Abstract
Premature ejaculation (PE) is the most common male sexual dysfunction, with 30% of men experiencing PE worldwide. According to the generally accepted classification, there are two types of PE: lifetime PE and acquired PE. Various biological and psychological causes are known to be involved in the etiology of PE. However, due to the incomplete definition and etiopathogenesis of PE, there is no effective treatment. Although clinical and animal studies indicate that hormones play a role in controlling the ejaculation process, the precise endocrine mechanisms are unclear. In addition, little is known about the role of endocrine disorders in PE etiology. However, there is evidence that diabetes mellitus (DM), obesity, metabolic syndrome (MetS), thyroid gland disorders, pituitary gland disorders, and vitamin D deficiency affect the prevalence of PE. Moreover, it has been reported that the prevalence of PE decreases with treatment of these endocrine disorders. In this review, the relationship between PE and DM, MetS, obesity, vitamin D deficiency, and thyroid and pituitary gland disorders is summarized.

Abstract
INTRODUCTION The interplay between erectile dysfunction (ED) and premature ejaculation (PE) needs more studies to clarify. AIM To evaluate the risk factors and temporal relationship for the coexistence of ED and PE. METHODS The data were derived from clinical history. MAIN OUTCOME MEASURE The diagnosis of ED and PE was based on self-report and validated questionnaires. RESULTS Based on the chief complaint, 1,893 participants were recruited as ED group and 483 participants as PE group from 2014 to 2020. One third of ED and PE groups reported comorbid PE and ED. Of the ED group, 4.1% (n = 77) had lifelong PE, 18.0% (n = 341) had acquired PE and 9.7% (n = 184) had subjective or natural variable PE. Of the PE group, ED was reported in 22.0% (n = 40) of lifelong PE, 33.9% (n = 65) of acquired PE, and 37.6% (n = 41) of subjective or natural variable PE, P < .01. With adjustment of potential confounders, the ED severity was associated with increased risk of acquired PE, while acquired PE was associated with higher risk of ED than lifelong PE. In cases of comorbid lifelong PE and ED (n = 117), 22.2% reported the onset of both dysfunctions being about the same time, whereas 77.8% reported ED occurred behind PE with an average 23.3 years lag. In cases of comorbid acquired PE and ED (n = 406), 52.2% reported the onset of both dysfunctions being about the same time, 34.2% reported ED happened behind PE and 13.5% reported PE emerged behind ED. CONCLUSION Organic pathogenesis was least likely to be responsible for the link between PE and ED. When acquired PE and ED coexist, treating ED first or concomitantly according to their temporal order is an appropriate management algorithm. Chieh‑Wen Chin, Chia Mu Tsai, Jen-Tai Lin, et al.

ENVIRONMENTAL EPIGENETICS 2020; 6:dvaa019.

Abstract
The most prevalent diseases worldwide are non-communicable such as obesity and type 2 diabetes. Noteworthy, the prevalence of obesity and type 2 diabetes is expected to steadily increase in the next decades, mostly fueled by bad feeding habits, stress, and sedentarism. The reproductive function of individuals is severely affected by abnormal metabolic environments, both at mechanical and biochemical levels. Along with mechanical dysfunctions, and decreased sperm quality (promoted both directly and indirectly by metabolic abnormalities), several studies have already reported the potentially harmful effects of metabolic disorders in the genetic and epigenetic cargo of spermatozoa, and the epigenetic inheritance of molecular signatures induced by metabolic profile (paternal diet, obesity, and diabetes). The inheritance of epigenetic factors towards the development of metabolic abnormalities means that more people in reproductive age can potentially suffer from these disorders and for longer periods. In its turn, these individuals can also transmit this (epi)genetic information to future generations, creating a vicious cycle. In this review, we collect the reported harmful effects related to acquired metabolic disorders and diet in sperm parameters and male reproductive potential. Besides, we will discuss the novel findings regarding paternal epigenetic inheritance, particularly the ones induced by paternal diet rich in fats, obesity, and type 2 diabetes. We analyze the data attained with in vitro and animal models as well as in long-term transgenerational population studies. Although the findings on this topic are very recent, epigenetic inheritance of metabolic disease has a huge societal impact, which may be crucial to tackle the 'fat epidemic' efficiently.

