Scientists in Spain had created human sperm from skin cells, a medical feat which could eventually lead to a treatment for infertility. The researchers said they were working to find a solution for the roughly 15 percent of couples worldwide who are unable to have children and whose only option is to use donated sperm or eggs. The researchers managed to reprogram mature skin cells by introducing a cocktail of genes needed to create gametes and within a month the skin cell was transformed to become a germ cell, which can develop into sperm or an egg. http://phys.org/news/2016-04-scientists-skin-cells-human-sperm.html
