Background: Not only the most frequent causes of endocrine sexual dysfunction, such as hypogonadism and hyperprolactinemia, but almost all extragonadal endocrinopathies (hyper- and hypothyroidism, hyper- and hypocortisolism, steroidal secreting tumors, etc.) may have a greater or lesser effect on sexual function. Methods: We analyzed scientific literature on the correlations between hormones and sexual behavior, analyzing the most important issue from a practical point of view. The aim of this review article was thus to summarize the sexual symptoms that may be observed with endocrine diseases. Results: Hormones directly or indirectly regulate all human sexual functions (desire, erection/lubrication, ejaculation, orgasm). Some sexual symptoms may occur as a psychosomatic consequence of hormonal impairment. However, in other cases, endocrine failure may be generated by the psychosomatic involvement. Conclusions: The endocrinologist, as an expert in body chemistry, is ideally positioned to identify and evaluate the full range of medical, physical, and psychiatric problems disrupting sexual function.
