Interim Director: Sarah England, PhD

As the obstetric and gynecology department’s basic science division, the Center for Reproductive Health Sciences (CRepHS) endeavors to improve the overall and reproductive health of women worldwide by making reproductive health a priority in investigative science. Together with the Division of Clinical Research, CRepHS supports the department’s overall research enterprise.

We are building a team of outstanding investigators dedicated to basic and translational reproductive health research.

Research infrastructure

CRepHS provides an infrastructure of core facilities and resources to support basic and translational research while facilitating collaborations across disciplines and institutions.

Core facilities

Our core facilities support cross-disciplinary research in reproductive health and related fields. CRepHs members, as well as national and international collaborators, have access to these facilities, which are located in the BJC Institute of Health.

Visit the CRepHS website to learn more about our core facilities:


CRepHS faculty members manage several biobanks that acquire and store specimens throughout a woman’s lifecycle (adolescence, pregnancy, pre- and post-menopause), as well as detailed clinical histories. These specimens and data can be leveraged for translational studies and provide drivers for the Precision Medicine Initiative.

Visit the CRepHS website to learn more about these biobanks:

Department-wide resources for researchers

In addition to the core facilities provided by CRepHS, resources available to investigators in the ob/gyn department include:
