The efficacy and mechanism of acupuncture in the treatment of male infertility: A literature review.

Fertility, a social, cultural, and medical issue, has aroused public attention because of its potential to predict future health. In recent years, the incidence of male infertility has increased significantly, and various risk factors, such as congenital factors, acquired factors, and idiopathic factors, have led to this situation. Male infertility causes substantial psychological and social distress in patients. With the implementation of the two-child policy, male infertility has brought enormous psychological and social pressure and huge economic burden to patients and the healthcare system. This has attracted the attention of not only men of childbearing age but also many male experts. The conventional therapeutic approaches for treating male infertility, including drugs, varicocele surgery, intrauterine insemination, in vitro fertilization, and intracytoplasmic sperm injection, can restore fertility to a certain extent, but their efficacy is far from satisfactory, not to mention some adverse events. Therefore, acupuncture has been chosen by many men to treat their infertility and produced significant effects. In the present paper, the efficacy and mechanism of acupuncture in the treatment of male infertility were analyzed from different perspectives such as regulating hormone secretion, reducing inflammation, and improving semen parameters. The existing literature shows that acupuncture can effectively treat male infertility.

Improvement in sperm quality by oral antioxidant supplementation in infertile men with varicocele who have not undergone surgical repair: Systematic review and meta-analysis.

The aim of this systematic review and meta-analysis was to assess whether oral antioxidant supplementation improves sperm quality in men with infertility and varicocele (VCL) who have not undergone surgical repair. In men with infertility and VCL who had not undergone surgical repair oral antioxidant supplementation significantly increased sperm concentration (WMD +5.86 × 106 /ml 95% CI: +1.47 to +10.24, p < 0.01; random effects model, six studies, 213 patients), total motility (WMD + 3.76%, 95% CI: +0.18 to +7.34, p = 0.04; random effects model, three studies, 93 patients), progressive motility (WMD + 6.38%, 95% CI: +3.04 to +9.71, p < 0.01; random effects model, three studies, 84 patients) and seminal volume (WMD +0.55 ml, 95%CI: +0.06 to +1.04, p = 0.03; random effects model, four studies, 120 patients). On the other hand, no significance difference was observed in sperm morphology (WMD +3.89%, 95% CI: -0.14 to +7.92, p = 0.06; random effects model, five studies, 187 patients). In conclusion, limited evidence suggests that the use of oral antioxidants in men with infertility and VCL, who have not undergone surgical repair improves their seminal volume, sperm concentration, total and progressive motility.

[Danhong Tongjing Prescription versus microsurgery in the treatment of varicocele-induced infertility: A retrospective multivariate analysis of 218 cases].

OBJECTIVE: To compared the traditional Chinese medicine Danhong Tongjing Prescription (DTP) and microsurgery in the treatment of varicocele (VC)-induced infertility and investigate the factors influencing the recovery of semen parameters of the patients. METHODS: We retrospectively analyzed the clinical data on 218 cases of VC-induced infertility with qi-deficiency and blood-stasis treated with DTP (n = 86) or by microsurgery (n = 132) in our hospital from January 2017 to July 2019, and compared the semen parameters between the two groups of patients after treatment. With age, course of disease, degree of VC, change of the testis volume, estrogen/testosterone (E/T) ratio and levels of FSH and LH as independent variables, and increased semen parameters after treatment as dependent variables, we constructed a multivariate linear regression model and identified statistically significant independent variables. RESULTS: After treatment, sperm concentration and the percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS) were obviously improved in both the DTP and microsurgery groups, with statistically significant difference between the two groups in sperm concentration and MNS, but not in PMS. Linear regression analysis showed that the severity of VC was an influencing factor for the recovery of sperm concentration after treatment in the DTP group (r = －11.599, Ra2 = 0.044 9) and the course of VC infertility was a factor affecting the recovery of sperm count in the microsurgery group (r = －1.837, Ra2 = 0.035 7). CONCLUSION: DTP is comparable to microsurgery in improving sperm motility while microsurgery is more effective in increasing the percentage of MNS in the treatment of VC-induced infertility. Early surgery is recommended for the treatment of infertility induced by severe bilateral VC, and DTP can be selected for infertility caused by mild or moderate bilateral VC if the patient is unwilling to accept surgery or microsurgery is inaccessible in the hospital.

