I don't think so: It is highly unlikely the soy protein will be absorbed through your scalp, make its way into your bloodstream while avoiding metabolism, find your gonads {ovary or testis} and somehow down-regulate their testosterone secretion. Aging has a much more profound effect upon your hormonal balance. A morning blood test will determine your hormone levels.
