Sperm motility disorder (asthenozoospermia) is a condition characterized by a reduction or complete loss of the sperm's progressive movement ability. This condition often results from morphological or structural defects in the sperm. Defects in the tail structure, which is primarily responsible for sperm movement, significantly impair motility. Furthermore, structural anomalies in the midpiece of the sperm, where energy-producing mitochondria are located, can also lead to motility disorders. According to World Health Organization (WHO) criteria, the percentage of progressively motile sperm in a normal semen analysis should be 32% or higher.
