Sons born to mothers who are overweight were more likely to be diagnosed with infertility, stated a recent study published in Acta Obstetricia et Gynecologica Scandinavica.
There was no association between maternal weight and infertility observed in daughters.
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.
The study findings add to evidence that weight during pregnancy may also affect male future reproductive health.
