The proper function of erection mechanisms depend on correct interrelationship between psychological, vascular, neurological and hormonal factors. Endocrine diseases affect sexual function, and sexual dysfunction may be one of the symptoms of some hormonal anomalies. Diabetes mellitus is the endocrine disease most frequently causing erectile dysfunction due to the frequent vascular and neurological complications associated. It is important to determine blood glucose in the initial evaluation of a male with erectile dysfunction, as well as to try an adequate control of blood glucose levels to avoid worsening...

Erectile dysfunction (ED) is the most common sexual problem in men. The incidence increases with age and affects up to one third of men throughout their lives. It causes a substantial negative impact on intimate relationships, quality of life, and self-esteem. History and physical examination are sufficient to make a diagnosis of ED in most cases, because there is no preferred, first-line diagnostic test. Initial diagnostic workup should usually be limited to a fasting serum glucose level and lipid panel, thyroid-stimulating hormone test, and morning total testosterone level...

INTRODUCTION: Erectile dysfunction (ED) is frequent in males with chronic heart failure (HF) with a severe impact on quality of life for many individuals. The correlation of ED with age and HF severity, comorbidity, and treatment is unclear. AIM: We evaluated the correlation between ED and HF severity, treatment, and comorbidity. METHODS: One hundred one HF patients aged < or =70 years, with left ventricular ejection fraction < or =40%, and stable clinical condition took part in the study...

INTRODUCTION: Female sexual dysfunction (FSD) is characterized by reduced sexual appetite and altered psychologic and physiologic response to sexual intercourse; it is reported to be frequent in diabetes mellitus, but no data have been reported in thyroid disorders. AIMS: To compare the prevalence of FSD in diabetic, in obese, and in hypothyroid women vs. healthy women, and to correlate FSD with endocrine and metabolic profiles. METHODS: We evaluated, through a questionnaire (Female Sexual Function Index [FSFI]), the prevalence of FSD in 91 women affected by diabetes mellitus, obesity, or hypothyroidism, and in 36 healthy women, all aged 22-51 years and in premenopausal state...

AIMS: To evaluate the cause of failure of sildenafil citrate (Viagra) to restore erections in patients with organic erectile dysfunction (ED) associated with type II diabetes mellitus (DM) and receiving oral antidiabetic drugs. METHODS: Diabetic ED patients (n = 120), aged 43-74 years, failing to respond at least three times to 100 mg Viagra were evaluated. After at least 2 weeks' treatment with oral testosterone undecanoate (Andriol), 100 mg Viagra was used before coitus...

The high-affinity binding of the sex hormone-binding globulin (SHBG) for testosterone and to a lesser extent for estradiol influences the circulating levels of these sex steroid hormones, their biodisposal to target cells as well as their mutual balance. Although the regulation of SHBG is still not completely understood, in vitro studies performed with human hepatocarcinoma (Hep G2) cells have shown that estrogens and thyroxine stimulate SHBG secretion, by increasing the steady state of its mRNA concentrations...

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...
