Hormone clues behind severe PMS symptoms under investigation
NCT ID NCT07686718
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study looks at whether women with premenstrual dysphoric disorder (PMDD) have different levels of the hormones progesterone and estrogen in the week after ovulation compared to women without PMDD. Researchers will take a single blood sample about 7 days after ovulation and measure these hormone levels. The goal is to better understand the biological basis of PMDD, which could lead to improved diagnosis or treatments in the future.
