David M. Fenig, MD is a dynamic urologist and experienced male infertility and male sexual health specialist who came to Baltimore and Chesapeake Urology from New York because of the unique opportunity to work with a world class group of urologists and multiple IVF Centers throughout the region. 

As a Director of the Vasectomy Reversal Center of America, a division of Chesapeake Urology, and Director of Male Fertility, Microsurgery, and Sexuality at Chesapeake Urology, Dr. Fenig specializes in male fertility including microsurgical vasectomy reversal and varicocele repairs, sperm retrieval for In Vitro Fertilization (IVF), as well as vasectomy. With a strong research background in male infertility, he is on the leading edge of this specialty.

Recognized as a leading expert in the field of male reproductive health, Dr. Fenig is a member of an elite group of just two percent of board-certified urologists in the U.S. who are fellowship-trained in male infertility and microsurgical techniques. There are fewer than a dozen such trained urologic surgeons in the Mid-Atlantic region.

In addition to being a male fertility consultant to all of the Baltimore/DC IVF centers, Dr. Fenig also treats a number of other male sexual and urologic health issues including: erectile dysfunction, low testosterone, and Peyronie's disease, an abnormal curvature of the penis. He also has a special interest in the preservation of erectile function after prostate cancer treatment, microsurgical treatment of chronic testicular pain, penile prosthesis, benign prostate disorders, and kidney stones.

Known by his patients and colleagues as a caring, compassionate and friendly doctor, his goal is to fulfill patients’ expectations by performing successful vasectomy reversals and providing exceptional care for all men experiencing urologic , fertility and sexual health problems.
