Abstract
Objectives: Menstrual cycle is due to cyclic variations in the levels of various sex hormones.
This study was done to evaluate the influence of menstrual cycle on auditory and visual reaction times.
Material and Methods: This study was conducted on 50 healthy young females in the age group of 18-25 years, having regular menstrual cycles. The Auditory and Visual reaction time were measured by indigenously prepared reaction time software in menstrual, proliferative, and secretory phases.
Results: The average reaction times (in milliseconds) during the different phases of the menstrual cycle were as follows: ART = M - 198.28±14.688, P - 192.58±16.63, S - 185.47±13.27 and VRT = M - 246.13±8.21, P - 238.36±10.32, S - 232.87±6.38.
Conclusion: Both the ART and VRT were longer during the menstrual phase, whereas they were shorter during the secretory phase of the menstrual cycle which could be due to changes in the levels of female sex hormones.
Keywords: reaction time, auditory, visual, sex hormones.
