    The Transcendental Meditation (TM) and a more advanced program, the TM-Sidhi program, have been reported to produce a number of acute and long-term metabolic and electrophysiologic changes. To investigate the possibility that the practice of these techniques may be associated with long-term endocrinologic changes, we prospectively evaluated 11 male subjects before and over a 3-year period after starting the TM-Sidhi program. A progressive decrease in serum TSH, growth hormone, and prolactin levels occurred over the 3 years while no consistent change in cortisol, T4, or T3 levels was observed. These results suggest that the long-term practice of the TM and TM-Sidhi program may have effects on neuroendocrine function. Further studies using 24-hr monitoring with frequent blood sampling will, however, be needed to fully assess the significance of the simultaneous decline of the anterior pituitary hormones with maintenance of levels of hormones from peripheral endocrine glands.
