Testicular dysfunction in men with primary hypothyroidism; reversal of hypogonadotrophic hypogonadism with replacement thyroxine
OBJECTIVE Primary hypothyroidism can cause disturbances in normal gonadal function. The aim of this study was to investigate the relationship in men between hypogonadism and primary hypothyroidism and the extent to which free and total testosterone levels rose after introduction of replacement thyroxine.
DISCUSSION We conclude that primary hypothyroidism can induce a state of hypogonadotrophic hypogonadism in men that is reversible with thyroxine replacement therapy. A derangement of gonadotrophin secretion must be present and could be due to either a direct effect of hypothyroidism on the hypothalamus or pituitary, or mediated by perturbations of prolactin levels. Importantly, some of the clinical manifestations of primary hypothyroidism in men may be due in part to a reduction in free testosterone. Further evaluation of this potential clinical interaction would require a controlled trial of androgen replacement in the hypothyroid state. However, the data support the resolution of hypogonadotrophic hypogonadism with thyroxine replacement and restoration of normal thyroid function.
If you still don't feel well, look into hypothyroidism. Maybe it's the last piece of the puzzle.
