Comparison of transforming growth factor β1 concentrations in the ovaries of rats stimulated by human menopausal gonadotropin or recombinant follicle-stimulating hormone

The effects of two different gonadotropin preparations on TGF β1 concentrations in different localizations in the rat ovaries are comparable. It may be postulated that the luteinizing hormone (LH) content of hMG contributes little or nothing to the TGF β1 mediated angiogenesis.
