A prospective study of the association between varicoceles and semen quality in men with infertility

BackgroundMale infertility is a global problem, and varicoceles are a common and treatable cause of male infertility. This study prospectively evaluated the effects of varicoceles on the fertility status and potential among Nigerian men. The consequences of the presence, location, and grades of varicoceles on the fertility status of infertile men with varicoceles were determined using a Doppler scrotal ultrasound scan and their seminal fluid parameters.MethodsOne hundred infertile males with clinical varicoceles (study group) and 100 infertile males without varicocele (control group) were recruited. Varicoceles were confirmed/excluded and graded with an ultrasound scan in each subject. They also all had a seminal fluid analysis to measure their fertility potential. The findings were compared and correlated in the two groups.ResultsMost subjects in the study group (67%) had bilateral varicoceles, 31% had isolated left varicoceles, and only 2% had isolated right varicoceles. The majority of the participants (61%) in the study group had secondary infertility, while the majority (63%) in the control group had primary infertility (p = 0.001). There were significant increases in the prevalence of azoospermia (p = 0.008) and oligospermia (p = 0.030) with the higher grades of left varicoceles.ConclusionBilateral varicoceles were significantly present in males with infertility in the study group. Varicoceles were more common in males with secondary infertility, and higher grades of varicoceles were significantly more associated with azoospermia and severe oligospermia. We recommend the routine use of ultrasound scans to diagnose varicoceles for the optimal management of infertile male patients.

Familial DMRT1-related non-obstructive azoospermia: a case report.

To report an exceptional case of male-to-male transmission of genetically based non-obstructive azoospermia (NOA) and varicocele through a naturally obtained pregnancy. A father and his son were both diagnosed with NOA after centrifugation and varicocele. The father has no other clinical concerns apart from infertility, detected after many attempts of having another child, but given his urological situation (bilateral varicocele and NOA) assisted reproductive techniques were discouraged. After genetic counseling, several genetic-chromosomal analyses were carried out in the son (karyotype, chromosome Y microdeletions, CFTR screening, NGS infertility panels, and finally array-CGH). After a series of inconclusive tests, array-CGH detected a deletion of 224-283kb (del9p24.3) involving part of the KANK1 and DMRT1 genes, inherited from the father. Haploinsufficiency of DMRT1 was therefore considered the determining factor in the development of azoospermia in the family by a loss of function mechanism. The confirmation of father-to-son transmission of a deletion including DMRT1 represents an important point for clinicians dealing with male infertility, even when complete azoospermia is repetitively detected, and must be of hope for a relevant portion of men. Inclusion criteria for the access to assisted reproductive techniques may also be reconsidered and worthy of a greater number of clinical insights. Finally, since DMRT1 alterations have been associated with NOA and abnormal testicular development, but not specifically with varicocele, further studies are required to validate this issue, as varicocele may have played a crucial role in this case.

Beyond the Incision: A Comparative Study of Suprainguinal and Inguinal Varicocele Surgeries.

