Human reproduction is complicated and important, and it's going to take a four-part series for us to cover it. Today, we're kicking that off with the female reproductive system, starting with how sex hormones affect oogenesis and ovulation, continuing through how the ovarian and menstrual cycles mature and release oocytes, and creating a comfy uterine environment for a fertilized egg.

Sex is complicated for different reasons in different cultures. But, it's the entire purpose of life, so there's no reason to blush. In this episode of Crash Course Psychology, Hank talks about Kinsey, Masters and Johnson, Sexuality, Gender Identity, and Hormones, and even looks into the idea of why we have sex. There's a lot to go through here.
