“…In terms of the laterality of varicocele, 79.7% of patients were left‐sided, while the others were bilateral. This is compatible with earlier reports claiming that right‐sided varicocele is extremely rare and the incidence of bilateral varicocele is 2.5–65% depending on the modality of diagnosis 2 …”

“…In the present study, varicocele was observed in 16.5% of the patients admitted to our hospital complaining of infertility. This figure seems to be slightly smaller than in previous reports 2 . In the present study, screening of varicocele was conducted by palpation, not ultrasound or venography, because the clinical importance of subclinical varicocele is yet to be fully elucidated, which may explain the relatively smaller percentage of varicocele patients.…”

“…Many studies have demonstrated data regarding the etiology and pathophysiologies of varicocele, and its influence on spermatogenesis and the reproductive hormonal axis 1 . However, many questions still remain to be resolved, such as the extent that varicocele affects the male reproductive system, the mechanics by which the male reproductive system is affected, the most appropriate diagnostic modalities of varicocele and the efficacy and indication of surgical intervention against varicocele 1,2,4 . Moreover, only some of the reports refer to the pregnancy rate after a long period of follow‐up 5,6 …”

Background : The results of clinical examinations of varicocele and the clinical outcome of varicocelectomy conducted at Tsukuba University Hospital, Tsukuba City, Japan were analyzed. Methods : The subjects of the present study were sixty-four infertile male patients with varicocele who visited our hospital from 1991 to 1999. A physical examination, semen analysis and hormonal evaluation were performed for each patient. Patients selected their preferred type of treatment (varicocelectomy or conservative treatment) after providing their informed consent.Results : The age of the patients was 34.1 ± 5.1 (mean ± standard deviation [s.d.]) years, and the infertile duration was 4.2 ± 3.0 (mean ± s.d.) years. Fifty-one cases were left-sided; 13 were bilateral. Mean sperm density ( ¥ 10 6 /mL) was 37.2 for Grade I, 21.3 for Grade II and 9.4 for Grade III. Sperm density was significantly lower in the higher-graded patients ( P = 0.008). Varicocelectomy was performed in 31 cases; the postoperative/preoperative ratio of sperm density was significantly higher in the higher-graded varicocele ( P = 0.04), and the peak/base ratio of follicle-stimulating hormone (FSH) after luteinizing hormone-releasing hormone (LH-RH) stimulation was significantly decreased after varicocelectomy ( P = 0.007). The pregnancy rate in the partners of the varicocelectomized group (60%) was significantly higher than in the conservatively treated group (28%) P = 0.04; the mean follow-up duration was 76.2 months. Conclusion : These results show that varicocele should influence spermatogenesis, therefore altered spermatogenesis could be effectively treated by varicocelectomy, and varicocelectomy should induce a higher probability of pregnancy.
