Scientists Identified 12 DNA Areas Responsible for the Age at which We Have the First Child
Researchers from the University of Oxford in cooperation with the Universities of Groningen, The Netherlands, and Uppsala, Sweden, have pinpointed 12 DNA areas that are associated with the age at which people usually have their first child and the total number of children during the life course.
For their study, the scientists analyzed 62 databases that included information from 238,064 men and women for age at first birth, and almost 330,000 men and women for the number of children.
Previously, it was believed that the age at which we have the first child is connected to personal choices and social circumstances. But now this new research proves that genetic variations are responsible for this age.
Lead author Professor Melinda Mills, from the Department of Sociology and Nuffield College at the University of Oxford, says: “For the first time, we now know where to find the DNA areas linked to reproductive behaviour. For example, we found that women with DNA variants for postponing parenthood also have bits of DNA code associated with later onset of menstruation and later menopause.”
