Menopause mother-in-law occurs with the arrival in the house of the bride

Scholars argue that competition between women of a certain age and their daughters-in-law plays a role in the occurrence of menopauses.

In principle, menopause is an evolutionary mystery. Research is still unable to draw a clear picture of why women lose the ability to reproduce at the age of about 50 years. In this regard, in Finland, studies have been conducted, which were supposed to find the reason why women lose the ability to reproduce at about the same time, when their children start a family.


Scientists have suggested that people may have been partly to develop this strategy in order to reduce competition between generations of fertile women in one family and to increase child survival during periods when resources for the education of children is not enough (this includes food, time and care services to children between generations living under one roof). Perhaps this is a key factor in the evolution of menopause, which is called the hypothesis of reproductive conflict.




The researchers found that children born to an elderly woman, who was pregnant at the same time as her daughter-in-law, had 50 percent less likely to survive up to 15 years. Meanwhile, children born to young women who are pregnant at the same time as the mother-in-law, had a 66 per cent less likely to survive to adolescence. However, the simultaneous pregnancy mothers-in-law and daughters-in-law does not have a significant impact on child survival.
