To treat male infertility, scientists suggest to take stem cells harvested from a man's skin and make them a sperm, showed the animal research.

This approach to treating azoospermia -- a genetically linked inability to produce viable sperm -- is still in the initial stages, the study authors cautioned. And success with animals does not always translate into potential human treatments, the Newsmax Health reported.

However, the research team said that when stem cells were harvested from three azoospermia patients and then injected into the reproductive system of healthy mice, the cells began morphing into the kind of precursor cells that usually become healthy sperm.

"We were able to take stem cells drawn from the skin of infertile men -- cells that can make any type of cell in the body -- and inject them right into the testes of mice where the sperm is usually formed. And we found that these cells very efficiently . . . made immature sperm cells." said study senior author Renee Reijo Pera, a professor of cell biology and neurosciences at Montana State University
