The NORMA Study

WHC AdminParticipate in Research

We are recruiting, naturally cycling females to participate in a study that involves tracking the MC through

  1. calendar counting,
  2. urinary ovulation identification, and
  3. salivary measure of hormones towards the end of the MC.

The study duration for each participant in this study is 3 to 4 months. Participants will be asked to complete baseline and monthly surveys, daily app use, up to 10 days of urinary ovulation, and one day of salivary hormones. The typical time commitment is approximately 10-minutes/day.
