Episode 26: The Prolific Penis

Why is the human penis so much larger than other primates’ penises? Why does it have such a funny and odd shape? In this episode, Kimberly educates her listeners about penile size, shape, and overall prowess. She introduces the concepts of Sperm Competition, Last Male Precedence, Semen Displacement Theory, Health Benefits of Semen, Refractory Period, The “Coolidge Effect,” and Semen Viscosity (relative to female promiscuity). Kimberly quotes research from leading evolutionary biologists to add context to her discussion of penile function and natures miraculous counter adaptations to infidelity.
