The vaginal microbiota is a complex and dynamic environment that plays an important role in the healthy reproduction of women. The mechanism of unexplained infertility is not yet clear, and the imbalance and low stability of vaginal microbiota may be related to unexplained infertility. Taking probiotic composite preparations to restore normal vaginal microbiota may be a safe and natural method for treating unexplained infertility. This article reviews the probiotic composite preparations used in the treatment of unexplained infertility both domestically and internationally, including the isolation site of the bacterial species, the use method of the composite preparation, the course of treatment, and the final therapeutic effect, aiming to provide a basis for the clinical application of probiotic composite preparations in the treatment of unexplained infertility.

OBJECTIVETo investigate the status of the semen of the infertility patients infected by Gardnerella vaginalis (Gv).

METHODSSemen samples from 373 clinic patients of infertility and vaginal samples from 63 positive patients' wives were collected from April 2002 to May 2003. And the samples were tested by nested polymerase chain reaction (nPCR).

RESULTSThe positive rate of the infertile males' semen infected by Gv was 44.2%, while that of the postive patients' wives was 87.3%.

CONCLUSIONThe positive rate of the infertile male's semen infected by Gv is high and Gv can be spread by sexual intercourse.

OBJECTIVETo investigate the influence of Ureaplasma urealyticum (Uu) infection in the male reproductive tract on the outcomes of IVF and the clinical significance of preoperative Uu test by analyzing the correlation between the results of Uu culture before IVF-ET and the outcomes of IVF-ET.

METHODSAmong 1,059 couples undergoing IVF-ET, we selected 973 after excluding genetic factors and divided them into a Uu negative and a Uu positive group according to the results of culture of Uu in the semen of the males. We compared the rates of IVF fertilization, oocyte cleavage, clinical pregnancy and abortion between the two groups, and analyzed the influence of Uu infection on IVF outcomes.

RESULTSAmong the 973 selected subjects, 836 were Uu negative (group A) and 137 Uu positive (group B), and of the latter, 130 were restored to Uu negative after treatment (group B1) and the other 7 remained unchanged (group B2). No significant differences were found between groups A and B in the rates of IVF fertilization (81.6% vs 79.8%, P = 0.13), abnormal fertilization (11.8% vs 12.4%, P = 0.58) and oocyte cleavage (92.0% vs 92.1%, P = 0.94), nor between groups A and B2 (81.6% vs 89.8%, P = 0.10; 11.8% vs 13.2%, P = 0.75; 92.0% vs 92.5%, P = 0.10). Totally, 747 of the patients underwent embryo transfer, including 643 in group A and 104 in group B. There were no significant differences between groups A and B in the rates of clinical pregnancy (38.6% vs 34.7%, P = 0.44) and abortion (16.5% vs 22.2%, P = 0.39), nor between groups A and B2 (38.6% vs 33.3%, P = 0.79; 16.5% vs 0, P = 0.53).

CONCLUSIONUu infection in the male reproductive tract does not significantly affect the rates of IVF fertilization, oocyte cleavage, clinical pregnancy and abortion. However, more investigations with larger sample sizes of the cases restored from Uu positive to Uu negative are needed to lend further support to our findings.

OBJECTIVEDiscussion of the relationship between Mycoplasma and chlamydia infection and lesions in the cervical tissue in high-risk HPV-positive infertile patients with cervical.

METHODSHPV-negative patients with cervical as the control, retrospective analysis the relationship of Mycoplasma hominis and chlamydia infection, cervical histological graded, and inflammation graded.

RESULTSThe rate of HPV infection in mycoplasma-positive and those with negative mycoplasma has significant difference (P < 0.01), The rate of HPV infection in chlamydia-positive and those with negative chlamydia has no significant difference (P > 0.05). CIN and the incidence of cervical erosion and CIN grade were higher in HPV-positive than HPV-negative group (P < 0.01). The cervical erosion of HPV-positive was no difference in the degree (P > 0.05). Compared with the simple HPV-positive group, CIN and the incidence of severe cervical erosion in mixed infection of Mycoplasma was no difference (P > 0.05).

CONCLUSIONMycoplasma infection increases the rate of high risk HPV infection, high-risk HPV infection increased cervical pathological damage, Mycoplasma infection might be the factor of persistent infection with high risk HPV, the degree of cervical pathological is the factor of cervical infertility which can not be ignored.

OBJECTIVETo explore the effects of mycoplasma and chlamydia infections on tubal infertilityand to assess the antibiotic susceptibility and resistance of female urogenital, and consequently to guide clinical rational drug use.

METHODS327 tubal infertility women as infertility group and 286 healthy pregnant women as control group were randomly selected, detected chlamydia trachomatis (CT), ureaplasma urealyticum (UU) and mycoplasma hominis (MH) in cervical secretions and drug resistance of UU and MH.

RESULTSCT infection rates (14.99%), UU infection rates (23.24%), UU + MH infection rates (29.05%),CT + UU + MH infection rates (9.17%) and total infection rates (88.99%) in infertility group is higher than those (order: 2.80%, 6.99%, 8.39%, 4.55%, 29.02%) in the control group, comparisons of two groups are statistically significant differences (P < 0.05), the susceptibility of UU to roxithromycin (sensitivity is 96.05%), josamycin (sensitivity is 96.05%), tetracycline (sensitivity is 82.89%), vibramycin( sensitivity is 92.11%) and clarithromycin (sensitivity is 96.05%) were relatively high and low to ciprofloxacin and acetyl spiramycin. The susceptibility of MH to josamycin (sensitivity is 95.83%), vibramycin (sensitivity is 91.67%), minocin (sensitivity is 83.33%) and actinospectacin (sensitivity is 75.00%) were relatively high and low to erythromycin, azithromycin, roxithromycin and clarithromycin. UU + MH was only sensitive to josamycin (sensitivity is 90.52%), high resistance (77.89% -91.58%) to erythromycin, azithromycin, acetyl spiramycin, ciprofloxacin, ofloxacin, azithromycin and clarithromycin.

CONCLUSIONInfection of CT, UU, MH and tubal infertility have certain relevance,the rates of CT, UU and MH infection in tubal infertility patients higher than fertile people. For many commonantibacterial drugs, UU, MH and UU + MH has strong resistance, the etiology detection and using adapted antibios should be taken seriously in clinical treatment.

AIMTo evaluate the association between selected potential socio-demographic and behavioral risk factors and infertility in Nigerian men.

METHODSThere were two groups in this study. One group consisted of 150 men with proven male infertility, and the other consisted of 150 fertile men with normal semen parameters. Both were matched for age, place of residence and key socio-demographic variables. They were compared for sexual history, past medical and surgical history, past exposures to sexually transmitted infections and treatment, past and current use of drugs as well as smoking and alcohol intake history.

RESULTSInfertile men were significantly more likely than fertile men to report having experienced penile discharge, painful micturition and genital ulcers, less likely to seek treatment for these symptoms and more likely to seek treatment with informal sector providers. Multivariate analysis showed that male infertility was significantly associated with bacteria in semen cultures, self-reporting of previous use of traditional medications and moderate to heavy alcohol intake, but not with smoking and occupational types.

CONCLUSIONINFERTILITY is associated with various proxies of sexually transmitted infections (STIs) and poor healthcare-seeking behavior for STIs in Nigerian men.
