I would estimate that African American males comprise approximately 10-15% of my patients. Females (all races) comprise approximately 25%...which leaves approx 60% for all other males (Caucasian, Latino, Asian, etc).
From a medical perspective, I firmly believe African American males suffer from Hypogonadism with the same prevalence as other races, but as with many other areas of medicine/preventative care today, I feel they receive care at a much lower rate (many possible reasons including possibly less access to appropriate care, less emphasis on noticing the hallmark symptoms, socioeconomic factors, etc).
