Kind: research · Impact: medium

## In brief

- A study reports that chronic circadian desynchrony disrupts sperm development.
- The reported effect is stage-specific disruption of spermiogenesis, the final stage of sperm maturation.
- The work links this disruption to reduced male fertility.

## Why it matters

It suggests that disrupted circadian rhythms can impair sperm production and male fertility, which is relevant to research on reproductive health and biological clocks.
