Effect of Menstrual Cycle on Absolute Platelet Count among Female Students of Lead City University, Ibadan, Oyo State . International Blood Research & Reviews. 2025 Mar; 16(1): 18-242321-7219https://imsear.searo.who.int/handle/123456789/248301Introduction: Hormonal changes associated with menstruation, or the periodic shedding of the uterine lining, can affect a number of physiological measures, including the absolute platelet count. The impact of menstruation on platelet counts in female students at Lead City University in Ibadan is investigated in this study. Aim/Objective: The purpose of this study is to examine how menstruation affects platelet counts and determine whether there are notable differences across the various stages of the menstrual cycle. Methods: One hundred participants, fifty of whom were menstruation and fifty of whom were not, participated in a descriptive cross-sectional study. A Neubauer counting chamber was used to measure platelet counts, and SPSS version 23 was used to analyze the results. Results: Participants who were menstruation had a substantially lower mean platelet count (200.66 ± 30.73/cu.mm) than those who were not (255.42 ± 53.52/cu.mm) (p < 0.01). Nevertheless, no meaningful correlations between platelet counts and particular menstrual days or lengths were discovered. Conclusion: Young women's platelet counts are considerably reduced by menstruation. These results emphasize the significance of taking menstrual status into account while performing hematological evaluations and the necessity of more investigation into the underlying mechanisms.Hematologymenstruationhormonal changesmenstrual cycleplatelet countJournal ArticleIndiaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, NigeriaDepartment of Medical Laboratory Science, Faculty of Basic Medical and Health Sciences, Lead City University, Oyo State, Nigeria
