OBJECTIVE: Androgen deficiency is common in aging males and may have unfavourable health consequences. Large-scale studies suggested low testosterone level might increse mortality and morbidity in ageing males. However, young men with low testosterone level might be neglected. Recent studies reported young men with infertility may have reduced testosterone level. To investigate the incidence of androgen deficiency in males with infertility and possible factors affecting the low testosterone level. METHODS: Between January 2011 and December 2012, 407 men with infertility caused by varicocele (VC), obstructive azoospermia (OA) and nonobstructive azoospermia (NOA) in our center were included. The number of men in each group of OA, NOA and VC was 141, 97 and 169, respectively. All the eligible patients underwent a serum testosterone assessment by a single morning blood draw (between 8:00 to noon) to test for concentration of the total testosterone. All serum samples were determined by radioimmunoassay in our andrology laboratory. Androgen deficiency was defined as having a total testosterone level less than 300 ng/dL. RESULTS: The mean age was (30.4±5.8) years. The mean testosterone level was (4.18±1.64) ng/dL (range 0.30 to 11.32 ng/dL). The overall incidence of androgen deficiency was 26.5% (108/407). The incidences of androgen deficiency in NOA, OA and VC groups were 40.2% (39/97), 19.1% (27/141) and 24.9% (42/169), respectively, which were significantly higher in the NOA than in the VC and OA groups (P < 0.001). The incidences had no difference between the VC and OA groups (P=0.229). Univariate analysis revealed the cause of infertility, FSH and the mean testis volume as possible affecting factors for androgen deficiency. However, on multivariate analysis the only cause of infertility was an independent predictor. The incidence of androgen deficiency was the highest in the NOA group [OR 0.492 (95% confidence interval 0.288-0.840)]. CONCLUSION NOA and varicocele might be risk factors of androgen deficiency. Young men with NOA may have a higher possibility of low testosterone level. Testosterone level should be followed up after NOA and varicocele treatment. Androgen deficiency should be assessed in males with infertility in clinical practice.

ObjectiveTo compare the clinical effects and postoperative complications of microsurgical subinguinal varicocelectomy (MSV) with or without delivery of the testis and ligation of gubernacular veins in the treatment of varicocele.

METHODSWe retrospectively analyzed the clinical data about 163 varicocele patients treated by MSV, 40 with (group A) and the other 123 without delivery of the testis and ligation of gubernacular veins (group B). We compared the operation time, postoperative complications, rate of recurrence, and semen parameters before and at 3 months after surgery between the two groups of patients.

RESULTSThe operation time was significantly longer in group A than in B (［81.1 ± 20.0］ vs ［62.3 ± 9.6］ min, P = 0.041). Sperm concentration, total sperm count per ejaculate, sperm viability, and the percentage of progressively motile sperm were significantly improved in both groups at 3 months after MSV as compared with the baseline (P < 0.05). There were no statistically significant differences in the above semen parameters between the two groups of patients with grade Ⅲ varicocele before and after surgery (P < 0.05). Scrotal edema developed in 5 cases in group A and wound infection in 2 cases in group B after MSV, but no postoperative testicular atrophy or recurrence was observed in either of the two groups.

CONCLUSIONSMSV with delivery of the testis and ligation of gubernacular veins showed no advantages over that without in reducing varicocele recurrence and improving semen parameters, but rather involved longer operation time and a higher incidence rate of postoperative complications.

The therapeutic decision for male infertility with varicocele is difficult and controversial, which requires the consideration of the patient's purpose of seeking medical help. The treatment of this condition involves not only surgery, but also medication and assisted reproductive technique (ART), and synergetic effects can be achieved by combination of the three options. In making a therapeutic decision, all related factors should be taken into full consideration.

Objective: To investigate the effect of laparoscopic extraperitoneal (LSEP) high ligation of the spermatic vein in the treatment of varicocele. METHODS: We retrospectively analyzed the clinical data about 80 cases of varieocele, 48 treated by LSEP and the other 32 by laparoscopic transabdominal retroperitoneal (LSTR) high ligation of the spermatic vein. We recorded the semen parameters before and at 1, 3 and 6 months after surgery, intraoperative blood loss, operation time, postoperative complications, time of gastrointestinal function recovery and rate of pregnancy, followed by comparison of the data obtained between the two groups of patients. RESULTS: Semen parameters were remarkably improved in both the LSEP and LSTR groups of patients postoperatively as compared with the baseline (P <0.05), but with no statistically significant difference at different postoperative months (P >0.05). The intraoperative blood loss was less in the LSEP than in the LSTR group (［8.3 ± 5.2］ vs ［9.1 ± 6.1］ ml, P >0.05), the operation time was shorter in the former than in the latter (［38.27 ± 9.23］ vs ［43.46 ± 11.72］ min, P >0.05), and so was the time of gastrointestinal function recovery (［1.27 ± 0.26］ vs ［2.43 ± 0.41］ d, P <0.05). No statistically significant differences were observed between the two groups during the 6- to 18-month follow-up in the rates of postoperative subcutaneous hematoma, scrotal and subcutaneous emphysema, recurrence, or pregnancy (P >0.05). CONCLUSIONS Laparoscopic extraperitoneal high ligation of the spermatic vein is safe and effective and has the advantage of quick recovery in the treatment of varicocele.

