Aim of this study is to evaluate the effects of micronised purified flavonoid fraction (Daflon(®)) on pain, semen analysis and color Doppler parameters in patients with painful varicocele. Forty varicocele patients whom have normal sperm concentration (>20 million/ml) were involved in the study. The patients were divided into two groups such as Daflon (n = 20) and placebo (n = 20) group. Pain score, semen analyses and Doppler sonography were performed in all patients before and after the treatment. In the first group, mean pain scores at 1, 3, 6 and 12 months were 1.80 ± 1.32, 1.15 ± 0.93, 1.05 ± 0.95 and 0.95 ± 0.89, respectively, all were significantly lower (P < 0.001 for each) than baseline (5.25 ± 1.07). While semen volume, total sperm count, sperm concentration and morphology were not changed significantly, the motility of sperm increased significantly (P = 0.015) due to decrease in grade 1 sperms at the 6th month in the first group. Reflux time of left spermatic vein during the Valsalva maneuver decreased significantly (P < 0.001). Results of this study suggest the safety and efficacy of Daflon in the treatment of varicocele-associated pain. However, these results of the present study must be confirmed by randomized placebo-controlled studies by using different drug doses and durations before making any recommendation for the use of Daflon.
  • [Show abstract] [Hide abstract] ABSTRACT: BACKGROUND: Between 30% to 80% of male subfertility cases are considered to be due to the damaging effects of oxidative stress on sperm and 1 man in 20 will be affected by subfertility. Antioxidants are widely available and inexpensive when compared to other fertility treatments and many men are already using these to improve their fertility. It is thought that oral supplementation with antioxidants may improve sperm quality by reducing oxidative stress. Pentoxifylline, a drug that acts like an antioxidant, was also included in this review.

  • [Show abstract] [Hide abstract] ABSTRACT: Varicoceles are a common finding in adolescent boys and men. Most are asymptomatic, although up to 10% may cause testicular pain. This study will review the use of varicocelectomy in the treatment of testicular pain in men with clinical varicoceles, as well as provide prognostic indicators for successful outcome. Recent studies that examined the impact of varix ligation on preoperative testicular pain were reviewed. Most studies are retrospective and uncontrolled; although objective outcome measures were used in the majority. Varicocele grade, duration of discomfort, and the quality of pain tended to predict outcome but have not been universally supported. On the basis of the majority of the recently published studies, varicocelectomy, in the properly chosen patients, results in significant improvement or resolution of testicular pain.

  • [Show abstract] [Hide abstract] ABSTRACT: Purpose: We investigated the effect of micronized purified flavonoid fraction on the prevention of testicular pathologies following varicocele induction. Materials and methods: A total of 66 adolescent (6-week-old) male Wistar rats were included in study. Rats were divided into 7 groups, including group 1--control, group 2--sham operation, group 3--left varicocele induced, group 4--varicocele induced, varicocelectomy done 4 weeks later and micronized purified flavonoid fraction administered for 4 weeks, group 5--varicocele induced and micronized purified flavonoid fraction administered for 8 weeks, group 6--varicocele induced and beginning 4 weeks later micronized purified flavonoid fraction administered for 4 weeks, and group 7--varicocele induced and varicocelectomy done 4 weeks later. Before sacrifice bilateral real-time testicular microvascular perfusion of all rats was measured using the PeriFlux System 5000 PF 5010 LDPM Unit (Perimed, Järfälla, Sweden). All testes were graded according to the Johnsen scoring system. To assess apoptosis caspase-3 levels were measured. Results: Testicular weight in group 3 was markedly decreased and the extent of seminiferous tubular damage was significantly increased compared with the other groups. Bilateral testicular blood flow and the number of apoptotic germ cells were greater in group 3. Significantly higher Johnsen scores and a meaningful decrease in the apoptotic index were detected in groups 4 to 7 compared with group 3. Conclusions: We observed favorable effects of micronized purified flavonoid fraction on the regression of testicular damage secondary to varicocele.
