Stein-Leventhal Syndrome is a reproductive disorder affecting young
women. It is characterized by absent or abnormal menstruation, sterility,
mild signs of virilization, and sometimes obesity. The causes of the
syndrome are not understood, but may involve faulty production of
reproductive hormones. Therapy is often effective, but recurrences are
common.
Symptoms
The first symptoms of Stein-Leventhal syndrome usually appear shortly after
puberty and before age twenty, after menstruation has been normal or
irregular for some time. Menstrual flow becomes irregular and gradually
decreases over several months, until menstruation ceases. Sometimes, profuse
menstrual flow interrupts longer intervals of amenorrhea. Menstrual pain
occurs in about 20% of the patients.
Many patients consult a physician because of infertility or the
appearance of increased facial hair. Other signs of virilization include
voice changes and increased body hair with a "male" distribution, such as on
the chest. Obesity is a frequently associated problem.
Cysts are found directly under the surface of the ovaries. Other
pathological changes also occur. The uterus is often small and
underdeveloped.
Stein-Leventhal syndrome should be treated even when pregnancy is not
desired because erratic, or breakthrough bleeding can be a problem, and
because changes in the endometrium, the tissue lining the uterus that changes
regularly in the normal menstrual cycle, can lead to precancerous or
cancerous conditions.
Causes
The causes of Stein-Leventhal syndrome may vary from case to case, and are
usually poorly understood. Generally, the abnormalities are thought to occur
in hypothalamic, pituitary, or ovarian hormone production. Occasionally, a
tumor of the adrenal gland produces excessive amounts of androgenic hormones.
In all cases, the ovary fails to ovulate, and through a feed back mechanism,
becomes enlarged and full of cysts.
Affected Population
Young women are affected by Stein-Leventhal Syndrome.
Therapies: Standard
If a patient afflicted with Stein-Leventhal Syndrome wants to become
pregnant, ovulation and normal menstruation follows administration of
clomiphene in many cases; pregnancy occurs in about half of these patients.
If clomiphene is ineffective, gonadotropins may be tried. Should both fail,
ovarian wedge resection, or removal of the cystic portions of the ovaries,
can be performed. However, symptoms often recur.
If pregnancy is not desired, the ovary can be fully suppressed with low
dosage birth control pills or long acting progestins such as
medroxyprogesterone.
The investigational drug Flutamide is being tested in Stein-Leventhal
Syndrome as a treatment for the control of hair growth. For further
