Technology helps preserve fertility of boys with cancer
Researchers have found a promising way to preserve sperm stem cells so boys can undergo cancer treatment without risking their fertility.
Adult men can have their sperm frozen before undergoing radiation or chemotherapy, both of which can render sperm infertile. But boys who haven’t been through puberty can only have sperm stem cells removed and frozen in anticipation of technology that could culture the cells and place them back in the testes, where they produce sperm after puberty.
