One would think that the general order of magnitude of the various hormone levels would have been made clear
in medical, nursing or undergraduate school. Obviously, women make lots of estrogen and men make lots of
testosterone, right? Women must certainly make much more estrogen than testosterone, right? We hardly hear
about androstenedione and dehydroepiandrosterone so, probably, there isn’t that much of them around. That
certainly must be true. WRONG!!
Women’s blood contains ten times as much Testosterone as Estradiol most of the time.
In the luteal phase of the cycle, a woman has about one hundred times as much Progesterone as
Estradiol.
Fifty-year-old men make about as much Estradiol as their wives.
Many men with erectile problems have too much estrogen, not too little Testosterone.
DHEA is the most common steroid hormone in the body and we don’t fully know what its function
is.


Lets take a look at the proportions of the various hormones to get a better feel for what is going on.
Interpretation of laboratory work and managing replacement and supplemental therapy require a basic
understanding of what is circulating in the serum and how to affect available hormone levels.
Unit Nomenclature:

Estradiol:

Estradiol is really powerful stuff, as you shall see. A normal young woman starts her menstrual cycle at about
20-40 pg/ml. Just before ovulation, common levels are 150-280 pg/ml in the serum. That is, she has 20-280
parts per trillion in her serum. A menopausal woman on HRT ranges from 20-100 pg/ml. A Vivelle Dot
0.0375 mg/day patch will achieve serum levels of about 25 pg/ml. The strongest patch, Vivelle Dot 0.1 mg/day
will give levels around 80 pg/ml. For many menopausal women, that is too high.
Progesterone:
Progesterone is much less powerful. A normal mid-luteal phase young woman has typical progesterone levels
of 10-20 ng/ml. That is 10-20 parts per billion in her serum. Progesterone 100 mg pills, capsules or tablets
given at bedtime will yield results on blood drawn the next day of about 1.5-8.0 ng/mg.
One ng/ml = 1,000 pg/ml.
So, a woman on HRT with typical values of:
Estradiol equal to 50 pg/ml
Progesterone equal to 5 ng/ml. Using the same units as Estradiol, Progesterone is 5,000 pg/ml
She has 100 times as much Progesterone in her serum as she does Estradiol. Now you know why there will
never be a bioidentical progesterone patch. It would have to be way too big. There is much more progesterone
in the blood than estradiol.
Testosterone:
Typical Testosterone at any age is between 20-70 ng/dl. Pay attention here, the lab changed the serum quantity
units. This is nanograms/deciliter. The nanograms are just like progesterone but the serum quantity has
changed from amounts per milliliter to deciliter, which is one hundred times bigger.
There are 10 dl in a liter. There are 1,000 ml in a liter.
50 ng/dl is only 0.5 ng/ml
So, lets go back to our typical HRT woman.
She has:

That means she has: One hundred times as much Progesterone as Estradiol

Ten times as much Testosterone as Estradiol.

But I thought women mostly have estrogen while men have testosterone? Wrong! But remember:

Estrogen is really powerful stuff!!

DHEA-S
DHEA and DHEA-S gradually decline with age. The “normal” values from the lab present such a huge range
as to be useless. I usually get DHEA-S because it is virtually entirely adrenal in origin and I use it as a measure
of adrenal output and health. There will be a separate paper on adrenal, but there are some things worth noting
here. Healthy women in their 20s run around 200 mcg/dl. I find that PCOS patients run higher levels. This has
been documented in other places, but I have never found a good explanation. Good levels for women around 50
years old run around 100 mcg/dl. Lets look at the units again.
One mcg or microgram is one part per million. To go back to the comparison with Estradiol:
So, back to our typical menopausal patient with an HRT Estradiol of 50 pg/ml: She has 20,000 times as much DHEA-S in her serum as Estradiol Cortisol, DHEA and DHEA-S are all in the same general range of concentration. They are 10,000 times
as concentrated in the serum as Estradiol.

Summary:

Lets take one final look at that typical healthy HRT patient.
Lab Value
Pico grams/ml
Relative Concentration

By the way, after having looked at values for about two thousand patients, the values I have chosen are typical
for women who are vibrant, healthy and active. These are what I consider the real Normal values.
Dropping male testosterone affects libido and erectile function, but so does rising estrogen. Abdominal fat
converts Testosterone into Estradiol in both sexes. Giving extra Testosterone to obese men may only make
matters worse.
It is amazing that laboratory science can directly measure Free T-3 at only three parts per trillion in serum. T-
3 is extremely powerful stuff.
