Sperm morphology is poorly understood, and because the evaluation is somewhat subjective, scores can vary on the same semen sample, in the same lab, using the same scoring techniques. If sperm morphology is abnormal, but all the other semen parameters fall within normal limits, then male fertility could still be considered normal.
