Genes that control percentage of body fat are also responsible for
circulating levels of testosterone in men, research published in the
latest edition of Clinical Endocrinology shows. The research shows a
23% overlap between the genes that control testosterone and those that
regulate body fat composition, suggesting that these two variables are
partly controlled by the same set of genes.
