PREVALENCE AND RISK FACTORS OF INFERTILITY IN TURKEY: EVIDENCE FROM DEMOGRAPHIC AND HEALTH SURVEYS, 1993-2013

The varying estimation of infertility in Ethiopia: the need for a comprehensive definition

BACKGROUND

Infertility is a marginalized sexual and reproductive health issue in low-resource settings. Globally, millions are affected by infertility, but the lack of a universal definition makes it difficult to estimate the prevalence of infertility at the population level. Estimating the prevalence of infertility may inform targeted and accessible intervention, especially for a resource-limited country like Ethiopia. This study aims to estimate the prevalence of female infertility in Ethiopia using the Demographic and Health Survey (DHS) through two approaches: (i) the demographic approach and (ii) the current duration approach.

METHODS

Data from 15,683 women were obtained through the 2016 Ethiopian DHS. The demographic approach estimates infertility among women who had been married/in a union for at least five years, had never used contraceptives, and had a fertility desire. The current duration approach includes women at risk of pregnancy at the time of the survey and determines their current length of time-at-risk of pregnancy at 12, 24, and 36 months. Logistic regression analysis estimated the prevalence of infertility and factors associated using the demographic approach. Parametric survival analysis estimated the prevalence of infertility using the current duration approach. All estimates used sampling weights to account for the DHS sampling design. STATA 14 and R were used to perform the statistical analysis.

RESULTS

Using the demographic definition, the prevalence of infertility was 7.6% (95% CI 6.6-8.8). When stratified as primary and secondary infertility, the prevalence was 1.4% (95% CI 1.0-1.9) and 8.7% (95% CI 7.5-10.1), respectively. Using the current duration approach definition, the prevalence of overall infertility was 24.1% (95% CI 18.8-34.0) at 12-months, 13.4% (95% CI 10.1-18.6) at 24-months, and 8.8% (95% CI 6.5-12.3) at 36-months.

CONCLUSION

The demographic definition of infertility resulted in a lower estimate of infertility. The current duration approach definition could be more appropriate for the early detection and management of infertility in Ethiopia. The findings also highlight the need for a comprehensive definition of and emphasis on infertility. Future population-based surveys should incorporate direct questions related to infertility to facilitate epidemiological surveillance.

Reproductive outcomes among female health care workers

OBJECTIVE

Occupational exposures may be associated with reproductive health and pregnancy outcomes. This study investigated the association between occupational exposures and reproductive health, pregnancy outcomes, and the lactation period among hospital staff.

MATERIALS AND METHODS

Seven hundred thirty-three female healthcare workers from hospitals affiliated with the Tehran University of Medical Sciences were invited to participate in this cross-sectional study. The measurement method for fertility consequences was self-report. Demographic characteristics, occupational data, medical history, and reproductive history were collected via data collection form. Finally, reproductive outcomes were evaluated in different occupational hazard categories.

RESULT

Chemical exposures (solvents) were a risk factor for stillbirth. Prolonged working hours were associated with spontaneous abortion and breastfeeding periods. Shift workers did not have a higher frequency of reproductive and pregnancy outcomes, but the breastfeeding period was significantly decreased in shift workers. Psychiatric disorders were associated with preterm labour, low birth weight, and stillbirth in sequence with nervousness, depression, and mood disturbance. Furthermore, depression affects the breastfeeding period. Moreover, we found a link between job titles and infertility. In addition, socioeconomic status was related to stillbirth and infertility.

CONCLUSION

The study revealed that chemical and ergonomic exposures have associations with some reproductive outcomes. We also conclude that shift work could adversely affect the breastfeeding period. So, implementing some organizational strategies to control adverse health effects of occupational hazards and modifying shift work and working hours for nursing mothers is recommended.

Factors associated with female infertility in Ukraine: results a multicenter study

OBJECTIVE

Aim: To determine the current prevalence of female infertility and characterize and identify risk factors associated with infertility in Ukraine.

PATIENTS AND METHODS

Materials and Methods: Multicenter prospective cohort study was conducted from January 2021 to December 2023 in twelve medical centers from nine regions of Ukraine. Definitions of infertility were adapted from the World Health Organization. According to the data collected from questionnaire, participants were divided into infertile and fertile groups and analyzed associated factors.

RESULTS

Results: Among all the 7,618 participants in this study, the prevalence of female infertility was 24.3%. The prevalence of primary infertility was 5.9%, and the prevalence of secondary infertility was 18.4%. In logistic multivariate regression analyses, female infertility was associated with age of women (p<0.001), age of first sexual intercourse (p<0.001), history of gynecological surgery (p<0.001), marital status (p<0.001), age of marriage (p<0.001), decreased ovarian reserve (DOR) (p=0.006), family history of infertility (p<0.001), history of cervicitis (p=0.007), history of surgical abortion (p<0.001), history of endometritis (p=0.027), bacterial vaginosis (p=0.023), and aerobic vaginitis (< 0.001).

