How Sex Works

Travelling inside the human body, we explore what’s really going on before, during and after sex
3 x 60' for BBC Three


This landmark series strips bare the science of sex and attraction like never before. Each episode is anchored in real human stories, as we follow selected characters on their own personal journeys. Their perspectives and experiences allow us to explore the science in an entertaining and involving way.

By travelling inside the human body we explore the physiological, neurological and psychological changes that happen before, during and after sex - and using Pioneer's trademark SFX, we illustrate the science of lust and the mechanics of sex itself. We learn how our bodies get ready for sex both physically and mentally, how the male and female orgasms work and what happens inside the body at the moment of conception itself.
