UK scientists created human sperm from stem cells for the first time in a bid to better understand the causes of male infertility. The researchers from England’s Newcastle University developed a technique to turn stem cells with male chromosomes from human embryos into reproductive cells, known as germline, and prompt them to divide. The divided cells produced functional sperm, the scientists said. The new technique will not only come out to be a boon to understand male infertility but also to help develop new ways for couples suffering infertility so they can have a child which is genetically their own.
