Fig. 3From: Understanding sperm motility mechanisms and the implication of sperm surface molecules in promoting motilitySummary of the key sperm surface molecules that play an important role in regulating sperm motility. Several novel protein molecules have been found in the serum in buffalo and caprine systems; these molecules interact with their receptors, thus enhancing forward and vertical motility. These molecules can act as novel methods for treating infertilityBack to article page