[Danhong Tongjing Prescription improves sperm quality in patients with bilateral varicocele after varicocelectomy].

OBJECTIVE: To investigate the effect of Danhong Tongjing Prescription (DTP) on sperm quality in patients with bilateral varicocele (VC) after microsurgical varicocelectomy. METHODS: We randomly assigned 68 patients with bilateral VC to receive microsurgical varicocelectomy (the control group, n = 34) or microsurgical varicocelectomy followed by oral administration of DTP for a course of 90 days (the DTP group, n = 34). Before and after treatment, we obtained the sperm concentration, total sperm count, total sperm motility, the percentage of progressively motile sperm (PMS), sperm acrosomal enzyme activity, inhibin B (Inh-B) level, and sperm DNA fragmentation index (DFI) from the patients and compared the parameters between the two groups. RESULTS: There were no statistically significant differences in sperm concentration, PMS, acrosomal enzyme activity or sperm DFI among the patients with different degrees of VC preoperatively. After 3 months of medication, sperm concentration, total sperm count, total sperm motility, PMS and acrosomal enzyme activity were all increased while DFI decreased in both the control and DTP groups, even more significantly in the DTP group than in the control, and the Inh-B level was also markedly elevated in the DTP group in comparison with the baseline. CONCLUSIONS: The severity of bilateral VC is not correlated with the reduction of semen quality. DTP can improve sperm quality by improving total sperm count, PMS and acrosomal enzyme activity and reducing DFI in VC patients after varicocelectomy. The underlying mechanisms of the prescription may be related to its anti-oxidative stress action and abilities of improving reproductive hypoxia, spermatogenic environment and the function of Sertoli cells, but the specific signaling pathway involved is not yet clear.

Feasibility of local anaesthesia for varicocele correction in one-day-surgery setting. A single center experience.

OBJECTIVE: In this study, we compared postoperative outcomes of patients submitted to varicocele correction under general or local anesthesia at a single center. METHODS: All patients underwent varicocele surgical treatment with the Colpi-modified Marmar subinguinal technique. They were managed with either general (Group A) or local with ileo-inguinal and ileo-hypogastric nerves block (Group B) anesthesia. The two groups were compared in terms of timing of discharge and post-operative pain as assessed with the numeric rating scale (NRS) at both rest and movement (NRSm). § Results: Overall, 63 patients were included with a mean (SD) age of 25 years ± 5 yrs. The NRS mean score was significantly lower for Group B during the first 4 days after surgery at both rest and movement (all p < 0.05). Patients receiving local anesthesia showed a faster time to first urination (210 vs. 240 min; p = 0.02), although the time to discharge was comparable between the two groups (250 vs. 250 min). CONCLUSIONS: These results suggest that local anetshesia for varicocele surgical treatment is feasible and provide better pain control and faster recovery after surgery.

Assessment of seminal calcium and magnesium levels in infertile men with varicocele before and after varicocelectomy.

BACKGROUND: Trace elements perform a vital role in all stages of human physiology, as well as reproduction. OBJECTIVE: This study aimed to assess seminal calcium (Ca) and magnesium (Mg) in infertile men associated with varicocele (Vx). MATERIALS AND METHODS: Overall, 50 men were divided into two groups: fertile men (n = 20) and infertile men who were scheduled for Vx surgical repair (n = 30). Exclusion criteria were as follows: azoospermia, smoking, leukocytospermia, and consumption of Ca and/or Mg supplements. All cases were subjected to history taking and clinical examination. Semen analysis and assessment of seminal Ca and Mg by the colorimetric method were carried out for all cases at the base point and 3 months postvaricocelectomy. RESULTS: Generally, the mean seminal Ca and Mg levels demonstrated significant decreases in infertile men with Vx compared with the healthy fertile men linked to higher Vx grade as well as Vx bilaterality. These seminal decreases demonstrated significant increases after Vx surgical repair. Collectively, seminal Ca and Mg levels showed a significant positive correlation (r = 0.665, p= 0.001). Besides, seminal Ca, Mg levels, and Ca/Mg ratio showed significant positive correlation with sperm concentration (r = 0.479, p = 0.001; r = 0.541, p = 0.001; r = 0.282, p = 0.001, respectively), sperm motility percentage (r = 0.493, p = 0.001; r = 0.477, p = 0.001; r = 0.353, P = 0.001, respectively), and sperm normal forms percentage (r = 0.578, p = 0.001; r = 0.520, p = 0.001; r = 0.430, p = 0.001, respectively). DISCUSSION AND CONCLUSION: Seminal Ca and Mg levels and Ca/Mg ratio are significantly decreased in infertile men associated with Vx compared with fertile men with significant increases after varicocelectomy.

