Washington: Researchers have found out in a study in Japan that climate change may be held responsible for altering the ratio of human males to females thar are born in some countries.
Nearly 90,000 newborns and about 1,000 fetal deaths per month in Japan was recorded in the study done in recent years by M and K Health Institute in Ako.
Scientists found out that the ratio of male to female babies born in the country had been decreasing. There had been fewer male babies born relative to the number of female babies born as reported by Live Science.
The researchers considered fetal deaths to be those that were spontaneously aborted (or miscarried) after 12 weeks of pregnancy.
However, the new study only found an association, and could not prove that the climate changes were responsible for the change in sex ratio in Japan. Other factors, such as pollution and toxins in the environment, may affect sex ratios.
The study came out in an issue of the journal Fertility and Sterility.