Background Varicocele, characterised by the abnormal dilation of the pampiniform plexus of scrotal veins, is a prevalent and treatable cause contributing to male infertility, affecting 40% of men experiencing primary infertility and 80% of those with secondary infertility. Often asymptomatic, it can lead to chronic scrotal pain or a feeling of heaviness. Surgical interventions such as open, laparoscopic, or microsurgical varicocelectomy aim to eliminate venous reflux into the scrotum. This study sought to assess and evaluate the surgical outcomes and postoperative complications of the suprainguinal and inguinal approaches to varicocelectomy, offering evidence-based insights to improve varicocele management. Methodology A total of 60 males diagnosed with grade II or III unilateral or bilateral varicocele were included in the study. Patients with subclinical or grade I varicocele, recurrent varicocele, or concomitant inguinoscrotal pathology (hydrocele, epididymal cyst, and inguinal hernia) were excluded. Participants were randomly assigned to one of two groups based on the surgical technique: Group A (suprainguinal approach) and Group B (inguinal approach). Surgical outcomes were assessed by evaluating operating time, postoperative pain, wound hematoma, wound infection, hydrocele development, testicular atrophy, and semen analysis, both pre- and postoperatively. Results The study included 60 patients with a mean age of 29.05±5.96 years and an age range of 18-40 years. The suprainguinal approach offers a significantly shorter operating time than the inguinal approach (33.1 vs. 40.8 minutes). Both surgical techniques resulted in similar postoperative pain levels. The incidence of complications, such as wound hematoma, wound infection, and hydrocele development, showed no significant differences between the two approaches. In Group A (suprainguinal approach), the rates were 3.3%, 6.6%, and 3.3%, respectively, while in Group B (inguinal approach), they were 6.6%, 13.3%, and 6.6%. Additionally, 75% of patients in the infertility group showed improvements in semen parameters, with 80% in Group A and 71.4% in Group B, with no significant difference between the surgical approaches. Conclusion The suprainguinal and inguinal approaches to varicocelectomy effectively manage varicoceles, with the suprainguinal approach offering a shorter operating time. Postoperative complications and improvements in semen parameters were comparable between the two methods.

A Comparative Study between Laparoscopic Varicocelectomy and Open Varicocelectomy in the Treatment of Varicocele

Background: Varicocele is a vein anomaly affecting 15% of adult males, with prevalence increasing to 35% in men seeking infertility evaluation and 81% in those with secondary infertility. It is primarily due to a prevalent and remediable factor. Objective: The objective of this study is to do a comparative analysis of the post-operative outcomes between open inguinal varicocelectomy and laparoscopic varicocelectomy. Methods: The present investigation was undertaken within the surgical department of (Hospital name) over a duration of two years, spanning from December 2019 to December 2021. This study employed a prospective design and involved the inclusion of a cohort comprising 50 patients diagnosed with clinically severe varicocele. The participants were allocated into two distinct groups. Group A consisted of 25 individuals who underwent laparoscopic surgery, while Group B consisted of 25 individuals who received an open approach. Results: In our study comprising a cohort of 50 patients, we observed a range of ages from 20 to 49 years. Among these patients, 19 reported experiencing scrotal pain, 25 exhibited testicular swelling, and 7 presented with infertility. The mean operation time for laparoscopic varicocelectomy was 48 minutes, while for open surgery it was 57 minutes. Interestingly, we found that the postoperative analgesic requirement was similar in both groups. Furthermore, the average duration of hospital stay was 35.6 hours for laparoscopic procedures and 50.6 hours for open procedures. The duration of the operative procedure in Laparoscopic Varicocelectomy was found to be 17.25 ± 2.1 minutes in cases where the condition was unilateral, whereas it was 29.32 ± 2.8 minutes in situations where the condition was bilateral. The average length of surgery for unilateral cases in Open Varicocelectomy was found to be 42.5 ± 3.4 minutes, whereas for bilateral presentations, it was 67.25 ± 2.5 minutes. The observed difference between the two groups was found to be statistically significant, with a p-value of less than 0.001 . The recurrence rate was higher in laparoscopic group. Conclusion: Laparoscopic varicocelectomy offers similar outcomes to open techniques, with minimal morbidity and shorter hospitalization periods. It treats bilateral varicoceles without extra incisions and has a higher recurrence rate, but overall patient satisfaction makes it a preferred surgical technique.

Comparative Study between Open and Laparoscopic Varicocelectomy in Bilateral Varicocele

Comparative Study between Open and Laparoscopic Varicocelectomy in Bilateral Varicocele

Microscopic subinguinal varicocelectomy with video telescopic operating microscope (VITOM) telescope: outcome analysis.