[Varicocelectomy combined with Qilin Pills for the treatment of varicocele-associated male infertility: A multi-center retrospective study].

OBJECTIVE: To investigate the effect of varicocelectomy (VCE) combined with medication of Qilin Pills (QLP) in the treatment of varicocele (VC)-associated male infertility. METHODS: We retrospectively analyzed the clinical data on 180 cases of VC-associated male infertility treated in our hospitals between October 2017 and March 2019, 67 by VCE ( the control group) and 113 by VCE in combination with 6-month medication of QLP after operation (the VCE+QLP group). We obtained the semen parameters from the patients before and at 1, 2, 3 and 6 months after surgery, measured their sperm DNA fragmentation index (DFI) before and at 6 months after operation, and recorded the rate of pregnancy at months postoperatively. RESULTS: There were no severe complications in any of the cases after surgery or during the whole course of medication. Compared with the baseline, the patients in control group showed significant increases at 6 months postoperatively in sperm concentration (ï¼»17.1 ± 12.4ï¼½ vs ï¼»29.5 ± 14.4ï¼½ ×106/ml, P < 0.01), sperm motility (ï¼»33.6±13.5ï¼½% vs ï¼»54.5±12.0ï¼½% , P <) and the percentage of progressively motile sperm (PMS) (ï¼»22.8 ± 10.9ï¼½% vs ï¼»43.7 ± 11.7ï¼½%, P <) but a remarkable decrease in sperm DFI (16.5 ± 7.6ï¼½% vs ï¼»13.3 ± 4.4ï¼½% , P <), and so did those in the VCE+QLP group in sperm concentration (ï¼»16.8 ± 10.7ï¼½ vs ï¼»38.9 ± 24.1)×106/ml, P < 0.01), sperm motility (ï¼»32.8 ± 14.0ï¼½% vs ï¼»50.1 ± 15.0)%, P <), PMS (ï¼»21.8 ± 11.3ï¼½% vs ï¼»39.6 ± 13.3ï¼½% , P <) and sperm DFI (ï¼»17.8 ± 9.0ï¼½% vs ï¼»11.8 ± 4.8ï¼½%, P <). There were even more statistically significant differences between the control and VCE+QLP groups at 6 months in the above semen parameters (P < 0.01) and in the rate of natural pregnancy (32.8% ï¼»22/67ï¼½ vs 48.7% ï¼»55/113ï¼½, P < 0.05). CONCLUSIONS: Varicocelectomy combined with medication of Qilin Pills can effectively improve semen quality and increase the rate of natural pregnancy in the treatment of VC-associated male infertility.

Alpha-lipoic acid improves sperm motility in infertile men after varicocelectomy: a triple-blind randomized controlled trial.

