Researcher | Research Overview

Dr. Grimstad engages in research surrounding transgender and differences of sex development/ intersex traits (dsd/I) reproductive health. Her interests center around optimizing reproductive health outcomes for both populations including hormonal and menstrual management, sexual health, surgical care, and family planning.

Researcher | Research Background

Frances Grimstad (she/her) is a Pediatric and Adolescent Gynecologist at Boston Children’s Hospital and an Assistant Professor of Obstetrics, Gynecology and Reproductive Biology at Harvard Medical School.

She engages in clinical and research work surrounding transgender and differences of sex development/ intersex traits (dsd/I) reproductive health. She has been involved in trans health advocacy since her own adolescence, when she decided to pursue medicine to address disparities in care faced by these communities. Dr. Grimstad believes in using research and advocacy to dismantle clinical bias and bring more evidence-based care to gender- and sex-diverse patients.

At Boston Children’s she is the founder of the Transgender Reproductive Health Service and also the gynecologist in the Center for Gender Surgery and the BEING-U clinic (the program for patients with dsd/I). She believes reproductive health and the decisions that surround it are deeply personal and as unique as each individual. She prioritizes individualized reproductive, sexual and fertility goals for her transgender, gender diverse, and dsd/I patients.