Objective: To investigate the clinical effect and feasibility of internal spermatic vein-inferior epigastric vein (ISV-IEV) bypass surgery in the treatment of varicocele complicated by left renal vein nutcracker syndrome (NCS). METHODS: We retrospectively analyzed the clinical data about 30 cases of varicocele with left renal vein NCS treated by ISV-IEV bypass surgery in our hospital from June 2014 to February 2017. We reviewed the follow-up data and results of ultrasonography, routine urianlysis and semen routine examination. RESULTS: All the operations were successfully accomplished and postoperative color Doppler ultrasonography showed that varicocele was cured in all the cases. At 6 months after surgery, sperm concentration and the percentage of grade a+b sperm were significantly improved (［34.47 ± 8.60］ ×10⁶/ml and ［63.54% ± 9.58］ %) as compared with the baseline (［19.90 ± 8.97］ ×10⁶/ml and ［37.93 ± 8.73］ %) (P <0.05). Hematuria was cured in 23 and alleviated in 1 of the 24 cases. Proteinuria disappeared in all the 14 cases, with neither scrotal pain symptoms nor obvious complications. CONCLUSIONS ISV-IEV bypass surgery, with its advantages of safety, effectiveness, minimal invasiveness, and simple operation, deserves wide clinical application in the treatment of varicocele with left renal vein NCS.

Objective: To investigate the clinical effect of microscopic spermatic vein ligation in the treatment of nutcracker phenomenon (NCP) complicated with left varicocele (VC). METHODS: This retrospective study included 31 cases of NCP complicated with left VC treated in our hospital by subinguinal microscopic ligation of the left spermatic vein (group A, n = 11), open retroperitoneal high ligation of the left spermatic vein (group B, n = 11), or conservative therapy (group C, n = 9). The patients were followed up for 6－24 (15.3 ± 5.4) months. We compared the semen parameters, spermatic vein diameter, left testis volume, and recurrence rate among the three groups of patients before and after treatment. RESULTS: Compared with the baseline, the semen quality parameters were significantly improved in both groups A and B at 6 months after treatment (P<0.05) but reduced in group C (P<0.05); the spermatic vein diameter at rest and that at Valsalva maneuver were markedly decreased in groups A (［2.53 ± 0.27］ vs ［1.84 ± 0.22］ and ［3.53 ± 0.19］ vs ［2.16 ± 0.25］ mm, P<0.05) and B (［2.62 ± 0.33］ vs ［2.15 ± 0.43］ and ［3.36 ± 0.25］ vs ［2.44 ± 0.27］ mm, P<0.05) but increased in group C (［2.56 ± 0.28］ vs ［2.94 ± 0.24］ and ［3.33 ± 0.21］ vs ［3.77 ± 0.26］ mm, P<0.05). No statistically significant differences were found in the left testis volume at 6 months after treatment in group A (［9.85 ± 1.86］ vs ［10.27 ± 1.18］ ml, P>0.05), B (［9.77 ± 2.03］ vs ［9.96 ± 1.72］ ml, P>0.05), or C (［9.83 ± 1.59］ vs ［10.48 ± 2.05］ ml, P>0.05), nor in the recurrence rate between groups A and B (P>0.05). CONCLUSIONS Hematuria, proteinuria and other mild symptoms of nutcracker phenomenon complicated with left VC can be treated palliatively by microscopic ligation of the spermatic vein, which can relieve the clinical symptoms, improve the semen quality, and protect the testicular function of the patient.

ObjectiveTo investigate the clinical effect of Jujing No.2 Decoction on male infertility induced by varicocele.

METHODSWe equally randomized 70 male patients with varicocele-induced infertility into a treatment group and a control group, the former treated with modified Jujing No.2 Decoction (1 dose a day, bid) and the latter given Danshen Tablets (4 tablets once, tid) plus Liu Wei Di Huang Wan (8 pills once, tid), both for 3 months. We examined the spermatic veins of the patients by ultrasonography and performed seminal analysis before and after medication.

RESULTSCompared with the controls, the patients in the treatment group showed significant improvement after medication in sperm concentration (［12.35±2.12］ vs ［18.56±4.16］ ×10⁶/ml, P<0.05), progressively motile sperm (［16.18±6.34］ vs ［24.63±8.51］ %, P<0.05), and morphologically normal sperm (［11.59±5.31］ vs ［14.17±6.02］ %, P<0.05). In the control group, sperm concentration was increased from (12.29±2.07) ×10⁶/ml at the baseline to (13.13±3.13) ×10⁶/ml after medication, progressively motile sperm from (16.13±6.45) % to (20.55±7.30) % (P<0.05), and morphologically normal sperm from (11.62±5.35) % to (12.69±5.77) %. The total effectiveness rate was significantly higher in the treatment than in the control group (71.88% vs 46.67%, P<0.05). The inner diameter of the left spermatic vein was decreased from (0.32±0.05) mm at the baseline to ［0.26±0.05］ mm after medication in the treatment group (P<0.05) and from (0.32±0.03) mm to (0.29±0.04) mm in the control (P<0.05), with statistically significant difference between the two groups after medication (P<0.05).

