2. Figure 1
Correlation between current monthly PM 2.5 levels and current sperm parameters. The black lines represent the PM 2.5 values. Notice the increased levels of PM 2.5 during winter. (A) Correlation between PM 2.5 and sperm morphology. There is a reduction in sperm morphology that chronologically correlates with the increase in PM 2.5 values (r = –0.076; P=0.018). (B) Correlation between PM 2.5 and sperm motility. There is a delayed reduction in sperm motility in the 2 months that follow the increase in PM 2.5 values, (r = –0.330; P=0.009). (C) Correaltion between PM 2.5 and sperm concentration. There is no correlation between sperm concentration and PM 2.5 values.
