Asthenozoospermia: Cellular and molecular contributing factors and treatment strategies.

Semen sample with poor sperm motility, which called asthenozoospermia, is considered as one of the main factors contributing to male infertility. Recognition of the cellular and molecular pathways contributing to sperm motility reduction may lead to applying novel treatment strategies for overcoming low sperm motility in asthenozoospermia individuals. In this review, we intend to discuss the main causes of sperm motility reduction in asthenozoospermia and some treatment strategies used to overcome low sperm motility.
