Around 27,000 embryos were eligible for donation to Brazil's national stem cell research programme, according to the first annual embryo registration exercise, involving the country's 120 IVF clinics. By the first deadline (August 10), which sought to survey all embryos created until the end of 2007, some 50,000 were registered with the "national embryo production system" (SisEmbrio) by 50 clinics, said the Anvisa agency, which operates it. Anvisa thus estimates the total number of embryos to have been around 110,000. Only embryos that are unviable (genetically or morphologically defective) and supernumerary embryos stored for at least three years are eligible for research, subject to their being donated by the couple.
