Vuk Jovanovic MD, FACOG

Medical Director,
California Fertility Clinic

Specialist In Reproductive Endocrinology And Infertility Board Certified By The American Board Of Obstetrics And Gynecology

Dr. Vuk Jovanovic leads California Fertility Clinic, bringing years of clinical experience from the United States and Europe. He completed residency in obstetrics and gynecology at Duke University, followed by subspecialty training in reproductive endocrinology and infertility at Columbia University in New York. While in New York, he also studied public health at Columbia’s Mailman School. He earned his medical degree in Germany at Johannes Gutenberg University.

His early medical education included research at the University of Pennsylvania and City of Hope in California. He also took part in clinical exchange programs at Harvard, UC San Diego, and Baylor College of Medicine. This wide academic foundation built his ability to approach patient care with precision and adaptability.

Dr. Jovanovic holds medical licenses in the United States, Germany, the United Kingdom, and Spain. He speaks German, Serbian, Croatian, and Russian, and maintains strong medical connections throughout Europe, Asia, and the Middle East. He chose Los Angeles as his base not only for its openness to egg donation and surrogacy, but for the cultural diversity that allows him to support patients from all backgrounds.

He founded Kinderwunschzentrum Los Angeles to offer comprehensive support for patients at every stage of their journey. Before launching California Fertility Clinic, he worked with Dr. Michael Vermesh at the Center for Fertility and Gynecology, where many leading fertility doctors have trained. That experience led to a leadership role at Tree of Life Center, where he now oversees both clinics, focusing entirely on medical quality and individual care.

Couples and individuals seek his care not only for strong outcomes, but for his ability to guide them through complex fertility options with clarity and confidence. Over time, this approach has built consistent trust with patients both locally and abroad.

He remains actively involved with peers through ASRM and ESHRE to ensure treatments are aligned with the latest research and standards.
