Methods: A prospective, case-control study was conducted in which 430 men were enrolled. All the men had sought their first infertility evaluation between 1998-2002 in the State Research Center on Maternal Child Health, Ulaanbaatar, Mongolia. They were divided into two groups depending on the results of their semen analysis: 191 with abnormal semen and 239 with normal semen profile. Univariate and multivariate analyses were performed to determine any association between risk factors and semen abnormality. Results: Logistic regression analysis demonstrated that the testicular volume, a history of sexually transmitted infections (STI), epididymitis and testicular damage all have statistically significant associations with semen abnormality, when controlled for multiple risk factors. Adjusted odds ratios of 3.4 for mumps orchitis, 2.3 for other orchitis and 3.9 for testicular injury were found. Gonorrhoea, the most commonly reported STIs in this study, gave an adjusted odds ratio of 1.0 for having one or more sperm abnormality. An adjusted odds ratio for subjects with a history of other STIs was 2.7. However, as a predictor of azoospermia, STIs had very high odds ratio, being 5.6 in patients with gonorrhoea and 7.6 in patients with other STIs. Conclusion: A history of pathology involving testicular damage appeared to have the strongest impact on male infertility in Mongolia. STIs have less impact on semen quality except when complicated by orchitis, epididymitis and vasal obstruction.展开更多

Objec...Background: Intrauterine adhesion is a clinical entity that may present with subfertility. However, outcome of management depends on severity of intrauterine adhesion and type of treatment intervention employed. Objective: To evaluate clinical and investigative correlation of etiologic risk factors of intrauterine adhesion on fertility and pregnancy outcome following treatment. Patients and Methods: A 5 years prospective observational study. Treatment employed includes transvaginal blind intrauterine adhesiolysis, insertion of inert intrauterine device or inflated Foley’s catheter balloon and oestrogen therapy. Inclusion criteria are intrauterine adhesion as the only identifiable cause of infertility and post treatment follows up for at least a year. Results: Over a period of 5 years, 63 patients with mean age of 31.6 years and age range of 21 to 42 years were managed. Etiologic risk factors were dilatation and curettage 33 (52.4%), vacuum aspiration 13 (20.6%), myomectomy 11 (17.5%) and caesarean section in 6 (9.5%) patients. Of the 63 patients, 28 conceived giving a pregnancy rate of 44.4%. Nine out of the 28 patients that conceived had miscarriage, giving a miscarriage rate of 32.1%. The highest pregnancy rate and lowest miscarriage rate were recorded in the subgroup that had vacuum aspiration as their etiologic risk factor. Late pregnancy complications encountered are preterm contractions 5 (26.3%), placenta praevia 4 (21.1%), morbidly adherent placenta 5 (26.3%) and preterm delivery in 2 (10.5%) patients. Route of delivery was per vaginum in 13 (68.4%) patients and by caesarean section in 6 (31.6%) patients. Live birth rate was 89.5% (17/19 deliveries). There was no maternal mortality recorded. Conclusion: Compared to other risk factors, uterine vacuum aspiration was associated with higher fertility rate and better pregnancy outcome.展开更多

Methods: There 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. Results: Infertile 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. Conclusion: Infertility is associated with various proxies of sexually transmitted infections (STIs) and poor healthcare-seeking behavior for STIs in Nigerian men.展开更多

Objectives: The study aimed to determine types of infertility and their contributing factors among the respondent infertile women. Methods: This prospective cross-sectional study was conducted among infertile women visiting Sir Salimullah Medical College and Hospital, Dhaka. From January to December 2020, 111 infertile women were included and evaluated for infertility types and their contributing factors. Data were collected by face-to-face interviewing, and data were analyzed statistically. Results: Primary infertility was found among 90 (81%) and secondary infertility among 21 (18.9%). Among the direct risk factors of female infertility, ovulation failure was the majority of the cases, 74 (35.1%), and its mainly observed in primarily infertile women 58 (33.9%). These observations were statistically significant. Conclusions: Infertility should be treated as a public health problem, government and non-government organizations should develop a basic policy to create effective fertility centers.展开更多

