Other doctors may have told you that fathering a child is impossible—that you have no measurable sperm and are not a candidate for fertility treatment. But we do not rest so easily, and do not believe you need to, either.
The Stanford International Azoospermia Center is a world leader in diagnosing and treating azoospermia, and we invite you to visit. Not every man can become a biological father. But we have successfully treated plenty of cases where patients were previously told they did not have a chance—taking the impossible and making it possible.
We take a team approach at our Stanford International Azoospermia Center, bringing together a group of world-renowned experts. That ensures you get the possible care, with our specialists offering the latest approaches to diagnosis, treatment and promising research. We also partner with other Stanford centers and clinics to help you and your partner conceive.
Our program is led by a urologist with fellowship training in male infertility and microsurgery. Having a dedicated center allows us to include other specialists as well, for a multidisciplinary approach. Some of our colleagues treat female infertility—you and your partner may want a second opinion, or you may strongly suspect you have azoospermia but want to simultaneously rule out other causes as a couple. We also provide conception help.
Dr. Eisenberg is fellowship trained in male infertility and microsurgery and is immensely experienced in caring for men with azoospermia. He believes reproduction is one of a being’s fundamental elements, and seeks to help men both understand azoospermia and treat it with cutting-edge science.
Vittorio Sebastiano, MD
Dr. Sebastiano trained in reproductive and developmental biology at the University of Pavia, Italy. He also has wide experience with embryonic development and stem cell biology. His research focuses on understanding how germ cells and human embryos develop and to translate this knowledge to clinical practice, the treatment of infertility and assisted reproduction.
Valerie Baker, MD
Director, Stanford Reproductive Endocrinology and Infertility Program
Dr. Renee Reijo Pera is a world expert in stem cells, as well as in sperm differentiation and development. She was a pioneer in identifying genetic causes of azoospermia and is a leading expert in the use of stem cell techniques to cure azoospermia.
We are proud to have earned recognition from the Human Rights Campaign Foundation "Healthcare Equality Index."
