Objectives To assess the effectiveness and safety of carnitine in the treatment of idiopathic asthenozoospermia. Methods The Cochrane Library, MEDLINE, EMbase, and CNKI were searched between Jan 1995 and Dec 2006. Both English and Chinese studies were included in the review if they were randomized controlled trials (RCTs) involving men with idopathic asthenozoospermia who were treated with carnitine. Trial screening, data extraction, and quality assessment of included trials were conducted by method recommended by Cochrane Collaboration. Statistical analysis was conducted using RevMan 4.2.10 software. Results Five RCTs involving 346 patients met the inclusion criteria, and 307 patients were included in the meta-analysis. The results showed that: after being treated with carnitine for 3 and 6 months, the difference of the patients’ partners’ spontaneous pregnancy rate between treatment group and control group was statistically significant with RR2.46 and 95% CI1.12 to 5.43 (Z=2.23, P=0.03). After being treated with carnitine for 3 and 6 months, the difference of forward motile sperm per ejaculate between treatment group and control group was not statistically significant with WMD 9.16 and 95%CI 0.14 to 18.18 (Z=1.99, P=0.05) and WMD 5.28 and 95%CI –4.45 to 15.01 (Z=1.06, P=0.29). After being treated with carnitine for 3 and 6 months, the difference of percentage of forward sperm motility between treatment group and control group was not statistically significant with WMD 14.56 and 95%CI –4.49 to 33.61( Z=1.50 ,P=0.13), and WMD 7.34 and 95%CI –5.93 to 20.61 (Z=1.08, P=0.28). After being treated with carnitine for 3 and 6 months, the difference of total motile sperm per ejaculate between treatment group and control group was not statistically significant with WMD 15.32 and 95%CI –1.34 to 31.98 (Z=1.80, P=0.07) and WMD 6.20, 95%CI –3.00 to 15.39 (Z=1.32, P=0.19).After being treated with carnitine for 3 and 6 months, the difference of percentage of total sperm motility between treatment group and control group was not statistically significant with WMD 2.97 and 95%CI –5.75 to 11.69 (Z=0.67, P=0.50) and WMD 4.48 and 95%CI-9.17 to18.14 (Z=0.64, P=0.52). After being treated with carnitine for 3 and 6 months, the difference of semen volume between treatment group and control group was not statistically significant with WMD –0.12 and 95%CI –0.55 to 0.30 (Z=0.57, P=0.57) and WMD 0.03 and 95%CI –0.38 to 0.45 (Z=0.16, P=0.87). After being treated with carnitine for 3 and 6 months, the difference of sperm concentration between treatment group and control group was not statistically significant with WMD 7.92 and 95%CI – 2.85 to18.68 (Z=1.44, P=0.15), and WMD 1.02 and 95%CI –5.09 to 7.14 (Z=0.33, P=0.74). Three RCTs reported that there were no serious side effects of carnitine during the treatment period. Conclusions The available evidence indicates that spontaneous pregnancy rate would increase with carnitine therapy, while it is short of improvement of semen parameters. There is no serious side effect of carnitine. Because of lack of evidence, we cannot conclude that carnitine is effective in improving the prognosis of infertile patients with idiopathic asthenozoospermia. More high quality trials with large sample are proposed.

Methods Eighty infertility patients with the facilitating ovulation treatment were included from August 2004 to May 2008. Ovulation monitoring was based on the level of estrogen and luteinizing hormone, transvaginal B ultrasound, the cervical Inlser score and assay of basal body temperature. Besides, adverse reactions were observed. Results The rates of ovulation of clomiphene and human menopausal gonadotropin were 77.3% and 85.6%. The rate of ovarian hyperstimulation syndrome (OHSS), which was mostly caused by human menopausal gonadotropin with 150 IU, was 150%. The rate of luteinized unruptured follicle syndrome (LUFS) was 90%. Conclusion Individual therapy with human menopausal gonadotropin and clomiphene is essential to infertility patients with ovulation barrier. The efficacy of human menopausal gonadotropin and clomiphene is relevant to the ovarian condition and the hormone levels. Individual using of hormone is important in the facilitating ovulation treatment, which is helpful to increase the effective efficacy and prevent the OHSS.
