Male infertility is often the cause of sterility in a couple. In these circumstances, it may be due to poor sperm maturation. There is now a chance to overcome this defect, using a technique called round spermatid injection or ROSI. The outcomes of its use have now been described following the birth of 14 children from 12 pregnancies, using 734 oocytes that were previously activated by an electric current (PNAS 112; 14629-14634, 2015). While this is a promising new step to resolve male infertility, its ethical assessment will have to framed within the difficulties presented by assisted procreation techniques. (See HERE)
