Comments: Deep-voiced men father more children

The article sounds quite interesting but mine is more of a question than a contribution as i am a bass singer in an acappella group.How do you incrrease the levels of Testosterone in the body or they are just natural hormones that cannot be reduced or increased?I need to know maybe i can improve the quality of my deep singing voice.