Objective To assess the effectiveness and safety of traditional Chinese medicinal herbs for subfertility. Method Databases used including MEDLINE, EMBASE, CBM and the Cochrane Controlled Trial Register (CCTR). Potentially related trials in reference lists of studies were hand searched. Published RCTs in any languages and length whether they were blind or unblind, were included. Treatments were Chinese medicinal herbs (single or compound), and controls were placebo, standard medical intervention, or no intervention. Data were extracted independently by two reviewers and analyzed with Revman 4.2 softeware. Results 7 randomized trials, including 1 042 patients met inclusion criteria. Methodological quality of all trials was poor. Chinese medicinal herbs were effective compared with routine antibiotics [RR 1.49, 95％CI (1.37 to1.62), Plt;0.000 01] and resulted in higher pregnancy rate [RR 1.46, 95%CI (1.09 to,1.96), P=0.01]. There were no adverse events reported in treatment group. Conclusions Some Chinese medicinal herbs may be effective for subfertility. However, the evidence is too weak to draw a conclusion. More strictly designed, randomized, double-blind, placebo-controlled trials are required.
ObjectiveTo investigate the effect of laparoscopic surgery combined with the following treatment of gonadotropin-releasing hormone agonist (GnRH-a) on the patients with endometriotic infertility and the value of endometriosis fertility index (EFI) system on forecasting the pregnancy outcome. MethodsFrom January 2005 to July 2011, the clinical data of 15 patients with endometriotic infertility patients were analyzed retrospectively. All the patients underwent laparoscopic surgery, and the effect was evaluated according to the endometriosis fertility index (EFI). Then all the patients were divided randomly into two groups on the basis of the different assisted treatment after the laparoscopic surgery:the control group (without any other therapy) and the GnRh-a group (combined with GnRH-a). Eventually, the pregnant rates were calculated respectively in the different groups or according to the different EFI. ResultsAt last, 103 cases finished the follow-up. The pregnancy rate in the control group after 6 months, 1 year and 3 years therapy were 12.5%, 31.2%, and 41.7%, respectively; while in the GnRh-a group were 0%, 16.3%, and 40.0%, respectively. There were no difference between the two groups after the 1 year and 3 years therapy (P>0.05). Besides, all of the 55 cases in the GnRh-a group had side-effects, but no severe adverse effect was encountered. All the side-effects were disappeared after stopping the treatment. The pregnancy rate of the patients with the EFI score of 8-10 was respectively 31.3% 1 year and 62.5% 3 years after the treatment. However, the pregnancy rate of the patients with the EFI score of 5-7 was respectively 15.2% 1 year and 26.0% 3 years after the treatment. There were only 9 patients with the EFI score of 0-4, and all of them were not pregnant. The EFI score had positive correlation with the pregnancy rate 1 year and 3 years after the treatment (rs=0.204, P=0.039; rs=0.437, P<0.001). ConclusionThe treatment of GnRh-a after the laparoscopic surgery can not only increase the rate of the pregnancy, but also delay the pregnancy occasion and increase the occurrence of the side-effects. The EFI may be valuable for forecasting the rate of pregnancy in patients with endometriotic infertility. The patients with EFI score higher than 8 may expect the pregnancy, while the ones with below 7 probably have much lower rate of natural pregnancy rate.
Objective To assess the effectiveness and safety of Chinese medicinal herbs for female immune-caused subfertility. Methods Databases included: MEDLINE (1966-2002.2), EMBASE (1984-2002.2), CBM (1978-2002.2) and Cochrane Controlled Trial Register, CCTR (Issue 1, 2002). Reference lists of trials were handsearched. Published randomized controlled trials (RCTs) whether blind or unblind, any languages and length of follow up were included. Treatments included Chinese medicinal herbs (single or compound). Controls were placebo and western medicine, or no intervention. Data were extracted independently by two reviewers and analyzed with Revman 4.2. Results Six RCTs were included, all of which were poor in methodological quality. Because of different therapies in the treatment and control groups, we did not perform meta-analysis. The No.1 anti-immune tablet was more effective than corticosteroid plus condom during intercourse both in the pregnancy rate (RR 3.75, 95%CI 1.61 to 8.75, P=0.002) and AsAb negative rate (RR 1.66, 95%CI 1.23 to 2.22, P=0.000 8). Bushen Xiezhuo Soup was more effective than antibiotic in the pregnancy rate (RR 2.97, 95%CI 1.60 to 5.50, P=0.000 6) and antisperm antibody (AsAb) negative rate (RR 2.33, 95%CI 1.54 to 3.54, Plt;0.000 1)。Zhenqi Zhuanyin Soup was as effective as IUI in pregnancy rate (RR 1.80, 95%CI 0.58 to 5.60, P＝0.31) but more effective than IUI in AsAb negative conversion rate (RR 9.61, 95%CI 3.22 to 28.67, Plt;0.000 1), Zhenqi Zhuanyin Soup combined with IUI was more effective than IUI in pregnancy rate (RR 3.60, 95%CI 1.32 to 9.85,P=0.01) and AsAb negative rate (RR 8.92, 95%CI 2.98 to 26.75, Plt;0.000 1). Conclusions Some Chinese medicinal herbs may work well in subfertility treatment. However, the evidence is too weak to draw a conclusion for there are deficiencies in strict randomization, blinding and follow-up.More strictly designed, randomized, double-blind, placebo-controlled trials are required.

