Professor Pacey said: “When we decoded the results, I nearly fell off my chair.
“We didn’t really expect that at the end of the study there would be any difference in the sperm from men who took the LactoLycopene versus those who took the placebo. “The improvement of sperm morphology – the size and shape of the sperm – was dramatic. We used a computer system to make these measurements, which takes a lot of the human error out of the results.
“This was the first properly designed and controlled study of the effect of LactoLycopene on semen quality, and it has spurred us to want to do more work with this molecule.”
