Climate Change Will Affect Babies’ Gender Distribution


Climate change, one of our planet’s most worrisome yet neglected problems, will affect the sex distribution of newborns, scientists say. Scientists, who also include natural selection in their explanations, say that in this context, more boys will be seen in warm areas.

which already has many irreversible effects climate change, according to the statements of scientists, newborn babies your gender will also affect. The research, which was carried out according to data from many different places, also reveals how the genes of boys and girls are affected by the environment.

in japan carried out in question in research scientists, especially boys, external factors that cause stress against claimed to be more vulnerable. Scientists examining the earthquakes in Japan and the birth data of those years supported this with the data they obtained.

Babies born 9 months after the earthquakes saw a 6 to 14 percent decrease in the rate of baby boys from the previous year:


Scientists, who included more than one earthquake in the research, found that babies born at the end of 9 months following these earthquakes compared to the previous year. that the proportion of men experienced a decrease of between 6 and 14 percent told.

Although scientists do not yet know why the sex ratio is so affected, the lead author of the study Dr. Thought of Fukudafound in men The fact that the Y gene is more vulnerable to stress He said it might have something to do with the issue.

Do more girls die than boys?


He said that the sex ratio was equal at first, but changed greatly during pregnancy. Steven Orzack, made in research states that they have seen that more girls die during pregnancy than boys.

from the University of California Ray Catalano draws attention to natural selection. Catalano, who stated that the mother was biologically and constantly defended against some sperms, but allowed some of them to pass, said at this point. chromosomal and genetic features play a decisive role. states.


around the world every 103 to 106 boys were born per 100 newborn girls. said Catalano wherever they have data. baby boys prenatal to die states that they are more prone. In addition, although the reason is not clear, male infants biologically she says she is weaker and less vulnerable to disease and prenatal death.

Colder years mean fewer boys:


Information covering the years between 1878 and 1914, presented by Catalano by examining the northern countries, fewer boys as a result of cold years, but these seen more durable than others revealed that. It was also seen that these children who grew up from here gave birth to more children than expected. This supports Catalano’s idea of ‚Äč‚Äčnatural selection.

Stating that a new and rapid adaptation process will come with global warming, Catalano said that such situations less predictable says it will. Again, with global warming, earphones Stating that such problems will contribute to stress, Catalano finally concludes his statements by saying that as the climate changes, the characteristics of the population will also change.

Warmer years mean more boys:


from Turku University Samuli Helle, in the study he carried out, every 1 degree Celsius in the positive direction, the newborn baby don’t be a man 0.06 percent chance with a ratio like that you raised revealed. This means that an annual increase of 3 degrees will cause 0.18 percent more male babies to be seen.

This ratio may seem small to you. It already is. But Helle is quite crowded places annually when we consider a few thousand extra boys It says it can be seen.


Common Disorders During Pregnancy and Their Causes

While scientists are discussing whether the said effects are permanent, it is said that these effects will not affect the whole world. This issue, which we can say that we are progressing with theories that sound quite logical at the moment, will be resolved in time.
