View Original AbstractSwiss study found no effect of shortwave radiation on baby gender ratios, contradicting earlier Danish research and highlighting inconsistent EMF pregnancy findings.
Plain English Summary
Swiss researchers studied whether shortwave radiation exposure during pregnancy affects the gender ratio of babies born to female physiotherapists, following up on a Danish study that found fewer male births. They surveyed 2,846 Swiss physiotherapists about their radiation exposure and children's gender, analyzing 1,781 pregnancies. The study found no difference in gender ratios between exposed and unexposed mothers, contradicting the earlier Danish findings.
Study Details
The goal of this study was to investigate whether the deficit of male births found among the offspring of Danish physiotherapists exposed to shortwave radiation during the first month of their pregnancy could be confirmed among the offspring of physiotherapists from Switzerland.
A self-administrated questionnaire was mailed (two mailings) to all of the 2846 female members of th...
The gender ratio (the number of males per number of females x 100) was 107 with a 95% confidence int...
No atypical gender ratio was found for the children of female physiotherapists from Switzerland who had been exposed to shortwave radiation at the beginning of pregnancy. The findings of the Danish study could not be confirmed.
