Impact of simulated microgravity on female pelvic blood flow

Female Pelvic Blood Flow Under Simulated Microgravity

Not applicable Interventional Koc University Hospital · NCT06633692

This study tests how lying in a head-down position, which simulates being in space, affects blood flow to the reproductive organs in healthy women aged 18 to 44.

What this trial studies

This study investigates how simulated microgravity affects blood flow to female reproductive organs using Doppler velocimetry. By placing participants in a head-down tilt position, researchers aim to replicate the physiological changes experienced during spaceflight. The study focuses on understanding the redistribution of blood circulation and vascular dynamics in healthy women aged 18-44. This research is crucial as space missions become more frequent, highlighting the need for insights into women's health in microgravity environments.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy females aged 18-44 without a history of reproductive tract pathologies or cardiovascular diseases.

Not a fit: Patients who have undergone hysterectomy or oophorectomy, are pregnant, or have premature ovarian insufficiency will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of female reproductive health in space, potentially leading to improved health outcomes for women during long-duration space missions.

How similar studies have performed: While there is limited information on pelvic blood flow under microgravity, similar studies on cardiovascular responses to microgravity have shown significant physiological changes, indicating potential for success in this novel approach.
