Sexually transmitted diseases (STDs) are among the first ten causes of unpleasant diseases in young adult males in developing countries and the second major cause of unpleasant diseases in young adult women. Adolescents and young adults (15-24 years old) make up only 25% of the sexually active population, but represent almost 50% of all new acquired STDs. In general, STDs are epidemics and present an enormous health and economic consequences. An adequate screening for STDs should be done on a routine basis in every part of the world. Many STDs are asymptomatic and therefore can difficult to control. The purpose of reporting of STDs is to ensure that persons who are infected will be quickly diagnosed and appropriately treated to control the spread of infection and also so that partners are notified, tested and appropriately treated. It is estimated that reported cases of STDs represent only 50%-80% of reportable STD infections in the United States, reflecting limited screening and low disease reporting. High-risk sexual behavior is a highly contributive factor of this process as it often leads to teenage pregnancies and HIV/AIDS. One possible explanation for this behavior is that people do not have enough information about the transmission of STDs or ignore the precautions required for safe sex. Approximately 60% of new HIV infections worldwide occur in young people. The frequency of high-risk behaviors among youths may also be influenced by opportunity to engage in them, particularly the amount of time that they are unsupervised by adults. However, in diagnosing and treating these patients, we can effectively prevent the spread of HIV/AIDS. Individuals infected with STDs are 5-10 times more likely than uninfected individuals to acquire or transmit HIV through sexual contact. The breaking of the genital tract lining or skin creates a portal of entry for HIV and, hence, HIV-infected individuals with other STDs are more likely to shed HIV in their genital secretions. To date, the condom is the most effective method available for males for protection against STDs. It is important to control STDs, and prevention can be the key of this process. Prevention can be achieved through education of the population, identification of symptomatic and asymptomatic people, and effective diagnosis and treatment of these patients and their partners.

Purpose Metabolic syndrome is a risk factor for several diseases. The relationship between metabolic syndrome and hypogonadism is well known. Our objetive is to assess whether a low carbohydrate diet can increase total serum testosterone and improve erectile function in hypogonadal men with metabolic syndrome. Methods An open label randomized clinical trial was conducted comparing a low carbohydrate diet and controls, during three months, in hypogonadal men with metabolic syndrome. Anthropometric measurements were evaluated as well as total serum testosterone levels, and symptoms of hypogonadism, using the ADAM and AMS scores, and sexual function using IIEF-5 score. Results Eighteen men were evaluated. Anthropometric measures were improved only in low carbohydrate diet group. The intervention group also had a statistically increase in IIEF-5 score and a significant reduction in AMS and ADAM scores (p < 0.001). The increase in serum total testosterone levels was statistically significant in the low carbohydrate group compared to the control group as well as calculated free testosterone (p < 0.001). Conclusions Low carbohydrate diet may increase serum levels of testosterone and improve erectile function in hypogonadal men with metabolic syndrome. However, larger studies are necessary to strongly prove the effectiveness of low carbohydrate diet in treating male hypogonadism.

INTRODUCTION:Substantial controversy exists regarding the association between testosterone serum levels and prostate cancer.OBJECTIVE:To evaluate the levels of hypothalamic‐pituitary‐testicular axis hormones in the sera of men with prostate cancer and atypical small acinar proliferation as well as those with normal biopsies.METHODS:A study cohort of 186 men with suspected prostate cancer who had undergone transrectal prostate biopsies was used in this study. The patients were divided into the following three groups based on the histology of the biopsy samples: no neoplasia, atypical small acinar proliferation or prostate cancer. Demographic data were also collected. Levels of total testosterone, follicle‐stimulating hormone, luteinizing hormone, prolactin, estradiol, and serum prostate‐specific antigen were measured in blood samples.RESULTS:Initially, 123 men were found to be without neoplasia, 26 with atypical small acinar proliferation and 37 with prostate cancer. After a second biopsy was taken from the men diagnosed with atypical small acinar proliferation, the diagnoses were revised: 18 were diagnosed with atypical small acinar proliferation and 45 with prostate cancer. No significant differences between the groups were identified regarding age, smoking history, chronic diseases, body mass index or PSA levels (P>0.05). The mean serum levels of testosterone, follicle‐stimulating hormone, luteinizing hormone, prolactin and estradiol were similar in all of the groups (P>0.05). Furthermore, in individuals with prostate cancer, the Gleason scores and prevalence of hypogonadism were not significantly different (P>0.05).CONCLUSION:The present study revealed no difference in the serum levels of testosterone, follicle‐stimulating hormone, luteinizing hormone, prolactin or estradiol in men without neoplasia compared with those with atypical small acinar proliferation or prostate cancer.
