What this trial studies

This observational study aims to measure variations in cerebral perfusion and other brain parameters influenced by female sex hormones and hormonal contraception. Participants will undergo MRI scans, physiological monitoring, and blood sample collection to assess brain activity, connectivity, and diffusion. The study focuses on understanding how menstrual cycles and contraceptive use impact brain function and blood flow. By analyzing these factors, researchers hope to gain insights into the physiological effects of female hormones on the brain.

Who should consider this trial

Good fit: Ideal candidates are Bachelor or Master students who have not used hormonal contraception for at least three months.

Not a fit: Patients with MRI contraindications, chronic diseases, or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how hormonal changes affect brain health and function in women.

How similar studies have performed: While studies on hormonal effects on brain function exist, this specific approach focusing on cerebral perfusion variations is relatively novel.
