Since Stein and Leventhal described the pathology of seven women without menstruation , with hirsutism and with an increase in the volume of the ovary in 1935 , the syndrome has been described under different clinical, analytical, histological and ultrasound criteria and this has greatly limited the evaluation of patients with this pathology since for a long time it was not known how we should define polycystic ovary syndrome.
The name PCOS is still an inappropriate name for a purely hormonal pathology, and it does not associate, although its name indicates it, cysts at the ovarian level. It is the most common endocrine disorder in women and affects 4-10% of women of reproductive age.
Ultrasound, patients with polycystic ovary usually associate a characteristic image of the ovary, generally enlarged and with multiple small follicles located in the periphery, at the subcortical level.
At the present time, a clear cause for the development of PCOS cannot yet be identified. We know that there may be a family association, since the sister of a woman with this pathology has a 40% greater chance of presenting this disease.
An important aspect of Polycystic Ovary Syndrome is that patients with this diagnosis associate a family history of diabetes and cardiovascular diseases, so information about it and the recommendation of healthy lifestyle habits are basic in the therapeutic management of these women.
