Granulosa cell proliferation is impaired in the Igf1 null ovary.

Abstract

Insulin-like growth factor-I (IGF-I) expression is highly correlated with ovarian follicular growth and granulosa cell proliferation in both pre-pubertal and mature murine ovaries. Igf1 gene deleted mice are infertile, with ovarian follicles arrested at an early stage of development. To elucidate the cause of follicular dysfunction in Igf1 null mice, this… (More)
