Hormone
Balancing for Women
by Karlis Ullis, M.D. and Joshua Shackman, Ph.D.
Many post-menopausal women in the United States are on some sort of
hormone replacement therapy program. However, I believe that hormone
replacement therapy the way it is commonly done may cause more harm than
good for many women. I prefer to use a personalized, case-by-case
approach for my female patients with the goal to restore a youthful
balance of sex hormones similar to what she had when she was in her
twenties or thirties.
Testosterone
I get more e-mails about testosterone replacement therapy for women
than any other single topic. Many women complain that their own doctor
is reluctant to put them on testosterone. Their doctor’s often fear the
big "T" and have many misconceptions about it. These women want to know
how to find a doctor knowledgeable about testosterone replacement
therapy for women. For these women, I have both good news and bad news.
The good news is that the pharmaceutical company
Unimed will soon be
coming out with the first transdermal testosterone gel for women
called ReLibra. Unimed will then begin an education campaign to inform
doctors around the country about the benefits of testosterone for women.
Having FDA approval for a testosterone product for women will
undoubtedly make testosterone replacement therapy for women more
acceptable among doctors everywhere. The bad news is that ReLibra won’t
be getting FDA approval for at least one or two more years.
Believe it or not, there are actually more women who need
testosterone replacement therapy than men. This is because even before
menopause, many women stop producing testosterone almost completely or
have very low levels of free testosterone and precursors such as DHEA
and androstenedione. Men, on the other hand, have their total and free
testosterone levels slowly go down, as they get older. Since
postmenopausal women tend to have miniscule testosterone levels, they
are often prime candidates for testosterone replacement therapy. If they
have low free testosterone levels and suffer from symptoms such as
fatigue, lack of libido, inability to lose weight, and depression, I
will consider testosterone as a front line treatment. Testosterone can
have pronounced effects on women, as it can radically improve their
health and outlook on life. I have seen women make dramatic improvement
in their exercise and diet programs. I have seen women overcome fatigue
and depression. I have also heard from many satisfied husbands that say
I have restored their wive’s sex drives to youthful levels. Even women
in their seventies have reported a return of sexual interest and
orgasms. Of course, a women wishing to go on testosterone or androgen
replacement therapy will have to first undergo a series of hormone tests
and screenings for various forms of cancer.
Once I have determined if a women is a candidate for testosterone
replacement therapy, I choose one of two treatment options. One option
is testosterone prohormones. This allows a, women, to get an occasional
boost before sex or before working out. The main testosterone prohormone
I use is 4-androstenediol (4-adiol or Androdiol). This is the most
potent prohormone for boosting testosterone levels. One female patient
measured her testosterone levels, which increased 400% after taking just
one quarter of a 12.5 milligram, cyclodiol lozenge. The main problem
with prohormones for women is that they generally come only in doses
appropriate for a male (100 to 250 milligrams per capsule), and not in
doses small enough for a, women (25 milligrams). Some companies sell
prohormones in powder or liquid sprays so the doses can be adjusted
properly for a, women. Another option is to use a pill cutter to slice
up a sublingual Cyclodiol lozenge, and use around 3 or 4 milligrams of
4-adiol sublingually at a time.
The other option I use is a compounded testosterone gel. Even though
ReLibra is not yet approved, I can still get a testosterone gel
specially formulated for a, women from a number of compounding
pharmacies. Transdermal gels are a good delivery system for testosterone
as it allows a slow, even release of testosterone into the bloodstream.
The testosterone bypasses the liver and testosterone levels are elevated
for about six hours. I usually start with a small dose of around .25
milligrams every other morning and increase as needed. It is always best
to start low and go slow.
Estrogen
Almost every postmenopausal woman is on some sort of estrogen
replacement therapy. I have been fighting a one-man war against the most
commonly prescribed drug used for estrogen replacement therapy, Premarin.
This is given out almost automatically to women upon menopause. I think
this is misguided for two reasons. One reason is that not every women
needs to go on estrogen replacement therapy. Estrogen can increase the
risk of breast cancer and also lead to unnecessary weight gain. Estrogen
is commonly given to livestock to fatten them up, so I find it silly
that it is given so frequently to a portion of the population that is
most at risk for obesity (yes, middle aged women are at a very high risk
of obesity). Natural plant phytoestrogens can give women many of the
benefits of estrogen, such as treating hot flash symptoms and lowering
the risk of heart disease. Phytoestrogens have the advantage over
estrogens in that they may actually lower the risk of breast cancer and
do not lead to weight gain. Women in Asia, who generally have a diet
richer in plant phytoestrogens and don’t use estrogen replacement
therapy as much, are both skinnier and have lower rates of breast
cancer.
Another way that I find the common form of estrogen replacement
therapy to be misguided is that the estrogen drug Premarin is almost
always used rather than natural bio-identical human estrogens. Premarin
is an orally administered drug made from the urine of pregnant horses (I
kid you not). Some of these horse estrogens are not found in the human
body, and likely have different effects than the natural human estrogens
estradiol, estrone, and estriol.
