Pulmonary Function Tests in Different Phases of Mensrual Cycle in Young Girls of 18-22 Years Age

Background : Women undergo hormonal changes especially during reproductive life. Menstrual cycle is an integral part of life of women. The changes in the level of estrogen and progesterone associated with menstrual cycle not only affects the reproductive system but also affects different systems including respiratory system.

Aim and Objectives: The aim of the study is to carry out pulmonary function tests during menstrual, proliferative and secretory phase of menstrual cycle in young girls.

Materials and Methods: The study was carried out in 50 healthy young girls of age between 18-22 years. Pulmonary function tests were done in all the three phases of menstrual cycle. The Analysis of Variance (ANOVA) was used to compare the means of various parameters in three phases of menstrual cycle.

Result: It was observed that FVC , FEV1, FEF25-75%, PEFR and MVV were statistically highly significant (p<0.01) in secretory phase as compared to menstrual phase and proliferative phase of menstrual cycle. These parameters are also statistically highly significant (p<0.01) in proliferative phase as compared to menstrual phase. The difference in FEV1%in different phases is statistically non significant.

Conclusion: Pulmonary function tests parameters were higher during secretory phase as compared to proliferative and menstrual phase. Main reason behind this could be the effect of progesterone on respiratory system.
