The production is noted for its amateur-style, documentary approach. It features a cast and crew of amateurs, centered around a "normal" family setting where the narrator, a boy named Els, introduces his family and discusses human anatomy. Key topics covered in the film include:
Information on menstruation, wet dreams, and secondary sexual characteristics like growth spurts and body hair.
Others criticize the film for what they perceive as the exploitation of underage nudity, questioning whether such explicit content is necessary for pedagogical purposes. One notable scene involves a 12-year-old boy and girl touching each other's bodies. Evolutionary Context in Belgium Sexuele voorlichting (Video 1991) - IMDb