Conventional techniques of varicocele repair are associated with substantial risks of hydrocele formation, ligation of the testicular artery, and varicocele recurrence. The advantages of the microscopic approach to varicocele repairs are detailed identification and preservation of the vascular structures. In this study, our purpose is to review the outcome of all patients that underwent microscopic subinguinal varicocelectomy with the video telescopic operating microscope (VITOM). Hence, a retrospective review of 23 varicocele patients who underwent microscopic subinguinal varicocelectomy at the center from the year 2019 until 2021 was done. They, ranging between 18 to 58 years of age, comprising one case of right varicocele, fifteen cases of left varicocele, and seven cases of bilateral varicocele, were all having symptoms (pain and swelling) and clinically palpable varicocele. Ultrasounds were done to confirm the diagnosis and measure the testicular size. The surgery was performed by a single surgeon, under spinal anesthesia. The operation was performed using the VITOM telescope system, with an average operative time of one hour. The patients were followed-up at one month postoperatively to review the wound and symptoms. Phone call evaluations of all 23 patients were done to detect any recurrence or complications. All patients were discharged one day after surgery. Post-operative, all of them have a well-formed scar at the previous subinguinal region incision wound during the clinic visits. None of the 23 patients reported with varicocele recurrence, testicular pain, hydrocele formation or sexual dysfunction. The previous testicular pain or discomfort they encountered prior to the surgery was resolved as well. In conclusion, microscopic subinguinal varicocelectomy using the VITOM telescope is feasible and could achieve good outcomes.

Comparative evaluation of visual-palpatory findings with scrotal doppler ultrasound data for varicocele diagnosis

Introduction. Current evidence suggests that management of any grade of varicocele can improve male fertility. However, diagnosis of grade 1 varicocele in infertile men without the use of scrotal Doppler ultrasound may cause overtreatment.Objective. To study the comparability and accuracy of the visual palpatory examination method with the scrotal Doppler ultrasound data for the diagnosis of varicocele.Material & methods. Between November 2005 to January 2022, 2871 patients diagnosed with varicocele and infertility who underwent microsurgical varicocelectomy by inguinal access were examined at RSSPMCU. The average age of the patients was 30.16 ± 0.09 (18 – 60) years. Of the 2871 patients, 2592 (90.3%) were diagnosed by physical examination, and 279 (9.7%) patients underwent additional scrotal Dopper ultrasound.Results. After Doppler scrotal imaging was introduced into practice, the proportion of patients with bilateral varicocele increased from 32.2% to 61.6% (p < 0.01). The proportion of patients with right-sided varicocele also increased significantly. Experienced physicians during physical examination of infertility patients did not diagnose grade 1 varicocele in 4.3%.Conclusions. The implementation of scrotal Doppler ultrasound for the diagnosis of male infertility improved the detection of grade 1 varicocele and bilateral varicocele. In turn, this contributed to earlier elimination of the male factor of infertility in this contingent of patients.

(271) Assessment of Varicocele Bilaterality in Infertile Men

Abstract Introduction Varicocele is the most common correctable cause of male factor infertility. It has always been a debatable subject as regard how it affects fertility and the best way to treat. However, there is a wide consensus nowadays that varicocelectomy improve male fertility potentials. Proper assessment of the disease bilaterality is crucial not to miss one side and not to jeopardize treatment outcome. Objective The primary outcome measure was to assess disease bilaterality and the secondary outcome measure was to report on improvement in semen 3 and 6 months post varicocelectomy and pregnancy rate 1 year post surgery. Methods This prospective study was conducted between January 2019 and January 2022. Infertile males with varicoceles underwent microsurgical subinguinal varicocelectomy by expert uroandrologists. Patients who were referred as unilateral varicoceles had their CDUS repeated for assessment of missed concomitant contralateral varicocele. Then, patients who were diagnosed with bilateral varicoceles underwent bilateral subinguinal ligation straight away. Those who were referred with unilateral varicocele had their palpable sides operated on first; then the contralateral side was also explored using an intraoperative Doppler device and the maximal vein diameter was measured. Patients came for follow for at least 6 months after surgery to evaluate any complications and assess improvement in semen parameters. Gynecologists also reported on normal pregnancy rate 1 year after surgery. Results A total of 329 cases completed the study. A hundred cases (30.4%) were initially referred as unilateral varicoceles and 229 (69.6%) as bilateral varicoceles. After reassessment of the study population, bilaterality of varicocele was found to be as high as 98.5% (324/329). This is statistically significantly higher than initial US (P<0.001). Repeat CDUS strongly correlated with the intraoperative measured varicocele diameter [r=0.9, P<0.001]. Moreover, sperm parameters showed significant improvement 3 and 6 months post varicocelectomy. Normal pregnancy after 1 year of surgery occurred in 118 cases (35.9%). Conclusions Varicocele bilaterality is underreported. Thorough assessment by expert radiologists and andrologists is of paramount importance not to miss significant pathology or hazard treatment outcome. Disclosure No.

Video-Assisted Telescope Operating Monitor 3D System in Microsurgical Varicocelectomy: A Preliminary Report.

Video-assisted telescope operating monitor (VITOM®) with 3D Visualization technology was developed and has been used with favorable results by several surgical specialties. Our study aims to be a preliminary report for initial experience using the VITOM® 3D system for microsurgical varicocelectomy on varicocele patients. We performed 35 microsurgical varicocelectomy procedures using the VITOM® 3D system on varying types and grades of varicoceles. The surgeon had the option of using either a 2.5 or 3.5 magnifying loupe in addition to the exoscope for each operation evaluated. The exoscope is a standalone camera head with an integrated 3D telescope and remote control with zoom and focus functions. It is connected to the 3D monitor via a mechanical holding arm. During the procedure, surgeons, assistants, and observers were able to view the 3D high-definition stream displayed on a 26-inch 3D monitor at a convenient viewing angle and distance. The varicocele ligation was performed using a Carl Zeiss Meditec AG microscope. There were 35 patients with varicocele aged 31.51years old on average, which were included in this report. Most patients had grade 3 bilateral varicocele (n = 13, 37.1%). All procedures were performed without any intraoperative complications. After the procedures, only a few patients suffered from postoperative complications. Three patients suffered scrotal edema (8.6%), while another had hydrocele (2.9%). The postoperative pain results were also very minimal from .89 1day after the operation to .26 3days after the operation. The VITOM® 3D system showed promise in microsurgical varicocelectomy.

Management of Normogonadotropic males with idiopathic infertility with bilateral varicocelectomy with and without intramuscular recombinant FSH and HCG course(s): A twenty-year- experience in a prospective, controlled, and randomized clinical study

This study presents a clinical prospective double-blinded study that contains three groups of infertile males with normogonadotropic oligoasthenospermia. All groups A, B, and C were operated on for their bilateral varicoceles. The first included 152 patients who were only operated for bilateral varicocele (nominated group A). The second group of 237 patients constituted those who were operated on, with fertile female partners, and whose preoperative spermogram showed a count lower than 15 million/ml and a 3-hour-motility lower than 20%. This group constituted two categories based on their treatment. Therefore, groups B and C received postoperative courses of intramuscular injections of recombinant follicle-stimulating hormone (rFSH) and human chorionic gonadotropin (HCG), i.e., group B received one course (3 months), and group C received two courses (6 months). The main objective is to determine the improvement in the postoperative seminal parameters in the different groups. The sample constituted 391 infertile males who were recruited conveniently based on their willingness to share their progress information and were also informed that they could stop their participation freely with no questions asked. In our treated patients, in both groups B and C, who received 1 or 2 courses of rFSH and HCG, spontaneous pregnancy occurred in 69 patients and 52 patients, respectively. Likewise, assisted pregnancy occurred in 28 and 19 patients, respectively. So treated males of groups B and C resulted in 91/140 (65%) and 61/96 (63.54%) live offspring, respectively.

