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.
- Your hormone levels must fall within certain ranges (like low estradiol and normal thyroid/prolactin).
- 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.
- You are able to read English and give consent.

This study looks at how body fat and exercise relate to how your ovaries work and how your hormones function. It may help explain why some women have irregular ovulation or hormone problems, and how lifestyle factors affect them.
This trial tests whether health and lifestyle support can help women restore their periods by addressing the root causes of functional hypothalamic amenorrhea (a condition where stress, low energy, or excessive exercise stops ovulation). The goal is to improve hormone function and overall well-being.
This trial tests if kisspeptin injections can help women with hypothalamic amenorrhea (a pause in periods due to stress, low weight, or too much exercise). The goal is to see if it can restart the reproductive system naturally.
This study looks at how eating habits and activity levels affect menstrual health in women ages 16-30 who exercise at least twice a week. It aims to see if nutrition knowledge and behaviors relate to menstrual function.
This study collects health information from women going through perimenopause (transition to menopause), menopause, early menopause, or premature ovarian insufficiency (POI—early loss of ovarian function). Researchers use this data to better understand these conditions and improve care.
This study looks at how the environment and your body's natural hormones interact. It is for people with reproductive or hormone-related conditions such as low sex hormones (hypogonadism), infertility, early or late puberty, PCOS, or menopause. The researchers will observe participants over time to learn more about these conditions.
