In order to reach the egg for fertilization, sperm have to survive a long and arduous journey through cervical mucus and the cervix, and then up into the fallopian tubes. Considering that the size of a sperm is roughly 0.002 inches long (not visible to the naked eye), this would be about the same as going from Hawaii to Los Angeles - or at least it feels that way to the sperm! The fastest of the sperm will take about 45 minutes and the slowest need around 12 hours to reach the egg. Most sperm never make it. They either run out of energy, go in the wrong direction, or chase their tails in circles. Some sperm will have been killed off by natural antibodies or hostile cervical fluids. In the end, it’s just a few, fine-figured sperm that find their way to the egg and hope to become the lucky one. MotilityBoost offers many of the most well-known ingredients for supporting male fertility and sperm motility, including L-Carnitine, L-Arginine, CoQ10, Vitamin B12, and Quercetin.
