Abstract
PURPOSE The aim of this study was to evaluate in a population of patients with erectile dysfunction (ED): (a) the prevalence of a previously unknown endocrine/glycemic disorders; (b) the correlation between ED severity and endocrine/glycemic disorders. METHODS 1332 patients referred for ED from 2013 to 2020 were included. The ED diagnosis was made using the International-Erectile-Function-Index-5 questionnaire. ED severity was considered according to presence/absence of spontaneous erections, maintenance/achievement deficiency. All patients were subjected to search for sociodemographic and clinical characteristics: age, ethnicity, marital status, previous use of PDE5i, previous prostatectomy, diabetes mellitus (DM), prediabetes, endocrine dysfunctions. RESULTS The mean ± SD age was 54.3 ± 13.7 years. The 19.1% (255/1332) of patients were already in treatment for prediabetes/diabetes or endocrine dysfunctions. Among the remaining 1077, the prevalence of previously unknown endocrine and glycemic disorders was 30% (323/1077). Among them, 190/323 subjects (58.8%) were affected by hypogonadism, with high estradiol level observed in 8/190 (4.2%). The prevalence of new glycemic alterations was 17.3% (56/323) [specifically, 32/56 (57.1%) DM, and 24/56 (42.9%) prediabetes]. A thyroid dysfunction was observed in 40/323 subjects (12.3%) and hyperprolactinemia in 37/323 (11.5%). Patients with new diagnosis of DM showed more severe form of ED compared to the total group {difficulty in the achievement of erection: 46/56 [82.2%, vs 265/1332 (19.9%), p < 0.05]; absence of spontaneous erection 23/56 [41.1%, vs 321/1332 (24.1%), p < 0.05]}. CONCLUSION ED is an early marker of endocrine/glycemic disorder, and a previously unknown dysfunction was found in more than a quarter of patients. A newly diagnosed DM is associated with ED severity, especially in elderly man and in presence of hypertension.

Abstract
INTRODUCTION Erectile dysfunction (ED) is a common complication of Type-2 Diabetes Mellitus (T2DM) for male patients and it is considered to be associated with different causes including hyperglicemia-induced vascular endothelial cell damages. However, the possible central neural mechanisms shared by these two diseases remain unclear. This study aimed to explore the changes of brain activity and their relationships with the clinical characteristics in patients with diabetic ED. METHODS The data of resting-state functional magnetic resonance imaging were acquired in 31 T2DM patients with ED (DM-ED) and 31 matched healthy controls (HCs). The whole-brain regional homogeneity (ReHo) values were calculated and compared between groups. In addition, Pearson correlation analysis was performed to evaluate the relationships between brain regions with altered ReHo values and clinical characteristics in the patient group. RESULTS The DM-ED group exhibited increased ReHo values in the right middle frontal gyrus (orbital part) and decreased ReHo values in the left superior frontal gyrus (dorsolateral), paracentral lobule, precuneus and bilateral supplementary motor area when compared with the HCs group. Moreover, significantly negative correlations were found between ReHo values of the left superior frontal gyrus (dorsolateral) and IIEF-5 scores, as well as the level of HbA1c in the DM-ED group. CONCLUSION The altered spontaneous brain activity in cognitive-related regions revealed by ReHo values might provide new insights into the neurological pathophysiology underlying DM-ED and serve as potential neuroimaging biomarkers for detecting and evaluating ED in diabetes patients.

Abstract
BACKGROUND AND OBJECTIVES Stem cell therapy is a novel treatment with regenerative ability that can treat erectile dysfunction (ED). This phase 1/2 clinical trial (NCT02945449) using 2 consecutive intracavernous (IC) injections of allogeneic Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) was studied for the first time in the treatment of diabetic patients with ED. The primary outcome was to assess the safety and tolerability, and the secondary outcome was to assess the efficacy of 2 consecutive IC injections of allogeneic WJ-MSCs in diabetic ED. PATIENTS AND METHODS Twenty-two diabetic patients with refractory ED were included. Two consecutive IC injections of allogeneic WJ-MSCs were performed. Tolerability was assessed immediately, and at 24 h, safety was evaluated for 12 months. Efficacy was assessed using International Index of Erectile Function-5 (IIEF-5), Erection Hardness Score (EHS), and Color Duplex Doppler Ultrasound for 12 months. RESULTS The procedure was well-tolerated. Minimal and transient adverse events were redness and bruising at the site of injections. There were no patient-reported serious adverse effects. There were significant improvements in IIEF-5, EHS, peak systolic velocity (PSV) basal, and 20-min PSV, all over the follow-up time points in comparison to the baseline. CONCLUSION This is the first human study with proven tolerability, safety, and efficacy of IC injections of allogeneic WJ-MSCs for the treatment of diabetic patients with ED.

