['To observe the effect of FSH and LH on the proliferation of human epithelial ovarian cancer cell.', 'Human epithelial ovarian cancer AO cells were incubated with follicle stimulating hormone (FSH) and luteinizing hormone (LH) (2U/L and 2.5U/L respectively). They were detected for proliferation by the use of the immunohistochemical technique and morphology.', 'The positive rate of proliferating cell nuclear antigen expressed in the cancer cell was increased significantly (p < 0.05) indicating its proliferation stimulating effect by FSH. The mitosis of cancer cells was increased by FSH and by LH (35%, 16% respectively).'] Do [ Gonadotropins stimulate the proliferation of human epithelial ovarian cancer cell ]?
