The figure shows a histogram of the distribution of sperm count.

The horizontal axis is labelled in 100s from 0 to 300 and has the legend "Sperm concentration (x109/L)". The vertical axis is labelled in 10s from 0 to 50 and has the legend "Number of ejaculates".

The frequencies represented are for intervals of width 20, going from 0-20 to 320-240. The frequences represented by the bars on these intervals are:
