Abstract Background Varicocele is defined as abnormal dilation and tourtousity of the internal spermatic veins within the pampiniform plexus. It is common among adolescents and may contribute significantly to the risk of subfertility in adulthood. Objective To evaluate the outcome of extended varicocelectomy in case of high grade varicocele. Patients and methods In all, 30 varicocele cases including 12 left sided and 18 bilateral, comprising 48 spermatic cord units with clinically palpable varicocele and affected semen analysis underwent extended varicocele ligation. Testicular delivery was done in all the cases and assessment of the gubernacular veins was reported. The patients underwent clinical evaluation, scrotal doppler ultrasonography, as well as semen analysis to detect varicocele recurrence, hydrocele formation and early changes in semen parameters. The postoperative evaluation period was 3 months. Results No varicocele recurrences were clinically detectable after our surgical approach, No hydrocele formation, and There was improvement in the parameters of semen analysis in the entire patients presented with infertility associated with varicocele as regard improvement in the count, motility, and decrease in the abnormal forms 3 months after varicocelectomy. Conclusion Extended varicocele ligation with delivery of the testis achieve good surgical outcome with minimal varicocele recurrence and hydrocele formation, and offer beneficial effect on semen parameters.

Varicocele is a disease characterized by an abnormal dilation of the pampiniform plexus that drains the testis. The main objective of this work was to evaluate the curative effects of aqueous and ethanolic extracts of Dracaena arborea on some reproductive and antioxidant markers in rats with experimental varicocele. Following varicocele induction, rats (5 per group) were randomly partitioned into untreated varicocele, vitamin E-treated (150 mg/kg), aqueous extract-treated (500 mg/kg), and ethanolic extract-treated (100 mg/kg) animals. Two other groups served as normal and sham-operated. After 2 or 4 weeks of treatments, body and sex organ weights, spermatozoa characteristics, antioxidant status, NO level, sex hormones, and testis histology were measured. Animals with 3 weeks of varicocele showed a significant ( p  < 0.05–0.001) decrease in body and sex organ weights, total proteins, sperm characteristics, testosterone concentration, SOD, catalase, and total peroxidase activities. An increase in the plasmatic FSH, LH, and testicular MDA and NO concentrations was also recorded. Moreover, marked disorganization of the testicular architecture was observed. Treatment with D. arborea significantly reversed these impairments due to varicocele. For instance, after 4 weeks, treatment with aqueous extract of D. arborea significantly ( p  < 0.05–0.001) increased testes and epididymis weights, sperm viability (89.12 ± 1.09 vs 68.22 ± 1.42), sperm density (148.50 ± 2.59 vs 110.25 ± 2.51), and sperm motility (68.16 ± 2.39 vs 55.88 ± 3.20) in the left side, compared with varicocele-untreated rats. The extract also significantly ( p  < 0.05–0.001) decreased malondialdehyde level (2.19 ± 0.04 vs 3.50 ± 0.13) but elevated catalase (0.97 ± 0.03 vs 0.55 ± 0.03), SOD (0.5 ± 0.03 vs 0.15 ± 0.03), and peroxidase (65.80 ± 2.9 vs 40.95 ± 2.44) activities. Present results showed that D. arborea extracts possess antioxidant effects and improve sperm quality in male rats with an existing varicocele.

Varicocele is defined as an abnormal dilatation of the pampiniform plexus of the spermatic cord. This is seen in 10 to 20% of general population and is one of the most common correctable causes of male infertility. The history of varicocele dates back to the era of Ancient Greeks to about 600 BC, who had sculptured varicocele in their statues as a tortuous bag of wormsin the scrotum. It was Ambrose Pare who gave a poetic description to the pooling of blood in the spermatic cords and subsequently Curling coined the term Varicocele The intricacy of the venous drainage of the scrotum and its contents and the criss crossing of the veins makes the thermo-regulatory mechanism regulating spermatogenesis, even more complex. The Cremaster and Dartos greatly aid in facilitating the thermo-regulatory mechanism of scrotal wall, which forms the anatomical basis of oligospermia in patients with varicocele. Apart from a visible change in seminal parameters, the benefits of varicocelectomy have extended on to an improvement in serum testosterone and enhancement of erectile and ejaculatory functions. With a greater knowledge of the pathophysiology of varicocele and with better understanding of the roles of gene polymorphisms and reactive oxygen species, the indications for varicocelectomy gain more support and evidence. A sound anatomical knowledge and an in-depth understanding of the events that take place at molecular level might shift the treatment focus in future from varicocelectomy to molecular targeted therapies.

