about the doctor
Dr. Anthony Auyeung is a highly experienced Reproductive Endocrinologist. He obtained his MD from the University of Toronto in 1991 and completed his residency in Obstetrics and Gynecology at the University of Ottawa in 1996. He then pursued a three-year fellowship in Reproductive Endocrinology and Infertility at Washington University in St. Louis, USA. After completing his training, he returned to Toronto in 1999 to begin his practice. Before entering medicine, Dr. Auyeung graduated with a Pharmacy degree from the University of British Columbia in 1983 and became licensed to practice in both British Columbia and Ontario. He later earned a Master of Science in Pharmacology and Therapeutics in 1986. His research background in electro-neurophysiology offers him a unique understanding of drug actions, enabling him to tailor medication protocols to each individual patient—an approach that has defined his clinical practice for over two decades. Dr. Auyeung is a Fellow of the Royal College of Physicians and Surgeons of Canada and board-certified by the American Board of Obstetrics and Gynecology.

Our services
In-Vitro Fertilization (IVF) / ICSI
IVF involves stimulating the ovaries to produce multiple eggs, retrieving them, fertilizing them with sperm in a lab, and transferring the healthiest embryo(s) into the uterus. ICSI is a specialized IVF technique where a single sperm is injected directly into each egg, often used in cases of severe male infertility or previous fertilization failure. Each IVF cycle is tailored based on your unique clinical profile to optimize outcomes.
Third Party Treatments (donor gametes, gestational surrogacy)
For individuals and couples requiring assistance through donor eggs, donor sperm, or gestational carriers, comprehensive third-party reproductive services are offered. Collaboration with trusted agencies and legal professionals ensures an ethical, smooth, and respectful process for all parties involved.
Egg Freezing
Egg freezing allows individuals to preserve their fertility by retrieving, freezing, and storing eggs for future use. It’s an empowering option for those not ready to conceive due to personal, medical, or professional reasons. Using advanced vitrification technology, high survival rates and the potential for a healthy pregnancy are ensured when you're ready.
Sperm Freezing
Sperm freezing is a simple and effective way to preserve male fertility. Whether undergoing medical treatment, considering gender transition, or planning for future parenthood, storing sperm offers peace of mind and future reproductive options.
Embryo Freezing
During an IVF cycle, excess high-quality embryos can be frozen for future use. Embryo freezing provides flexibility in family planning, improves pregnancy chances in subsequent cycles, and reduces the need for repeated ovarian stimulation. These embryos can be stored for many years with high survival and success rates upon thawing.
Long-term Storage of Eggs and Embryos
We provide safe, secure, and accredited long-term cryopreservation services for eggs and embryos. Whether you're planning a future family or extending your reproductive timeline, our storage program offers reliable access when you're ready to proceed with treatment.
Single Parent
At CARS, we proudly support individuals who wish to pursue parenthood on their own. Whether through IUI, IVF, or third-party options, we provide medical and emotional support tailored to your unique needs as a single parent by choice.
Family Building for Same-Sex Partners
We are committed to helping LGBTQ+ individuals and couples achieve their dream of starting a family. Through services such as donor insemination, IVF with donor eggs or sperm, reciprocal IVF, and surrogacy, we create inclusive treatment plans tailored to your family-building goals.
Second Opinion
If you’ve received a diagnosis or treatment plan elsewhere and are looking for additional insights, we offer second-opinion consultations. Our expert team will carefully review your medical history and current findings to provide a thorough, honest, and supportive assessment to help you make informed decisions.