CONCLUSION

Conclusions: Our data suggest a high prevalence of female infertility in Ukraine. The prevalence of secondary infertility was higher than primary infertility. Age of women, age of first sexual intercourse, history of gynecological surgery, marital status, age of marriage, DOR, family history of infertility, history of cervicitis, history of surgical abortion, history of endometritis, bacterial vaginosis, and aerobic vaginitis were associated with infertility.

Fertility, early menopause and pregnancy outcomes of patients with Takayasu's arteritis

OBJECTIVES

The reproductive health of patients with Takayasu's arteritis (TA) is an important issue. Systemic inflammation and treatments used in TA may affect female reproductive organs, leading to infertility, maternal and fetal morbidity, and early menopause. This study aimed to evaluate fertility, early menopause and pregnancy outcomes of patients before and after TA diagnosis. In addition, pregnancy morbidities following TA diagnosis were analysed for each cluster.

STUDY DESIGN

Two hundred and two patients with TA (184 females) who met the 1990 American College of Rheumatology criteria were registered in the prospective database of Hacettepe University Vasculitis Research Centre by the end of February 2020. Demographic and clinical features, comorbidities, distribution of vascular involvement, obstetric histories and outcomes were evaluated retrospectively. Patients with TA were classified according to novel proposed disease clusters. Early menopause was defined as menopause before 45 years of age.

RESULTS

One hundred and twenty-one female patients with TA, for whom gynaecological records and marriage status could be obtained, were included in the study. Ninety-seven patients were married, of whom 12 (12.5 %) patients were infertile. In total, there were 238 pregnancies in 83 female patients with TA: 203 before TA diagnosis, 35 after TA diagnosis, and two patients were diagnosed during pregnancy. Compared with the pre-diagnosis group, maternal complications were significantly more common in the post-diagnosis group [23 (11.3 %) vs 9 (25.7 %); p = 0.048]. The most common maternal complication was gestational hypertension (12.1 %). Fetal complications were common in both groups (21.5 % pre-diagnosis vs 34.2 % post-diagnosis; p = 0.18), and included prematurity, intrauterine growth retardation and low birth weight. According to novel disease subsets, post-diagnosis patients were classified as C1 (n = 3, 15.7 %), C2 (n = 9, 47.3 %) or C3 (n = 6, 31.5 %). One patient could not be classified. There was no difference in obstetric outcomes between these subgroups. Early menopause was observed in 20 (16.5 %) of 121 patients, but some patients had not yet reached 45 years of age.

CONCLUSION

Infertility was higher in patients with TA in comparison with the general population in Turkey (12.5% vs 8.6%), and the early menopause rate was lower in patients with TA (16.7% vs 36.1%). Pregnancies following a diagnosis of TA had more maternal complications than pre-diagnosis pregnancies. Fetal complications were more common both pre- and post-diagnosis. Chronic inflammation before TA diagnosis may lead to increased infertility and fetal complications.

Evaluation of health-related quality of life in childhood cancer survivors

BACKGROUND

Considering the high survival rates of childhood cancers and their stable incidence, concepts such as quality of life (QOL) and health-related quality of life (HRQOL) are impactful issues that have consistently retained their importance worldwide.

OBJECTIVE

This study aimed to evaluate HRQOL at least 5 years after treatment in childhood cancer survivors (CCSs) with the hypothesis that their QOL could be adversely affected later in their lives. Additionally, we sought to assess the parents of pediatric CCSs with respect to HRQOL.

PATIENTS AND METHODS

We evaluated CCSs aged 8-18 years and compared the results with healthy controls (matched for age and sex). The parents of the pediatric CCSs and control groups were also analyzed. A total of 174 cases (patients and controls) and 168 parents (of patients and controls) were included in the study. HRQOL was evaluated by applying the Pediatric Quality of Life Inventory (PedsQL).

RESULTS

The mean HRQOL scores of CCSs were significantly lower than those of the controls (p= 0.04). No differences were found between the parents of these groups. The physical and social functionality scores of CCSs were significantly lower when compared to healthy controls (p = 0.02 and p<0.01, respectively). In addition, according to cancer type, the HRQOL scores of those with solid tumors were found to be significantly lower than those with hematological cancers (p=0.02).(p = 0.02) CONCLUSION: This study shows that HRQOL is lower in CCSs compared to healthy controls. The most important differences in HRQOL among CCSs were found in the physical and social subdimensions compared to the controls. In this regard, it appears to be vital to provide mental support to CCSs after cancer treatment. These findings also indicate the need for health-focused social policies that can increase HRQOL in CCSs.

