In a Weird Twist, Sperm Have Been Caught Poisoning Other Sperm to Get Ahead in Mice

In a Weird Twist, Sperm Have Been Caught Poisoning Other Sperm to Get Ahead in Mice
5 FEBRUARY 2021
When sperm race, it s for keeps. So it comes as little surprise that in some species, the competition over who reaches the egg first can get a little dirty.
A variant in mice genes has been found to give sperm that possess it a clear advantage by poisoning its peers while they re still in development, robbing them of their ability to efficiently sniff their way towards the egg.

In a rather karmic twist, a race consisting only of would-be assassins would be a complete disaster, with researchers finding the genetic variant risks overdosing on its own killer cocktail unless the race is balanced out by its victims. ....

Sperm 'switch' would allow men to turn their fertility on and off

Study Finds
Sperm ‘switch’ would allow men to turn their fertility on and off
BERLIN, Germany The biological race between sperm to reach an egg is a fierce and competitive process. Now, researchers in Germany say they have discovered which protein gives sperm the winning edge. Their study finds a molecular “switch” in sperm could also allow men to turn their fertility on and off.
Experiments on mice find the “winner” carries a set of toxic mutations that poison rival sperm. Researchers say a genetic factor called “t-haplotype” promotes the success of the sperm carrying it. They are also fueled by a protein called RAC1, the molecular switch that propels sperm forward. ....
