ED is extremely common in males with dysthyroidism. Treatment of the latter restores erectile function. Screening for thyroid dysfunction in men presenting with ED is recommended, whereas specific treatment for ED should be postponed in such patients for at least 6 months after achieving euthyroidism because the latter might be responsible for ED.

Hypothyroidism has an adverse effect on human spermatogenesis. Morphology is the only sperm parameter that is significantly affected. Motility may also be affected, but further studies regarding this are needed. Screening for thyroid dysfunction in males who present with a defect in spermatogenesis is strongly recommended, and if hypothyroidism is noted, the response to thyroid hormone should be evaluated before initiating other treatments.

Objective: The aim of this study was to investigate the incidence and long-term outcome of halitosis before and after eradication therapy in patients with functional dyspepsia and Helicobacter pylori infection. Subjects and Methods: Halitosis and dyspepsia-related symptoms were investigated by way of a questionnaire. Only patients with functional dyspepsia, H. pylori infection and no histological evidence of atrophy were included in the study. A total of 18 patients fulfilled these criteria and completed the study. Four to six weeks after the end of eradication treatment, endoscopy or [¹³C] breath test was performed to check for H. pylori in the gastric mucosa. Halitosis and dyspeptic symptoms were re-evaluated during and at the end of follow-up. Results:H. pylori infection was eradicated in all patients, in the 14/18 patients (77.8%) with triple drug therapy, and the 4/18 patients (22.2%) with quadruple drug therapy. During the follow-up period (mean 55.8 ± 21.3 months (range 6–108 months)) resolution of halitosis was observed in 16/18 patients (88.9%), while 2 patients (11.1%) (p < 0.001) continued to present with halitosis. Also, eradication therapy resulted in statistically significant relief of all dyspeptic symptoms, except bloating. Conclusion: Eradication of H. pylori in patients with functional dyspepsia and halitosis results in sustained resolution of halitosis during long-term follow-up in the majority of cases. This finding supports the existence of a link between H. pylori infection and halitosis and suggests that H. pylori eradication might be considered in patients with halitosis.
