Abstract
Objective
To determine whether menstrual cups are a viable alternative to tampons.
Design
Randomized controlled trial.
Setting
Prince George, Victoria, and Vancouver, BC.
Participants
A total of 110 women aged 19 to 40 years who had previously used tampons as their main method of menstrual management.
Intervention
Participants were randomized into 2 groups, a tampon group and a menstrual cup group. Using online diaries, participants tracked 1 menstrual cycle using their regular method and 3 menstrual cycles using the method of their allocated group.
Main outcome measures
Overall satisfaction; secondary outcomes included discomfort, urovaginal infection, cost, and waste.
Results
Forty-seven women in each group completed the final survey, 5 of whom were subsequently excluded from analysis (3 from the tampon group and 2 from the menstrual cup group). Overall satisfaction on a 7-point Likert scale was higher for the menstrual cup group than for the tampon group (mean [standard deviation] score 5.4 [1.5] vs 5.0 [1.0], respectively; P = .04).
Approximately 91% of women in the menstrual cup group said they would continue to use the cup and recommend it to others. Women used a median of 13 menstrual products per cycle, or 169 products per year, which corresponds to approximately 771 248 400 products used annually in Canada. Estimated cost for tampon use was $37.44 a year (similar to the retail cost of 1 menstrual cup). Subjective vaginal discomfort was initially higher in the menstrual cup group, but the discomfort decreased with continued use. There was no significant difference in physician-diagnosed urovaginal symptoms between the 2 groups.
Conclusion
Both of the menstrual management methods evaluated were well tolerated by subjects. Menstrual cups are a satisfactory alternative to tampons and have the potential to be a sustainable solution to menstrual management, with moderate cost savings and much-reduced environmental effects compared with tampons.
