amino acid functions as a precursor to the formation of
nitric oxide, which mediates relaxation of vascular and non-vascular
smooth muscle. L-arginine has not been used in clinical trials
in women; however preliminary studies in men appear promising.
In our practice we use high dose oral L-arginine as an adjunct
with other therapy.
|
| Off
Label Therapeutic options |
|
Phentolamine |
Currently
available in an oral preparation, this drug causes vascular
smooth muscle relaxation and increases blood flow to the genital
area. This drug has been studied in male patients for the treatment
of erectile dysfunction. A pilot study in menopausal women with
sexual dysfunction Results indicated a mild, positive effect
of phentolamine across all measures of arousal, with significant
changes in self-reported lubrication and pleasurable sensations
in the vagina. In our practice we have had success with compounding
phentolamine into a topical preparation and applying it directly
to the clitoris
|
|
Yohimbine |
The
African tree active ingredient is yohimbine, which has proven
itself through clinical tests on both laboratory animals and
human male test subjects to increase sexual desire as well as
performance. Yohimbine is the only FDA-approved herbal medicine
for treating impotency. However the studies on use with females
have been few and with mixed results. At this time we limit
our use of yohimbine as and adjunct with other therapies and
for the treatment of antidepressant related sexual dysfunction.

Female
Sexual Dysfunction - Vasoactive Intestinal Polypeptides (VIP) |
There
is a growing body of evidence that women with sexual dysfunction
will commonly have physiologic abnormalities, Sexual dysfunction
occurs when during sexual stimulation abnormal arterial circulation
into the vagina or clitoris, usually from atherosclerotic vascular
disease, interferes with normal vascular physiologic processes.
Clinical symptoms may include delayed vaginal engorgement, diminished
vaginal lubrication, pain or discomfort with intercourse, diminished
vaginal sensation, diminished vaginal orgasm, diminished clitoral
sensation or diminished clitoral orgasm.. Vasoactive intestinal
polypeptide (VIP) is a polypeptide hormone of the gut and nervous
system, having a range of biological activities that includes
vasodilation,. VIP has been used successfully in the treatment
of erectile dysfunction. In a recent study it was shown that
vasoactive intestinal polypeptide (VIP) in females regulates
vaginal smooth muscle contractility and may play a role in increasing
blood circulation to the vagina and clitoris.

Topical
Alprostadil |
| Alprostadil
is a hormone like substance that is referred to as prostaglandin
E1, a known and potent vasodilator. Alprostadil has the power
to directly affect the tissue that comes in contact with. This
drug has been available for years for the treatment of erectile
dysfunction in males. In males it hasbeen used under the brand
name Caverject that is used as an injection into the tissue
of flaccid penis with fast acting results. Our as Muse which
is delievered via intraurethral pellets that are inserted into
the meatus (eye of the penis) with the aid of a minute insertion
stick. But a recent development has been the use of alprostadil
in a transdermal cream or gel. Currently alprostadil cream is
being sold in the far east under the trade name Befar and it
may soon be released later in some other countries under the
trade names Alprox and Topiglan. As for the United States Topiglan
manufacture by Macrochem Corp. is currently in phase III study.
Though most of the orginal studies and work have been done for
the use on men. It appears in some recent studies that Alprostadil
cream made be very useful for female sexual arousal disorder.
Since clitoral stimulation is being seen as an important aid
to sexual satisfaction in women. In one recent study ¾
of the women whom placed alprostadil topical reported clitoral
engorement and warm tingling sensation consistent with sexual
arousal with only minor side effects of mild burning in the
area placed which is transient. In the most recent study using
topical alprostadil they stated “enhancing subjective
and physiological arousal during visual sexual stimulation was
supported by patient ratings and physician assessments of vaginal
erythema and transudate volume.
At
the Center for Clinical Age Management we have been very successful
with the use to topical Alprostadil in a liposomal gel for
the treatment of female sexual aroual disorder. This prostaglandin
at time used alone and at times combined with phentolamine,
DHT or VIP.
