The Female Hormone Panels
The ovaries are a very important part of the female reproductive organs. The ovaries are
located on the right and left side of the pelvic cavity next to the uterus. Each weighs about 15
grams. The human female is born with immature ovaries which gradually mature until the
start of menstruation signals a fully functional reproductive system.
The Cyclical Pacing of the Ovaries
The human ovary releases its hormones in a cyclical manner which is referred to as the
menstrual cycle. The average cycle is about 26-30 days. The timing and pacing of hormone
release is governed by GnRH, FSH & LH, hormones from the hypothalamus and pituitary
gland in the brain. The two major classes of ovarian hormones released during the menstrual
cycle are Estrogens and Progesterone, which are known as female steroid sex hormones.
The major and most active Estrogen released is Estradiol, while the major Progestin is
The female cycle has 3 physiologic phases :
1. The follicular phase starts with the onset of menstrual blood flow and is of variable length.
This phase is normally characterized by both low Estrogen and Progesterone output.
2. The ovulation phase is 1 to 3 days long and the human ovum (egg) is released in this phase.
This phase is characterized by high estrogen levels.
3. The luteal phase is rather constant in length, 12-14 days, and ends with menses. Compared
to the follicular phase, the luteal phase is characterized by high Progesterone concentrations
and a moderate increase in Estrogens.
Functions of Female Sex Hormones
Estradiol and Progesterone affect several target organs involved in a successful conception
and pregnancy. Additionally, these hormones maintain a number of secondary sexual
characteristics such as reduced body hair, soft skin texture, a higher voice pitch, possible
release of certain pheromones, etc..
Target Organs of Estrogen & Progesterone
1. The Uterus
Estradiol prepares the uterus for conception and produces a 3-5 fold increase in the
thickness of its inner lining, and also promotes uterine gland development and mucus
secretion. Progesterone causes a swelling of the uterine lining, an increase in glycogen (a
complex sugar) content, and an increase in the mucus secreted by the uterus. If conception
does not occur, the uterine lining is shed, resulting in the menstrual flow.
2. Fallopian Tubes
Sex hormones stimulate the fallopian tubes to move the egg toward the uterus. The fallopian
tubes also secrete nutritious fluids that nourish the egg, the sperm and ultimately the
embryo when fertilization occurs.
Estrogens promote the thickening of the vaginal lining and increase its secretions, which
makes the lining more resistant to infections.
Before puberty, the breasts grow only in proportion to the rest of the body, but under the
influence of Estradiol and Progesterone during puberty, the breasts develop to maturity.
During the menstrual cycle, excess Estradiol causes breast swelling and tenderness.
In the adult female, Estradiol and Progesterone play an important role in the inhibition of
osteoporosis and improve the incorporation of calcium and magnesium into bone. This is
why doctors prescribe Estrogen for menopausal women.
Estrogens cause the body to retain sodium which results in fluid buildup. Conversely,
Progesterone causes a loss of excess sodium and retained fluid. Before the period begins,
there may be a relative excess of Estrogen over Progesterone which commonly leads to
several of the PMS associated complaints.
Estradiol has stimulatory effects on liver proteins which may reduce thyroid hormone
availability and increases the risk for cardiovascular disease. Estradiol also slows the
process of liver detoxification of various harmful substances.
Estradiol can elevate blood sugar in certain susceptible individuals. Progesterone can
increase the appetite and has a general calming effect on the nervous system, especially at
What We Test
The FHP is a simple, non-invasive test. Eleven saliva samples are collected during specified
time periods throughout the menstrual cycle.
The FHP, for the first time in routine medical practice, will allow both patient and doctor to
actually view the profile of Estrogen and Progesterone simultaneously (See Figure 1).
Diagnostic guesswork is minimized, and hormonal balance evaluation and customized
treatment becomes a reality with the FHP.
In addition, we report the cycle average for Testosterone and DHEA.
The expanded eFHP also includes 5 FSH & LH measurements to see if brain control and
stimulation of the ovaries is optimal.
Applications of the Female Hormone Panel
1. Detection of Luteal Phase Defect
There are at least three luteal phase defect patterns which are characterized by a reduced
output of Progesterone that leads to Estrogen dominance. This imbalance is usually
associated with PMS, infertility, fibroids and other female hormonal problems and can be
readily detected by our panels.
2. Hormonal Imbalance and PMS
Many women suffer from hormonal imbalance in the Estrogen to Progesterone ratio. Our
panels can objectively evaluate the hormonal state with great accuracy which, in turn,
provides specific insights for appropriate intervention or treatment to relieve hormonal
imbalance and PMS related symptoms.
3. Customized Hormone Therapy
Presently, female hormone therapy is not individualized to the needs of each woman
because current diagnostic tests do not provide sufficient data. Consequently, most women
are empirically treated without regard to their individualized physiology and specific needs.
The FHP, for the first time, will allow a clinician to customize therapy to each female patient.
The FHP can also be used to detect & monitor the following:
* Functional infertility
* Influence of lifestyle (diet, exercise, etc.) on the cycle
* Menstrual problems originating in the brain
* Early pregnancy problems - spontaneous miscarriage
* Cycle irregularities, following the use of birth control pills
* Dysmenorrhea, i.e. painful and heavy periods
* Migraine headaches
* Endometriosis and cystic ovarian disease
* Early Osteoporosis
Advantages of the FHP
1. Convenience: requires no blood draws, therefore no repeated clinic visits and avoids the
inconvenience of the 24 hour urine collection.
2. Economy: the fee for the 11 sample test is less than that of 2 blood determinations or a
urine analysis for Estrogen and Progesterone.
3. Physiological Accuracy: research has demonstrated that the free hormone fraction
predominates in saliva. Hormones can be found free or bound to protein. The free hormone
fraction is very important to ascertain because it is the bioactive fraction that most
significantly influences living cells. The salivary female hormone levels correlate at 93%
with the free hormones in the tissues.
4. One or two blood determinations or a 24 hour analysis of urine for these hormones
cannot give an idea of the ovaries' hormonal productivity. The FHP? gives a good
approximation of the ovarian capacity over a whole cycle.
