The Staff of The MacLeod Laboratory

Dr. TothThe director and primary physician of the MacLeod Laboratory is Dr. Attila Toth, who is Board Certified in Anatomical and Clinical Pathology and Obstetrics and Gynecology. He has thirty years of experience treating infectious diseases and infertility. He is a clinical Associate Professor of Obstetrics and Gynecology at New York Presbyterian Medical Center and the protégé of Dr. John MacLeod, a pioneer in male infertility, who set the currently accepted standards for evaluating seminal fluid.

Dr. Toth is the first physician to emphasize the correlation between gynecological and urological infections and the importance of treating the couple as a unit when approaching infertility problems. Successful treatment of genital tract infections, in either sex, requires a full knowledge of the bacterial flora of both partners. 

In the late 70's there was a sharp turn in the treatment of infertility when most specialists gave up exploring the underlying causes of infertility and adopted artificial reproductive technologies, including IVF procedures, yielding notoriously suboptimal outcomes.

The MacLeod Laboratory took the common sense approach of exploring and eliminating the cause of infertility to restore a couple's chance for natural conception. Such pregnancies yield uncomplicated deliveries with healthy newborns.  We pride ourselves in the fact that pregnancies taking place after our therapies have practically no complications and the newborns never need intensive care.

In 2002 Dr. Toth introduced direct antibiotic injection therapy for chronic prostatitis. We are the only clinic in the United States offering this service.  As the number of treated patients increases, our knowledge about chronic prostatitis expands. As time passes we are able to help more and more patients significantly.