AbstractThe purpose of this study was to curate clustered findings of duplex ultrasound in the evaluation of spermatic venous varicoceles, and deliver more responses to the present concerns. Archives of 979 men who had undergone scrotum and spermatic venous plexus duplex ultrasound were reviewed. In the duplex ultrasound interrogation, the sizes of the larger vessels of the spermatic venous plexus, peritesticular vessels, and testicular volume and relevant parameters were measured. Findings of the vessels were analyzed. One hundred and eight-one out of 979 patients had varicoceles. Color Doppler flow signal was rendered in veins of pampiniform plexus but not in peritesticular vessels in 501 out of 979 patients; 101 out of 501 patients had veins of pampiniform plexus ≤ 3 mm, no color Doppler flow signal could be rendered in the veins in the 101 patients at supine and standing positions without Valsalva maneuver, color Doppler flow signal could be rendered in the veins in 82 out of 101 patients at supine and standing positions with Valsalva maneuver; no color Doppler flow signal could be rendered in the veins from 19 out of 101 patients with and without Valsalva maneuver at supine and standing positions. 37 out of 979 patients with 61 ipsilateral testicular volume ≤ 5 mL had no vessel diameter > 2 mm. The incidences of varicoceles corresponding to different ranges of testicular volume of 1–5 mL, 5.1–10 mL, 10.1–15 mL, 15.1–20 mL, 20.1–25 mL, and 25.1–30 mL were 0.0%, 6.9%, 8.3%, 6.63%, 20.94%, and 59.1%, respectively. The comparisons of incidences of varicocele between distribution percentages of different ranges of testicular volume of 1–5 mL and others (of 5.1 mL and more) were all significant (all P < 0.05). The correlation coefficient between the different ranges of testicular volume and the incidence of varicoceles was 0.829. Increased testicular volume may be also a factor for the development of varicoceles. Dilated peritesticular vessels may be collateral veins of spermatic veins, anterior and posterior scrotal veins, or proximal vas deferens.

The aim of the current study is to correlate Doppler flowmetry with andrological features in male goats belonging to different age and fertility groups. Thirty native crossbreed bucks bred in Northeastern Brazil were subjected to B-mode, spectral and color Doppler ultrasound, as well as to andrological examinations. Color Doppler ultrasound was used to evaluate blood flow in the pampiniform plexus and testicular parenchyma. Semen was collected through the electroejaculation method in order to have its physical and morphological features evaluated. The animals were grouped based on age (young, mature, and old) and fertility level (high and low) before analysis. Data were subjected to Poisson regression analysis. The fertile bucks have shown higher plexus and parenchyma pixel responses (P < 0.05). Old animals had the highest values for plexus and parenchyma pixels, and for parenchyma score, and they were followed by mature and young animals, respectively. There was a significant correlation among testicular vascular flows, age, testicular morphometry, and fertility; however, there was no correlation between Doppler variables and sperm morphology. In conclusion, Doppler ultrasound had a potential effect on the assessment of testicular artery hemodynamics in male goats. Thus, it can be used as a complementary tool to indicate seminal quality, or even as a potential fertility predictor.

A varicocele is an abnormal venous dilatation and/or tortuosity of the pampiniform plexus in the scrotum. The exact pathophysiology of varicoceles is not very well understood, including whether there is any effect on male infertility. They can, however, be uncomfortable or painful and may result in testicular growth arrest during and prior to puberty. Varicocoeles can cause significant anxiety in patients about infertility, testicular cancer, or appearance. This article will not only discuss how to diagnose, when to investigate, and how to treat varicoceles, but also when to leave them alone.
