Women taking estrogen also need to take progesterone replacement. Men develop testicular suppression with decreased libido, impotence, decreased ejaculate volume, loss of body and facial hair, weakness, fatigue and often anemia. Blood levels of testosterone are low. Testosterone should be replaced. It is usually given in an injectable form or in patch form.
Injectable testosterone lasts two weeks in most patients.
Growth Hormone Deficiency Growth hormone is necessary in children for growth, but also appears necessary in adults to maintain body composition. It may also be helpful for maintaining an adequate energy level, optimal cardiovascular status and some mental functions. Symptoms of GH deficiency in adults include fatigue, poor exercise performance and symptoms of social isolation. GH is only available in injectable form and must be given daily. This problem arises from damage to the pituitary stalk or the posterior pituitary gland.
