THAT'S OUR FORMULA FOR ACHIEVING HIGH SUCCESS RATES
DOCTORS. Our doctors are world-renowned, "Double-Board-Certified" in OB/GYN and in Reproductive Endocrinology and Infertility and have been practicing in the fertility field for a minimum of 25 years.
EMBRYOLOGISTS. These are the biologists that "baby-sit" your eggs and embryos. We have the most qualified and highly-skilled embryologists around because, as you may already know, your embryos can spend up to 8 days in the embryology laboratory, that is a large percentage of your cycle.
Most of the advances in fertility treatments over the past several years have been in the embryology laboratory including genetic testing of embryos, and vitrification technique for embryo freezing. Our embryologists are constantly keeping themselves up-to-date with the current technologies that are applicable to our patients. They are well-versed in all the current techniques and in addition, our embryologists have re-imagined the IVF laboratory techniques and procedures resulting in one-of-a-kind tools and pioneering techniques to improve our patients' chances of success.
SMART IVF TECH. We use unique techniques and procedures in our embryology laboratory, most of which we developed ourselves, which we believe can improve your chances of conception. Each technique may only result in tiny, insignificant (statistically speaking) improvement - but together, they can add up to making the difference for your cycle to be successful or a failure. Find out how these "small baby steps" add up to make your dream come true.
Come take advantage of all the latest technologies available that can help improve the outcome of your fertility care. Latest equipment in the culture of your embryos are available and so are the most recent techniques in processing, of gametes and embryos that are designed to eliminate or decrease the stress that your eggs and embryos undergo in order to maximize the chances of them implanting and resulting into a healthy baby.
SUCCESS RATES. Our rates are higher, 57.5% for patients under 35 years old, than the national average rate of 40.5%.We believe it to be mainly because we pay very close attention to every detail of your treatment and we employ every technique we have learned and also those we developed ourselves that can improve your chances of going home with a baby