RESEARCH QUESTION: Does supplementation with alpha-lipoic acid (ALA) enhance sperm parameters and/or the status of sperm lipid peroxidation and DNA fragmentation in men who have undergone microsurgical repair of a varicocele? DESIGN: Individuals with a varicocele who had undergone varicocelectomy were divided into two groups receiving either 600 mg of ALA or an identical placebo for 80 days. Semen samples obtained from the participants before surgery and after completion of the course of medication were analysed and compared. Participants, clinicians and data analysts were blinded to the randomization sequence. RESULTS: In the ALA group, total motility (P = 0.01) and progressive motility (P = 0.002) of the spermatozoa were significantly higher compared with the placebo group after surgery. Sperm lipid peroxidation and DNA damage (assessed by sperm chromatin structure assay) showed significant decreases in both the ALA and placebo groups (P ≤ 0.02) after treatment. CONCLUSIONS: An 80-day course of ALA medication after surgical repair improves total motility and progressive motility of the spermatozoa in individuals with a varicocele.

L-carnitine as primary or adjuvant treatment in infertile patients with varicocele. A systematic review.

BACKGROUND: Varicocele has been found to impair the function of the epididymis resulting in subfertility whereas the varicocelectomy can resolve the phenomenon. L-carnitine is regarded as a biomarker for the function of the epididymis and has been found in reduced concentrations in infertile patients of various causes, including infertile men with varicocele. It seems that Lcarnitine and varicocele share clinical significance and the area of research looks promising. OBJECTIVE: To identify the role of L-carnitine in the treatment of varicocele. MATERIALS AND METHODS: A systematic search was performed in Pubmed/Medline with the terms (L-carnitine) and (varicocele) and (L-carnitine) and (varicocelectomy). Inclusion criteria were studies reported outcomes of L-carnitine administration alone or in duet, as primary or adjuvant treatment to varicocele. Exclusion criteria were non-English language and animal studies. Studies using L-carnitine as part of a panel of therapeutic agents were avoided. RESULTS: Only four suitable studies were identified for discussion. In one randomized study, the combination of L-carnitine and cinnoxicam improved semen parameters in patients with non-high-grade varicocele compared to L-carnitine alone and had a favourable effect on pregnancy rates but the effect of grade is unknown. In another study, as an adjuvant treatment to varicocelectomy, L-carnitine showed no clear benefit. Finally, in comparison to surgery, the results are inconclusive; two studies showed some benefit might be expected in low-grade or subclinical varicocele, but surgery appears superior. CONCLUSIONS: The evidence regarding the role of L-carnitine as a primary or adjuvant treatment of varicocele is sparse. The pathophysiological significance of L-carnitine implicates a potential role of the molecule in the management of varicocele, but the evidence so far is controversial for any recommendations. L-carnitine might be taken into consideration in selected cases; however, further search is needed in order the optimal role of L-carnitine in infertile patients with varicocele to be clarified.

Early and Synergistic Recovery Effect of Herbal Combination on Surgically Corrected Varicocele.

CONTEXT: Not all men presenting varicocele-associated infertility exhibit improved sperm quality or achieve pregnancy following varicocelectomy. Some combinations of specific natural herbs have been shown empirically to reduce oxidative stress and improve sperm quality. OBJECTIVE: We conducted a study to determine the effects of an herbal combination on sperm quality in varicocele-induced rats following varicocelectomy, hoping to find a new treatment approach to restore sperm quality following varicocelectomy. DESIGN: The research team designed an animal study. SETTING: The study took place in the Department of Urology at Seoul St. Mary's Hospital (Seoul, Republic of Korea). ANIMALS: Fifty white, male, Sprague-Dawley rats weighing 250 to 300 g each were used in the study. INTERVENTION: The rats were randomly assigned to 5 groups: (1) a control group (n = 10), (2) varicocele group (n = 10), (3) rats with varicocele and receiving varicocelectomy only (varicocelectomy group, n = 10), (4) rats with varicocele received varicocelectomy and oral administration with 200 mg/kg of an herbal combination for 4 wk (varicocelectomy + 200 mg/kg group, n = 10), and (5) rats with varicocele received varicocelectomy and oral administration with 400 mg/kg of an herbal com for 4 wk (varicocelectomy + 400 mg/kg group, n = 10). OUTCOME MEASURES: The study measured (1) sperm concentration and motility, (2) levels of reactive oxygen species (ROS), (3) concentrations of interleukin 6, interleukin 1ß, and tumor necrosis factor alpha (TNF-α), (4) apoptotic change, and (5) levels of heat shock protein (HSP). RESULTS: The sperm concentrations and motilities recovered after treatment in the varicocelectomy, varicocelectomy + 200 mg/kg, and varicocelectomy + 400 mg/kg groups. Significantly increased SOD and decreased ROS and cytokine levels were also observed. The apoptosis in the testes also was significantly decreased compared with the varicocele group. HSP70 in groups received varicocelectomy and administered with herbal combination was significantly decreased compared with the varicocelectomy group. CONCLUSIONS: The herbal combination was found to improve the sperm qualities, oxidative stress, and inflammation after varicocelectomy. Therefore, the herbal combination may provide a new and additional treatment for varicocele-associated infertility. For clinical application, further studies are needed to identify active ingredients in each herb and the mechanism by which each ingredient works, to standardize the herbal combination.

