It all began 50 years ago with German gynecologist Dr. Judith Esser’s personal quest for a smarter tampon. Her fruitless search led her to develop her own tampon design, one that was easy to use, comfortable, and (most importantly) provided great protection. To this day, the o.b.® brand continues to retain a board-certified gynecologist and research teams to pursue Esser’s vision for creating safe, effective, and innovative options for women.