Association of the Cumulative Live Birth Rate with the Factors in Assisted Reproductive Technology: A Retrospective Study of 16,583 Women

The cumulative live birth rate (CLBR) can better reflect the overall treatment effect by successive treatments, and continuous rather than categorical variables as exposure variables can increase the statistical power in detecting the potential correlation. Therefore, the dose-response relationships might find an optimal dose for the better CLBR, offering evidence-based references for clinicians. To determine the dose-response relationships of the factors and the optimal ranges of the factors in assisted reproductive technology (ART) associated with a higher CLBR, this study retrospectively analyzed 16,583 patients undergoing the first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) from January 2017 to January 2019. Our study demonstrated the optimal ranges of age with a higher CLBR were under 32.10 years. We estimated the CLBR tends to increase with increased levels of AMH at AMH levels below 1.482 ng/mL, and the CLBR reaches a slightly high level at AMH levels in the range from 2.58-4.18 ng/mL. The optimal ranges of basal FSH with a higher CLBR were less than 9.13 IU. When the number of cryopreserved embryos was above 1.055 and the number of total transferred embryos was 2, the CLBR was significantly higher. In conclusion, there is a non-linear dose-response relationship between the CLBR with age, AMH, basal FSH, and the number of cryopreserved embryos and total transferred embryos. We proposed the optimal ranges of the five factors that were correlated with a higher CLBR in the first oocyte retrieval cycle, which may help consultation at IVF clinics.

Is the Occurrence of Gestational Diabetes Mellitus in Pregnancies Higher Following In Vitro Fertilization Treatment? Why? A Retrospective Cohort Study

Purpose: This study aim to determine the occurrence of gestational diabetes mellitus (GDM) in pregnancies after IVF treatment and to evaluate the factors that reduce this risk. Methods: This retrospective cohort study was conducted using the medical records of pregnant women who conceived following IVF at the in-vitro fertilization center between 2002–2019. The data were obtained from medical records and phone interviews. Univariate and multivariate logistic regression analyses were performed. Results: The incidence of GDM was found to be 16.7%. The regression model indicated that the risk of GDM was 4.57 times higher in the age group 36–40 at conception during the IVF cycle than the age group 31–35 (95% CI = 1.18–17.73, p = .028). Furthermore, women who conceived after the second IVF trial had a risk of GDM 3.464 times higher than those that conceived after their first IVF trial (95% CI = 1.07–11.23, p= .038). Conclusion: As age and number of IVF trials increase in infertile women, the risk of GDM increases after IVF treatment.

University students' attitudes toward gender roles and infertility: A descriptive and correlational study

PURPOSE

To examine the relationship between university students' attitudes toward gender roles and infertility.

DESIGN AND METHODS

This descriptive and correlational study was conducted with 743 university students between September and December 2020. Data were collected using a personal information form, the Gender Roles Attitude Scale, and the Attitudes Towards Infertility Scale through online forms.

FINDINGS

It was found that attitudes toward gender roles and infertility could be influenced by some sociodemographic factors, for instance, students' sex, education, and family type. There was also a moderate and positive correlation between attitudes toward gender roles and infertility.

PRACTICE IMPLICATIONS

The present study contributes to a better understanding of the social construction and attitudes toward gender roles and infertility. For a better future, it is recommended that nurses help and support university students in raising awareness about such an important social problem.

Human papillomavirus prevalence in unexplained infertile women with chronic endometritis

Introduction: This study investigates unexplained infertile women with or without chronic endometritis (CE) and examines the prevalence of the human papillomavirus (HPV) in this population. Material and Method: This study was done with a cross-sectional and retrospective method. The prevalence of HPV infection and related cases in the participants were examined. In this study, 15 infertile women with CE and 64 infertile women without CE were and analyzed from four perspectives: negative HPV, low-risk HPV, probable high-risk HPV, and the presence of high-risk HPV. Results: The participants have mean age of 32.89 years ±3.95. High-risk HPV infection was detected in 3 (20%) and 11 (17%) of the patients with and without CE, respectively (p>0.05). The negative HPV (2 (13%) and 17 (26%)), low-risk HPV (3 (20%) and 20 (31%)), and probable high-risk HPV (7 (46%) and 16 (25%)) in infertile women with CE and infertile women had no significantly different prevalence (p>0.05). The two studied groups had no significantly different mean age, body mass index (BMI), and Infertility duration were not in (P=0.08, P=0.932, and P=0.283, respectively). Conclusion: HPV has no significantly different prevalence in unexplained infertile women with and without CE. It is recommended that this study be repeated with more unexplained infertile women with CE.

Incidence and risk factors of infertility among couples who desire a first and second child in Shanghai, China: a facility-based prospective cohort study

Background

With the implementation of the two-child policy in China, more couples have expressed the desire to have another child. We conducted this study to evaluate the incidence of infertility and risk factors in couples intending to have a first and second child.

