 Menstrual cycle is a physiological process that occurs in women. Changes in the levels of female sex hormones during menstrual cycle are

identified to affect the coagulation cascade by producing similar changes in the prothrombotic tendency and the fibrinolytic activity of healthy
women. Aim of the study: The estimation of total platelet count (PC), platelet percentage (PCT) and mean platelet volume (MPV), in different
phases of menstrual cycle. Materials and Methods: The study was conducted on 30 female subjects in the age group of 13 to 45 years. Three venous
samples were taken during single menstrual cycle in menstrual, proliferative, and secretory phases in each subject and were followed up. Results:
Comparison of mean PC (Table 1), PCT (Table 2) and MPV (Table 3) between three phases of menstrual cycle showed statistically significant
difference (p<0.0001). Platelet count was significantly lower in menstrual phase compared to proliferative phase which shows higher level relative
to secretory phase.