The role of Vitamin E - Selenium - Folic Acid Supplementation in Improving Sperm Parameters After Varicocelectomy: A Randomized Clinical Trial.

PURPOSE: In this study, we aimed to evaluate the effects of antioxidants including Vitamin E-Selenium-Folic acid (Vit E -Se- FA) on semen parameters following varicocelectomy (VCT). MATERIALS AND METHODS: Sixty patients from 64 infertile male patients diagnosed with varicocele (VC) who un-derwent sub-inguinal VCT were included in the study. Following sub-inguinal VCT, the patients were randomized into two groups: 30 receiving Vit E-Se-FA supplementation for six months, and 30 as the control group with supplemental treatment. The post-operative semen parameters of Vit E-Se-FA receiving group were compared with control group at the end of experiment. The sperm count, percentage of motile and abnormal sperms were considered. RESULTS: There were statistically significant differences in terms of count (P = .031) and motility (P = .01) of sperm after six months of receiving Vit E-Se-FA supplementation comparing with control group. CONCLUSION: Vit E-Se-FA supplementation can improve sperm parameters (count and motility of sperm) after VCT.

Melatonin therapy adds extra benefit to varicecelectomy in terms of sperm parameters, hormonal profile and total antioxidant capacity: A placebo-controlled, double-blind trial.

In this study, we aimed at investigating the impact of melatonin supplementation on semen parameters, hormonal profile and total antioxidant capacity after varicocelectomy. Infertile male patients who were diagnosed with varicocele and underwent subinguinal varicocelectomy were included in the study. After performing subinguinal varicocelectomy, the patients were randomised into two groups: 27 receiving melatonin for 3 months and 27 as the placebo-controlled group receiving placebo for 3 months. The pre-operative parameters of semen analyses, hormonal profile and seminal oxidative stress status of both groups were compared with those of post-operative parameters. There were statistically significant improvements in post-operative parameters of semen analyses (sperm concentration, motility and proportions of normally formed spermatozoa), peripheral blood inhibin B and total antioxidant capacity in melatonin group compared with placebo group. In conclusion, melatonin therapy adds extra benefit to varicecelectomy in terms of sperm parameters, peripheral blood inhibin B and total antioxidant capacity; however, further studies including large number of samples are needed to make a proper decision on melatonin supplementation after varicocelectomy.

Modified Inguinal Microscope-Assisted Varicocelectomy under Local Anesthesia: A Non-randomised Controlled Study of 3565 Cases.

Varicocele is a common abnormality, but the conventional microsurgical subinguinal varicocelectomy (CMSV) has some disadvantages. We invented Modified Inguinal Microscope-Assisted Varicocelectomy (MIMV) under local anesthesia. This study aims to evaluate MIMV by comparing it to CMSV in operating duration, time to return to normal activity, postoperative complications, achievement of natural pregnancy and improvement of semen quality for patients with infertility, pain score for those with scrotal pain, and so on. We enrolled 3089 patients who underwent MIMV and 476 who underwent CMSV in our hospital. Both the operating duration and the time to return to normal activity of MIMV was shorter than that of CMSV (P < 0.001). The recurrence rate (P < 0.001) and injury rate of vas deferens (P = 0.011) after MIMV were lower than that after CMSV. Moreover, patients with MIMV showed higher degree of satisfaction with the surgery experience and outcome than those with CMSV (P < 0.001). However, no statistical difference was found between the two groups in scores of pain due to surgery, postoperative varicose veins diameters, reflux duration, and the postoperative complications of wound infection, hydrocele, atrophy of testis, epididymitis, and scrotal hematoma. In summary, MIMV is a promising varicocelectomy and could be applied more in clinical practice.

