Early in his career, Dr. Schlegel worked with pioneers in the field of urology and male reproductive function, Dr. Fray Marshall and Dr. Patrick Walsh at The Johns Hopkins Hospital in Baltimore, Maryland. As a resident, Dr. Schlegel established some of the anatomical basis that was necessary to develop the contemporary procedures of radical prostatectomy and radical cystectomy that are used to cure localized prostate and bladder cancer. Dr. Schlegel continues to be active in the surgical treatment of prostate cancer because of his advanced understanding of this anatomy. He has also been the principal investigator on trials that led to some of the newest treatments for advanced prostate cancer, histrelin hydrogel implants.

Dr. Schlegel was granted a research scholarship from the American Foundation for Urological Disease/American Urological Association in 1989 and completed his fellowship in the area of male infertility and reproductive function with the guidance of Dr. Marc Goldstein and Dr. Wayne Bardin at The Population Council, Center for Biomedical Research, and Center for Male Reproductive Medicine and Microsurgery, Department of Urology, The New York Hospital-Cornell Medical Center in 1991.

Dr. Schlegel is also an internationally acclaimed expert in the treatment of male infertility, especially the interface of male factor treatment with assisted reproductive techniques.

In over 228 published or submitted original manuscripts, as well as numerous book chapters and invited articles, Dr. Schlegel has described the characteristics of men who are candidates for sperm retrieval, designed and described novel techniques for microsurgical procedures that help couples where men have the most severe forms of male infertility. He has also published extensively on novel hormonal approaches for treatment of infertile men as well as to provide novel investigation of the genetic aspects of infertility. Most importantly, the team of scientists, reproductive endocrinologists, nurses and technicians that Dr. Schlegel has worked with at Weill Cornell has achieved one of the highest pregnancy rates in the world for treatment of couples using sperm that were retrieved by Dr. Schlegel.
