Vacuum erection device in treatment of organic erectile dysfunction and penile vascular differences between patients with DM type I and DM type II.

The aim of this study is to investigate changes in the vascular system and hemodynamics between patients with organic erectile dysfunction (ED) (DM type I and II), as well as to compare the quality of sexual life between those two groups after the treatment with vacuum erection device (VED). Study enrolled 50 males with DM, aged from 35 to 67 years, who have attended the urologic clinic due to inability to attain and maintain an erection of the penis sufficient to permit satisfactory sexual intercourse. Patients were using VED and six months later were assessed for therapy results. The International Index of Erectile Function (IIEF) was used to quantify erectile dysfunction. Alprostadil injection test was also used, with Doppler color flow imaging system, to evaluate the peak systolic velocity (PSV) and diameter of cavernosal artery (DCA). Significantly higher values of PSV were obtained in patients with DM type II. Also, DCA showed significant difference between two groups of patients. There was significant improvement in three items of IIEF after six months of treatment among both groups of examinees. Patients with DM type I had more serious risk for development of arteriogenic ED. VED could be a good alternative therapy for patients who denied peroral therapy.

The therapeutic potential of royal jelly in benign prostatic hyperplasia. Comparison with contemporary literature.

The aim of this study is to establish the scientific benefit of royal jelly (RJ) on prostatic-specific antigen (PSA), post-void residual (PVR) volume and International Prostate Symptom Score (IPSS) in benign prostatic hyperplasia. For the study, a group of 40 men were administered 38 mg of RJ over a period of three months, their PSA values, prostate volumes and the volumes of their transitory prostate zones, PVR and IPPS values were measured at the end of the first month, and at the end of the third month. The results of this study confirm the potential of RJ in reducing PSA scores and improving IPSS values. Since the use of RJ did not lead to any significant reduction in PVR, prostate volume, or to any involution of the transitory zone, it appears that it may only affect the blood marker of prostatic hyperplasia and to improve quality-of-life (QoL) in those patients. Overall, in comparison to phytotherapy and conventional therapy, RJ had similar positive effects on QoL in patients with BPH, however it exhibited markedly better effects on reducing PSA levels in blood. The therapeutical use of RJ exhibited no side effects.

Comparison of Sperm Parameters in Patients with Infertility Induced by Genital Infection versus Varicocele.

BACKGROUND: Male infertility is a common and complex problem and, despite much research in this field, the major cause of infertility unfortunately remains unknown. Genital infection and varicocele are important causes of infertility. AIMS: To compare the influence of genital infection and varicocele individually on male infertility based on semen analysis. STUDY DESIGN: Cross-sectional study. METHODS: The study included 120 infertile patients divided into two groups according to the presence of genital infection or varicocele. The first group included 60 examinees with proven genital infection, but without varicocele formation. The second included 60 patients with varicocele, regardless of the varicocele grade, but without genital infection. The fertile parameters were compared and an assessment was performed on the impact on quality of spermatogenesis due to infection and varicocele. RESULTS: There is a statistically significant difference regarding abnormal forms of spermatozoids (45.94±9.79 vs. 25.27±6.54) and progressive motility (8.15±1.24 vs. 24.95±7.2), between two groups of patients. However, acidity of ejaculates, minimum sperm concentration, total spermatozoid motility and ejaculate volume showed no statistically significant difference. CONCLUSION: The study showed a stronger negative influence of genital infection on fertile parameters over varicocele. The significance of our study is the lack of contemporary researches comparing varicocele and genital infection influence on male infertility individually.

Correlation between nitric oxide levels, the hypo-osmotic swelling test for sperm membranes and semen analysis in patients with varicocele.

OBJECTIVE: Nitric oxide (NO) is a well-known oxidative stress agent that directly inhibits mitochondrial respiration and the synthesis of DNA. A case-control study of the concentration of NO in infertile patients with varicocele versus car-accident controls was performed. The concentration of NO in infertile patients with varicocele, and its correlation with the sperm fertility test named the hypo-osmotic swelling (HOS) test for sperm membranes and semen analysis, was also examined. MATERIAL AND METHODS: A spectrophotometric method was used to measure the concentration of NO in infertile subjects, and the HOS test was carried out according to Jeyendran's original protocol. NO values from left testicular vein and left cubital vein of 19 infertile patients with left-sided varicocele were compared to 15 patients in the control group who underwent explorative laparoscopies after car accidents. Semen analysis and the HOS test were performed only in the left-sided varicocele group and compared to the NO outcomes. RESULTS: The results indicate that the concentration of NO was significantly higher in the testicular vein than in the peripheral veins of patients with varicocele, as well as being significantly higher than in the testicular vein of control patients. An increased NO concentration in the testicular vein, higher sperm count and higher sperm motility in infertile patients with varicocele followed negative or suspicious findings of the HOS test for sperm membranes. There was also a significant correlation between NO concentration and sperm count in patients with varicocele. CONCLUSIONS: Further studies with more patients, related to NO concentrations and the HOS test are needed to verify these results.