Magnesium Sulfate Mediates Morphine Administration Reduction in Varicocelectomy Surgery.

AIMS: Varicocelectomy is the most common operation carried out by doctors for male infertility treatment. The aim of varicocele treatment is to hinder the refluxing venous drainage to the testis, retaining arterial inflow, and lymphatic drainage. A lot of pain is generated after this surgery, and the use of opium should be reduced to nearest minimum, as all drugs are toxins. Thus the aim of the present study is to facilitate morphine usage reduction after varicocelectomy surgery. MATERIAL AND METHODS: One-hundred (100) patients who were varicocelectomy candidate were randomized into two groups: experimental group contain 50 patients and control group contain 50 patients as well. In experimental group, 2 mL magnesium sulfate in 2 mL normal saline was injected into patient immediately after surgery. The control group received only 4 mL normal saline. Morphine dosage administered, and severity of pain monitoring was accessed and recorded with a visual analogue scale (VAS). RESULT: Result indicated that administration of morphine dosage in the test group 0.21 ± 0.64 mg was significantly lower as compared to the control group 0.75 ± 1.30 mg during the first 24-hour after surgery (p = 0.01). Average VAS scores in the experimental and control groups in the first 4-hour interval were 0.91 ± 1.30 and 2.9 ± 2.50 (p = 0.02) respectively. We observed a significant difference in the VAS score for pain severity and the dosages of morphine administered. CONCLUSIONS: The experimental group with magnesium sulfate in its drug formulation showed better pain control compared to the control group which received only normal saline, whose pain manifested after every few hours. This can be used for the formulation of opium for this surgery in a large scale.

[Adjuvant antioxidant therapy in varicocele infertility].

INTRODUCTION: Infertility affects an estimated 15% of couples globally. Male factor infertility accounts for about a half of infertility cases. About 40% of infertile men have varicocele. The aim of this study was to investigate the efficacy and safety of a complex of acetyl-L-carnitine, L-carnitine fumarate and alpha-lipoic acid (SpermActin-forte) (SA) for adjuvant antioxidant therapy after microsurgical varicocelectomy (MVE) in men with varicocele and assess its impact on the level of DNA fragmentation in sperm cells. MATERIALS AND METHODS: This is an open, prospective, randomized trial comprising 114 men aged 25-45 (mean 34.1+/-12.1) years who underwent MVE. The patients were allocated to receive either adjuvant SA (n=38), SA in combination with a vitamin complex (VC) (n=38) or no adjuvant therapy (n=38). The efficacy was assessed at 3 months by testing standard semen parameters and the level of sperm DNA fragmentation. RESULTS: MVE led to a 21.7% increase in the progressive sperm motility compared to the baseline level. In patients receiving SA, this was by 76.7% due to active sperm motility (category A) at 3 months. MVE with concurrent supplementation of SA resulted in a 22.3% decrease in the level of sperm DNA fragmentation at 3 months. When used in the postoperative period after MVE, SA and VC resulted in a 27% increase in the sperm concentration at 3 months. There were no side effects of pharmacotherapy. The statistical significance of the change in variables was calculated using the Wilcoxon test. Critical level =0.05 was established for all criteria. CONCLUSION: Using nutraceuticals (SA) after MVE is an effective and safe adjuvant antioxidant therapy of male infertility in patients with varicocele which leads to an improvement in the basic sperm parameters (sperm concentration and motility) and a decrease in the level of sperm DNA fragmentation in the short term. Adjuvant antioxidant therapy of varicocele infertility potentiates the effects of monotherapy (both medical and surgical), leads to an increase in its effectiveness and shortens the time to pregnancy. Further studies in this field are needed to assess long-term outcomes of the treatment.

