Marina Straszak-Suri, MD, FRCS(C)

Dr. Marina Straszak-Suri, MD, FRCSC, is an obstetrician-gynecologist, author, and international speaker with more than 35 years of clinical experience in women’s health, fertility, and reproductive medicine.

Over the past two decades, Dr. Straszak-Suri has increasingly focused on a precision and restorative approach to reproductive health, exploring how nutrition, metabolic health, lifestyle, environmental exposures, and other modifiable factors can influence fertility and reproductive longevity. Her work bridges conventional medicine with evidence-informed strategies designed to help women and men optimize their health before conception.

She is the author of Optimize Your Fertility Naturally: A Holistic Guide to Achieving a Healthy Pregnancy, with a foreword by Dr. Mark Hyman. The book grew from a recurring observation in her clinical practice: many patients first begin thinking seriously about fertility only when they are ready to conceive, despite the fact that reproductive health is shaped by choices and exposures occurring years earlier.

Dr. Straszak-Suri is passionate about shifting the conversation from treating infertility to proactively building reproductive health. Through her clinical work, writing, education, and speaking, she advocates for making preconception health a meaningful part of preventive and longevity medicine—for women and men alike.
