Oxidative Stress Gene Polymorphism and Ovarian Reserve Functione

• Conditions: Recruitment
• Interventions: Genetic: endometriosis

• Registration Number: NCT03682341
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

the relationship between FOXO3A-bim pathway gene polymorphisms and ovarian reserve function of paitients with ovarian endometrioma

Detailed Description

Ovarian reserve refers to the left ovarian cortex follicle growth, development, the quantity and quality of potential ability of oocytes, reflects the fertility in women. Ovarian endometrioms have an effect on ovarian reserve function. Oxidative stress is one of the important reasons. The effect has individual differences and the mechanisms are not clear.FOXO3A-bim pathway gene polymorphisms have been reported to related to individual variation of ovarian reserve function of paitients with POF. Our working hypothesis is that FOXO3A-bim pathway gene polymorphisms are also related to ovarian reserve function of paitients with ovarian endometrioma. In recent 10 years, we have set up a database including more than 2000 cases of ovarian endometrioma. In this project, we are going to investigate the oxidative stress factors, the level of sexual hormone, ultrasound information and the relationship between FOXO3A-bim pathway gene polymorphism.All these multi-diciplinary research will lead to novel understanding of individual variation of ovarian reserve function.
