Spontaneous abortion: the risk increases in the summer

The increased risk of miscarriage reports its peak during the summer season. That’s what an American study claims. The chance of a miscarriage before eight weeks of pregnancy is 44% higher at the end of August. A comparison with the end of February shows a decisive increase.

An Internet-based study analyzed couples who were not using fertility treatment.
The 12,197 participants between the ages of 21 and 45, between June 2013 and August 2020, completed the
first questionnaire of the study. Of the total, 6,104 people remained pregnant. Finally, of these the
19.5% reported a miscarriage. The pregnancy lasted only six weeks.

Here’s that one peak of spontaneous abortions was recorded in June, July and August. The risk of miscarriage
spontaneously before eight weeks of pregnancy peaked in the middle August Whatever it is
the risk is still 31% at any gestational age, but still higher at the end of August than at the end of February.

Whenever you see a seasonal variation in a result, it can give you suggestions about the causes of that result. We found that the risk of miscarriage, especially the risk of an ‘early’ miscarriage before eight weeks of pregnancy, was higher in the summer. Now we need to dig deeper to understand which types of exhibits are most popular in the summer and which of these exhibits could explain this.

It also appears that a large percentage of miscarriages are caused by too much of both
too few chromosomes Another confirmation was confirmed that the peak of the risk of abortion is higher
in South America. This is because summers are usually warmer there.
