2. Figure 1
Correlation between CAG repeat length and semen quality. Error bars for each CAG repeat length per semen parameter are given. Correlations are shown for (A) semen volume, (B) sperm concentration, (C) sperm motility, (D) sperm morphology, (E) total sperm count, and (F) total motile sperm count. The dashed line in each graph indicates the estimated regression line. R2 represents the percentage of variation of the semen parameter that can be explained by CAG repeat length variation. The P value represents the possibility of an existing correlation.
