Late births
In general, late births are women who, at the time of birth , clearly exceed the classic gestational and childbearing age between 18 and 30 years.
The phenomenon of late births has intensified significantly in the recent past, as more and more women, especially academics , are postponing the time of family planning through many years of training and study , as they have to worry beforehand about the break in pregnancy , birth and child-rearing in the career planning advised to falling behind and having to accept large professional disadvantages in buying if not to fall into social isolation even if in addition their partnership fails. It is not uncommon for family planning to be given up entirely.
Biologically, the age of childbirth has tended to shift forward , due to the earlier onset of biological fertility due to an earlier onset of puberty and the associated sexual maturity (in 1994 the average age was 12.2 years).
Another aspect is the statistical accumulation of some genetically caused disabilities in the child, such as forms of trisomy or Marfan's syndrome , which occur more than average in children of late-giving women. One reason for this is that the woman's egg cells , in contrast to the man's sperm set , are not always newly formed, but are created in the ovary at the time of their own conception and embryonic development and remain unchanged until their own death, regardless of whether they are gives birth or not.