The Urgency of Karyotyping Examination in Male Infertility Patients with Primary Hypogonadism

Infertility is a failure to get pregnant after one year of sexual intercourse without using contraception. The causes of infertility, especially in men, are very complex, including the aging process, hormonal disorders, lifestyle, environment, metabolic disease, and genetic problems. One of the most difficult causes in male infertility is genetic problems. In this case, a 35 year old man was reported with primary infertility and often experienced premature ejaculation and even anejaculation. Previously, the patient had repeatedly consulted about his condition at other fertility service centers. The conclusion obtained was that the patient had azoospermia with bilateral varicoceles and had been given hormone therapy but had not yet found a final diagnosis so the patient was still confused about what had happened to him. At the first visit the patient underwent a sperm analysis and the results were azoospermia. Then, based on the results of the history and physical examination, which indicated hypogonadism, a Y chromosome microdeletion examination was carried out, and a deletion was found in the AZFc region, which is a marker of infertility that causes spermatogenic failure. The examination was continued with karyotyping, the result was 47.XXY, consistent with the condition of Klinefelter syndrome. Conclusion: Carry out a karyotyping examination if you find signs and symptoms that suggest primary hypogonadism in male infertility. This can be done to streamline the diagnostic approach time in patients with primary hypogonadism, especially those with infertility.

Effect of varicocele surgery on sperm quality

Introduction: A varicocele is a vascular lesion characterised by dilatation and tortuosity of the veins of the pampiniform plexus and is found in approximately one-fifth of the adult male population. It is the most common cause of treatable infertility. Physical examination may or may not show a varicocele which is mostly diagnosed only when patients present with infertility or adolescents during a physical examination, like testicular hypotrophy, impairment in spermatogenesis mainly in the form of low or absent count, decreased sperm motility, and abnormal sperm morphology. Treatment for varicocele includes medical therapies, radiological embolization, and surgical techniques. Medical therapy, including antioxidants and anti-inflammatory agents, has been utilized with variable success. Radiological embolization of varicocele is a new technique in the treatment of varicocele, but it is associated with high recurrences and high cost. Varicoceles are surgically treated either by open or laparoscopic approaches the principal aim being occlusion of the dilated veins of the pampiniform plexus. A definitive conclusion of indication of medical treatment cannot be drawn at present because most published studies have inadequate design and lack controls. Various studies in the past have concluded significant changes in sperm parameters (total count, motility, morphology) post-varicocele repair. However, few other studies suggest no improvement in sperm parameters following surgical varicocele repair and studies that conclude recommendations against repair of varicocele. Thus, conflicting opinions have opened the scope to establish this fact by this study. Aim: To evaluate changes in sperm morphology, sperm count, and sperm motility in a patient with varicocele after varicocele surgery. Materials and methods: The study was conducted in the Department of Surgery, North Delhi Municipal Corporation Medical College & Hindu Rao Hospital, Delhi, India from August 2019 to February 2021. The sample size was calculated to be 50 using Slovin’s formula with a confidence level of 95% with a margin error taken as 5% (p - value 0.05). Sperm morphology, sperm count, and sperm motility were the parameters studied before and after 3 months of surgery. Results: The majority of patients belonged to the age group of 18 to 25 years (42%) followed by 26 to 35 years (40%) (27.78 ± 6.547 years). Left-sided varicocele was more common (54%), followed by bilateral varicocele (42%). Varicocele grade II was most common (58%) followed by grade I (30%) and lastly grade III (12%). Total sperm count improved by 8.88 million per ml after varicocelectomy. Total sperm motility improved by 6.08% after the surgery. Total normal sperm forms improved by 6.44% after varicocele repair. Conclusion: Based on the findings it was concluded that Varicocelectomy results in significant improvement in total sperm count, total sperm motility, and total normal sperm morphology. The best improvement was seen in sperm count followed by total normal sperm forms and lastly total sperm motility.

