Board Certified in Obstetrics and Gynecology from The American Board of Obstetrics and Gynecology

Recently included as one of the top doctors in New York, Dr. John Zhang is a leader in the fertility field, constantly pushing the boundaries of reproductive care to establish the most safe and innovative fertility treatment techniques. Dr. Zhang is an early pioneer of Minimal Stimulation IVF (Mini-IVF™) and Natural Cycle IVF, embryo and egg freezing, freezing by vitrification and cytoplasmic transfer and, more recently, is contributing heavily to the development of non-embryonic stem cell research. In addition, he has directed many of New Hope Fertility Center's achievements, including the birth of a genetic child by a 49 year-old, cutting-edge ovarian-transplant IVF procedures, and numerous successes with IVF for patients with high FSH levels.

After completing his medical degree at the Zhejiang University School of Medicine in China in 1984, Dr. Zhang undertook postgraduate training in the United Kingdom. He studied male infertility at Birmingham University, earning a Master's Degree there in 1985. He was one of 80 overseas student recipients of the British Postgraduate Scholarship in 1989.

At Cambridge University, Dr. Zhang studied in vitro maturation and fertilization of mammalian oocytes, earning a Ph.D. in In-Vitro Fertilization (IVF) in 1991. In 1997, after more than ten years of training and research in the biology of mammalian reproduction and human embryology, Dr. Zhang successfully completed a residency in the Department of Obstetrics and Gynecology at the New York University School of Medicine. In 2001, Dr. Zhang was chosen to become the first Fellow in the Division of Reproductive Endocrinology and Infertility of New York University School of Medicine.

Dr. Zhang founded the New Hope Fertility Center in 2004. He has been recognized as a global leader with his more gentle approach to assisted reproductive technology (ART) and is one of only a handful of reproductive endocrinologists in the United States who holds a Ph.D. in embryology while also being certified as a high complexity laboratory director.

Dr. Zhang's research interests include long-term cryopreservation of oocytes, embryos and ovarian tissue, as well as oocyte reconstruction by nuclear transfer. His research and clinical work in mammalian in vitro fertilization is highly recognized in the fertility field and he is invited to speak each year at worldwide conferences.
