This study is tracking reproductive hormones in your urine to better understand what happens during a normal menstrual cycle and how it differs in people with polycystic ovary syndrome (PCOS) or athletes. Researchers will measure four key hormones and compare them to blood tests and ultrasound images to validate a new monitoring device. The goal is to create a reference guide for what healthy hormone patterns look like across different groups.
Many people have irregular or unpredictable menstrual cycles, but we don't have good tools to track what's happening with hormones at home. This study is testing whether measuring hormones in urine can help predict and confirm ovulation, which could help people with PCOS, athletes, and anyone wanting to better understand their cycle.

You would participate in one of three groups: people with regular cycles, people with PCOS, or athletes. Throughout your menstrual cycle, you would use a home urine test to measure hormones, track your menstrual bleeding and body temperature, record your sleep and vital signs, and travel to the clinic for ultrasound scans to confirm ovulation. The study also includes blood tests for comparison. You would continue this monitoring for at least one full menstrual cycle.
