**Health and Sperm – This Connection Still Holds Many Mysteries**

Health and sperm are undoubtedly correlated. However, even many simple questions remain unsolved today. How do sperm swim? How do they navigate? What is sperm made of? With every heartbeat, a man can produce around 1,000 sperm cells – during intercourse, more than 50 million brave swimmers are released to fertilize an egg, writes https://xrust.ru/. Only a few make it to the final destination before one sperm wins the race and penetrates the egg. Almost 350 years after the discovery of sperm, many of the questions above remain unanswered.

Using newly developed methods, however, scientists can now trace the journey of sperm – from their formation in the testes to fertilization of the egg inside the female body. The results are leading to revolutionary discoveries. Among the key findings are how sperm actually swim and what happens to them when they reach the female body. Due to the wide range of functions required from sperm cells, they need more energy than other cells. Furthermore, sperm must be flexible to respond to environmental signals and adapt to changing energy demands during ejaculation and their journey through the female reproductive tract, all the way to fertilization.

Sperm are also the only human cells capable of surviving outside the body. For this reason, they are highly specialized. However, because of their size, these tiny cells are very difficult to study, she says. While we know a lot about reproduction, there’s a vast amount we still don’t understand. The sperm cell is incredibly well-packaged. It is often described as a sack of DNA with a tail.

As scientists have begun to better understand early embryonic development, they have discovered that sperm deliver not only the father’s chromosomes but also epigenetic information – an additional layer of information that affects how and when genes should be used. This can significantly influence how an embryo develops and potentially impact the lifelong trajectory of the offspring generated by these sperm cells.