ICSI is done for reasons other than male factor infertility, and on the whole has not been shown to have any more negative effects than those seen with IVF. There have however, been very few studies of ICSI with a focus on, or large enough numbers to examine, the specific outcomes associated with male factor infertility. From the limited information available in relation to the source of the sperm and aetiology of infertility in the presence of ICSI, there appears to be no increased risk of congenital malformations. There is, however, a small increase in both de novoand inherited chromosome abnormalities. In terms of growth and neurodevelopment, there are very few studies, and so far, no adverse outcomes have been found in young children whose fathers have a sperm defect. The origin of the sperm used in ICSI does not have a major influence on the early life outcomes for the offspring, but transgenerational and epigenetic effects remain unknown. When the male factor infertility is known or thought to be due to a Y-chromosome deletion, this information should be given to the young male offspring at a time that will ensure his own reproductive health and plans are optimized.展开更多

Methods: In total, 178 infertile patients with azoospermia (nonobstructed), 134 infertile patients with oligozoospermia as well as 40 fertile man controls were included in the present study. The samples were screened for AZF microdeletion using optimized multi-analyte suspension array (MASA) technology. Results: Of the 312 patients, 36 (11.5%) were found to have deletions in the AZF region. The rnicrodeletion frequency was 14% (25/178) in the azoospermia group and 8.2% (11/134) in the oligospermia group. Among 36 patients with microdeletions, 19 had deletions in the AZFc region, seven had deletions in AZFa and six had deletions in AZFb. In addition, four patients had both AZFb and AZFc deletions. No deletion in the AZF region was found in the 40 fertile controls. Conclusion: There is a high prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. The MASA technology, which has been established in the present study, provides a sensitive and high-throughput method for detecting the deletion of the Y chromosome. And the results suggest that genetic screening should be advised to infertile men before starting assisted reproductive treatments.展开更多

A literature review was undertaken to explore the societal constructs informing perspectives of childbearing, family planning and infertility, alongside Chinese considerations of fertility treatments, including assisted reproductive technologies and fertility counselling. In China, childbearing attitudes and behaviours are shaped by tensions between traditional cultural values of the filial piety originating from Confucianism, the history of strict family planning policy, the recent termination of one-child policy and the socioeconomic circumstance. For infertile Chinese individuals, the inability to meet these childbearing expectations gives rise to significant pressure and consequent psychological distress, particularly depressive symptoms. Demographic factors such as gender, education, income and geographical location have been found to influence prevalence and degree of depression in infertile Chinese men and women. These difficulties are compounded by barriers of cultural acceptance, legislative restrictions and availability of resources for alternative options such as adoption and surrogacy. It is important that these fertility sociocultural factors are taken into consideration when assisting Chinese patients to access and utilise fertility treatment services.展开更多

The majority of the population is affected by this disorder caused by male factor infertility(1); but the etiologies are still unknown. After the primary genetic structure in infertile phenotypes is searched, an evaluation can be made. Thus the reasons causing infertility can be discovered and patients can benefit from effective therapies(1). Publications about male infertility within the recent 10 years in the Pubmed database were discussed(1). There are some approachments for describing the function of specificgenes, but no adequate study is present to be useful for diagnosing and treating male infertility(1). Male fertility and fertility in offspring of males are considerably affected by the exact transition of epigenetic information(1). When the genetic factors playing a role in male infertility were analysed, significant steps will be taken for treating patients and determining the reasons of idiopathic infertility(1). Developments in technology associated with the impact of genetics may enable to specify the etiology of male infertility by determining specific infertile phenotype marks(1).展开更多

