Growing up as one of eight children, I learned the value of collaboration and teamwork. My wife and I are also very fortunate to have seven children, so I truly understand the importance of family to my patients.
Obstetrics and gynecology, and especially my focus on infertility, bring together the science and personal interactions with patients, which I love. I am incredibly invested in helping couples discover why they’ve been unable to conceive. At NYU Langone, we offer some of the most exciting fertility breakthroughs of our time, including the latest fertility drugs and genetic testing, to support couples in creating the families they want.
Before I practiced as an OB/GYN, I trained in psychiatry, which prepared me to help couples cope with the emotions that accompany reproductive choices. I empower my patients to be involved in the entire process, and I help them to weigh their options based on their unique values and goals.
Breakthroughs in contraceptive technology have given women the ability to delay having children, but by a woman’s late 30s and early 40s, the ability to conceive declines. Our research lab focuses on the causes of age-related infertility, primarily the aging of the eggs themselves. We’re working on new treatments to slow this process. We’ve also made incredible advances in in vitro fertilization, including our ability to decrease the likelihood of miscarriage by using genetic testing of the embryo to determine its integrity before transfer.
