Original Study


Objectives This study aims to evaluate the outcome of varicocelectomy on the hormonal and spermatogenic function of the testis. Background Varicocele of the testis is the most common male factor causing subfertility. The harmful effect of varicocele on the testis has been documented, and the value of varicocelectomy in improving spermatogenesis has also been confirmed. However, the effect of varicocele on steroidogenesis and the role of varicocelectomy in improving testicular testosterone production are still under evaluation. Patients and methods This prospective study included 46 patients with bilateral varicocele. Semen analysis was carried out and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone were obtained preoperatively. Bilateral inguinal varicocelectomy was performed in all 46 patients. All patients were followed up 3 months postoperatively by semen analysis and serum levels of FSH, LH, and testosterone. Only 32 patients were followed up 6 months postoperatively, also by semen analysis and serum levels of FSH, LH, and testosterone. Results There was no statistically significant change in the levels of FSH, LH, and testosterone postoperatively even after 6 months of follow-up. However, a significant increase in the testosterone level was found in patients with preoperative low testosterone level (≥3 ng/ml) both at 3 months (P = 0.005 ) and at 6 months (P = 0.004) from the operation. Both sperm concentration and progressive sperm motility showed statistically significant increases both at 3 months (P = 0.0003 and 0.0001, respectively) and 6 months (P = 0.0001 and 0.002, respectively) of follow-up. Normal morphology of sperm showed a statistically significant improvement only after 3 months of follow-up (P = 0.008). Conclusion Varicocelectomy improves the spermatogenic function of the testis. In addition, it has a favorable effect on testosterone production in patients with varicocele and low serum testosterone.
