The Effect of Menstrual Cycle on Singing Voice: A Systematic Review

SummaryObjectiveResearch has reported the difference in a woman's voice across the different stages of the menstrual cycle. A review of the studies in singers on the influence of menstruation on the singing voice will enable a better understanding of these changes.Methods/DesignA systematic literature search was carried out on PubMed, CINAHL, Scopus, Cochrane, and regional electronic databases. The keywords “menstrual cycle,” “voice change,” and “singer” were used in different combinations. Only those articles that discussed the effect of menstrual cycle on the singing voice were included in the final review.ResultsSix studies in the English language were identified and included in the review. Hormonal variations occur to a great extent during menstrual cycle, and these variations can influence the voice of singers. A great variability was found in the included studies. There are limited studies that have been carried out exploring the relationship between menstrual cycle and the singing voice.ConclusionEven though the studies included in the review point out toward the changes in the singing voice associated with menstrual cycle, there is a need for more studies to be carried out in diverse singing populations and in different outcome measures.
