Sons Born to Overweight Mothers’ More Likely to be Infertile
In the Danish study of 9,232 adult sons and daughters, 9.4% of participants were infertile.
The authors found that:
- Sons whose mothers had a body mass index over 25 kg/m2 before pregnancy had 1.4-times higher odds of infertility.
- 12.5% of couples are affected by infertility.
- One-third of couples’ infertility cases are caused by male reproductive issues, one-third by female reproductive problems, and one-third is either a combination or due to unknown factors.
“Infertility is a global public health issue, and it is important that research focus on addressing risk factors,” said lead author Linn Arendt, MD, PhD, a postdoc at Aarhus University and Aarhus University Hospital.
The study findings add to evidence that weight during pregnancy may also affect male future reproductive health.
