Materials and Methods: This cross-sectional study was conducted on 50 healthy young unmarried females in the age group of 20-25 years, having regular menstrual cycles. Reaction Time; Menstrual; Proliferative; Secretory; Sex Hormones INTRODUCTION The normal reproductive years of a female are characterized by regular rhythmical changes in the rates of secretion of the female hormones, and the resultant changes in the ovaries and other sexual organs. [1] This is governed by a well-coordinated and appropriately regulated changes in the levels of ovarian steroid hormones (estrogen and progesterone), which are responsible for producing the discrete responses in multiple tissues and organs. [3] Sex hormones are known to affect a whole gamut of CNS modalities such as neurite outgrowth, synaptogenesis, dendritic branching, myelination which ultimately affects the neural plasticity. [9] Hence, it can be postulated that the sensory motor performances could be modulated/altered during the different phases of menstrual cycle. [...]we envisaged this study to find out how and to what extent the sensory motor performances are being affected during different phases of menstrual cycle, by measuring the reaction time to visual (VRT)/auditory (ART) stimuli as a surrogate. MATERIALS AND METHODS The subjects for this study were selected from normal healthy unmarried females in the age group of 20-25 years, having regular menstrual cycles. The study was duly approved by the institutional ethical clearance committee. 50 subjects who satisfied the inclusion and exclusion criteria were selected, and informed consent was obtained from them. The subjects, who were included in the study, were...
