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

Dr. Schlegel was awarded a fellowship by the Royal College of Surgeons in 1992 for collaborative study with urologists in London, which he performed in 1993.

In over 300 published peer-reviewed 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 the successful achievement of pregnancy after sperm retrieval. He has also published extensively on microsurgical treatment of infertile men as well as on genetic aspects of infertility.

Early in his career, Dr. Schlegel worked with pioneers in the field of urology and male reproductive function. With Dr. Fray Marshall and Dr. Patrick Walsh at The Johns Hopkins Hospital in Baltimore, Maryland, Dr. Schlegel worked as a resident in general surgery and urology.

Dr. Schlegel continues to be active in the surgical treatment of prostate cancer and participates in development of novel therapies for prostate cancer.
