About

Sacred Womb

Features
Read full description

The SACRED WOMB study aims to understand how daily experiences of stress might influence the risk of progression, regression, or stability of high-grade cervical lesions through potential changes in the vaginal microbiome and cortisol levels. WHO CAN JOIN? Eligible participants are women diagnosed with high-grade cervical lesions who are willing to provide daily feedback and biological samples over a specified period. While there may not be direct benefits to you, your participation will contribute valuable information that can help improve understanding of cervical health and potentially lead to better prevention and treatment strategies. Contact us with any questions to see if you are eligible to participate. Visit us at: www.sacredwombstudy.com
