The first clinical trials of the procedure, which aims to select fertile sperm, could begin next year after a research team was awarded a £120,000 grant to develop the technology by the pharmaceutical company Merck Serono.
The test identifies unhealthy sperm by tagging them with a protein dye that binds to damaged DNA. The healthy sperm can then be selected.
Some men are infertile because their sperm has genetic damage, which prevents them from fertilising eggs.
The test is comparatively cheap and would be about £100
