The patient population that the Naturopathic doctor is most likely to encounter is that of the man with late onset hypogonadism (LOH). Male menopause, low T and testicular hypofunction all refer to the fact that male total testosterone (TT) or free testosterone (FT) levels are low. Often the treatment is the same regardless of cause. Causes include testicular injury, obesity, hypopituitarism, head injury, opioid use, age, primary testicular failure, and congenital causes such as Klinfelter’s syndrome. Obesity decreases TT due to an insulin resistance-associated feedback loop mediated by reductions in sex hormone binding globulin (SHBG) and FT will go up marginally. Obesity can also suppress the hypothalamic-pituitary-gonadal axis (HPGA) leading to lowered TT and FT[1]. Poor diet and lifestyle choices including high stress and lack of sleep also contribute to low testosterone. TBI can disturb the communication between the hypothalamus and the pituitary. Male T levels normally fluctuate with a natural diurnal rhythm and are highest in the early morning and lowest right before bed. It is agreed that the diagnosis of low T can be made when TT is below 300 ng/dL on two separate morning blood draws. The production of T is driven by the HPGA. Gonadotropin releasing...
