Women should have the chance to freeze their eggs or ovarian tissue in their 20s or early 30s to avoid having fertility problems if they want to conceive later in life, experts say. More and more women are delaying having a family, perhaps because they have not found the right partner or because of their career. A woman’s fertility declines steeply from around the age of 35, which means that many women in their late 30s and early 40s are attempting IVF, often without success, says a study in the Lancet medical journal.