A case of successful fertility of a patient with bilateral varicocele on the background of May–Thurner syndrome by combining transscrotal varicocelectomy with X-ray endovascular correction of iliac vessel compression

Arteriovenous conflicts of the ileocecal segment are a frequent cause of recurrent and bilateral varicocele. Insufficient and untimely diagnosis of varicocele causes in this group of patients leads to multiple repeated surgical interventions due to recurrence. This paper presents a clinical case of successful fertility of a 30-year-old patient with bilateral varicocele and testicular hypotrophy on the background of MeyThurner syndrome by two-stage surgical treatment including transsclerotal ligation of testicular veins, angioplasty and stenting of the left common iliac vein.

Seminal TEX101 May Predict Seminal Sperm Recovery after Varicocelectomy in Nonobstructive Azoospermic Patients with Varicocele

Background. Infertile men with nonobstructive azoospermia (NOA) associated with varicocele may benefit from varicocele repair with recovered sperms in semen. Currently, there is no clinically applied method to predict the success of seminal sperm recovery in this subset of azoospermic men. Objective. We aimed to evaluate the predictive role of the seminal testis expressed protein (TEX101) in sperm recovery in the semen of NOA men with palpable bilateral varicocele after microsurgical varicocelectomy. Patients and Methods. This prospective cross-sectional cohort study included 40 patients with NOA and bilateral varicocele. Seminal TEX101 levels were measured followed by subinguinal microsurgical varicocele repair. Two seminal analyses were carried out at 3- and 6-month follow-up periods to evaluate seminal sperm recovery. Results. After varicocele repair, sperms were recovered in the semen of 10/40 patients (25%) along the follow-up periods (seven patients after 3 months and additional three patients after 6 months). The preoperative median seminal TEX101 level was significantly higher in NOA men with seminal sperm recovery compared with NOA patients without seminal sperm recovery (13.5 vs. 9.8 ng/ml, p = 0.014 ). Besides, the serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) median levels were significantly higher in NOA men without seminal sperm recovery compared with NOA men with seminal sperm recovery ( p = 0.001 , p = 0.01 ). There were nonsignificant differences comparing the preoperative testicular volume or serum testosterone levels between the two investigated groups ( p = 0.072 , p = 0.272 ). A cutoff value of 9.9 ng/ml was demonstrated to have preoperative TEX101 prediction of seminal sperm recovery (sensitivity of 90% and specificity of 57%). Conclusion. Preoperative seminal TEX101 could be considered as a biomarker for sperm recovery for seminal sperm recovery in NOA cases associated with varicocele after its surgical repair. Further work at this point with larger number of cases should be carried out to verify its potential importance.

Bilaterality of varicocele: The overlooked culprit in male infertility. Case series study.

Varicocele is the most common correctable cause of male infertility that always has been a debatable subject as regards how it affects fertility and the best way to treat it. Proper assessment of the disease bilaterality is crucial not to miss one side and not to jeopardize treatment outcome. This study aimed to objectively assess varicocele bilaterality in infertile men aiming to improve treatment outcome in this cohort of patients. This prospective study was conducted between January 2019 and January 2022 including infertile males with varicoceles. Assessment of missed concomitant contralateral varicocele done pre-operatively by Color Doppler Ultrasound and intraoperatively by intraoperative Doppler device and measurement of maximal vein diameter of contralateral side. A total of 329 cases completed the study. A hundred cases (30.4%) were initially referred as unilateral varicoceles and 229 (69.6%) as bilateral varicoceles. After reassessment of the study population, bilaterality of varicocele was found to be as high as 98.5% (324/329). Repeat CDUS strongly correlated with the intraoperative measured varicocele diameter (r = 0.9, p < 0.001). Moreover, sperm parameters showed significant improvement 3 and 6 months post varicocelectomy. Normal pregnancy after 1 year of surgery occurred in 118 cases (35.9%). Varicocele bilaterality in infertile men is underreported. Thorough assessment by expert radiologists and andrologists is of paramount importance not to miss significant pathology or hazard treatment outcome.

