... the SpermComet test, developed by leading fertility doctor Professor Sheena Lewis, checks for tiny tears and breaks in sperm’s DNA.Sperm with damage to their genetic material are less likely to make a woman pregnant and if a woman does conceive, she is more likely to miscarry.
The test uses chemicals to ‘relax’ the tightly coiled strands of DNA in each individual sperm and then uses an electric field to separate them out.
Intact DNA bunches together and shines brightly, like the head of a comet, while broken material fans out and gives off a weaker glow.
By looking at the length of the tail of damaged DNA, the scientists can tell how badly affected a man’s sperm is.
