Sperm in the race: New study has an impact on pregnancy!

An exciting chapter in research on fertility has now been revealed at the Med Uni Graz! As reports krone.at , a new study has shown that sperm not only plays a role in fertilization, but also penetrate the embryo and influence its development. This groundbreaking discovery could have far -reaching effects on the success of pregnancies. Scientists under the direction of Berthold Huppertz explain that the path of the embryo to the uterus is decisive and that it is accompanied by many sperm on this way. Some of these sperm could even disturb the implantation of the embryo, which could lead to difficulty in successful pregnancy.

But that's not all! family.de adds that the process of fertilization itself is a hard race. Of the approximately 100 to 150 million sperm that are released during an ejaculate, very few make it close to the egg cell, the acid milieu of the vagina kills a large part of the sperm. The way to the egg cell during the ovulation is crucial. Only the best sperm that match the right time and are ready for fertilization can be successful. In this exciting phase, the choice of sperm is guided by special chemical signals that are sent out by the egg cell.

The multi -layered role of sperm

The theory is particularly exciting that a competition between the sperm seems to be preferred by various men, who are intimate with a woman at the same time. This dynamic could not only influence the success of pregnancy, but also genetic properties that are passed on to the child - an explanation that can also be observed in the wildlife. In addition, the researchers formulate the hypothesis that frequent sexual contacts could possibly reduce the likelihood of pregnancy, since excess sperm can make it difficult to implant the embryo.

summarized, a complex image of human reproduction results from these findings. The path from the sperm to fertilized egg cell and finally to implant the embryo is full of challenges and surprises. This new perspective could lead to further research necessary to understand the forces of these tiny creatures that lay the foundation for new life even better.