Methods

From 2013 to 2017, a prospective cohort study was conducted at the pre-pregnancy center of the International Peace Maternal and Child Health Hospital. The participants were selected by screening and random sampling couples who came to the pre-pregnancy center. Data regarding patient sociodemographic characteristics, reproductive and gynecological history, male disease history, and laboratory and imaging examination results were collected. Couples were followed up every 3 months until pregnancy or for 12 months, whichever came first. Multi-factor logistic regression was used to analyze risk factors for infertility. Adjusted odds ratios (aORs) and corresponding 95% confidence intervals (CIs) were calculated and adjusted for potential confounding factors.

Results

The overall infertility incidence was 16.95% (369/2177). The infertility incidence of “first child intention” and “second child intention” was 19.30% (355/1839) and 4.14% (14/338), respectively. This study found great differences in both infertility rate (P < 0.001) and risk factors between the two groups. Risk factors for “first child intention” infertility included advanced age (> 35 years) (aOR = 1.70, 95% CI 1.27–2.28), abnormal body mass index (BMI) (aOR = 1.58, 95% CI 1.31–6.26), longer menstrual periods (aOR = 4.47, 95% CI 2.25–8.88), endometrial polyps (aOR = 2.52, 95% CI 1.28–4.97), polycystic ovarian syndrome (PCOS) (aOR = 6.72, 95% CI 1.79–7.39), salpingostomy (aOR = 3.44, 95% CI 1.68–7.07), and history of mycoplasma (aOR = 1.54, 95% CI 1.09–2.40). However, in the “second child intention” group, clinical risk factors slightly differed and included leiomyoma (aOR = 5.60, 95% CI 1.06–29.76), and higher age (> 40 years) (aOR = 7.36, 95% CI 1.01–53.84).

Conclusion

The overall infertility rate in Shanghai is similar to that of other large cities in China. Marriage at advanced ages has become increasingly common. As such, the government must consider subsidies to encourage childbirth at childbearing ages, which can improve fertility levels.

Infertility is defined as pregnancy failure after at least 12 months of regular unprotected sexual intercourse. Few researchers have investigated the infertility rate in Shanghai in the past 15 years, and little attention has been paid to the infertility of couples hoping to have a second child. We conducted a prospective cohort study in Shanghai to evaluate infertility incidence and risk factors in couples intending to have a first or second child. The investigators administered a questionnaire survey to the participants and followed them for 1 year. Finally, 1839 couples intending to have a first child and 338 couples intending to have a second child were included in this study. The overall infertility incidence was 16.95% (369/2177). However, the infertility incidence of the “first child intention” and “second child intention” groups was 19.30% (355/1839) and 4.14% (14/338), respectively. Risk factors for “first child intention” infertility included advanced age (> 35 years), abnormal body mass index (BMI), longer menstrual periods, endometrial polyps, polycystic ovarian syndrome (PCOS), salpingostomy, and history of mycoplasma; in the “second child intention” group, clinical risk factors slightly differed and included leiomyoma and advanced age (> 40 years). Since studies have shown large differences in infertility risk factors between the two groups, early and targeted intervention for couples in different high-risk groups can help reduce infertility.

Current situation of menstruation and gynecological diseases prevalence among Chinese women: a cross-sectional study

Background

Gynecological diseases have been taken attention and studied worldwide. Although, no recent studies have delineated the magnitude of gynecological diseases among Chinese women. This study aims to evaluate the current situation of menstruation and gynecological diseases prevalence among Chinese women.

Methods

A cross-sectional study was conducted at a hospital affiliated with Nanjing medical university in Nanjing, China between September 2021 and February 2022. A sample size of 977 women aged 18–52 years participated in a face-to-face interview questionnaire. Logistic regression was performed to determine whether pubertal timing and menstrual characteristics were associated with gynecological diseases.

Results

The most prevalent gynecological disease was dysmenorrhea (45.96%), followed by polycystic ovary syndrome, PCOS (19.04%), uterine fibroids (14.23%), spontaneous abortion (13.20%), trouble conceiving (12.59%), ovarian dysfunction (11.16%) and endometriosis (4.09%). In the adjusted model, heavy bleeding with large clots was associated with an increased risk of dysmenorrhea (odds ratio, OR = 5.01, 95% Confidence interval, CI 2.26, 11.10; p = 0.000), while history of precocious puberty diagnosis was associated with a reduced risk of dysmenorrhea (OR = 0.50, 95%CI: 0.26, 0.94; p = 0.031). Regular menstrual cycle in the past 12 months and regular menstrual periods were associated with decreased risk of PCOS (OR = 0.44, 95%CI 0.30, 0.65; p = 0.000) and (OR = 0.52, 95%CI 0.36, 0.74; p = 0.000), respectively. Histories of early thelarche, early menarche, and precocious puberty diagnosis were associated with increased risk of ovarian dysfunction (OR = 1.96, 95%CI 1.25, 3.08, p = 0.004), (OR = 2.26, 95%CI 1.24, 4.13; p = 0.008) and (OR = 2.79, 95%CI 1.36, 5.74; p = 0.005), respectively. Heavy bleeding and heavy bleeding with large clots were associated with endometriosis (OR = 4.92, 95%CI 1.50, 16.15, p = 0.009) and (OR = 5.67, 95%CI 1.42, 22.56; p = 0.014), respectively.