Varicocele Surgery: Three Years Experience

Despite available treatments like varicocelectomy, a standard therapy remains controversial. Varicocele repair has shown promise in improving sperm parameters, but further research is needed, especially in nonobstructive azoospermia cases. Techniques such as microscopic testicular sperm extraction and intracytoplasmic sperm injection have shown some success in achieving pregnancies. Objective: To articulate our hands-on experience and understanding pertaining to varicocele. Methods: This study included patients who presented to our clinic due to varicocele and underwent surgical procedures between November 2020 and January 2023. Results: This research involved 26 varicocele patients, primarily age rage was 27.5 years old. The majority (85%) had varicocele on the left side, and 15% had bilateral varicocele. The mean vein diameter was 3.58mm and 2.6mm for the left side and bilateral cases respectively, with a general average of 3.45mm. Analysis of sperm count, motility, and morphology reflected an average of 32.6 million/ml, 23.2%, and 5.23%, respectively. An average of 4.45 veins was ligated during surgery, with a slight variance based on the side. One patient lost approximately 85% of the testicular blood supply due to a complication during surgery, leading to testicle hardening without atrophy. Two patients experienced recurrence (7.6% recurrence rate). Negative and positive correlations were found between the number of ligated veins and preoperative sperm count (p=0.043, r=-0.408), and vein diameter and preoperative sperm morphology (p=0.004, r=0.544), respectively. Conclusions: Despite the limitations, our study provides valuable insights into the relationship between varicocele severity and sperm parameters.

Microsurgical Varicocelectomy: Experience of Our Sub-Subinguinal Approach and Review of the Literature

Objective. To discuss the experience with a novel surgical approach in the treatment of varicocele for fertility or pain in 772 patients. Methods. Retrospective analysis of 772 patients undergoing microsurgical sub-subinguinal (SSI) varicocelectomy in our hospital and the discussion of historical surgical approaches. Results. A total of 690 patients with left varicocele underwent surgical treatment for infertility (n = 519) and pain (n = 171). The sperm concentrations (mean ± standard deviation (SD)) of 519 patients measured preoperatively, 6 months postoperatively, and 12 months postoperatively were 19.24 ± 3.69 (106/ml), 27.42 ± 10.32 (106/ml), and 34.20 ± 16.29 (106/ml) ( ∗ ∗ P &lt; 0.01 ), respectively. The sperm motilities (mean ± SD) of 519 patients measured preoperatively, 6 months postoperatively, and 12 months postoperatively were 13.78 ± 3.25, 20.98 ± 8.21, and 27.59 ± 13.71 (grade (a + b) %) ( ∗ ∗ P &lt; 0.01 ), respectively. Pain was released surgically in 131 (76.6%) of the 171 patients. A total of 82 patients with bilateral varicocele underwent surgical treatment for infertility (n = 58) and pain (n = 24). The sperm concentrations (mean ± SD) of 58 patients measured preoperatively, 6 months postoperatively, and 12 months postoperatively were 19.21 ± 3.24 (106/ml), 27.36 ± 10.26 (106/ml), and 33.87 ± 15.20 (106/ml) ( ∗ ∗ P &lt; 0.01 ), respectively. The sperm motilities (mean ± SD) of 58 patients measured preoperatively, 6 months postoperatively, and 12 months postoperatively were 13.54 ± 2.75, 20.75 ± 8.21, and 28.53 ± 14.83 (grade (a + b) %) ( ∗ ∗ P &lt; 0.01 ), respectively. Pain was released surgically in 19 (79.2%) of the 24 patients. The probability of occurrence in one artery, two arteries, three arteries, and more than three arteries was 29.5%, 28.8%, 19.9%, and 1.9%, respectively. Conclusion. This surgical approach achieves a small and esthetic skin wound with fewer complications. The SSI approach is a safe and widely adopted surgical approach option for the treatment of varicocele.