Abstract
Background Sexual function is often affected in patients suffering from chronic diseases especially chronic obstructive pulmonary disease (COPD). However, the effect of COPD on sexual satisfaction is underappreciated in clinical practice. The aim of this study is to evaluate the impact of COPD on patient’s sexuality and the explanatory variables of sexual dissatisfaction. Methods Questionnaires were emailed to participants and they submitted their responses on the Santé Respiratoire France website. Data about sexual well-being (Arizona Sexual Experience Scale, ASEX), Quality of life (VQ11), anxiety, depression (Hospitalized anxiety and depression, HAD) and self-declared COPD grade were collected. Results Seven hundred and fifty one subjects were included and were characterized as follows: women—51%, mean age—61 years, in a couple—62% and 70%—retired. Every grade of COPD was represented. Out of 751 participants, 301 participants (40%) had no sexual activity and 450 (60%) had sexual activity. From the 450 participants, 60% needed to change their sexual life because of their disease (rhythm, frequency and position). Subjects often used medications to improve sexual performance (43% used short-acting bronchodilator and 13% -specific erectile dysfunction drugs). ASEX questionnaire confirmed patients’ dissatisfaction (diminution of sexual appetite for 68% and sexual desire for 60%) because of breathlessness and fatigue. Eighty one percent of the responders had an altered quality of life (VQ11 mean score 35) and frequent suspected anxiety or depression (HAD mean score 10.8). Ninety percent declared that sexual dysfunction had never been discussed by their doctors, while 36% of patients would have preferred to undergo a specialized consultation. Conclusion Sexual dysfunction is frequent among COPD patients and leads to an altered well-being, however being a cultural taboo, it remains frequently neglected. Sexual guidance should be a part of patient’s consultations improve quality of sexual life.

Abstract
BACKGROUND This study aims to evaluate: 1) the prevalence of Female Sexual Dysfunction (FSD) in women affected by type 1 Diabetes Mellitus (DM) and the control group; 2) the correlation between duration of DM, HbA1C levels and sexual life quality; 3) the relationship between different methods of insulin administration and sexual life quality; 4) the correlation between FSD and diabetes complications. METHODS We selected 33 women with type 1 DM and 39 healthy women as controls. Each participant underwent a detailed medical history and physical examination and completed the 6-item Female Sexual Function Index questionnaire (FSFI-6). In patients affected by type 1 DM, the different methods of insulin administration (Multi Drug Injection - MDI or Continuous Subcutaneous Insulin Infusion - CSII) and the presence of DM complications were also investigated. RESULTS The prevalence of FSD (total score ≤ 19) was significantly higher in the type 1 DM group than in the control group (12/33, 36.4% and 2/39, 5.2%, respectively; p = 0.010). No statistically significant differences were found regarding FSD according to the presence of complications, method of insulin administration or previous pregnancies. CONCLUSIONS This study underlined that FSD is higher in women affected by type 1 DM than in healthy controls. This could be due to the diabetic neuropathy/angiopathy and the type of insulin administration. Therefore, it is important to investigate FSD in diabetic women, as well as erectile dysfunction in diabetic men.

Abstract
Objectives The extracts of Ferulago species are used as aphrodisiacs in Turkey and so we aimed to demonstrate in vivo and in vitro the relaxant effect of four Ferulago species' extracts on the corpus cavernosum (CC). Materials and Methods A total of 30 adult male Sprague Dawley rats were divided into control and diabetic groups. Diabetes was induced by a single intraperitoneal injection of 40 mg/kg streptozotocin. In vivo erectile responses were obtained by stimulation of the cavernosal nerves and repeated after intracavernosal injection of extracts in rats, and the data were expressed as intracavernosal pressure (ICP)/mean arterial pressure and total ICP. The relaxant and contractile responses of CC strips were analyzed in the presence or absence of extracts. Results The extracts were active in both control and diabetic rats. The extract-induced maximum relaxation responses (especially of methanol extract of the root of Ferulago bracteata) (98.30±2.6%) were decreased after incubation with L-NAME (44.8±1.8). ODQ, a soluble guanylate cyclase inhibitor, inhibited 77% of extract-induced maximum relaxation in the CC from the control rats. Conclusion These species can be utilized in erectile dysfunction and may be an herbal alternative to synthetic drugs.

