Figure 2: Nomogram for predicting the probability of good freezability ejaculates. Locate semen values on each axis, and compare these with the "Point" axis to determine how many points are attributed to each variable. Then, locate the sum of the points for all variables on the "Total Points" line to determine the possibility of good freezability ejaculates on the "FR" line. PR (%): progressive motility; VSL (μm s^{−1}): straightline velocity; VAP (μm s^{−1}): average path velocity; FR: freezability rate. −1): straightline velocity; VAP (μm s^{−1}): average path velocity; FR: freezability rate.">
