    Areas of Interest & Research


    Dr. Norian’s approach in helping his patients reach their dream of having a family combines both the precision and science of reproductive medicine with a warm and compassionate style of doctoring. His areas of expertise include: in-vitro fertilization (IVF), pre-implantation genetic testing (PGT), LGBTQ fertility treatments, sex selection, egg freezing, optimal treatment for low responders, and polycystic ovarian syndrome (PCOS).


    He is a strong advocate for all seeking assistance with fertility treatments whether they are those struggling with infertility or LGBTQ people seeking to add their families through gamete donation and/or gestational surrogacy. In addition, he has a keen interest in nutrition and our lifestyle’s impact on fertility and sperm and egg quality. Both he and his multilingual clinical team provide high quality, individualized care resulting in high success rates and it is because of this his patients come from around the world seeking treatment with him.

    Curious at heart, Dr. Norian and his team continue to focus on clinical reproductive research and are involved with large clinical trials and also internal embryologic studies. His interests include trail running, reading and enjoying time in the outdoors with his family.
