Episode notes
Richard Richter's 1909 Loop Began Modern IUD Literature
- The first published IUD description (1909, Richard Richter) used silkworm gut loops and a bronze wire to irritate the uterus and prevent implantation.
- Richter reported up to four years' retention and return to fertility after removal, but without robust data.
Grafenberg Ring Pioneered Modern Ring Designs
- Ernst Grafenberg developed a flexible intrauterine ring in the 1920s–30s that influenced later designs, but his Jewish identity and Nazi repression limited dissemination.
- Grafenberg's ring had low reported failure rates but faced professional denouncements.
Ota Ring Blended Folklore And Grafenberg Design
- Japanese physician Tenrei Ota created the Ota ring combining a wire rim and a central gold ball, inspired by animal anecdotes and the Grafenberg ring.
- The device's adoption was later suppressed by Japanese bans in the 1930s.
