Island Fertility is a full-service fertility practice in collaboration with Stony Brook Medicine, directed by James Stelling, MD. It has been a long-time dream of Dr. Stelling along with his partner, Bradley Trivax, MD, to build a community practice that can provide all types of fertility treatment in a warm, compassionate atmosphere, encompassing state-of-the-art andrology and embryology laboratories ready to provide the highest quality and most advanced technology available for our patients. Our physicians are board-certified reproductive endocrinologists and are the most qualified doctors to diagnose and treat fertility preservation and infertility problems. Our team consists of Dr. Richard Bronson, Dr. Avner Hershlag, Dr. James Stelling, Dr. Bradley Trivax, Dr. Lauren Zakarin Safier and Dr. Chantae Sullivan-Pyke.
Our primary location is a full-service fertility practice. We have the capabilities to diagnose any type of infertility, for the most part, on-site, with minimal need to refer you out for further testing. We provide on-site cycle monitoring, ovulation induction, intrauterine insemination (IUI), fertility preservation, sperm cryopreservation, oocyte cryopreservation, in vitro fertilization (IVF), embryo cryopreservation and preimplantation genetic testing (PGT) of embryos. Our endocrinology lab is running state-of-the-art reproductive hormone analysis on the Roche Cobas e411.
We find that most patients experiencing infertility only need minimal treatment and regulation of cycles. For patients who need more advanced treatment, our brand new IVF lab is ready to provide this service. We have assembled the most advanced technology available, including Nikon and Olympus microscopes, Eppendorf micromanipulators, a Hamilton Thorne LYKOS and Saturn 5 laser system allowing our embryologists to choose the method that best suits your embryos' needs. We have built our laboratory to conform to the highest air quality standards to ensure optimal growth and development. Our tissue bank is protected with the maximum security possible, including 24-hour temperature monitoring, to ensure that your frozen specimens are stored safely away until you are ready to utilize them.
