whatshappeningtothekids: Evidence suggests women’s ovaries can grow new eggs Scientists have uncovered the first evidence that the human ovary may be able to grow new eggs in adulthood.If confirmed, the discovery would overturn the accepted view that women are born with a fixed number of eggs and that the body has no capacity to increase this supply. Until now this has been the main constraint on the female reproductive lifespan. The findings, if replicated, would raise the prospect of new treatments to allow older women to conceive and for infertility problems in younger women. The small study, involving cancer patients, showed that ovarian biopsies taken from young women who had been given a chemotherapy drug had a far higher density of eggs than healthy women of the same age.Prof Evelyn Telfer, who led the work at the University of Edinburgh, said: “This was something remarkable and completely unexpected for us. The tissue appeared to have formed new eggs. The dogma is that the human ovary has a fixed population of eggs and that no new eggs form throughout life.” Ovarian biopsies taken from young women who had been given a particular chemotherapy drug showed that the tissue appeared to have formed new eggs.