Conclusions

The prevalence of gynecological diseases is increasing among Chinese women and pubertal timing and menstrual characteristics may be associated with some gynecological diseases, specifically dysmenorrhea, PCOS, ovarian dysfunction, and endometriosis.

Multi-dimensional-double-spiral (MDDS) inertial microfluidic platform for sperm isolation directly from the raw semen sample

Here, we propose a fully-automated platform using a spiral inertial microfluidic device for standardized semen preparation that can process patient-derived semen samples with diverse fluidic conditions without any pre-washing steps. We utilized the multi-dimensional double spiral (MDDS) device to effectively isolate sperm cells from other non-sperm seminal cells (e.g., leukocytes) in the semen sample. The recirculation platform was employed to minimize sample dependency and achieve highly purified and concentrated (up to tenfold) sperm cells in a rapid and fully-automated manner (~ 10 min processing time for 50 mL of diluted semen sample). The clinical (raw) semen samples obtained from healthy donors were directly used without any pre-washing step to evaluate the developed separation platform, which showed excellent performance with ~ 80% of sperm cell recovery, and > 99.95% and > 98% removal of 10-μm beads (a surrogate for leukocytes) from low-viscosity and high-viscosity semen samples, respectively. We expect that the novel platform will be an efficient and automated tool to achieve purified sperm cells directly from raw semen samples for assisted reproductive technologies (ARTs) as an alternative to density centrifugation or swim-up methods, which often suffer from the low recovery of sperm cells and labor-intensive steps.

Prevalence and associated factors of infertility among 20-49 year old women in Henan Province, China

Background

Infertility is a reproductive health problem which affects not only individuals, families and social populations. Recently, the infertility rate in China has a trend of increase year by year, and few studies have reported the infertility rate in Henan Province, China. The aim of this study was to investigate the current prevalence and associated factors of infertility among women of childbearing age in Henan Province, China.

Methods

This cross-sectional study was conducted from March 2019 to October 2019. We sampled 765 women who were 20–49 years old in eight hospitals of four cities in Henan Province, China. This survey included a questionnaire, physical examination, vaginal ultrasound examinations, and serum anti-Mullerian hormone (AMH) assessment, all of which were conducted under uniform standards by trained personnel. According to the data collected from questionnaire, participants were divided into infertile and fertile groups and analyzed associated factors.

Results

Among all the 765 participants in this study, the prevalence of infertility was 24.58%. The prevalence of primary infertility was 6.54%, and the prevalence of secondary infertility was 18.04%. In logistic multivariate regression analyses, infertility was associated with age (p < 0.001), history of gynecological surgery (p < 0.001), sweet food (p = 0.003) and decreased ovarian reserve (DOR) (p < 0.001). After further analyses, factors associated with primary infertility were age of marriage (p = 0.006), age of first sexual intercourse (p = 0.003), long-term air-conditioning environment (p < 0.001), decreased ovarian reserve (p = 0.005) and age (p = 0.002). And factors associated with secondary infertility were history of gynecological surgery (p < 0.001), decreased ovarian reserve (p = 0.002), waist-to-hip ratio (WHR) above 0.85 (p = 0.043), delivery times (p = 0.001) and ages (p < 0.001).

Conclusion

The prevalence of infertility among women aged 20–49 was 24.58% and only 61.17% infertile women sought medical help in Henan Province, China. Age, history of gynecological surgeries and DOR may increase the risk of infertility. Local public health departments and medical professionals need to discharge their duty of reducing the high incidence of infertility and protecting women’s reproductive health.

Supplementary Information

Infertility prevalence rate has increased in the past 30 years. Infertility plagues thousands of women of childbearing age. Although not life-threatening, the detrimental influence of infertility to patients, their families, and society should not be underestimated, especially in China. In order to investigate the prevalence of infertility, determine the associated factors, and promote disease prevention and treatment, we conducted a cross-sectional study among 20–49 year old women in Henan, one of the central provinces of China.

This study distributed 920 questionnaires and collected 803 completed questionnaires. Interviews, questionnaires, and physical and ultrasound examinations were done.