Abstract
OBJECTIVE Visceral adiposity index (VAI) is a novel indicator for the assessment of visceral obesity. In this study, we aimed to evaluate the relationship between VAI and premature ejaculation (PE). MATERIALS AND METHOD A total of 300 men were included in the study. Hundred and fifty men with PE and 150 men without PE (control). All men were evaluated for PE by premature ejaculation diagnostic tool (PEDT). VAI levels were calculated using body mass index (BMI), high density lipoprotein and triglyceride (TG) levels. RESULTS Mean age of the study groups was 34.3 ± 5.2 (30-60) years and the mean age of the controls were 35.9 ± 5.3 (30-60) years. The men with PE had lower BMI, TG levels, waist circumference (WC) and higher high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 4.13 ± 0.7 in study group and 5.72 ± 1.6 in control group, respectively. VAI levels were statistically higher in men without PE (p < .001). DISCUSSION Our cross-sectional study demonstrated a negative correlation between VAI and PE. VAI is superior index for the evaluation and calculation the relationship between obesity and PE.

Abstract
This prospective study aimed to investigate the relationship between metabolic syndrome (Met S) and premature ejaculation (PE) among men. The study included 300 consecutive male patients (53.6 y ± 8.7) who attended the urology clinic (December 2013-September 2014), mostly complaining of renal/ureteric calculi. A diagnostic approach was undertaken to include demographics, clinical features and laboratory investigations of the study subjects. Both erectile function and PE were evaluated using the International Index of Erectile Function (abridged form, IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires, respectively. Results identified 182 (60.7%) men had Met S. Prevalence of PE was significantly higher in the subjects with Met S than the controls (35.2% vs 7.6%, p < 0.001). Patients with Met S and PE had significantly higher PEDT scores (15.4 vs 6.7), smaller waist circumference (108.3 cm vs 111.5 cm) and higher fasting blood sugar (187 mg% vs 161 mg%) than those with no PE (p < 0.001, 0.047 and 0.019, respectively). The other variables including IIEF-5 score, body mass index, serum triglycerides and high-density lipoprotein (14.98 vs 16.8, 30.6 vs 31.5, 192.9 mg% vs 178.1 mg% and 37.4 mg% vs 36.2 mg%, respectively) did not reveal significant differences. Both systolic hypertension and erectile dysfunction (ED) had significant associations (p = 0.047 and <0.001, respectively) with PE in Met S. In conclusion, PE has a high prevalence in Met S. Patients with Met S should be questioned about PE. Both ED and systolic hypertension may be associated with PE. Prevention of Met S should be considered, and this may be of help to decrease the prevalence of PE.

Abstract
There are no interventional studies on the impact of sexual distress (SD) in men with obesity. We investigated the effects of vardenafil (VAR) on SD in middle-aged (mean age 49 ± 8), healthy, obese men in the absence of premature ejaculation, ED or hypogonadism. After a 4-week run-in period, 20 men with high body mass index (BMI=40 ± 8) and SD at the Sexual Distress Esteem Questionnaire-Male (mean score 65 ± 20 AU) were randomized to receive either VAR 10 mg on demand (N=10) or matched-placebo (PLB, N=10). Primary endpoints were variations from baseline in the intravaginal ejaculatory latency time (IELT) measured by the stopwatch technique; secondary endpoints were variations from baseline in Self-Esteem and Relationship (SEAR) and Male Sexual Health Questionnaire-Ejaculatory domain (MSHQ-EjD) scores. VAR significantly improved IELT (P<0.0001), as well as SEAR (P<0.001) and MSHQ-EjD (P<0.005) scores, whereas no changes were observed after PLB. Interestingly, an inverse relationship between BMI and IELT was found in all the men studied (r(2)=0.37, P<0.001). SD in healthy obese men seems to be correlated mainly with inadequate ejaculatory control, especially in men with higher BMI. Our preliminary results suggest that treatment with VAR may improve ejaculatory control, thus ameliorating self-esteem and sexual performance in men with obesity.
