A new study published in the journal PNAS shows that some sperm cannot swim straight because they lack a protein called VSP. This motility defect seriously impacts the rates of successful fertilization. In addition, VSP is also found to regulate the amount of calcium that enters the flagellum, the whiplike organelle that propels the sperm towards the waiting ovum or egg. This important discovery may help treat infertility more effectively.
