  • efficacy of varicocele embolization versus ligation of the left internal Spermatic Vein for improvement of sperm quality
    International Journal of Andrology, 1992
    Co-Authors: Haim Yavetz, R Levy, J Papo, Leah Yogev, G Paz, Ariel J Jaffa, Z T Homonnai
    Abstract:

    Summary Efficacy of surgical varicocelectomy versus embolization of the Spermatic Vein was studied in 137 men diagnosed as suffering from left varicocele. The men were divided randomly into three groups according to the methods of treatment: A -embolization of the internal Spermatic Vein (51 men); B - Ivanissevich technique of high ligation of the Spermatic Veins (43 men); and C - Bernardi technique of high ligation (43 men). The groups were similar in terms of age, duration of infertility and possessed semen characterized as oligoteratoasthenozoospermia. The fertility of the female partners was evaluated carefully and they were found to be potentially fertile. Varicocele was diagnosed by at least two of the following methods: physical palpation during valsalva manoeuvre, venography, or scrotal scanning using the technetium pertechnate radioactive method. Semen quality was assessed before treatment and at 3, 6 and 9 months post-treatment. Fecundity was followed-up for 18 months. The major results were: (i). Shrinkage of the varicocele was found in all three groups studied. The same rate of recurrence was recorded in the three groups (24%, 37% and 35% in groups A, B and C, respectively). (ii). Improvement of sperm quality was significant in groups A and B, with better results in group B. (iii). The pregnancy rate was significantly higher in group B, compared with A (38.2% vs. 20.6%; P <0.05). Thus, high ligation of the internal Spermatic Vein yields better results than low ligation or embolization as far as semen quality and pregnancy is concerned.

  • Inhibin B and Anti-Müllerian Hormone in Spermatic Vein of Subfertile Men With Varicocele:
    Reproductive Sciences, 2011
    Co-Authors: Gesthimani Mintziori, Nikolaos Koliakos, Dimitrios Hatzichristou, Ioannis Papadimas, Konstantinos Hatzimouratidis, Dimitrios Goulis
    Abstract:

    Introduction: The pathophysiology of subfertility in men with varicocele remains unclear as well as the role of inhibin B (Inh-B) and anti-Mullerian hormone (AMH). The aim of this study was to evaluate Inh-B and AMH concentrations in the Spermatic Vein of subfertile men with varicocele. Patients and Methods: A total of 61 subfertile men with varicocele and 31 fertile controls underwent standard andrological evaluation. All subfertile men underwent varicocelectomy, during which blood samples were obtained from the Spermatic Vein to evaluate Inh-B and AMH concentrations. Results: Peripheral Vein Inh-B concentrations in men with varicocele were lower as compared to controls (52.9 [8.3-136.0) vs 116±9.7 ng/dL, P = .001). There was no difference in AMH concentrations (10.2 [4.4-45.4]) vs 10.4±0.8 pg/dL, P = 0.9). Spermatic Vein Inh-B concentrations in men with varicocele were higher compared to those of peripheral Vein (87.6±4.4 vs 52.9 [8.3-136.0] ng/dL, P = .001). On the contrary, Spermatic Vein AMH concentr...

  • a proposed anatomic typing of the right internal Spermatic Vein importance for percutaneous sclerotherapy of varicocele
    CardioVascular and Interventional Radiology, 2006
    Co-Authors: Yoel Siegel, Yigal Gat, Gil N Bacher, Michael Gornish
    Abstract:

    To classify the anatomic types of the right internal Spermatic Vein (ISV). We evaluated venograms obtained in 150 consecutive patients with idiopathic varicocele referred for transfemoral sclerotherapy. Six anatomic types of the right internal Spermatic Vein (ISV) were recognized. These were classified by the location of their orifices and the tributary venous patterns. In roughly half the patients (53%), the ISV appeared as a simple Vein with no remarkable retroperitoneal interconnections. In the remainder, complex retroperitoneal anastomoses were encountered. By understanding these anatomic variations, the angiographer can approach treatment of right-sided varicocele with foreknowledge of the nature of these types and the presence of valves and collaterals.
