Flabby jowls and batwings for triceps not only make you look more feminine on the outside, but carrying that extra body fat makes you more ladylike on the inside, too. Since body fat is responsible for aromatizing testosterone into estrogen, the more fat you have on you, the more estrogen will be circulating in your body. Danish endocrinologists at Aarhus University recently tracked several changes in 43 men who underwent a 14-week diet and exercise program. As the pounds came off, and body mass index improved, estrogen levels dropped and testosterone started to climb. Additionally, sperm health and sperm quantity improved dramatically. By the end of the experiment, the subjects were not only leaner and more fertile.
