Sex hormones impact a number of aspects of immunity. As a result of the aging process, dramatic changes occur in the endocrine system, including the levels of sex hormones. Thus, it is possible that the hormonal environment may play a role in the effects
of normal body conditions are pituitary, thyroid, parathyroid, adrenal, pancreas, ovary, and testis. However, these organs are not the only tissues concerned in the hormonal regulation of body processes. For example, the duodenal mucosa, which is not organized as an endocrine gland, elaborates ...
