A skin patch that collects sweat may be used to predict ovulation.

What it means

New Scientist reports on a wearable skin patch that collects sweat and measures the hormones oestrogen and progesterone, with the goal of predicting ovulation. The patch offers a non-invasive, continuous alternative to current methods like urine test strips or fertility monitors, and could provide individuals with real-time insights into their reproductive cycle.

Accuracy & sourcesGrounded

New Scientist is a reputable secondary source, and the article appears to be reporting on a specific study or prototype (likely from a research group). While the underlying claim is scientifically plausible—hormone levels in sweat correlate with blood levels—the patch is likely still in development or early testing, so claims of practical ovulation prediction should be treated as preliminary.
