Scientists have claimed they have found a way for women to have babies without men by creating artificial sperm. The team from China claim they have created healthy mouse babies by injecting laboratory-made sperm into eggs to produce mouse offspring. The scientists claim their stem cell technique could pave the way for new treatments for male fertility.
But British experts have called for the results to be independently verified and pointed out that any practical application is likely to be a long way off. The mouse cells produced were technically “spermatids” – undeveloped sperm that lack tails and cannot swim. Yet when they were injected into mouse eggs, mimicking a common IVF technique called Icsi (intracytoplasmic sperm injection), they delivered viable embryos and healthy, fertile babies. READ MORE
