[The function of the hypophysis-gonadal system in men with diabetes and in men with thyroid diseases].

A study was made of indices of the hypophyseogonadal system in men with diabetes mellitus, in men with autoimmune thyroiditis and hypothyroidism, and in men with Basedow's disease. Sexual dysfunction was detected in 51% of patients with diabetes mellitus and in 78.5% patients with hypothyroidism. A high level of serum prolactin in these patients resulted in a decrease in the sensitivity of testicles to LH, causing a decrease in testicular androgenic function. It was confirmed by a low blood level of T and a decreased response of the gonads to CG administration. Patients with hypothyroidism demonstrated a decrease in the blood level of LH and TSH causing testicular dysfunction. An increased level of LH and T was found in patients with Basedow's disease. The absence of an adequate rise of the blood concentration of T in response to CG administration in this group of patients can be attributed to the fact that in Basedow's disease the hypophyseogonadal system functions under great strain.
