Clinical Evaluation of Effects of an Investigational Tampon on Vaginal Microflora

Subjects will be using investigational or control tampons during their menstrual period but these tampons are not intended to prevent, treat or diagnose an infection or other disease condition. A total 450 women will participate in this study at two study sites. Subjects will be randomly assigned to one of three tampon groups. The first group will test an experimental test tampon containing glycerol monolaurate (GML) on the cover. The second group will test an identical tampon, but without GML. The third group will not be issued study tampons but will be instructed to use their normal tampon brand. This study is intended to determine whether the effects of GML observed in the laboratory can be demonstrated in healthy menstruating women.
