The truth is that menopause guilty men ?

According to experts in the segment of evolutionary genetics at the University of McMaster (Canada), the cause of menopause in older women is that male preference for younger partners.Therefore, older women just did not make sense to maintain the ability to conceive and bear children.

Copious night sweats, sudden flushing, mood swings - all these symptoms that accompany the female menopause, blame the representatives of the male sex, experts say.According to Canadian experts, the desire of men to the relations with young girls, in the end, led to the fact that in old age the ability to give birth in women disappears.That this assumption is expressed in the material placed in the journal PLOS Computational Biology.

However, contrary to the statement of British experts and, in turn, argue that the situation is vice versa.Men have to choose to continue the kind of young partners, because older women lost the ability to give birth.Scientists around the world have long been trying to solve the riddle of wh

y people, apparently, is the only species whose representatives are not able to maintain the ability to produce offspring until the end of life.



Previously, experts method has been proposed to explain this phenomenon of "grandmother effect".Thus, it was suggested that the elderly women lose their fertility at an age when they can not grow them, however, they have the opportunity to educate the children of women younger generation.From this perspective, the menopause was considered a kind of means of blocking conception of children at a certain age.

However, scientists from Canada suggests the opposite explanation for this phenomenon: it is the loss of opportunities to produce offspring cause menopausal changes in the female body.Using the capabilities of computer modeling, they concluded that in the course of evolution, mankind developed a mechanism of "preferential mating", means that a man of any age choose their partners of women younger than themselves.Consequently, this means that more elderly the fair sex have simply not been able to sense the birth of children.

According to the head of the project, an expert in the segment of evolutionary genetics professor named Ram Singh, the man who chose younger women have contributed to the loss of the older generation of women's ability to give birth.According to the scientist, human history is a huge number of examples of the fact that men of all ages preferred younger women.He also stressed that the Group of Experts, which he is co-ordinator, analyzed the development of mankind millennia ago and that the results of their research on social trends are based on the current time.

For example, a British women, on average, menopause begins at 52 years old, and the average life expectancy of women - about 82 years.Professor Singh said that having children later in life and increase life expectancy can significantly delay the development of menopause.Thus, according to the scientist, the changes in the social system will be able to delay the menopause with time, as this trend points to the fact that these women, menopause can occur later.All relevant information will be genetically transmitted to future generations, which subsequently lead to a delayed onset of menopause.
