Dr. Jonathan Kort is an established specialist in reproductive endocrinology, and the author of many medical publications and textbook chapters in the field of infertility science.

His clinical focus areas include diminished ovarian reserve, hypothalamic amenorrhea, Polycystic Ovary Syndrome (PCOS), reproductive surgery, and gamete/embryo selection. He has a particular interest in patients with a history of poor embryo development during IVF. He sits on the editorial board of Fertility and Sterility, has published textbook chapters on gamete and embryo selection, and was the recipient of the Stanford Child Health Research Institute Grant (2017) which helped develop new ways of using preimplantation genetic screening for embryo selection. Dr. Kort completed his Reproductive Endocrinology and Infertility (REI) fellowship at Stanford University Hospital in Palo Alto, where he conducted cutting-edge research on non-invasive measurements of eggs to predict their future development potential, as well as research in genetic screening. During his time at Stanford he also completed training in embryology, and is certified as a technical supervisor in embryology and andrology. He completed his OBGYN residency at Stanford University Hospital, during which he completed original research into egg freezing, the impact of weight loss on fertility treatment, and ovarian reserve. Dr. Kort received his M.D. from Georgetown University Hospital in Washington, D.C.

Dr. Kort followed his father into the field of reproductive medicine. After learning how rewarding this field can be by meeting his father’s former patients (and their children) throughout his childhood, he decided to dedicate his career to helping patients achieve their reproductive goals. He credits his father with helping develop his bedside manner.  His philosophy is to treat patients like family and make sure no question is left unanswered or concern unaddressed. He recognizes how important access to timely answers can be during a stressful process, and makes sure his patients always have access to him and the rest of their care team.

Dr. Kort loves spending time with his family, the outdoors and is an avid triathlete, having completed two Ironman triathlons. If he’s not in the office seeing new patients, he’ll probably be on his bike or in the pool, training for his next race.
