 Mice missing a sure gene are unable to supply offspring as a result of their sperm lack the connection between the tail and the pinnacle, in accordance with a examine, indicating a possible reason for male infertility.Researchers on the College of Gothenburg in Sweden have recognized a brand new protein, dubbed by them as “MC2” that performs an important half within the formation of swimmable sperm in mice.

London, Jan 18 (IANS) Mice missing a sure gene are unable to supply offspring as a result of their sperm lack the connection between the tail and the pinnacle, in accordance with a examine, indicating a possible reason for male infertility.
Researchers on the College of Gothenburg in Sweden have recognized a brand new protein, dubbed by them as “MC2” that performs an important half within the formation of swimmable sperm in mice. This protein is required to create a purposeful connection between the pinnacle and the tail of the sperm.
