How periods develop in young girls and women
Part of Women’s health & pregnancy clinical trials.
This study looks at how the menstrual cycle matures in girls just starting their periods and in women with or without PCOS (a hormone condition). It may help doctors understand normal and abnormal cycles.
Summary written for real people, not researchers, by Clin2.
Who can take part
- For girls: Age 8 to 17.5 years, healthy weight, and early in their menstrual development.
- For women: Age 18 to 34, with or without PCOS, and regular or irregular periods.
- Mothers of participating girls can join as well.
- No medications that affect hormones (like birth control pills) for a few years.
- No chronic illnesses like diabetes, cystic fibrosis, or lupus.
- Not pregnant, and not planning to move far from the study center.

This early study looks at how certain “male-type” hormones and brain signals (measured through hormone patterns during the day and night) work in adolescent girls with high androgen levels. It may help researchers better understand causes like PCOS and related hormone timing differences.
This early-phase study tests whether spironolactone can “normalize” a key hormone timing pattern during sleep and wake cycles in mid-to-late pubertal girls who have high male-hormone levels. The goal is to learn how this medicine may affect hormone rhythms related to conditions like PCOS.
This early-stage study tests whether adding an estrogen skin patch (estradiol) can change how your body releases key reproductive hormones in adults with PCOS. It may help researchers better understand PCOS-related hormone control and signaling.
This study looks for biological markers of polycystic ovary syndrome (PCOS) in young women. If you are between 15 and 25 and have not used hormonal birth control recently, you may be able to help researchers find better ways to diagnose PCOS.
This study looks at how weight changes affect hormone levels and insulin resistance in women with PCOS. It may help understand if weight cycling is harmful or helpful.
This study looks at how diabetes might affect the menstrual cycle in teenage girls. Researchers will compare periods in girls with diabetes to those without, to see if diabetes is linked to any changes.
