It was first "discovered" in 1935 by Doctors Stein and Leventhal and for many years was known as the Stein-Leventhal syndrome. Polycystic ovaries are common affecting 20-30 per cent of women and PCOS affects about 10 -15 per cent. The ovaries are a pair of female reproductive organs that produce eggs and female sex hormones. In individuals affected by PCOS hormonal inbalances in the production of oestrogens, progesterones and androgens lead to the presence of many small cysts in the ovaries. The cysts, usually no bigger than 8 millimetres each, are egg-containing follicles that have not developed properly and are arranged just below the surface of the ovaries. The symptoms of PCOS can include: irregular periods, or a lack of periods altogether

About Options Clomiphene Gonadotropins Intrauterine Insemination ... Treatment FAQs Polycystic ovary syndrome (PCOS), also called Stein-Leventhal Syndrome, is the most common endocrinologic disorder in women of reproductive age. Approximately 5-10% of reproductive age women have PCOS. This syndrome can have many symptoms. However, the two key components defining this disorder must include chronic anovulation (inability to ovulate an egg) and clinical hyperandrogenism (elevated male type hormones). The various symptoms of PCOS can be irregular or absent menstrual cycles, infrequent or absent ovulation, excess facial and body hair, male pattern balding, acne of face/back/chest, and infertility. Other findings can include an elevated FSH to LH hormone ratio, elevated levels of male hormones, multiple small cysts of the ovaries and elevated cholesterol. Some women with PCOS also suffer from other subtle endocrine abnormalities. One is insulin resistance, which affects sugar and fat metabolism, and may increase the long-term risks of heart disease, diabetes and high cholesterol. Insulin resistance (IR), the precursor state to diabetes, is present in 35-40% of women with PCOS, even if they are not overweight. Insulin resistance is diagnosed by blood testing, either as fasting glucose to insulin ratio, or as a complete glucose tolerance test (GTT). Long term follow up of women with PCOS reveals that up to 40% develop impaired glucose processing or diabetes by age 40. The prevalence of diabetes in women with PCOS is seven times higher than for the non-PCOS population. Excessive insulin production is thought to promote excess male hormone production, though the actual mechanism explaining this observation is still unclear.

Although its aetiology is complex, abnormalities of the ovarian cycle include failure of the normal cyclical changes in follicle-stimulating (FSH) and luteinizing (LH) hormones. As a result, the LH/FSH level is persistently elevated and ovarian follicles, chronically stimulated but unruptured, can be found in the subcapsular region of the ovaries. The ovarian fibrous stroma is increased, and the capsule hypertrophied. Imaging plays an important role in Stein Leventhal syndrome. While the diagnosis is clinical, imaging findings are helpful in the evaluation of the ovaries. Characteristically ovaries are enlarged, and because of the increased fibrous stroma, the characteristic findings include a fibrous centre, and large follicles at the periphery. The uterus is hypoplastic, and on either ultrasound or MRI, it exhibits an infantile appearance.

PatientPlus articles are written for doctors and so the language can be technical. However, some people find that they add depth to the articles found in the other sections of this website which are written for non-medical people. Polycystic Ovarian Syndrome Synonym = Stein Leventhal Syndrome The cause of this common, poorly-understood syndrome is uncertain. It causes menstrual dysfunction and signs of androgen excess. Initially classed as a primary ovarian dysfunction, it is now thought to reflect a more systemic disturbance in the metabolism of sex hormones. The condition is heterogeneous; sufferers may have classical clinical features but biochemically normal androgen levels. Insulin resistance and hyperinsulinaemia are often present. Physiological hormonal cycling is disrupted and the ovaries become enlarged by multiple follicles which have failed to rupture. The theca stroma cells surrounding the arrested follicles are markedly hyperplastic. However, the underlying endocrine disturbance can exist in the absence of polycystic ovaries. Current theories indicate that supra normal anterior-pituitary LH secretion leads to over stimulation of the ovarian theca cells, causing excessive androgen production (predominantly testosterone and androstenedione). Low FSH levels mean that ovarian granulosa cells fail to adequately convert these androgens into oestrogens, leading to ovulatory impairment and the development of unruptured cysts. Associated hyperinsulinaemia causes dyslipidaemia and increased plasminogen activation, thought to increase the risk of intravascular thrombosis. However, recent research has cast doubt on the presence of increased cardiovascular risk among sufferers of the syndrome once the effect of diabetes and obesity have been excluded.
