There are many new methods against male infertility. Finally, it seems that crocodile sperm may be useful. That's right: Australian scientists conducted a study on marine crocodiles in which they were able to identify a group of proteins that give sperm the ability to move and recognize eggs, and which are very similar to those found in humans.
Obviously, the factors that cause infertility can be different, and therefore the solutions must be different. But the results of the research conducted by the University of Newcastle (UK) and published in the journal Proceedings of the Royal Society B, they look really positive. «We hope - said Brett Nixon, coordinator of the study - to use the crocodile as model to understand the functions of sperm at a basic level and see if we can apply this discovery in treatment of sterility in ours species".
For the test was collected and used the sperm of various crocodile specimens. The "defects" that lead the sperm not to fertilize the egg are linked to its shape (unsuitable for centering the egg) or vitality. Studying how does it work crocodile sperm will soon be understood how the human sperm works, in cases of infertility problems.
