Summary

This study looks at how sleep length and quality may affect the success of in vitro fertilization (IVF) in women. Participants will wear a ring-shaped device that tracks sleep patterns before and after a frozen embryo transfer. The goal is to see if sleep parameters like total sleep time and sleep efficiency are linked to pregnancy outcomes. Findings could help develop future treatments that improve sleep to enhance fertility.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Oura ring
What this could lead to
If a link between sleep and fertility is found, it could lead to future therapies that improve sleep to boost IVF success rates.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may not apply to all women, and the ring's sleep tracking may have limitations.
