The figure is in two parts: a histogram of the distribution of log sperm concentration and a normal plot of this distibution.
The histogram shows a negative skew distribution.
The normal plot has "Inverse Normal" on the horizontal axis and log sperm count on the vertical axis. The plot shows a curve, becoming progressively less steep from left to right.
