Accurate Way to Predict the Age When Women Will Hit the Menopause Developed
Iran - Researchers have developed a way of accurately predicting when women will hit the menopause using a simple blood test. The average difference between the predicted age and the actual age that the women in their study reached the menopause was only a third of a year, and the maximum margin of error was between three and four years.
The project was presented at a conference in Rome on fertility and could be used outside laboratories, but if it proves effective on a wider panel. This would allow women to discover early on in their reproductive life what their expected age at menopause will be, so that they can plan when to start a family through the measurement of the rate of hormone anti-Mullerian (AMH) in the blood. In the trial, researchers at the University of Medical Sciences Shahid Beheshti have a blood test to a group of 266 women aged 20-49 years every three years to measure their hormone AMH.
Scientists have therefore established a statistical model to identify AMH levels at different ages that would predict if women were likely to have an early menopause (before the age of 45). She found that, for instance, AMH levels of 4.1 ng/ml or less predicted early menopause in 20-year-olds, AMH levels of 3.3 ng/ml predicted it in 25-year-olds, and AMH levels of 2.4 ng/ml predicted it in 30-year-olds.
In contrast, AMH levels of at least 4.5 ng/ml at the age of 20, 3.8 ngl/ml at 25 and 2.9 ng/ml at 30 all predicted an age at menopause of over 50 years old. The researchers found that the average age at menopause for the women in their study was approximately 52.
They concluded: "Our findings indicate that AMH is capable of specifying a woman's reproductive status more realistically than chronological age per se. Considering that this is a small study that has looked at women over a period of time, larger studies starting with women in their twenties and following them for several years are needed to validate the accuracy of serum AMH concentration for the prediction of menopause in young women."
