The immune system may play a role in stopping a woman's biological clock. John Perry at the University of Oxford and colleagues looked at 43 genomic studies of the menopause, covering more than 50,000 women. By comparing the age that menopause began, Perry's team identified 13 regions with possible links to menopause timing. Three of the regions were housed within genes associated with the immune system. Other regions occurred within genes that control gene repair, regulate hormones and trigger inflammation.
