Biotech researchers aim to expand reproductive opportunity and equity

New technologies could enable women who have lost their fertility to age or illness to conceive with their own eggs — and to do so with far less suffering than in vitro fertilization (IVF) currently exacts. Or enable men with infertility problems to generate healthy sperm from other kinds of cells. Or even same-sex couples to create sperm from biological females or eggs from biological males and conceive children who are genetically related to both parents.
