Not every sperm can fertilize an egg. Only a single sperm is needed to penetrate and fertilize an egg, but the journey is challenging. Thousands of sperm may never reach the egg due to various barriers within the female reproductive tract. Additionally, only a healthy, motile sperm with a strong genetic composition has the potential to succeed in fertilizing an egg.
