Overview This 1991 instructional video, titled Sexuele Voorlichting — Puberty Sexual Education for Boys and Girls (English), is a period piece produced to teach adolescents about physical changes, reproduction, hygiene, and basic aspects of sexuality. Materials from this era combine medical information with social and moral framing common to the late 20th century. The video can be a useful historical resource and a starting point for discussion, but it should be used with awareness of dated language, gaps in inclusivity, and advances in knowledge since 1991.