Among all the 765 participants in this study, the prevalence of infertility was 24.58%. The prevalence of primary infertility was 6.54%, and the secondary infertility was 18.04%. Age, history of gynecological surgeries and DOR may increase the risk of infertility.

In conclusion, among women aged 20–49 years in Henan Province, China, the prevalence of infertility in 2019 was 24.58% and 61.17% of infertile women sought medical help.

Effectiveness of Exercise Training on Male Factor Infertility: A Systematic Review and Network Meta-analysis

CONTEXT

Mounting evidence from the literature suggests that different types of training interventions can be successful at improving several aspects of male reproductive function in both fertile and infertile populations.

OBJECTIVE

The aim of this study was to evaluate the effectiveness of exercise training on male factor infertility and seminal markers of inflammation.

DATA SOURCES

We searched PubMed, CISCOM, Springer, Elsevier Science, Cochrane Central Register of Controlled Trials, Scopus, PEDro, Ovid (Medline, EMBASE, PsycINFO), Sport Discus, Orbis, CINAHL, Web of Science, ProQuest, and the ClinicalTrials.gov registry for randomized controlled trials (RCTs) that analyzed the impacts of selected types of exercise interventions on markers of male reproductive function and reproductive performance.

STUDY SELECTION

A total of 336 records were identified, of which we included 7 trials reporting on 2641 fertile and infertile men in the systematic review and network meta-analysis.

LEVEL OF EVIDENCE

Level 1 (because this is a systematic review of RCTs).

DATA EXTRACTION

The data included the study design, participant characteristics, inclusion and exclusion, intervention characteristics, outcome measures, and the main results of the study.

RESULTS

The results of network meta-analysis showed that, compared with a nonintervention control group, the top-ranking interventions for pregnancy rate were for combined aerobic and resistance training (CET) (relative risk [RR] = 27.81), moderate-intensity continuous training (MICT) (RR = 26.67), resistance training (RT) (RR = 12.54), high-intensity continuous training (HICT) (RR = 5.55), and high-intensity interval training (HIIT) (RR = 4.63). While the top-ranking interventions for live birth rate were for MICT (RR = 10.05), RT (RR = 4.92), HIIT (RR = 4.38), CET (RR = 2.20), and HICT (RR = 1.55). Also, with the following order of effectiveness, 5 training strategies were significantly better at improving semen quality parameters (CET > MICT > HICT > RT > HIIT), seminal markers of oxidative stress (CET > MICT > HIIT > HICT > RT), seminal markers of inflammation (CET > MICT > HIIT > RT > HICT), as well as measures of body composition and VO₂max (CET > HICT > MICT > HIIT > RT).

CONCLUSION

The review recommends that the intervention with the highest probability of being the best approach out of all available options for improving the male factor infertility was for CET.

Male Sexual Dysfunctions in the Infertile Couple-Recommendations From the European Society of Sexual Medicine (ESSM)

Introduction

Sexual dysfunctions (SDs) have been frequently reported among male partners of infertile couples due to psychogenic, relational and/or organic issues related with the inability to conceive. Likewise, male infertility (MI) could be a consequence of sexual dysfunctions.

Aim

To review the evidence on the prevalence and treatment of male SDs in men of infertile couples and provide clinical recommendations on behalf of the European Society of Sexual Medicine (ESSM).

Methods

The MEDLINE database was searched in September 2019 for randomized clinical trials (RCTs), meta-analyses and open-label prospective or retrospective studies investigating the presence of erectile dysfunction (ED) and/or ejaculatory dysfunctions (EjDs) and/or low sexual desire (LSD) in conjunction with infertility.

Main Outcome Measure

The panel provided statements on: (i) Prevalence and association between SDs and MI; (ii) Treatment of male SDs in men of infertile couples.

Results

ED has been reported in 9% to 62% of male partners of infertile couples, with severe impairment observed in only 1% to 3% of ED cases. Moreover, worse semen parameters have been associated with greater ED severity. Phosphodiesterase type 5 inhibitors (PDE5is) can be safely used to treat ED among patients seeking fatherhood. Male partners of infertile couples are at higher risk of premature ejaculation (PE). Retrograde ejaculation (RE) and anejaculation are a cause of MI and can be managed with electroejaculation (EEJ) or penile vibratory stimulation (PVS) or, alternatively, with oral treatments, however the latter with limited documented success. Low sexual desire has been reported by one third of men of infertile couples.

Conclusion

ED could significantly affect male partners of infertile couple; PDE5is should be suggested to ensure an effective and satisfactory sexual relationship of the couple. Anejaculation and RE should be considered as a possible cause of MI and treated accordingly. Low sexual desire is frequently reported among men of infertile couple and could be a symptom of other systemic conditions or psychological distress. Capogrosso P, Jensen CFS, Rastrelli G, et al.

