The Sex Files is a television program broadcasting on Discovery Channel Canada and was broadcast on CTV network stations after the watershed, due to its highly explicit discussion of the nature of sexuality issues and behavior, from genetics, reproduction, sexual orientation, puberty, etc. As one would expect of a show of its nature, it frequently featured nudity, but portrayed in a scientific manner for visually aid in learning, highly beneficial information on sexuality and the biology behind it. In Europe the show was called Sex Sense and featured a male narrator. The number of episodes and their titles were the same, but the episodes themselves were slightly different as the more explicit scenes were replaced. It aired on Discovery Channel Europe.

Starting with episode 41 (season 4), it is broadcast in high-definition.
