It is a fact, an age at first birth declined progressively for years.
Currently, the average age for a first pregnancy is 30 years, he was 24 years in 1970.
The factors that cause women to have children later and later in are numerous, and are connected with deep sociological motivations.
The number of childbirth after age 40 is about 2.5% of pregnancies.
Okay, there are few, but far from negligible, that is why we create this little page to define precisely what precautions to take and what risks are associated with late pregnancy .
What are the precautions?
You live a first pregnancy after age 35, and this is your first baby?
In fact, the medical monitoring of your pregnancy will be particularly intense.
Studies on this subject are numerous, and obstetricians are very informed about the risks and possible complications associated with late pregnancy.
This intense monitoring is done primarily in a preventive framework.
Obviously anything can take place perfectly, but the fact of considering this pregnancy as risky to deploy monitoring and appropriate management to ensure a successful outcome in the event.
This allows closer monitoring to a very reassuring finding:
It is more common to encounter accidents in young women who are not followed than in older women, who are more conservative, and are more easily motivated to accept a medical management heavier.
What are the real risks?
However, this is not to cloud the issue and explain what those risks that affect a heavier support.
At the moment of conception:
Tissue aging causes a decline in fertility after 37 years.
Oocyte production decreases by 50%, there is also the one-third drop in the number of embryos.
In addition, there is a lower rate of embryo implantation, the pregnancy rate is 19.4% before 35 and 7.1% after 42 years. (These figures are based on a conception rate by spontaneous cycle, which means that a younger woman will take about 5 or 6 months to get pregnant, and a 42 year old woman takes between 14 and 15 months.)
Finally, the probability of having gynecological pathologies also increases with the passage of time, including endometriosis and fibroids.
This is the moment of conception you may primarily have difficulties.
The second important factor is the number of miscarriages.
The miscarriage rate in the general population is 17%, it rises to 33.8% after 40, then 53% after 45 years.
