Summary

Story summary

A Psychoneuroendocrinology study finds partnered men with school-aged children have lower testosterone than single men or partnered men without children.
The reduction persists beyond infancy and does not raise risk of clinically low testosterone.
The study analyzes data from 4,903 men aged 20–60, using serum samples to measure testosterone.
Limitations include a single blood sample and cross-sectional design, preventing causation; future research should examine parenting behaviors' impact on hormonal changes.