文摘Aim: To determine the most common risk factors of male infertility in Mongolian men attending an infertility clinic. Methods: A prospective, case-control study was conducted in which 430 men were enrolled. All the men had sought their first infertility evaluation between 1998-2002 in the State Research Center on Maternal Child Health, Ulaanbaatar, Mongolia. They were divided into two groups depending on the results of their semen analysis: 191 with abnormal semen and 239 with normal semen profile. Univariate and multivariate analyses were performed to determine any association between risk factors and semen abnormality. Results: Logistic regression analysis demonstrated that the testicular volume, a history of sexually transmitted infections (STI), epididymitis and testicular damage all have statistically significant associations with semen abnormality, when controlled for multiple risk factors. Adjusted odds ratios of 3.4 for mumps orchitis, 2.3 for other orchitis and 3.9 for testicular injury were found. Gonorrhoea, the most commonly reported STIs in this study, gave an adjusted odds ratio of 1.0 for having one or more sperm abnormality. An adjusted odds ratio for subjects with a history of other STIs was 2.7. However, as a predictor of azoospermia, STIs had very high odds ratio, being 5.6 in patients with gonorrhoea and 7.6 in patients with other STIs. Conclusion: A history of pathology involving testicular damage appeared to have the strongest impact on male infertility in Mongolia. STIs have less impact on semen quality except when complicated by orchitis, epididymitis and vasal obstruction.
文摘Background: Intrauterine adhesion is a clinical entity that may present with subfertility. However, outcome of management depends on severity of intrauterine adhesion and type of treatment intervention employed. Objective: To evaluate clinical and investigative correlation of etiologic risk factors of intrauterine adhesion on fertility and pregnancy outcome following treatment. Patients and Methods: A 5 years prospective observational study. Treatment employed includes transvaginal blind intrauterine adhesiolysis, insertion of inert intrauterine device or inflated Foley’s catheter balloon and oestrogen therapy. Inclusion criteria are intrauterine adhesion as the only identifiable cause of infertility and post treatment follows up for at least a year. Results: Over a period of 5 years, 63 patients with mean age of 31.6 years and age range of 21 to 42 years were managed. Etiologic risk factors were dilatation and curettage 33 (52.4%), vacuum aspiration 13 (20.6%), myomectomy 11 (17.5%) and caesarean section in 6 (9.5%) patients. Of the 63 patients, 28 conceived giving a pregnancy rate of 44.4%. Nine out of the 28 patients that conceived had miscarriage, giving a miscarriage rate of 32.1%. The highest pregnancy rate and lowest miscarriage rate were recorded in the subgroup that had vacuum aspiration as their etiologic risk factor. Late pregnancy complications encountered are preterm contractions 5 (26.3%), placenta praevia 4 (21.1%), morbidly adherent placenta 5 (26.3%) and preterm delivery in 2 (10.5%) patients. Route of delivery was per vaginum in 13 (68.4%) patients and by caesarean section in 6 (31.6%) patients. Live birth rate was 89.5% (17/19 deliveries). There was no maternal mortality recorded. Conclusion: Compared to other risk factors, uterine vacuum aspiration was associated with higher fertility rate and better pregnancy outcome.

文摘Objectives:To investigate the effect of Chinese herbal medicine"heche assisted preg-nancy recipe (HCAPR)" on estrogen receptor(ER), progesterone receptor (PR), pro-lifierating cell nuclear antigen(PCNA) and vascular endothelial growth factor (VEGF)in endometrium of infertile women.Methods: The S-P immunohistochemical assay was used to observe expression ofER, PR , PCNA and VEGF in late proliferative phase before and after the HCAPR treat-ment.Results: After the treatment, the expression of ER,PR,PCNA and VEGF in nucleiof glandular epithelium and stromal cells was significantly stronger (all P<0. 001) re-spectively than that before treatment , especially the expression of PCNA and VEGF.Conclusions: These results suggest that traditional Chinese medicine HCAPR oftonifying kidney and regulating menstruation increased the synthesis of ER,PR, PCNAand VEGF, which may promote normal growth and development of the endometrium ,improve the micro-environment of the endometrium, and enhance uterine receptivity.The evidence may provide theoretical basis for therapy infertility with Chinese herbalmedicine.
文摘Aim: To develop a high-throughput multiplex, fast and simple assay to scan azoospermia factor (AZF) region microdeletions on the Y chromosome and establish the prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. Methods: In total, 178 infertile patients with azoospermia (nonobstructed), 134 infertile patients with oligozoospermia as well as 40 fertile man controls were included in the present study. The samples were screened for AZF microdeletion using optimized multi-analyte suspension array (MASA) technology. Results: Of the 312 patients, 36 (11.5%) were found to have deletions in the AZF region. The rnicrodeletion frequency was 14% (25/178) in the azoospermia group and 8.2% (11/134) in the oligospermia group. Among 36 patients with microdeletions, 19 had deletions in the AZFc region, seven had deletions in AZFa and six had deletions in AZFb. In addition, four patients had both AZFb and AZFc deletions. No deletion in the AZF region was found in the 40 fertile controls. Conclusion: There is a high prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. The MASA technology, which has been established in the present study, provides a sensitive and high-throughput method for detecting the deletion of the Y chromosome. And the results suggest that genetic screening should be advised to infertile men before starting assisted reproductive treatments.

