Evaluation of sperm motility includes:
A) Determining the appearance of the tail piece
B) Differentiation between forward and lateral movement
C) Two evaluations performed 3 hours apart
D) Two evaluations performed 3 days apart

Question

Quizplus · Accepted Answer

Differentiation between forward and lateral movement is a crucial component in evaluating sperm motility, as it allows for determination of the percentage of sperm that are actively motile, as well as identification of any abnormalities or deficiencies in forward progression. Determining the appearance of the tail piece is not a reliable indicator of motility, and performing evaluations too far apart (such as 3 days) can yield inconsistent results due to factors such as sample deterioration or variation in collection methods. Performing evaluations too close together (such as 3 hours) may not allow enough time for changes in motility to occur.
