Research Abstract

It had been well known that LH had an important role in ovarian angiogenesis. In this study, we demonstrated that not only LH but also ligand-specifically regulated LH receptor(LHR) might exert regulatory effects on temporal and spatial regulation of angiogenesis in the ovary. To modulate the LHR expression might be a new strategy for ovarian pathology stemmed from abnormal angiogenesis, such as PCOS and OHSS.
