Figure 4

The relationship between sperm viability and time in normal and abnormal sperm groups. In this figure, the Y-axis represents the percentage of viable sperm in all samples and the X-axis represents the time (T1 or T2) in the normal and abnormal sperm groups. The correlation between sperm viability and T1 (r = −0.888, p < 0.001, n = 15) and between sperm viability and T2 (r = −0.853, p < 0.001, n = 15) was established through Pearson correlation analysis. Using the independent sample t-test, sperm viability in the abnormal sperm group was obviously lower than the normal sperm group (t = 15.598, p < 0.001, n = 15).
