Fangyin Meng, MD, PhD, is a skilled reproductive endocrinology and infertility specialist with her own private practice in Orange County, California.
Dr. Meng received her MD and PhD degree as an honored student from Peking University Medical School in Beijing, China, the best medical school in China. She got her PhD degree in genetics, specifically on human embryo genetics. She completed her OB/GYN residency training at Peking University First Hospital and the Albert-Einstein College of Medicine affiliated Bronx-Lebanon Hospital Center. She received the best resident award and surgical skill award when she graduated from the residency program. After her residency training, Dr. Meng completed her reproductive endocrinology and infertility fellowship training at Albert-Einstein College of Medicine.
Dr. Meng has broad interests in human reproductive medicine, which includes human embryo genetics, endometrial receptivity, and cryobiology. Dr. Meng started preimplantation genetic testing, egg cryopreservation, and endometrial receptivity window research in early 2000. She has authored and submitted dozens of abstracts while presenting her data at international and national meetings.
As a genetic expert, Dr. Meng has a passion for human genetic and epigenetic diseases, such as polycystic ovarian syndrome. Dr. Meng understands every disease has two different aspects: a genetic predisposition and environmental factors. Therefore, Dr. Meng promotes patient-centered treatment, considering all aspects of her patients, including physical, psychological, lifestyle, cultural, and emotional factors when developing effective treatment plans.
Recurrent implantation failure is another field Dr. Meng focuses on. She has multiple publications on endometrial receptivity research—another side of the implantation story besides good quality embryos. Through comprehensive evaluation of genetics, hormonal, immunological, and uterine factors, Dr. Meng has helped several difficult recurrent implantation failure patients succeed.
Dr. Meng firmly believes that your success is her success. She understands that every patient and couple are different, so she’s committed to listening to your story, so she can understand your story and help you succeed.
As a mom, she knows infertility impacts every aspect of your life, and she truly cares about your success and happiness!