文摘Objective:To translate the English version of Infertility Self-Efficacy Scale into Chinese and to validate the psychometric properties of the Chinese version of the Infertility Self-Efficacy Scale(CISE).Method(s):Participants were recruited from the Gynecology Department of two city hospitals.Five main processes were involved in the formation of CISE[1]:scale translation based on expert consultation[2];pre-test questionnaire development with infertile women's feedback(N=20)[3];factor structure assessed by exploratory and confirmatory factor analysis(N=177)[4];assessment of reliability by internal consistency(N=177)and test-retest reliability(N=21);and[5]assessment of convergent validity with Self-rating Anxiety Scale,Self-rating Depression Scale,and Simplified Coping Style Questionnaire(N=177).Results:This study established a 16-item CISE.Factor analyses confirmed a onecomponent solution,which explained 54.59% of total variances and showed an acceptable model fit.Cronbach's a and test-retest correlation coefficients for the scale were 0.94 and 0.84,respectively.The CISE score was significantly correlated with anxiety(r=0.47),depression(r=0.60),positive coping style(r=0.37),and certain negative coping style items.Conclusion:This 16-item CISE is a reliable and valid measure to evaluate perceived selfefficacy among a sample of Chinese women who underwent infertility treatment.
文摘With a high rate of infertility, it is important to understand the context of fertility and family planning in China, to inform the necessity of supportive care. A literature review was undertaken to explore the societal constructs informing perspectives of childbearing, family planning and infertility, alongside Chinese considerations of fertility treatments, including assisted reproductive technologies and fertility counselling. In China, childbearing attitudes and behaviours are shaped by tensions between traditional cultural values of the filial piety originating from Confucianism, the history of strict family planning policy, the recent termination of one-child policy and the socioeconomic circumstance. For infertile Chinese individuals, the inability to meet these childbearing expectations gives rise to significant pressure and consequent psychological distress, particularly depressive symptoms. Demographic factors such as gender, education, income and geographical location have been found to influence prevalence and degree of depression in infertile Chinese men and women. These difficulties are compounded by barriers of cultural acceptance, legislative restrictions and availability of resources for alternative options such as adoption and surrogacy. It is important that these fertility sociocultural factors are taken into consideration when assisting Chinese patients to access and utilise fertility treatment services.
文摘According to the latest data,globally 15%of couples have infertility and male infertility contributes to 10%of all cases.Infertility can be caused by certain biological changes in the gonads and the reproductive system like azoospermia,oligospermia,asthenospermia,teratozoospermia and hypospermatogenesis.Genetic causes of azoospermia include chromosomal abnormalities,Y chromosome microdeletions and deletion or other mutations of Y-linked genes.The maximum number of the genes are located in the azoospermia factor region of the long arm(Yq)of the Y chromosome.Y chromosome microdeletion is known as the second major genetic cause of spermatogenetic failure.This article aims to review the latest updates on the involvement of Yq microdeletions in male infertility.The diagnostics,prevalence and phenotypic spectrum related to Yq gene microdeletions are discussed.
文摘The goal of this review is to explain the requirement for understanding the genetic structure of infertility arising from male factor and to discuss the essentials of these genetic elements(2). The majority of the population is affected by this disorder caused by male factor infertility(1); but the etiologies are still unknown. After the primary genetic structure in infertile phenotypes is searched, an evaluation can be made. Thus the reasons causing infertility can be discovered and patients can benefit from effective therapies(1). Publications about male infertility within the recent 10 years in the Pubmed database were discussed(1). There are some approachments for describing the function of specificgenes, but no adequate study is present to be useful for diagnosing and treating male infertility(1). Male fertility and fertility in offspring of males are considerably affected by the exact transition of epigenetic information(1). When the genetic factors playing a role in male infertility were analysed, significant steps will be taken for treating patients and determining the reasons of idiopathic infertility(1). Developments in technology associated with the impact of genetics may enable to specify the etiology of male infertility by determining specific infertile phenotype marks(1).
