A new skin patch designed to collect sweat has shown early promise for predicting ovulation, according to a small study reported by New Scientist. The patch measures levels of two reproductive hormones present in sweat, offering a potential alternative to more invasive or inconvenient tracking methods.
The study was small, and the results are preliminary, but the patch was able to detect hormone changes associated with ovulation. The researchers behind the work suggest that with further development, such a patch could provide a simple, continuous way for people to track their fertility.
Because the findings come from a single small study, larger trials will be needed to confirm how accurately the patch predicts ovulation in real-world conditions. Still, the approach highlights a growing interest in sweat-based diagnostics for hormonal health. No other sources were available for comparison, so these results should be interpreted as an early step rather than a definitive solution.```json {
