Abstract
OBJECTIVE The aim of this study is to evaluate the effect of avocado oil on the histoarchitecture of the prostate of normal rats and on rats with induced benign prostatic hyperplasia using computerized histomorphometry and immunohistochemistry. METHODS Twenty-eight Wistar rats were divided into four groups: the control group (CG), the avocado oil group (AOG) fed with avocado oil-based diet, the induced group (IG), and the avocado oil testosterone-induced group (AOIG). Prostate hyperplasia was induced by subcutaneous implantation of silicone pellets, filled with testosterone, to promote androgen stimulation. After 12 weeks, the rats were euthanized, and their prostates were removed. The material was prepared for paraffin processing and stained using hematoxylin-eosin and immunostaining for p63 nuclear antigen. RESULTS The mean epithelial thickness obtained from AOIG (19.44 ± 2.62 µm) was significantly reduced compared to that from IG (27.02 ± 4.1 µm). The average alveolar area in AOIG was 0.100 ± 0.03, which was greater than that of CG. The immunostaining for p63 in basal cells in AOIG was 17.77% ± 2.72 of the total area, a result greater than that in AOG (12.13% ± 2.04) and CG (12.01 ± 2.05). Collagen remodeling was observed with thicker fibers predominating in CG and AOG over thinner fibers in IG and AOIG. CONCLUSION The results suggest that avocado oil has a protective effect on the prostatic epithelium of Wistar rats subjected to long-term induced prostate hyperplasia.

Beneficial Effects of the Very-Low-Calorie Ketogenic Diet on the Symptoms of Male Accessory Gland Inflammation. Nutrients 2022; 14:nu14051081. [PMID: 35268056 PMCID: PMC8912840 DOI: 10.3390/nu14051081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 02/27/2022] [Accepted: 03/02/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction. Obesity exposes individuals to the risk of chronic inflammation of the prostate gland. Aim and design of the study. A longitudinal clinical study was conducted on selected overweight/obese patients with male accessory gland inflammation (MAGI) to evaluate the effects of body weight loss on their urogenital symptoms. Materials and methods. One hundred patients were selected and assigned to two groups undergoing two different nutritional programs. The first group (n = 50) started a Mediterranean diet (MedDiet) and the second (n = 50) a very-low-calorie ketogenic diet (VLCKD). Before and after three months on the diet, each patient was evaluated for body weight, waist circumference, and MAGI symptoms. The MAGI was assessed using the Structured Interview about MAGI (SI-MAGI), a questionnaire previously designed to assess the symptoms of MAGI. The questionnaire explores four domains, including urinary symptoms, ejaculatory pain or discomfort, sexual dysfunction, and impaired quality of life. Finally, in the two groups, the frequency of an α-blocker used to treat urinary tract symptoms was also evaluated. Results. Patients on MedDiet experienced significant amelioration in urinary symptoms and quality of life. Patients under VLCKD reported not only significant improvement of the same parameters, but also in ejaculatory pain/discomfort and sexual dysfunction. Finally, the percentage of patients on VLCKD taking the α-blocker decreased significantly. Moreover, patients under VLCKD showed a greater loss of body weight than those following the MedDiet. Discussion. The results of this study support the effectiveness of VLCKD in improving the symptoms of patients with MAGI. This improvement involved all of the domains of the SI-MAGI questionnaire and became manifest in a relatively short time. We suggest that a ketogenic nutritional approach can be used in overweight/obese patients with MAGI.

Abstract
Benign prostatic hyperplasia (BPH) is a common pathology among aging men. Despite the broad pharmacological interventions, the available remedies to treat BPH are yet not devoid of side effects. Herbal compounds are suggested to be an alternative option for the BPH treatment. In our study, we evaluated the effect of kudzu isoflavones and astaxanthin on the BPH animal model. The animals were randomly divided into five groups: control; testosterone-induced BPH group; and three BPH-induced groups, which received intragastrically for 28 days finasteride (5 mg/kg) as a positive control, isoflavones (200 mg/kg), and astaxanthin (25 mg/kg). BPH was induced by castration of animals and subsequent subcutaneous injections of prolonged testosterone (25 mg/kg). Prostate index and histology, biochemical parameters, and antioxidant activity were evaluated. A significant decrease in prostate weight, immunohistochemical markers, and normalization of prostate Ca/Mg ratio was found in all treatment groups. Astaxanthin treatment also resulted in decreased epithelial proliferation and normalized superoxide dismutase activity. In conclusion, both isoflavones and astaxanthin inhibited BPH development at a level comparable to finasteride in terms of prostate weight, prostatic epithelium proliferation, and prostate tissue cumulative histology score. These results suggest that isoflavones and especially astaxanthin could serve as a potential alternative therapy to treat BHP.