Objective To employ Mendelian randomization (MR) to assess the potential causal relationship between 15 micronutrients in serum and male infertility, so as to provide a scientific basis for the etiological prevention of male infertility. Methods Male infertility was taken as the outcome variable, and 15 serum micronutrients was regarded as the potential influencing factors. A two-sample MR analysis was conducted using genome-wide association study with the European population. Multivariable MR analysis was employed to explore the independent effects of potential micronutrients on male infertility. Results A total of 198 single nucleotide polymorphisms across 15 groups were included as instrumental variables to assess the causal association between micronutrients and male infertility. Univariate analysis showed that increased serum iron levels were positively causally associated with a higher risk of male infertility (odds ratio=2.917, P=0.015). Besides, multivariate MR analysis suggested that this positive causal relationship between iron and male infertility remains significant (odds ratio=3.253, P=0.029). Meanwhile, this study found a negative association between elevated vitamin D levels and the risk of male infertility (odds ratio=0.403, P=0.020).Conclusion Elevated serum iron levels and increased vitamin D levels are associated with significant positive and negative causal effects on male infertility, respectively.
ObjectiveTo systematically review the efficacy of acupuncture for PCOS infertility.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect randomized controlled trials (RCTs) of acupuncture for PCOS infertility from inception to January 5th, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 28 RCTs involving 2 192 patients were included. The results of meta-analysis showed that compared with western medicine alone, acupuncture could increase the pregnancy rate (RR=1.80, 95%CI 1.45 to 2.23, P<0.000 01) and ovulation rate (RR=1.33, 95%CI 1.15 to 1.54, P=0.000 1), and reduce levels of LH (SMD=?0.62, 95%CI ?0.96 to ?0.28, P=0.000 4) and LH/FSH (SMD=?0.65, 95%CI ?1.02 to ?0.29, P=0.000 5). Acupuncture combined with western medicine could increase the pregnancy rate (RR=1.75, 95% CI 1.50 to 2.03, P<0.000 01) and ovulation rate (RR=1.29, 95%CI 1.18 to 1.41, P<0.000 01), decrease levels of LH (SMD=?1.09, 95%CI ?1.64 to ?0.53, P=0.000 1), LH/FSH (SMD=?1.30, 95%CI ?2.35 to ?0.25, P=0.02), and levels of T (SMD=?1.13, 95%CI ?1.59 to ?0.66, P<0.000 01).ConclusionsCurrent evidence shows that acupuncture alone or combined with western medicine can significantly improve ovulation rate, pregnancy rate and reduce hormone level. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To investigate the application of hysteroscopy in pathological changes of infertility uterus. Methods The clinical data of 226 cases of infertility females receiving hysteroscopy from January 2007 to June 2009 in Sichuan Provincial Hospital for Women and Children were retrospectively analyzed. Results In 226 cases, hysteroscopic examination identified 147 cases of intrauterine diseases (65.04%), including 56 cases of intrauterine adhesion (24.78%), 32 cases of endometritis (14.16%), 27 cases of endometrial polyps (11.94%), 15 cases of uterine malformation (6.64%), 9 cases of submucous myoma (3.98%), 3 cases of endometrial tuberculosis (1.33%), 3 cases of uterus cavity narrow (1.33%), 2 cases of cervical internal relaxation (0.88%). No postoperative complications occurred, except for a small amount of vaginal bleeding. Conclusion For the diagnosis of the pathological changes in uterus, hysteroscopy is a direct and accurate method with less operative duration, less trauma, less pain, quick recovery, no complications, and no necessity for hospitalization.
