Evidence is accumulating that benign enlargement of the prostate may also be inherited in an autosomal dominant pattern in some families. We strongly encourage clinicians to include a family history of benign prostate enlargement in men who are being treated for bladder outlet obstruction.

Families with three or more living members who have undergone surgery or medical therapy for benign prostatic enlargement are eligible for this study. If a patient's family fits these criteria, and would consider participation, please leave your name and phone number, and the patient's name, phone number and address on our answering machine: 410-955-0355, or by leaving this information in a note to our email address: We will contact the patient by mail with details about the study and a questionnaire.
