Dr. Jan Tesarik | Reproducción humana | Lifetime achievement Award
Dr. Jan Tesarik , Reproducción humana , Director at MARGen Clinic, Spain
Dr. Jan Tesarik is a world-renowned reproductive endocrinologist and fertility expert with over four decades of groundbreaking work in assisted reproductive technologies (ART). He is credited with numerous scientific “firsts,” including the first successful Gamete Intra-Fallopian Transfer (GIFT) in 1982, and the first births via ROSI and ELSI. He pioneered the now-famous “3-parent-baby” nuclear transfer technique and contributed significantly to improving fertility outcomes using growth hormone therapy. Dr. Tesarik’s innovative research spans human reproduction, embryology, and gynecological imaging. With over 400 scientific publications, book chapters, and editorial roles, he has left an indelible mark on global reproductive medicine. He currently serves as the Director of MARGen Clinic in Granada, Spain, continuing to lead in fertility care and research.
Professional Profile
🎓 Education
Dr. Tesarik obtained his MD degree in 1979 and subsequently completed a PhD in 1982, building a solid foundation in human reproductive biology. His training combined clinical medicine with molecular and developmental biology, preparing him for a distinguished career in assisted reproduction and embryology. He studied at Purkyne University in Brno, Czechoslovakia, a leading center for biological sciences at the time. His academic formation was enriched by international research and clinical collaborations, allowing him to innovate at the intersection of reproductive endocrinology, embryology, and molecular genetics. His continued dedication to education and knowledge-sharing is evident through his roles as editor, author, and mentor to many in the reproductive science field.
💼 Experience
Dr. Jan Tesarik’s professional journey spans academia, clinical innovation, and editorial leadership. He began his career at Purkyne University and later worked at the American Hospital of Paris, gaining both academic and clinical prestige. He is currently the Director of MARGen Clinic in Granada, Spain, where he combines cutting-edge fertility treatment with personalized patient care. Dr. Tesarik has led international research efforts, especially in gamete biology, embryo development, and fertility preservation. He has contributed key advances in ART, including ROSI, ELSI, and non-invasive virtual imaging techniques. His response to the COVID-19 pandemic included evaluating anti-COVID fertility-safe treatments. His active roles in Frontiers in Reprofuctive Endocrinology, Frontiers in Reproductive Health, and IJMS as editor/associate editor showcase his continued influence in scientific discourse.
🔬 Research Interests
Dr. Tesarik’s research is centered on human fertility, specifically gamete interaction, fertilization, and embryo development. He pioneered reproductive breakthroughs such as ROSI and ELSI, providing hope for male infertility cases previously deemed untreatable. His development of nuclear transfer techniques laid the groundwork for the “3-parent baby” strategy, aimed at preventing mitochondrial diseases. He has extensively studied growth hormone’s role in improving oocyte quality and uterine receptivity, and more recently, examined COVID-19’s impact on fertility. His innovations in non-invasive imaging, such as virtual hysteroscopy and embryoscopy, have enhanced diagnostics in reproductive health. His multidisciplinary work links clinical medicine, molecular biology, and technology.
🏅 Awards
Dr. Tesarik’s achievements have earned him global recognition in the fields of reproductive medicine and molecular biology. Though not all individual honors are listed, his pioneering work in assisted reproduction, particularly GIFT, ROSI, and nuclear transfer, are themselves landmark contributions acknowledged across the scientific community. He serves on editorial boards of top-tier journals including Frontiers in Endocrinology, Frontiers in Reproductive Health, and IJMS, and is an Emeritus Editor for Reproductive Biomedicine Online. His recognition includes peer citations, invited keynote talks, and institutional affiliations reflecting the global impact of his work. Few researchers can claim such breadth—from first-in-human procedures to mentoring and leading international publications.
