    DescriptionEnglish translation:

    You would say the faster a sperm moves, the better. Then he has the best chance of being the first to arrive. New research shows that this is not entirely correct. Sperm swim much better if the tip of their tail doesn't move.

    Researchers found this out when they examined in a mathematical model what had an effect on the movement of the sperm cell. They saw again and again that the movement of the tail was much more efficient (up to 4 times more) if the last bit did not move. In fact, sperm with a lazy tail tip swam 70 percent faster. This is an important find, because knowing what characterizes a good swimmer is important knowledge for fertility research.

    In this audio you will hear researcher Meurig Gallagher from the University of Birmingham . Read more about the study here: Doing more with less: Sperm without a fully active tail move faster and more efficiently, new UK study finds .

    Of course, many more factors determine whether a fertilization is successful or not. The woman's egg also plays an important role in this. Earlier research has shown that the egg even influences which seed may even come close: Egg cells prefer some sperm cells over others .
