 The 1st of 2 Franz Josef Gottlieb films supposedly based on the works of Dutch gynecologist Van de Velde. A precursor to the more popular Schoolgirl Report pseudo-documentaries the Gottlieb "Van de Velde" films tried to take a scientific approach to various sexual discoveries within relationships. Taking the documentary route would allow Gottlieb (and other director s of the time) to introduce more graphic and risqué subject matter that was normally not shown in Germany during this time period.