Current and emerging therapies in premature ejaculation: Where we are coming from, where we are going.

Premature ejaculation is the most common form of sexual dysfunction among men. The pathophysiology of premature ejaculation appears to be multifactorial, implicating the need for multimodal therapeutic regimens to successfully treat premature ejaculation. Multiple treatment regimens have been shown to be effective in extending the time between penetration and ejaculation. These treatment modalities include everything from behavioral modifications and medications to diet alterations and major surgery. The goal of the present article was to review the commonly used treatment regimens used in the treatment of premature ejaculation, as well as to introduce and discuss the newest treatment routines under study for the treatment of premature ejaculation.

The impact of vitamin E supplementation on semen parameters and pregnancy rates after varicocelectomy: a randomised controlled study.

In this study, we aimed to investigate the impact of vitamin E supplementation on semen parameters and pregnancy after varicocelectomy. Forty-five infertile male patients who were diagnosed with varicocele and underwent subinguinal varicocelectomy were included in the study. After performing subinguinal varicocelectomy, the patients were randomised into two groups: 22 receiving vitamin E for 12 months, and 23 as the control group without receiving any supplementation. The pre-operative parameters of semen analyses and pregnancy rates of both groups were compared with those of post-operative parameters. There were no statistically significant differences between the groups in terms of sperm count and motile sperm percentage, in pre-operative, post-operative 3rd month, post-operative 6th month and post-operative 12th month periods. Repeated-measures anova was performed, and sperm count, percentage of change in sperm count, motile sperm count and percentage of change in motile sperm count of the groups were compared. The administration of vitamin E increased all of these parameters; however, they were not found to be statistically significant. In conclusion, vitamin E supplementation might improve the sperm parameters after varicocelectomy; however, further studies including larger number of samples are needed to make a proper decision on vitamin E supplementation after varicocelectomy.

Randomised clinical trial of comparing effects of acupuncture and varicocelectomy on sperm parameters in infertile varicocele patients.

The aim of the study was to evaluate the effect of the acupuncture treatment on sperm parameters and pregnancy rates in patients with primary infertility. Between January 2008 and May 2010, 30 men with the primary infertility (one year of unprotected intercourse, healthy wife) and varicocele with normal hormone levels and abnormal semen analysis were randomised into two groups. Group 1 underwent subinguinal microscopic varicocelectomy, and Group 2 underwent acupuncture treatment twice a week for 2 months. Both groups were evaluated with semen analysis at 6 months after the treatment. Patients in both groups evaluated with telephone calls and e-mail in terms of pregnancy. The mean age of the patients was 27.2, and groups were comparable regarding the age (P = 0.542). The pre-treatment sperm concentration, motility and morphological characteristics were similar in both groups. Sperm concentration and motility improved significantly in both groups after the treatment. Increase in sperm concentration was higher in the acupuncture group compared to the varicocelectomy group (P = 0.039). The average follow-up was 42 months, and pregnancy rates were emphasised 33% in both groups. Acupuncture treatment in primary infertile varicocele patients with semen abnormalities seems to be effective and has comparable results with the varicocelectomy treatment.

[Testicular artery-sparing microscopic varicocelectomy combined with Qilin Pills for bilateral varicocele-induced oligoasthenospermia].