CONCLUSIONSJujing No.2 Decoction is effective in the treatment of varicocele-induced male infertility.

ObjectiveTo investigate the relationship of oxidative stress with DNA integrity and semen parameters in infertile men with varicocele (VC).

METHODSThis prospective study included 98 infertile males with VC. According to the levels of reactive oxygen species (ROS) in the semen, we divided the patients into a high ROS group (n=44) and a low ROS group (n=54), determined the sperm DNA fragmentation index (DFI), motility and morphology, and analyzed their correlation with ROS in the two groups of patients.

RESULTSCompared with the patients of the low ROS group, those of the high ROS group showed a significantly higher DFI (27.38±8.10 vs 34.49±6.05, P=0.039) and a higher concentration of seminal leukocytes (［0.65±0.15］×10⁶/ml vs ［0.86±0.41］×10⁶/ml, P=0.022), but lower sperm motility (［36.16±22.83］% vs ［18.22±25.21］%, P=0.017), percentage of progressively motile sperm (［23.34±11.53］% vs ［16.34±9.22］%, P=0.041), sperm curvilinear velocity (［27.03±6.21］ vs ［20.62±4.38］ μm/s, P=0.013), and sperm linearity (［29.75±8.24］% vs ［18.30±7.93］%, P=0.024). Spearman correlation analysis indicated that the ROS level was correlated positively with the concentration of seminal leukocytes (r=0.41, P<0.01) and DFI (r=0.21, P=0.006), but negatively with sperm curvilinear velocity (r=－0.24, P=0.017), linearity (r=－0.24, P=0.021), motility (r=－0.31, P=0.002), and the percentage of progressively motile sperm (r=－0.41, P=0.012). Additionally, the sperm DFI manifested a significant negative correlation with sperm motility (r=－0.29, P<0.01) and the percentage of progressively motile sperm (r=－0.34, P<0.01).

CONCLUSIONSThe level of seminal ROS is positively correlated with the sperm DFI in infertile men with varicocele, and both the ROS level and DNA integrity are associated with semen parameters.

OBJECTIVETo study the impact of left varicocele (VC) and varicocelectomy (VCT) on the apoptosis of spermatogenic cells and the levels of nitrogen monoxidum (NO) and interleukin 1 (IL-1) in the rat testis.

METHODSWe randomly divided 60 adolescent male SD rats into four groups of equal number: sham operation control, VC model 1 (VC1), VC model 2 (VC2), and VCT. We determined the semen quality and levels of NO and IL-1 in the testis tissue, detected the apoptosis of spermatogenic cells by TUNEL, and compared the indexes obtained among different groups.

RESULTSAn experimental VC model was successfully established by partially ligating the left renal vein of the rats. Sperm concentration and motility were significantly decreased in the VC1 ([1.54 ± 1.16] x 10⁶/ml and [44.23 ± 15.46]%) as compared with those in the sham operation group ([2.80 ± 1.62] x 10⁶/ml and [72.34 ± 12.62]%) (P < 0.05), but remarkably higher in the VCT ([1.82 ± 1.34] x 10⁶/mI and [51.21 ± 12.62]%) than in the VC2 group ([1.04 ± 1.21] x 10⁶/ml and [39.23 ± 13.21]%) (P < 0.05). The levels of NO and IL-1 in the left testes were markedly elevated in the VC1 ([0.172 ± 0.030] ng/ml and [1.468 ± 0.080 ] mg/ml) in comparison with those in the sham operation group ([0.134 ± 0.021] ng/ml and [0.782 ± 0.079 ] mg/ml) (P < 0.05), and significantly higher in the VC2 ([0.198 ± 0.020] ng/ml and [1.994 ± 0.090] mg/ml) than in the VCT group ([0.141 ± 0.010] ng/ml and [0.781 ± 0.036] mg/ml) (P < 0.05). However, the NO and IL-1 levels in the right testis showed no statistically significant differences between the two groups, and the two levels were positively correlated (r = 0.492, P < 0.01). The rats of the VC1 group exhibited remarkable apoptosis of spermatogenic cells in the bilateral testes, with significant differences in the apoptosis index ( AL) between the two sides (P < 0.05) as well as in the same side in comparison with the sham operation group (P < 0.01). The Als of spermatogenic cells in the bilateral testes showed statistically significant differences in the VCT (P < 0.05) but not in the VC2 group (P > 0.05), and those in the same side manifested dramatic differences between the VCT and VC2 groups (P < 0.01).

CONCLUSIONVaricocele induces changes of the NO and IL-1 levels in the testis tissue and increases the apoptosis of spermatogenic cells, which might be one of the causes of testis damage and spermatogenic dysfunction.
