COMPARATIVE STUDY OF SPERM VITALITY IN FERTILE AND INFERTILE MALES

AIM: To study sperm vitality in fertile and infertile males, analyze and correlate. MATERIALS AND METHODS: Total 100 semen samples were studied in each of the experimental and control groups. Sperm vitality was determined by the dye- exclusion test. RESULTS: The percentage of vital spermatozoa in the control group was more than 74% in all the cases which was within the normal limits. However only 65 cases out of the total 100 in experimental group, showed the vitality percentage within normal limits (>74%). In 35 samples of the experimental group, the vitality percentage was in the range of 60 to 73%. The mean vitality percentage of the experimental group was 82 ±6.78 and that for the control group was 84.45. The difference in the mean and median values of vitality in the two groups was statistically significant. CONCLUSION: Sperm vitality was highly significantly more in semen samples of fertile males than those of infertile males. KEYTERMS: Infertility Male, Semen Analysis, Fertility, Pregnancy.
