Follicular testosterone. Scatter plots to show the correlation of testosterone concentration (pmoles/L) (a) and total content (pmoles) (b) with follicular diameter (mm). The concentration of testosterone did not correlate with follicular diameter (3a), but total content increased with the follicular size (3b) (r = 0.52, p < 0.001).
