Genetic Variations May Influence Onset Of Puberty, Menopause.

reports that researchers at “Exeter and Cambridge universities showed that at least two repair mechanisms were involved” in the onset of menopause. The first repair mechanism “is used when the eggs are being formed and the woman’s DNA is being broken, rearranged and repaired,” and the second “corrects damage, caused” by environmental factors. reports that a study published in Nature Genetics found that genetic variations may “have an impact on the ages when a woman enters both puberty and menopause.” The study involved nearly 70,000 women of European ancestry and found over “50 genetic variations – including 18 previously discovered ones – that seem to be linked to the age a woman reaches menopause.” http://www.bbc.com/news/health-34380258
