Participación del factor de crecimiento insulinoide (IGF), en el síndrome de ovario poliquístico (SOP).

SUMMARY The partnership the insulin-like growth factor (IGF) in women with polycystic ovary syndrome (PCOS) is characterized by mechanisms underlying alterations in the GH/IGF-1, axis. In the pathogenesis exist a sinergism markedly enhanced between IGF-1 and insulin, and IGF-1 with LH to increase androgen production, causing a reduced IGFBPs and SHBG production, the resulting hyperandrogenism, within and ouside the ovary, may inhibitor follicular maturation and the biosynthesis of estrogen. At the present, the data suggests up to date paracrine, autocrine as well as endocrine actions in the ovary in normal conditions and the lost of this homeostasis can be followed by neuro-endocrine.