If estrogens are necessary then bio-identical estradiol should be
used transdermally to avoid weight gain and muscle loss. Oral is not the
best delivery system for estrogen and may actually be harmful. One study
(1) found that women on Premarin got fatter and lost muscle mass,
whereas women on transdermal estradiol had no significant change in body
composition. If Premarin is making women fatter while stripping away
muscle, it is clearly not a healthy thing for women to be taking. The
authors of this study believe that the worsening of body composition in
women who took Premarin may be because oral estrogens lower IGF-1
levels. IGF-1 is an anabolic hormone, and the women taking Premarin had
a measured drop in IGF-1 levels whereas the women on transdermal
estrogen measured no change in IGF-1 levels.
I generally try to get women to eliminate or minimize their estrogen
intake as much as possible. If they are successful at treating their hot
flashes with plant phytoestrogens alone, I do not encourage them to take
estrogen until they are much older and are at greater risk for heart
disease, osteoporosis, and mental decline. For those women who find that
phytoestrogens are not enough, I prescribe for them natural
bio-identical estrogen creams or gels. I favor estradiol over estrone
and estriol since these latter two forms of estrogen are possibly
transformed into more toxic metabolites (the bad catechol estrogens).
And I always encourage my female patients to discontinue taking
Premarin.
I have seen many women see great improvements in their weight loss
programs when they eliminate or minimize the use of estrogen. If you
have been working out and dieting properly for a long time, and just
can’t seem to make any progress, it may be due to the excess estrogen
you have been putting into your bodies.
Progesterone
Another issue I feel strongly about is the prevalence of synthetic
progestins that are given to women instead of natural progesterone. The
most commonly prescribed progestin is Provera, which is the brand name
for the synthetic drug medroxyprogesterone acetate. Provera is somewhat
androgenic like nandrolones, and women can become irritable and agitated
from using it. They can also experience other side effects such as acne.
On the contrary, natural progesterone can have a calming, relaxing
effect on woman.
The combination of estrogens and progestins can often cause
tremendous weight gain in women. Estrogen leads to fat storage, whereas
progestins can stimulate appetite. Also, progesterone can increase
cortisol levels, which will also cause fat gain and muscle loss. Even
worse, Provera may actually negate some of the positive effects of
estrogen in terms of preventing heart disease (2, 3), and can increase
the risk of heart disease and breast cancer in some populations of
women. Natural progesterone, on the other hand, may actually increase
the effectiveness of estrogen on preventing heart disease (2) or have a
neutral effect.
For women wishing to lose weight, I encourage them not to use any
progesterone at all and definitely not to use Provera. For women wishing
to reduce her risk of endometrial cancer, I may recommend small doses of
a natural transdermal progesterone gel. And I always discourage the use
of combined Premarin and Provera, which I believe is a travesty against
women and may be one of the major factors behind the obesity epidemic in
America.
Human Growth Hormone
Many female patients come to me wishing to go on human growth
hormone. The media has painted a very glamorous and unrealistic image of
growth hormone, often with imagery of a magical "fountain of youth"
inducing instant fat loss and youthful looking skin over night. The
truth, of course, is not so simple. Growth hormone, especially when
combined with testosterone, can in fact help lower body fat levels and
increase muscle mass. Some people due see their skin thicken and also
feel more energized. However, growth hormone is highly expensive and not
everyone notices a large effect from it.
Women in particular are more likely to want to go on growth hormone
than testosterone. Growth hormone is widely believed to be safer than
testosterone, although I don’t believe this is true (they are both safe
if used appropriately, dangerous if abused). The interesting thing is
that growth hormone is actually less effective in women than in men,
whereas the opposite is true with testosterone. Women need about double
the male dose of human growth hormone and do not have the robust result
seen in men regarding fat loss. Estrogen may block some of the
beneficial effects of growth hormone, and thus women often require a
much larger dose of growth hormone than men. Growth hormone is extremely
expensive already, so the larger doses often required for women can be
astronomically expensive for results that are often transient in many
cases.
I usually reserve growth hormone for women with genuine deficiencies
in growth hormone production as demonstrated by 24-hour growth hormone
level collections, growth hormone stimulation tests, or pituitary
disease. For some women who have had great results with their weight
loss programs but have reached a plateau, I might put them on a
temporary program of growth hormone replacement therapy to help them
burn off those last few pounds of fat. But I do warn women that this
therapy is highly expensive, and that they might find that they get less
than they expected for their money.
Conclusion
If you are a postmenopausal women, I encourage you to talk to your
doctor about natural, bio-identical hormone replacement therapy rather
than the standard Premarin/Provera combination. If your doctor is not
knowledgeable about natural hormones and testosterone for women, feel
free to show him or her this article or some of the references below. If
your doctor is still skeptical or unwilling to consider natural
alternatives to Premarin and Provera, you may want to consider switching
doctors. Some good physician referral listings are kept by, both the
Cognitive Enhancement Research Institute and the American Academy of
Anti-Aging Medicine. While I obviously can’t vouch for every doctor on
their lists, these doctors are far more likely to be sympathetic to the
kinds of treatments I have outlined in this article than your average
doctor.
Regardless of what choice of hormone replacement therapy you choose,
become informed. Don’t believe everything your doctor tells you or all
the promotional materials produced by the pharmaceutical companies.
Successful hormone replacement therapy must be personalized to meet your
goals and to match your individual health history. I also strongly
believe that your body will react best to natural, human hormones that
were present in your body before menopause rather than the synthetic and
often toxic hormones that are normally prescribed for women.