OBJECTIVE: To explore the clinical effect of testicular artery-sparing microscopic varicocelectomy (MV) in combination with Qilin Pills (QL) in the treatment of bilateral varicocele-induced oligoasthenospermia. METHODS: Sixty patients with bilateral varicocele-induced oligoasthenospermia were randomly assigned to receive MV (n=30) or MV+QL (n=30), those in the latter group treated with oral QL for 12 weeks postoperatively. At 4, 8, and 12 weeks after operation, we compared the semen volume, sperm concentration, sperm motility, the levels of serum Inh B, luteinizing hormone (LH) and total testosterone (TT), and the testosterone secretion index (TSI) between the two groups. RESULTS: After surgery, all the patients showed disappearance of varicocele symptoms, remarkably improved semen volume, sperm concentration, sperm motility, serum Inh B and TT levels, TSI, decreased LH and FSH (P<0.01). At 12 weeks after treatment, statistically significant differences were found between the MV and MV+QL groups in Inh B (138.96±22.26 vs 129.54±22.23) ng/L, LH (3.17±0.12 vs 3.59±0.11) IU/L, TT (13.98±3.02 vs 12.68±3.12) nmol/L, and TSI (4.41±0.53 vs 3.53±0.51) nmol/ IU (P<0.05). The pregnancy rate was significantly higher in the MV+QL than in the MV group (73.4% vs 36.6%, P<0.05). CONCLUSIONS: Testicular artery-sparing microscopic varicocelectomy combined with Qilin Pills is an effective strategy for the treatment of bilateral varicocele-induced oligoasthenospermia by significantly improving the semen quality of the patient.

An integrated approach to male-factor subfertility: bridging the gap between fertility specialists trained in urology and gynaecology.

Subfertile men and women are usually cared for by different clinicians, namely urologists and gynaecologists. While these doctors share each other's goals, they may not always appreciate the content or implications of their opposite number's clinical decisions; to some degree they may practice in "silos." We address this problem by reviewing the effectiveness of medical treatments for male factor subfertility in the context of female factors. The effectiveness of treatments for couples with male factor subfertility, other than IVF with ICSI, appears modest. However, data from randomized controlled trials suggest benefits from some treatments: clomiphene and tamoxifen for the male (common odds ratio for pregnancy [COR] 2.42; 95% CI 1.47 to 3.94), antioxidants (COR 4.18; 95% CI 2.65 to 6.59) and surgical management of a clinical varicocele (COR 2.39; 95% CI 1.56 to 3.66). Nevertheless, close attention to female age and the duration of subfertility help to avoid lost opportunity through delays in treatment when IVF with ICSI is indicated. Making treatment decisions squarely in the context of the couple's overall prognosis is key for optimal outcomes. Future trials of male fertility treatments should focus on pregnancy as the primary outcome, rather than less important surrogates such as sperm quality.

Les hommes et les femmes hypofertiles obtiennent habituellement leurs soins auprès de cliniciens distincts, soit des urologues et des gynécologues, respectivement. Bien que ces professionnels de la santé aient des objectifs communs, il est possible qu'ils ne comprennent pas toujours le contenu ou les implications des décisions cliniques de leurs homologues; on pourrait même en venir à affirmer qu'ils agissent de façon cloisonnée. Nous traitons de ce problème en analysant l'efficacité des traitements médicaux visant l'hypofertilité masculine dans le contexte des facteurs féminins. À l'exception de l'utilisation concomitante de la FIV et de l'IICS, l'efficacité des traitements offerts aux couples qui font face à une hypofertilité attribuable à des causes imputables à l'homme semble modeste. Toutefois, des données issues d'essais comparatifs randomisés semblent indiquer que certains traitements offrent des avantages : clomiphène et tamoxifène administrés à l'homme (rapport de cotes commun pour ce qui est de la grossesse [RCC], 2,42; IC à 95 %, 1,47 - 3,94), antioxydants (RCC, 4,18; IC à 95 %, 2,65 - 6,59) et prise en charge chirurgicale d'une varicocèle clinique (RCC, 2,39; IC à 95 %, 1,56 - 3,66). Quoi qu'il en soit, le fait de bien porter attention à l'âge de la femme et à la durée de l'hypofertilité aide à éviter les occasions manquées en raison de délais dans la mise en œuvre du traitement, dans les cas où l'utilisation concomitante de la FIV et de l'IICS s'avère indiquée. Le fait de prendre des décisions en s'assurant de tenir absolument compte du pronostic global du couple est d'une importance capitale pour l'obtention d'issues optimales. L'obtention d'une grossesse (et non des critères auxiliaires moins importants, tels que la qualité des spermatozoïdes) devrait constituer le critère d'évaluation principal des futurs essais visant les traitements contre l'infertilité masculine.
