Irregular Periods? It Might Be Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is the most common hormonal disorder in women, affecting 5-10% of the female population. It is characterized by irregular menstrual periods and infertility due to a lack of ovulation (release of an egg), and by signs of excess male hormones overproduced by the ovaries. Unwanted facial hair is sometimes a sign of excess male hormones. The symptoms usually start in adolescence, but can appear in her 20’s or 30’s. Many patients with PCOS are overweight. The ovaries are usually enlarged and contain multiple small cysts seen on an ultrasound exam. The small cysts are actually follicles (the small fluid sacs that house the eggs) that have not grown large enough to release their egg.

The actual cause of PCOS is unknown. It appears that women are genetically prone to this disorder. Female relatives of a patient with PCOS have a 50% chance of having it themselves. Certain lifestyle factors such as a high calorie, high carbohydrate diet and inadequate exercise may worsen many of the symptoms. PCOS causes a woman not to ovulate reliably. By not ripening an egg fully, her body fails to make an important female hormone, progesterone. Progesterone protects the uterine lining from overgrowth and from potentially cancerous changes.

A woman with PCOS is not necessarily going to exhibit all of the aspects of the syndrome. Some may be lean and others may not have any unwanted hair growth. The treatment for a woman with PCOS is directed toward alleviating her particular symptoms and limiting their risk for developing cancer of the uterus. The most common treatment for irregular periods is the birth control pill. “The pill” provides both estrogen and progesterone to regulate the menstrual periods and to protect the lining of the uterus from getting too thick. This effect allows for lighter periods and a reduced risk of cancerous changes to the lining. Another hormonal option is to give progesterone alone for 10-12 days each month, though this option doesn’t prevent unintended pregnancies.

The polycystic ovary makes more testosterone than usual. High testosterone levels can lead to excess facial hair and acne. One effective treatment is the birth control pill, which lowers testosterone levels so as to slow the formation of new thick hair follicles and lessen acne. It takes several months to see the improvement. Other medicines that block testosterone production such as spironolactone (Aldactone) can be prescribed. A prescription facial cream called Vaniqa is also available to help slow facial hair growth. Electrolysis and laser hair removal can also be used to temporarily remove the hair, once the testosterone levels are suppressed.

Many women with PCOS are relatively resistant to their own body’s insulin. The resulting high levels of insulin promote the storage of fat, making it hard to lose weight. A vicious cycle is created because overweight women make even more insulin and become even more resistant to it. Women with PCOS, particularly those who are overweight, are at an increased risk of diabetes and benefit most from losing weight. Changing her diet and exercising more are the usual recommendations for such a woman to lessen her symptoms and lessen her risks. Medications can be tried to possibly help control insulin and help with weight loss. One such medication is metformin (Glucophage), which can result in more regular menstrual cycles, ovulation, and pregnancy.

Infertility problems occur with PCOS because of the lack of ovulation. The most common treatment for inducing ovulation is to give the fertility pill clomiphene citrate (Clomid,). Eighty percent of patients will ovulate and half of those who ovulate will ultimately conceive within several attempts. There is a modest increase in the risk of having twins (7%) with clomiphene. Some patients do not respond to clomiphene and may require other therapies. One option is metformin to help the ovaries ovulate. Another option is to use fertility shots that contain follicle stimulating hormone (FSH). These shots directly stimulate the ovaries, but must be used with care because patients with PCOS can have an excessive response to these medicines and make too many eggs, increasing the risk of multiple pregnancies including the possibility of triplets or higher-order pregnancies. Therefore, these medicines must be monitored carefully by a trained Fertility Specialist (Reproductive Endocrinologist). Some patients will benefit from in Vitro Fertilization (IVF), where eggs are removed from the ovaries after stimulation with fertility shots and then introduced to sperm in a laboratory dish to create embryos. One or more embryos then can be placed into the uterus. Any remaining embryos can be frozen, if desired, to limit the risk if higher order multiple pregnancies (triplets or more) and for use in future fertility attempts.

In summary, there is hope for women affected by this common syndrome called PCOS to regulate their periods or to conceive a baby.
