Having sons may make a mother's age faster, according to a study.

The claim that having sons may make a mother's age faster is supported by some studies indicating a potential link between having sons and accelerated biological aging due to stress and caregiving demands. However, the effect is described as small and not solely attributable to having sons. The evidence suggests that the impact of having sons on aging is complex and multifaceted, with other factors such as the number and timing of children also playing significant roles. Therefore, while there is some support for the claim, it is not definitive and should be considered with caution.
