A method of modulating glandular secretions by administering acoustic shock waves to a gland, includes the steps of activating acoustic shock waves of an acoustic shock wave generator to emit acoustic shock waves and subjecting the gland to acoustic shock waves stimulating the gland to have a modulated response. The modulated response is one of an adjustment in hormonal release which increases low level output, decreases high level output or stabilizes erratic output. The emitted acoustic shock waves are focused or unfocused low energy acoustic shock waves. The gland underlies the patient's skin. The shock wave generator is acoustically coupled to the patient's skin using a coupling gel or liquid. The gland is one of a testicle, ovary, pituitary gland, adrenal gland, thyroid gland, thymus, pineal gland, parathyroid, or hypothalamus. The method can be repeated one or more times.
