The stability of the function of the reproductive system depends on a multitude of factors of the internal and external milieux. Serious disturbances in its function, with alterations in carbohydrate homeostasis, underlie such diseases as diabetes mellitus. Disturbances to the functional activity of the reproductive system in laboratory animals with diabetes are known to be associated not only with destructive changes in the gonads, but also with dysfunction of the hypothalamo-hypophyseal complex [9, 11]. Published data show that these lesions have different severities in male and female individuals [7, 8]. The question of the extent to which lesions due to the diabetic state depend on the level of sex steroids and insulin in the body thus far remains unanswered. Unlike the situation in males, females are characterized by cyclic changes in the activity of the reproductive system. Thus, it is possible that differences in the regulation of gonadotropic function in male and female rats, observed in normal animals, could explain their different sensitivities to diabetes. Thus, we elected to carry out various studies of the functional activity of the hypothalamo-hypophyseal-gonadal system in male and female rats with experimental diabetes induced by administration of streptozotocin (STZ). |
