Polycystic ovary syndrome (PCOS) is the most common
endocrine disorder in women, affecting an estimated
five to ten million women of reproductive age. For women
trying to conceive a child, PCOS is a serious, common
cause of infertility - nearly half of all female factor
infertility cases can be traced to PCOS. New medical
insight into the disease has led to treatment options,
including ovulation medication, dietary changes and
surgery, which have proven successful and allow many
women to overcome PCOS and conceive a child naturally.
Women who undergo treatment for PCOS but are still unable
to conceive naturally often turn to assisted reproductive
technologies, including in vitro fertilization, and
experience high pregnancy success rates.
Women
who have PCOS often have a number of apparently unrelated
symptoms, including abnormal bleeding, infertility,
obesity, excess hair growth, hair loss and acne. The
condition likely has a genetic component and those affected
often have both male and female relatives with adult-onset
diabetes, obesity, high blood pressure and/or female
relatives with infertility, excess hair growth and menstrual
problems. Ultrasound reveals that polycystic-appearing
ovaries are another common symptom among women with
PCOS, but it is believed that PCOS may be present in
women who don't fit the traditional medical profile.
Physicians
have yet to come to an agreement on the preferred method
for diagnosing PCOS. It is estimated that only 25 percent
of women with PCOS have been diagnosed, largely due
to the fact that doctors and researchers have only recently
begun to understand the syndrome. Most physicians will
consider a diagnosis of PCOS after ruling out other
conditions such as Cushing's disease (overactive adrenal
gland), thyroid problems, congenital adrenal hyperplasia
or pituitary gland dysfunction.
After
reviewing a patient's medical history, the physician
will determine which tests are necessary, including
male hormone, fasting insulin and glucose levels along
with an ultrasound examination of the ovaries. If a
patient has irregular or absent menstrual periods, physical
exam clues will be factored in, including height and
weight, increase in facial or body hair or loss of scalp
hair, acne, discoloration of the skin under the arms,
breasts and in the groin area. Additional testing including
blood hormone levels, ultrasound and near-infrared absorptiometry
may also be performed to confirm the PCOS diagnosis.
Women
with PCOS are often at greater risk for other medical
conditions, so testing for blood lipids, diabetes and
abnormal blood clotting factors often follows the initial
diagnosis in selected cases.
Treatments
for PCOS have traditionally been difficult and expensive,
and have limited success when used alone. Today, through
a combination of medicinal therapy and dietary changes,
approximately 65 to 85 percent of patients with PCOS
achieve a regular menstruation cycle. For those patients
who are not trying to conceive a child but do want to
get their PCOS under control, the use of anti-androgen
medications such as birth control pills are successful
in managing symptoms.
Many
women with PCOS are able to conceive as a result of
treatments, which may include dietary counseling, ovulation
medications, ovarian drilling surgery and in vitro fertilization.
During ovarian drilling surgery, a laser fibre or electrosurgical
needle is used to puncture the ovary resulting in a
dramatic lowering of male hormones within days. Typically,
up to eighty percent of patients will benefit from ovarian
drilling treatment. Women who have failed to ovulate
with the use of ovulation induction medications, including
clomiphene and Metformin, will respond to the medications
when they are reintroduced to the system following ovarian
drilling.
Through
a combination of available treatments, many women are
able to conceive. For couples that are still unable
to conceive naturally following PCOS treatment, in vitro
fertilization (IVF) is most often the next step. IVF
success rates are higher and risk factors lower in patients
who have their PCOS under control.
The
diagnosis of polycystic ovary syndrome can be overwhelming
and confusing for many women. Your physician should
be committed to working through the diagnosis and treatment
plan step by step with you to put your mind at ease.
In many cases, women are comforted by the opportunity
to talk to other women who are going through the same
thing they are. There are a number of Web sites dedicated
to PCOS, including www.pcosupport.org and www.soulcysters.com,
for the approximately five to ten million women in the
United States who are affected by polycystic ovary syndrome.
