Most women go through menopause between the ages of 45 and 55, but some women experience it before they turn 40.
Given that women give birth for the first time around the age of 30 on average, early menopause could be a problem for those looking to expand their families later in life.
Scientists say that in the future, a sample of saliva or blood will be enough to determine a woman’s likelihood of premature menopause.
300 variations of genes that affect a woman’s timing of menopause have been identified. For example, women who naturally lack an active gene called Chek2 enter menopause an average of 3.5 years later than women with a normally active gene.
There are already analyzes and blood tests that confirm whether a woman is going through menopause, but that could never have been predicted years in advance, only when the hormone levels began to change.
If a woman, say in her mid-twenties, knows that she is at risk of early menopause and decreased conception by the age of 30, she could react earlier and take certain steps in family planning. For example, a previous attempt to have a baby, freezing eggs, or delaying menopause by changing your lifestyle.
