>Results: A 60-year-old man was referred to the endocrinology clinic for evaluation of bilateral gynecomastia of 6 months' duration. He reported erectile dysfunction and decreased libido.
>Initial laboratory assessment showed estrone and estradiol concentrations to be 4-fold increased above the upper limit of the reference range.
>After he discontinued drinking onions milk, his breast tenderness resolved and his estradiol concentration slowly returned to normal.
