title: [The ovary and insulin resistance].
abstract: Insulin resistance appears to be responsible of approximately half of the cases of polycystic ovaries, the other half being probably provoked by an anomaly of the stimulation of ovaries by an excess of LH. Nevertheless, it is likely that in most cases the two factors conjugate. The excess of androgen production by the ovarian stroma is one of the major symptoms of this disease. Today, however, the diagnosis is carried mainly with the assistance of ultra-sounds which, besides the increased ovarian volume, have permitted to discover an increased ovarian stromal vascularity. Two essential datas derive from the whole works: the increased frequency of ovarian hyperstimulation syndrome and the great number of metabolic complications which requires an endocrinological supervision. But the most recent works focus on the extension to all ages of this form of pathology: from the intra-uterine life to the post menopause; and on the hereditary character of this disease. The mystery remains concerning the mechanism of the favourable effect in clomifene resistant PCOS, of surgical and laparoscopic methods of ovulation induction to which it may be useful to resort after mature consideration. More recently the benefit at the administration of metformine has been confirmed by several works.
