    About me

    Originally from California, my Obstetrics and Gynecology training brought me out to SIU Medicine; and it was my passion and dedication to women’s health compelled me to stay.  It is a great privilege to be able to provide the most up-to-date, evidence-based health care for the women in Central Illinois as well as to help train SIU medical students and future OB/GYNs in our residency program.  Aside from my day-to-day private OB/GYN practice, I am able to pursue my interest in advocacy, colposcopy, health equity & diversity, and under-served high-risk OB patients. -Dr. Jongjin "Anne" Martin

    Endometriosis and the Microbiome

    Active recruiting

    PURPOSE: Endometriosis is an inflammatory disorder in which the tissue that lines the inside of the uterus (the endometrium) spreads to the pelvic and peritoneal cavities outside of the uterus. This is a biological sample collection study examining how bacteria located within the vagina, the urogenital tract and the gastrointestinal tract may affect the development of endometriosis. Investigators are also exploring how an individual’s microbiome affects their estrogen metabolism and inflammation.
