Reaching a long-sought milestone, Japanese researchers have demonstrated in mice that eggs and sperm can be grown from stem cells and combined to produce healthy offspring, pointing to new treatments for infertility. If the achievement can be repeated in humans — and experts said they are optimistic that such efforts will ultimately succeed — the technique could make it easier for women in their 30s or 40s to become mothers. It could also help men and women whose reproductive organs have been damaged by cancer treatments or other causes.
