This is why men tend to see increased body fat, lose their libido, and experience other undesirable changes as the years go on. Testosterone levels are not static; they change significantly throughout a man’s life. Production begins as early as the seventh week of embryonic development, setting the stage for sexual differentiation. During childhood, testosterone levels start to rise, leading to substantial changes during puberty. These levels peak during adolescence and early adulthood, when testosterone levels peak, marking a phase of optimal physical and sexual health.
