Steroids 65-81 leptin Homo sapiens 91-97 9329351-11 1997 In conclusion, these results indicate that sex steroid hormones, in particular testosterone, play an important role in the regulation of serum leptin levels. Steroids 47-63 leptin Homo sapiens 143-149 9329351-12 1997 The prevailing sex steroid milieu, not genetic sex, is a significant determinant of the sex difference in serum leptin levels. Steroids 19-26 leptin Homo sapiens 112-118