Abstract
OBJECTIVE In diabetes mellitus, vitamin D3 deficiency affects sex hormone levels and male fertility; however, the mechanism leading to the disorder is unclear. This research was designed to investigate the mechanism of vitamin D3 deficiency and hypogonadism in diabetic rats. Our aim was to assess serum vitamin D3 levels and the relationship among vitamin D3, insulin-like growth factor-1 (IGF-1), and testicular function. MATERIALS AND METHODS Rats with streptozotocin-induced diabetes were randomly divided into four groups and treated with different doses of vitamin D3: no vitamin D3, low (0.025 μg/kg/day), high (0.1 μg/kg/day), and high (0.1 μg/kg/day) with JB-1 (the insulin-like growth factor-1 receptor inhibitor group, 100 μg/kg/day). The groups were compared with wild-type rats, which function as the control group. Various parameters such as vitamin D3 and IGF-1 were compared between the experimental and wild-type groups, and their correlations were determined. RESULTS Twelve weeks of vitamin D3 supplementation improved the testosterone levels, as shown by the increase in the level of serum IGF-1 in diabetic rats. Phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT), which was a downstream of the signaling pathway of IGF-1, was significantly increased after vitamin D3 treatment. CONCLUSIONS The study shows that vitamin D3 may promote the expression of testosterone and improve testicular function in diabetic rats by activating PI3K/AKT via IGF-1.

Abstract
OBJECTIVES To re-evaluate the role of diabetes mellitus (DM) as a risk factor for penile implant infection by exploring the association between glycated haemoglobin (HbA1c) levels and penile implant infection rates and to define a threshold value that predicts implant infection. PATIENTS AND METHODS We conducted a multicentre prospective study including all patients undergoing penile implant surgery between 2009 and 2015. Preoperative, perioperative and postoperative management were identical for the entire cohort. Univariate analysis was performed to define predictors of implant infection. The HbA1c levels were analysed as continuous variables and sequential analysis was conducted using 0.5% increments to define a threshold level predicting implant infection. Multivariable analysis was performed with the following factors entered in the model: DM, HbA1C level, patient age, implant type, number of vascular risk factors (VRFs), presence of Peyronie's disease (PD), body mass index (BMI), and surgeon volume. A receiver operating characteristic (ROC) curve was generated to define the optimal HbA1C threshold for infection prediction. RESULTS In all, 902 implant procedures were performed over the study period. The mean patient age was 56.6 years. The mean HbA1c level was 8.0%, with 81% of men having a HbA1c level of >6%. In all, 685 (76%) implants were malleable and 217 (24%) were inflatable devices; 302 (33.5%) patients also had a diagnosis of PD. The overall infection rate was 8.9% (80/902). Patients who had implant infection had significantly higher mean HbA1c levels, 9.5% vs 7.8% (P < 0.001). Grouping the cases by HbA1c level, we found infection rates were: 1.3% with HbA1c level of <6.5%, 1.5% for 6.5-7.5%, 6.5% for 7.6-8.5%, 14.7% for 8.6-9.5%, 22.4% for >9.5% (P < 0.001). Patient age, implant type, and number of VRFs were not predictive. Predictors defined on multivariable analysis were: PD, high BMI, and high HbA1c level, whilst a high-volume surgeon had a protective effect and was associated with a reduced infection risk. Using ROC analysis, we determined that a HbA1c threshold level of 8.5% predicted infection with a sensitivity of 80% and a specificity of 65%. CONCLUSION Uncontrolled DM is associated with increased risk of infection after penile implant surgery. The risk is directly related to the HbA1c level. A threshold HbA1c level of 8.5% is suggested for clinical use to identify patients at increased infection risk.

Abstract
Prescription sales of Testosterone and erectile aids such as phosphodiesterase-5 inhibitors are at an all-time high, underscoring the importance of hypogonadism (HG) and erectile dysfunction (ED) to men’s health. The effect of these debilitating conditions has a major impact on the quality of men’s lives. Some risk factors for HG or ED including aging, obesity, smoking, and a sedentary lifestyle. Notably, these are the same risk factors for several other medical co-morbidities that contribute to significant morbidity and mortality in men. HG and ED often co-exist with cardiovascular disease, diabetes, and osteoporosis. This review will explore these three co-morbidities that overlap with HG and ED, and will provide a review of their relationship with each other.
