About Our Center

Endometriosis is a chronic, debilitating estrogen-dependent disease wherein tissue similar to the uterine lining (endometrium) is found mainly on pelvic tissues and organs where it causes an inflammatory response, scarring, pelvic pain, and infertility. It affects millions of reproductive age people and severely impacts quality of life and professional life, and has a huge health economic impact of about $69B annually in the U.S. While its etiology is uncertain, profound dysfunction of the innate and adaptive immune systems is associated with inefficient lesion clearance and pelvic and systemic inflammation.

The heterogeneity of endometriosis lesions and disease phenotypes is reflected in variable pain symptom presentations, unpredictable fertility potential, uncertain disease pathophysiology, and unpredictable responses to medical therapies, symptom and disease recurrence after surgical resection, and risks for co-morbidities. Clinical classifications of endometriosis are maladapted to the heterogeneity of disease expression, and thus efficient treatments for associated pain symptoms are lacking.


Our UCSF Stanford Endometriosis Center for Discovery, Innovation, Training and Community Engagement (“ENACT”) takes a comprehensive systems biology and precision medicine approach to endometriosis. We study endometriosis unmet needs and challenges through transdisciplinary collaboration and scientific and technologic innovations, integrating multi-omics data to dissect endometriosis disease mechanisms, identify phenotypic and environmental disease signatures, develop accurate disease stratification and diagnosis, and identify novel and repurposed drug classes to ameliorate pain symptoms.


To achieve these goals, our Center is comprised of 3 independent and interactive research projects and 2 Cores, focused on the central theme of Endometriosis Precision Medicine.

Our long-standing Human Endometrial Tissue and DNA Bank and REDCap database and ongoing accruals with our collaborating network of surgeons are a major resource for this Center's project. The Center has an Administrative Core and an Education and Community Outreach Core that engages students from the Bay Area in our research programs and empower women in our community and address health disparities associated with endometriosis. To achieve these goals, we have assembled a multi-disciplinary team of investigators at UCSF and Stanford University, many of whom are new to endometriosis research, as well as educators, trainees, and community representatives who are all committed to improve the lives of adults and teens with endometriosis. Integrating multiple disciplines, fostering collaborations among those who are new to endometriosis, training the next generation and partnering with our community are key to the outcomes and impact of our Endometriosis Center.

Participation and Eligibility

We invite you to consider participating in our study about gynecological and reproductive health, being conducted by Drs. Linda Giudice and Marina Sirota at UCSF and Dr. Brice Gaudilliere at Stanford. The study’s aim is to advance understanding about the uterine lining (endometrium) and health. The study is funded by the National Institutes of Health (NIH).

You may be eligible if you:

  1. Are between the age of 18-40 with regular periods

  2. Are not currently using any form of hormonal contraceptive (birth control pill, patch, IUD, implant, ring, etc.), GnRH analog (e.g., Buserelin, Goserelin, Leuprorelin, Naferelin, or Triptorelin), or aromatase inhibitor (e.g., letrozole and anastrozole)

  3. Are HIV negative

  4. Are generally healthy with no significant medical conditions (e.g., cancer)

  5. Not currently pregnant


If you are interested in learning more about the study, please contact our study coordinator directly (UCSF: Stanford: before your gynecologic surgery/appointment and indicate your availability for a zoom or phone call with our study coordinator to review the study in more detail.


Participating in this study is entirely voluntary. It will not affect your medical care if you decide not to reply or decide not to participate in the study.

We hope that you will consider participating in our study as we strive to further understand the biological impacts of the endometrium in health.

Thank you,
The Endometrial Tissue Bank Study Team


What are my rights if I take part in this study?

Taking part in this study is your choice. You may choose either to take part or not to take part in the study. If you decide to take part in this study, you may leave the study at any time. No matter what decision you make, there will be no penalty to you and you will not lose any of your regular benefits. Leaving the study will not affect your medical care. You can still get your medical care from our institution.

How will I know that my confidentiality will be protected?

This research is covered by a Certificate of Confidentiality from the National Institutes of Health. This means that the researchers cannot release or use information, documents, or samples that may identify you in any action or suit unless you say it is okay. They also cannot provide them as evidence unless you have agreed. This protection includes federal, state, or local civil, criminal, administrative, legislative, or other proceedings. An example would be a court subpoena. The Certificate does not stop reporting that federal, state or local laws require. Some examples are laws that require reporting of child or elder abuse, some communicable diseases, and threats to harm yourself or others. The Certificate cannot be used to stop a sponsoring United States federal or state government agency from checking records or evaluating programs. The Certificate does not stop disclosures required by the federal Food and Drug Administration (FDA). The Certificate also does not prevent your information from being used for other research if allowed by federal regulations.

Can I stop being in the study?

Yes. You can decide to stop at any time. Tell the study doctor or co-investigators if you are thinking about stopping or decide to stop. If you decide to stop before the procedure, no specimen will be obtained and no blood sample will be taken for this study, and no information will be collected from your medical records. If, in the future, you decide that you don’t want to have your tissue or blood used for research, inform the UCSF investigators in writing and all of your specimens and data will be destroyed if they have not been used or unlinked.
