How sex hormones affect brain blood flow
Treatments studied
Part of Brain & nervous system, Heart & circulation, Hormones & metabolism clinical trials.
This study looks at how the hormones estrogen and testosterone affect blood flow in the brain and how your body manages energy. You may be a good fit if you are a healthy young adult (18–40) who does not smoke, has no chronic diseases, and — if you are a woman — has regular periods and is not on hormonal birth control.
Summary written for real people, not researchers, by Clin2.

This study looks at how blood flow in the brain differs between people with and without metabolic syndrome, and whether it varies by sex. You may be eligible if you are a healthy young adult or have metabolic syndrome.
This study looks at how blood vessels in the brain change as women age. It may help understand why some women have higher risk for certain health problems later in life.
This study examines how estradiol and progesterone (two female hormones) influence hunger, appetite, and how your body uses energy. Understanding this connection may help explain why appetite and energy levels change throughout the menstrual cycle.
This study checks how female hormones may change blood flow in the brain. You may be asked to undergo an MRI scan while hormone levels are assessed.
This study looks at how the nervous system controls blood pressure differently in men and women. It involves a single visit where you'll receive a small dose of medications through an IV and have your nerve activity and blood pressure measured.
This study looks at how hormone treatments (estrogen, progesterone, or testosterone) may affect how blood vessels tighten in the body, including in the kidneys. Researchers measure these effects to understand potential impacts on blood flow and blood vessel control.
