The breakthrough could help thousands of infertile men and young boys left sterile from cancer treatment all over the world, the scientists say
Scientists have claimed to have grown mature human sperm in test tubes in a breakthrough that could help combat male infertility.
The sperm cells, which have been developed for the first time in a “bioreactor” in a laboratory, are said to look identical to those produced naturally.
And according to the scientists at a research institute in Lyon, France, the technology could be ready within up to four years to help men who are unable to make their own sperm have their own biological children.
However, sceptics have expressed doubts, claiming the findings should not be verified until the research is published in a peer-reviewed journal.
