Expression of Target in Endometriotic Lesions

July 8, 2026 updated by: Lei Zhang, Beijing Tsinghua Chang Gung Hospital

To Investigate the Expression of Target in Endometriotic Lesions

Endometriosis is a common gynecological disorder associated with chronic pelvic pain and infertility, which affects women of reproductive age worldwide. This study aims to investigate the expression patterns of specific molecules in tissue specimens obtained from patients with endometriosis. The investigators will compare the expression levels of these molecules between endometriotic lesions and normal tissue. The primary objective of this study is to elucidate the potential roles of these molecules in the pathogenesis of endometriosis.