Carbamazepine-induced sperm disorders can be associated with the altered expressions of testicular KCNJ11/miR-let-7a and spermatozoal CFTR/miR-27a

Male infertility is a global health problem, and the underlying molecular mechanisms are not clearly known. Ion channels and microRNAs (miRNAs), known to function in many vital functions in cells, have been shown to play a significant role in male infertility through changes in their expressions. The study aimed to evaluate the alterations of testicular and/or spermatozoal potassium voltage-gated channel subfamily J member 11 (KCNJ11), Cystic fibrosis transmembrane conductance regulator (CFTR), miR-let-7a and miR-27a expressions in carbamazepine-related male infertility. Here, we showed that carbamazepine reduced sperm motility, increased abnormal sperm morphology, and impaired hormonal balance as well as increased relative testis weight and decreased relative seminal vesicle weight. On the other hand, downregulated KCNJ11 and upregulated miR-let-7a expressions were determined in testis (p < .05). Also, downregulated KCNJ11 and upregulated CFTR and miR-27a expressions were found in spermatozoa (p < .05). Interestingly, altered testicular KCNJ11 and miR-let-7a expressions were correlated with decreased sperm motility and elevated sperm tail defect. Besides, spermatozoal CFTR and miR-27a expressions positively correlated with sperm tail defects. The results indicated a significant relationship between ion channel and/or miRNA expression alterations and impaired sperm parameters due to carbamazepine usage.

Infertility policy analysis: a comparative study of selected lower middle- middle- and high-income countries

BACKGROUND

Infertility has recently become a salient but neglected global issue. Policies to address the sexual and reproductive health and rights (SRHR) are vital, especially in lower middle and middle-income countries (LMICs). Hence, the aim of this study was to compare the national infertility policies in the selected countries (LMICs comparing with high-income) to determine gaps or to confirm desirable policies in the given health systems.

METHODS

This study has executed a comparative policy analysis of infertility services using the universal health coverage framework (financial protection, population coverage, and service features) in three scopes (prevention, treatment, and supportive care). Seven countries that had infertility programs in their health sectors were selected.

RESULTS

The results showed that financial protection was good in high and middle-income countries, but in a lower middle income, and in one high-income country was poor. The findings also showed that health systems in the same countries had no infertility services for men. Preventive and supportive care services were neglected in LMICs by governments.

CONCLUSION

The findings indicate that income is not the only factor that fulfills universal health coverage for infertility care services. Perhaps to achieve equity in infertility care services, it should be seen as a universal human right to accomplish the right to have a child and to have a life with physical and mental health for all men and women.

Probiotic effects on sperm parameters, oxidative stress index, inflammatory factors and sex hormones in infertile men

Decreased sperm motility is one of the main causes of male infertility. The aim of this study was to evaluate the effects of probiotic supplementation on semen quality, seminal oxidative stress biomarkers, inflammatory factors and reproductive hormones. In this randomised, double-blind controlled clinical trial, 52 men with idiopathic oligoasthenoteratozoospermia attending a urology clinic, were randomly assigned to either an intervention or placebo (n = 26) group. This investigation was registered by the identification code of IRCT20141025019669N7 in the clinical trials registry of Iran. The Intervention group took 500 mg of Probiotics daily and the placebo group took a daily placebo for 10 weeks. Semen parameters, total antioxidant capacity, malondialdehyde, inflammatory factors and reproductive hormones were measured at baseline and at the end of the study. After the intervention, ejaculate volume, number, concentration and the percentage of motile sperm, total antioxidant capacity of plasma significantly increased and the concentration of plasma malondialdehyde and inflammatory markers significantly decreased in the intervention group. Probiotic supplementation in infertile men lead to a significant increase in sperm concentration and motility and a significant reduction in oxidative stress and inflammatory markers. Therefore, oral intake of probiotics has the potential to be one of the ways to deal with oxidative damage of sperm.

Global, regional, and national prevalence and disability-adjusted life-years for infertility in 195 countries and territories, 1990-2017: results from a global burden of disease study, 2017

To provide comprehensive estimates of the global, regional, and national burden of infertility from 1990 to 2017, using findings from a 2017 study on the global burden of disease (GBD), we assessed the burden of infertility in 195 countries and territories from 1990 to 2017. DisMod-MR 2.1 is a Bayesian meta-regression method that estimates non-fatal outcomes using sparse and heterogeneous epidemiological data. Globally, the age-standardized prevalence rate of infertility increased by 0.370% per year for females and 0.291% per year for males from 1990 to 2017. Additionally, age-standardized disability-adjusted life-years (DALYs) of infertility increased by 0.396% per year for females and 0.293% per year for males during the observational period. An increasing trend to these burden estimates was observed throughout the all socio-demographic index (SDI) countries. Interestingly, we found that high SDI countries had the lowest level of prevalence and DALYs in both genders. However, the largest increasing trend was observed in high-SDI countries for females. By contrast, low-SDI countries had the largest increasing trend in males. Negative associations were observed between these burden estimates and the SDI level. The global disease burden of infertility has been increasing throughout the period from 1990 to 2017.