Relationship between Dietary Patterns with Benign Prostatic Hyperplasia and Erectile Dysfunction: A Collaborative Review. Nutrients 2021; 13:nu13114148. [PMID: 34836403 PMCID: PMC8618879 DOI: 10.3390/nu13114148] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Revised: 11/15/2021] [Accepted: 11/17/2021] [Indexed: 11/16/2022] Open
Abstract
Interest in the role of dietary patterns has been consistently emerging in recent years due to much research that has documented the impact of metabolism on erectile dysfunction (ED) and/or benign prostatic hyperplasia (BPH). We conducted a non-systematic review of English articles published from 1964 to September 2021. The search terms were: (“dietary patterns” OR “diet”) AND/OR (“erectile dysfunction”) AND/OR (“benign prostatic hyperplasia”). In the present review, we have highlighted how the association between dietary patterns and two of the most frequent pathologies in urology, namely erectile dysfunction and benign prostatic hyperplasia, is present in the literature. The data suggested that a diet that is more adherent to the Mediterranean diet or that emphasizes the presence of vegetables, fruits, nuts, legumes, and fish or other sources of long-chain (n-3) fats, in addition to reduced content of red meat, may have a beneficial role on erectile function. At the same time, the same beneficial effects can be transferred to BPH as a result of the indirect regulatory effects on prostatic growth and smooth muscle tone, thus determining an improvement in symptoms. Certainly, in-depth studies and translational medicine are needed to confirm these encouraging data.

Abstract
Introduction Introduction: indiscriminate use of anabolic steroids is associated with cardiovascular diseases, renal damage, and hepatic toxicity. Contrastingly, nutraceutical foods such as avocados prevent and control several diseases, as they can reduce the effects of oxidative stress. Objective: this study evaluates the benefits of consuming an avocado oil-based diet to attenuate the systemic damage caused by supraphysiological doses of testosterone, by analyzing the biochemical profile of 28 42-day-old male Wistar rats. Methods: silicone pellets containing testosterone were surgically implanted, and they received control or avocado oil-based feed. After 20 weeks, all the male rats were anesthetized and their blood samples collected. Results: although the high hormone concentration had a negative influence on the biochemical profile of these animals, the groups that consumed avocado oil exhibited a reduction in serum triacylglycerols (-21 %; p = 0.0001), VLDL (-20 %; p = 0.0085), LDL (-78 %; p < 0.0001), and total cholesterol (-12 %; p < 0.0001), along with positive changes in their HDL concentrations (+7 %; p = 0.001). The avocado oil groups also manifested a reduction in the total concentration of serum proteins (-24 %; p = 0.0357), albumin (-26 %; p = 0.0015), urea (-14 %; p = 0.04), and creatinine (-33 %; p < 0.0001). The concentration of liver transaminases was found to be higher in the animals included in the induced group (ALT, +66 %; p = 0.0005, and AST, +23 %; p = 0.0021), whereas they remained stable in the avocado oil group. Conclusion: from the above, it may be concluded that supraphysiological doses of testosterone are related to increased risk factors for cardiovascular, renal, and hepatic diseases, and that the consumption of avocado oil shields the biochemical profile, thus reducing the associated risk factors.

Abstract
In recent years, the progress of science and medicine greatly has influenced human life span and health. However, lifestyle habits, like physical activity, smoking cessation, moderate alcohol consumption, diet, and maintaining a normal body weight represent measures that greatly reduce the risk of various diseases. The type of diet is very important for disease development. Numerous epidemiological clinical data confirm that longevity is linked to predominantly plant-based diets and it is related to a long life; whereas the western diet, rich in red meat and fats, increases the risk of oxidative stress and thus the risk of developing various diseases and pre-aging. This review is focused on the bioavailability of polyphenols and the use of polyphenols for the prevention of prostate diseases. Special focus in this paper is placed on the isoflavonoids and flavan-3-ols, subgroups of polyphenols, and their protective effects against the development of prostate diseases.

Abstract
OBJECTIVE Benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) are common conditions that increase in the aging population. Several environmental factors have been linked to the development and progression of BPH and ED. Several studies have shown potential direct and indirect influences of several micronutrients and macronutrients on the risk of developing these conditions. We reviewed the available published literature of the effect of diet on BPH and ED. METHODS A comprehensive search was performed to identify studies that evaluated how diet affected males with BPH and ED. Searches were run on July 5th, 2018 in the following databases: Ovid MEDLINE®; Ovid EMBASE; and The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL). There were no language restrictions, publication date restrictions, or article type restrictions on the search strategy. RESULTS We retrieved a total of 1670 results across all databases. After removing any duplicated results, 2 independent reviewers screened a total of 1325 citations. A total of 35 articles were selected for inclusion in this review. Diet is an important factor affecting the risk of development of BPH and ED. Several studies have shown the effect of dietary interventions for BPH and ED. DISCUSSION A better understanding diet and its relative effects on the development, treatment and prevention of these diseases are an important area of further research for the given aging male population.
