Уважаемый Владимир,
Только специально для Вас я привожу первые попавшиеся мне в медлайне статьи последних 2-х лет, которые убедительно доказывают следующие положительные эффекты микрохирургической варикоцелэктомии:
1. Улучшение качества спермы
2. Увеличение количества беременностей у партнерш прооперированных больных
3. Улучшение продукции тестостерона
Последняя статья говорит о хороших отдаленных (6 лет) результатах. Так что сами или с помощью переводчика прочтите и сделайте выводы. Я как хирург, выполняющий подобные операции, могу своей практикой только подтвердить прекрасные результаты данного метода лечения варикоцеле.

The present study assesses the clinical outcome of microsurgical subinguinal varicocelectomy in infertile men, especially with regard to sperm count, motility and fertility. Between June 1990 and October 1998, 272 patients had subinguinal microsurgical varicocelectomy operations for clinical varicoceles, and their long-term results were assessed. In nearly all the patients there was a significant improvement in sperm count and sperm motility after 3 and 6 months. Very few complications arose from this procedure. We concluded that microsurgical subinguinal varicocelectomy is an effective treatment for clinical varicoceles in infertile men. The significant improvement in the quality of spermatozoa, the low complication rates and the remarkably high pregnancy rates make this a valuable alternative to in vitro reproduction techniques.Microsurgical varicocelectomy in the era of assisted reproductive technology: influence of initial semen quality on pregnancy rates.

OBJECTIVE: To evaluate the natural history of infertile couples in whom the man underwent varicocelectomy. DESIGN: Retrospective study. SETTING: University infertility clinic. PATIENT(S): 159 infertile couples. INTERVENTION(S): Microsurgical varicocelectomy. MAIN OUTCOME MEASURE(S): Standard semen parameters and pregnancy rates (assisted and unassisted). RESULT(S): Postoperative sperm concentration and motility increased significantly compared to before the varicocelectomy (28.9 +/- 3.0 vs. 22.5 +/- 2.1 x 10(6)/mL and 33.9 +/- 1.9 vs. 22.1 +/- 1.3%, respectively). Overall, 48% (76/159) of the couples achieved a spontaneous pregnancy at the mean of 30 months' follow-up. An additional 10% (16/159) and 11% (18/159) of couples achieved a pregnancy following intrauterine insemination and in vitro fertilization/intracytoplasmic sperm injection, respectively. Significantly higher spontaneous pregnancy rates were observed in couples in whom the man's initial sperm concentration was greater than or equal to 5 million sperm per milliliter compared to those in whom the man's initial sperm concentration was less than 5 million sperm per milliliter (61% vs. 8%, respectively). CONCLUSION(S): Our data demonstrate that, in couples in whom the man undergoes varicocelectomy for treatment of varicocele, close to 70% achieve a pregnancy. The initial sperm concentration is predictive of unassisted pregnancy outcome in this population.

OBJECTIVES: To analyse the effects of varicocelectomy on serum follicle-stimulating hormone (FSH), testosterone and free testosterone levels, and to investigate the interrelationships between seminal and hormonal variables. PATIENTS AND METHODS: The records were retrospectively evaluated for 78 infertile patients who underwent microsurgical inguinal varicocelectomy, with documented serum FSH, testosterone, free testosterone levels, sperm concentration and sperm motility before and after surgery. Left and bilateral varicoceles were detected in 40 and 38 patients, respectively. In addition, serum hormonal values of 10 fertile men in whom physical examinations and Doppler ultrasonography revealed no evidence of varicocele were recorded and used as a control group. RESULTS: The mean (sd) serum FSH levels of all patients decreased from 15.21 (3.34) before surgery to 10.82 (2.93) mIU/mL afterward (P=0.01), and serum testosterone levels increased from 5.63 (1.40) to 8.37 (2.2) ng/mL (P=0.01), whereas free testosterone levels increased from 23.13 (3.19) to 32.83 (4.37) pg/mL (P<0.001). In contrast to the significant difference in sperm motility before and after surgery of all patients (P<0.01), the difference in sperm count was insignificant (P>0.05). Thirty-six patients with high serum FSH levels before surgery had significantly lower levels afterward (P=0.001). In this group, the sperm concentration and motility also increased, from 17.66 (4.35) to 20.76 (4.37) million/mL (P=0.05) and from 30.9 (4.4)% to 37.5 (4.34)%, respectively (P=0.01). In the remaining 42 patients who had normal preoperative serum FSH levels, there was a slight decrease after surgery (P=0.02). Their sperm concentration increased slightly (P=0. 04), and motility also increased (P=0.001). Sixty patients had a significantly higher testosterone level after surgery; in this group the sperm concentration and motility increased (P=0.01). CONCLUSION: Varicocelectomy promotes Sertoli and Leydig cell function. The significant increase in serum free testosterone level results in a significant improvement in sperm concentration and motility.

BACKGROUND: Varicocele is found approximately in 15% of the male population and is considered a major cause of infertility. Varicocele management include surgical (traditional or laparoscopic) or conservative techniques (sclerotherapy). The authors present their experience on microsurgical inguinal varicocelectomy. This technique has been adopted since 1992 to decrease the incidence of recidives of high spermatic vein ligation; it also permitted to use local or loco-regional anesthesia, reducing time of hospitalization and realizing a minimally invasive approach. METHODS: From 1992 to 1997, 433 microsurgical inguinal varicocelectomy with artery and lymphatic sparing have been performed at the Militar Hospital of Milan in 409 young men with idiopathic varicocele. All patients were discharged 24 hours after operation. Only those who lived particularly far from the hospital remained for 48 hours. RESULTS: Clinical controls were performed I, III, VI months after operation. At the third control (VI month), a new semen analysis was performed, and 65% of patients had an improvement of seminal characteristics. In 394 patients, a complete resolution of varicocele was observed; 4 patients had a recurrence of the pathology and 11 had a recidive. Seventy-three patients who presented a concomitant homolateral inguinal hernia were treated at the same time. CONCLUSIONS: The conclusion is drawn that microsurgical ligation of spermatic veins represents a good surgical option in the treatment of varicocele. It is a quite simple technique that guarantees a low risk of recidives, permits using local or loco-regional anesthesia and can be performed in day-surgery with good results, few complications and good short and long term results.