Evaluation of Male Infertility Prevalence with Clinical Outcomes in Middle Anatolian Region

OBJECTIVE

the aim of this study is to determine the prevalence of male factor infertility with the clinical patterns of patients in our region.

MATERIALS AND METHODS

this is a descriptive retrospective study of 406 infertility cases presented at our urology clinic from February 2018 to February 2019. We assessed hormone and physical examination data, semen analysis results, the contribution of male and female factors to infertility, and types of infertility (i.e., primary or secondary).

RESULTS

the age of the male patients ranged from 18 to 50 years, with a mean of 30 ± 5 years. Asthenozoospermia was the leading cause of male factor infertility in 77 patients (19%). Male factors as the sole cause of infertility were found in 185 (45.6%) couples. Female factors as the sole cause were found in 32 couples (7.9%). Primary infertility was determined in 314 (77.3%) patients, and 92 (22.7%) had secondary infertility.

CONCLUSION

according to our results, the male infertility rate was high among couples reporting infertility. Couples should be informed about the causes of infertility, which may be due factors attributed to either sex.

Increasing misreporting levels of induced abortion in Turkey: is this due to social desirability bias?

Women tend to under-report or misreport their abortion experiences, mainly because abortion is considered a sensitive issue for cultural, religious, political or other reasons in many countries across the world. Turkey, where induced abortion is an increasingly sensitive issue due to intense statements against induced abortion on religious grounds by influential politicians, and a hidden agenda to prohibit the practice, especially in public health facilities, in recent years, is no exception. This study focused on the increase in level of misreporting of induced abortion in Turkey and its link to social desirability bias using pooled data from 1993 and 2013 Turkish Demographic and Health Surveys. A probabilistic classification model was used to classify women's reported abortions. The findings confirmed that the level of misreporting of induced abortions has increased from 18% to 53% among all terminated pregnancies over the period 1993-2013 in Turkey. This marked increase, especially among women in the lower socioeconomic sections of society, may be largely associated with the prevailing political environment, and increase in social stigmatization against induced abortion in Turkey over recent decades.

Impact of subclinical hypothyroidism and thyroid autoimmunity on clinical pregnancy rate after intrauterine insemination in euthyroid women

Objective:

This study aimed to evaluate the association between subclinical hypothyroidism and thyroid autoantibodies with clinical pregnancy rate after intrauterine insemination (IUI) in euthyroid women.

Methods:

In this prospective cohort study, we recruited 497 women who underwent IUI treatment. We assessed thyroid function tests, thyroid antibodies and clinical pregnancy rates of the patients.

Results:

The patients were divided into two groups according to TSH values: normal group, n=387, and subclinical hypothyroidism group 2, n=110. The clinical pregnancy rate was 15.2% in the Control Group and 17.3% in the study group (p=0.656). In the Study Group, 35% of the patients had anti-TPO positivity (p=0.531) and 42.1% of the patients had anti-TG positivity (p=0.285). There was no statistically significant difference in clinical pregnancy rates between the groups in terms of antithyroid antibody positivity (p=0.54; p=0.559, respectively).

Conclusion:

Anti-TPO antibodies and subclinical hypothyroidism had no impact on clinical pregnancy rates in the women submitted to IUI.

Infertility in the Moroccan population: major risk factors encountered in the reproductive health centre in Rabat

Infertility is responsible for a major cost burden for patients and health care systems. Therefore identifying preventable risk factors for infertility may contribute to the development of more cost-effective approaches to solving the infertility problem. However, such investigations have never been conducted in Morocco. Thereby, the objective of the present study was to determine the occurrence and distribution of these factors among Moroccan infertile couples. This retrospective study included 1265 infertile couples who attended the Assisted Reproductive Technology Unit of the Reproductive Health Centre of the University Hospital Ibn Sina in Rabat. All couples had been infertile for at least 1 year and both partners were fully investigated. Couples had primary and secondary infertility in 77.2% and 22.8% of cases, respectively. Women were overweight in 47.9% of cases and obese in 25.8% of cases while men were overweight in 44.6% of cases and obese in 14.7% of cases. 18.9% of women and 17.5% of men had a previous abdominopelvic or urogenital surgery. A history of sexually transmitted infection was reported by 7% of men and 5.8% of women. A history of tuberculosis was found 9.3% of women and 4.8% of men. In addition, 31.7% of men were cigarette smokers and 8.4% consumed alcohol. The study showed that preventable risk factors of infertility are common among Moroccan infertile couples. However, additional studies are required to investigate each factor and its relation to infertility in the Moroccan population.
