A patient who’s undergone a bilateral orchiectomy finds that he still can have erections. With the reduction in his testosterone levels, how is that possible?
Actually, almost half of the men who’ve had both testes removed remain capable of erection, perhaps because adrenal cortical androgens are producing adequate levels of testosterone. Indeed, low testosterone levels account for less than 10% of organic impotence–a much lower percentage than was thought only a few years ago. The usual cause is primary testicular failure or anterior pituitary failure, which can be treated effectively with testosterone cypionate injections every two to three weeks.
The notion of a “male menopause” has recently become popular due to studies showing that men’s production of testosterone and other human growth hormones tends to decline with age. Yet many of these studies, says a report in the June issue of Maturitas, are flawed and their results questionable.
The studies, according to Massachusetts researcher John McKinlay, have relied on very small groups of men, many of whom were sick or on medications. Also ignored have been such factors as smoking or drinking habits, both of which can affect testosterone and HGH levels. To correct these deficiencies McKinlay and his colleagues have organized a study of 1,700 mostly healthy older men randomly selected in the Boston area.
Their study is not yet finished but they have published some preliminary results which show that age alone seems to have little effect on hormone production in healthy men. This suggests, they say, that human growth hormone replacement therapy should not be considered in otherwise healthy older men (please see GenF20 Plus Reviews for more information).
