In his 25-year career, Dr. Patrizio has produced research accomplishments of extraordinary importance and innovation spanning basic and clinical reproductive medicine. For instance, he discovered that the congenital absence of the vas deferens in men is a mild form of cystic fibrosis, and he found that some cases of male infertility are due to deletions on the Y-chromosome. This finding paved the way for genetic assessments as part of the clinical assessments for infertile men.
He has published a leading assisted reproductive technologies (ART) textbook, five additional books, and 211 peer reviewed original manuscripts. He serves as an associate editor of Reproductive BioMedicine online and the American Journal of Obstetrics & Gynecology, and is on the editorial board of the Journal of Assisted Reproduction and Genetics.
