Very Early Estrogen and Ovulation Registry
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This registry study is for people who have stopped getting periods due to a condition called functional hypothalamic amenorrhea, which may be linked to low estrogen and ovulation problems. Researchers want to track hormone patterns over time to better understand how the condition develops.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have not had a period for 3 or more months in a row.
- A doctor has diagnosed you with functional hypothalamic amenorrhea, or your lab tests match that condition.

- You should not have other conditions that explain your missed periods, like PCOS or early menopause.
- You are premenopausal and not pregnant or breastfeeding within the last 6-12 months.
