A comparative study of the hematological values in the ovulation and luteal phases of the menstrual cycle

Abstract

This study compares the hematological values of the ovulation phase with the luteal phase of the menstrual cycle. Sixty subjects with 30 subjects each in the ovulation and luteal phases of the menstrual cycle were studied. Ethical clearance and informed consent were obtained for the study. Hematological parameters of blood samples collected using aseptic technique were analysed using the Swelab Alfa automatic hematology analyser. Granulocyte(x103/ìL) value for the ovulation and luteal phases were 1.48±0.15 and 2.53 ±0.36 respectively (p<0.05). The Granulocyte% for the ovulation and luteal phases were 33.34±2.46 and 45.81±2.93 respectively (p<0.05). The Lymphocyte % for ovulation and luteal phases were 58.89±1.66 and 47.58±2.76 respectively (p<0.05). The Mean platelet volume values for ovulation and luteal phases were 7.68±0.30 and 8.06±0.31 respectively (p<0.001). The plateletcrit for ovulation and luteal phases were 0.14±0.02 and 0.15±0.02 respectively (p<0.001). The Platelet Width Density for ovulation  and luteal phases were 11.53±0.49 and 12.13±0.48 respectively (p< 0.01). The Platelet Larger Cell Ratio for ovulation and luteal phases were 15.46±1.82 and 18.04±1.78 respectively (p< 0.01). Red cell parameters remained unchanged in both phases of the menstrual cycle. Platelet and granulocyte parameters are the  hematological changes observed in the ovulation phase when compared to the luteal phase.
