The somatopause: to treat or not to treat?
There is much evidence that some aspects of ageing are similar to those observed in selective hormone deficiencies during adulthood. Replacement therapy in hypogonadism and/or growth hormone (GH) deficiency in adulthood is very successful in reversing the related clinical symptomatology. However, preliminary studies of GH treatment in the normal elderly have been largely disappointing: an increase in muscle mass is only accompanied by improved muscle strength if exercise is also increased during this period. No real benefit of GH therapy, additional to that of exercise, has been reported. Epidemiological studies indicate a relationship between high-normal insulin-like growth factor-I levels and cancer development. No definitive answers can presently be given regarding the safety of long-term GH therapy in otherwise healthy individuals during the somatopause.
