Key Info
  • Erections and wet dreams
  • Duration: 01:33
  • Presenter Robert Winston explains how erections are caused by a tightening of the blood vessels at the base of the penis meaning that more blood remains within it. There is footage of this tissue within the penis although the erection itself is not shown. The second half features an interview with a group of adolescent boys. They discuss how erections can be embarrassing and what happens when a wet dream occurs.

Ideas for use in class
  • This clip could be used to introduce the changes that boys go through at puberty. It explains erections and wet dreams. Why do they occur? It therefore lends itself very nicely to reviewing these at the end. Apart from the explanation of why an erection occurs, this clip is more focused on the emotions that can come with having erections and wet dreams and is therefore more appropriate to introduce or explain this aspect.
