Stay close partner-in-law who tends More Fertile

Trend found in today's young couples are avoiding in-laws live near the house. The reason is that the couple could be more independent, or it could also avoid the chattering of a nagging mother-in-law. However, in-laws live near her true home offers many advantages, in addition to more efficient, it can also increase fertility.

Dr Virpi Lummaa of Sheffield University analyzed the records of the church who had lived 300 years with the last data recorded in 2000. These records contain data of birth, marriages and deaths of farmers in Finland.

The study, presented at the 2012 Euroscience conference in Dublin found that married couples who live close to the in-laws have more children. In addition, the distance between the child's birth time is also shorter. Couples also tend to marry at a young age when her mother was still alive.

Not only that, previous research has found that children born to couples who live near his grandmother's home are less likely to die in infancy. It seems that the new family benefit from the additional people who are willing to help provide care to children.

Dr Lummaa not find any differences between the laws of the mother or father. However, previous research on African families find that the mother-in-law of the mother is a person who gives the greatest benefit.

The positive impact of the mother-in-law of the mother is probably due to age. Men generally married at an older age than women, the paternal grandmother are also typically older and less able to help care for grandchildren.

"The role of grandparents is less obvious impact is not because the grandfather was not doing anything, but because of the lack of help from grandparents parenting grandchildren can be translated directly," said Dr. Lumma as reported by Medical Daily, Tuesday (07/17/2012).

In addition to studying the effects of close-in-law, Dr. Lummaa also learn why women lose the ability to have children when they were relatively young, but other mammals are able to reproduce into old age.

The latest research confirms the findings support the theory that menopause is a natural way to keep the women did not have more children when she was young counted as a grandmother. This mechanism will make menopausal women more focused care for her grandchildren at the same time avoid the trauma of childbirth.
