What is an embryologist?

The practice of in vitro fertilization is a team effort, comprised of clinical personnel (the reproductive endocrinologists and nurses) and laboratory personnel; i.e. embryologists. At CARMF, we are one of a select group of IVF centers in New Jersey to have a Ph.D. level scientist on-site full-time to serve as Director of the Embryology Laboratory.

Embryologists have specialized experience in the study and handling of eggs, sperm and embryos, and responsible for the day to day laboratory activities during a patient’s IVF cycle. An embryologist’s basic functions include the preparation, insemination or micromanipulation and determination of fertilization of human gametes. The embryologist is also involved in the embryo transfer process and is responsible for grading and selecting embryos to transfer as well as cryopreserving (freezing) extra embryos.

The laboratory environment is critical to the success of an IVF program. Therefore, it is the responsibility of the embryologist, through rigorous quality control procedures, to ensure that the highest standards of laboratory performance are maintained. Our embryologists are led by Dr. Bo Feng who has specialized training in the latest cutting edge technologies. Our laboratory provides services related to all aspects of assisted reproductive technologies including: endocrine hormone testing, semen analysis, oocyte identification, in vitro fertilization (IVF), oocyte/embryo culture, blastocyst culture, intracytoplasmic sperm injection (ICSI), assisted hatching, embryo biopsy for pre-implantation genetic diagnostic (PGD), embryo cryopreservation/vitrification (see image video gallery).
