Risks Factors and Treatment Use Related to Infertility and Impaired Fecundity Among Reproductive-Aged Women

A GREB1-steroid receptor feedforward mechanism governs differential GREB1 action in endometrial function and endometriosis

Cellular responses to the steroid hormones, estrogen (E2), and progesterone (P4) are governed by their cognate receptor's transcriptional output. However, the feed-forward mechanisms that shape cell-type-specific transcriptional fulcrums for steroid receptors are unidentified. Herein, we found that a common feed-forward mechanism between GREB1 and steroid receptors regulates the differential effect of GREB1 on steroid hormones in a physiological or pathological context. In physiological (receptive) endometrium, GREB1 controls P4-responses in uterine stroma, affecting endometrial receptivity and decidualization, while not affecting E2-mediated epithelial proliferation. Of mechanism, progesterone-induced GREB1 physically interacts with the progesterone receptor, acting as a cofactor in a positive feedback mechanism to regulate P4-responsive genes. Conversely, in endometrial pathology (endometriosis), E2-induced GREB1 modulates E2-dependent gene expression to promote the growth of endometriotic lesions in mice. This differential action of GREB1 exerted by a common feed-forward mechanism with steroid receptors advances our understanding of mechanisms that underlie cell- and tissue-specific steroid hormone actions.

The prevalence of infertility and factors associated with infertility in Ethiopia: Analysis of Ethiopian Demographic and Health Survey (EDHS)

BACKGROUND

Despite having a high fertility rate, low-resource countries are also home to couples with infertility problems. Although many couples are suffering from the psychological impacts of infertility, its level and determinants are not adequately known. The main objective of this study is to assess the prevalence and factors associated with infertility among couples in Ethiopia using the 2016 Ethiopian Demographic and Health Survey (EDHS) data.

METHOD

The study employed a cross-sectional study design extracting variables from the 2016 EDHS. The study included all married or cohabitating women aged 15 to 49 years in the Couples Recode (CR) file data set. Weighted samples of 6141 respondents were analyzed. We used Stata 14 software for analyzing the data. The association of selected independent variables with primary, secondary, and total infertility was analyzed using a logistic regression model. We presented the results using an adjusted odds ratio (AOR) with a 95% confidence interval (CI) and a p-value <0.05 as a cut-off point for declaring statistical significance.

RESULTS

The prevalence of infertility in the past 12 months was 24.2% (95% CI: 23.1-25.3%), of which the majority (90.7%) was secondary infertility. Greater than 35 years of age (AOR = 2.45, 95% CI (1.58-3.79)), rural residence (AOR = 1.06, 95% CI (1.01-1.39)), smoking (AOR = 2.29, 95% CI (1.39-3.77)), and <18.5 Body Mass Index (BMI) (AOR = 1.71, 95% CI (1.43-2.04)) were significantly associated with infertility. Conversely, infertility was less likely among women with formal education and better wealth index. Primary infertility was significantly higher among women whose partners drink alcohol (AOR = 1.55; 95% CI 1.06-2.28)) and chew khat (AOR = 1.62; 95% CI (1.12-2.36)). Secondary infertility was significantly higher among women with <18.5 BMI (AOR = 1.59, 95% CI (1.37-1.84)), >30 BMI (AOR = 1.54; 95% CI 1.01-2.35)), and <15 years of age at first birth (AOR = 1.40; 95% CI 1.15-1.69)).

CONCLUSION

More than one in five couples in Ethiopia has an infertility problem. Both male and female-related factors are associated with infertility. Primary infertility was significantly higher among women whose partner chews khat and drinks alcohol. Secondary infertility was significantly associated with being underweight, obese, smoking, and young age at first birth. Hence, taking action on preventable factors is the most critical treatment approach and will improve the health status of the couples in other ways.

Factors associated with medical help-seeking for infertility in developed countries: A narrative review of recent literature

The reasons why people decide for or against seeking medical help for infertility are still far from clear. With advances in reproductive medicine, use of medically-assisted reproduction has increased over the last three decades. Over the same period, an appreciable amount of quantitative studies on the determinants of medical help-seeking for infertility has accumulated. However, to our knowledge this narrative review is the first to summarize and evaluate findings from these studies. This review includes 39 studies carried out in 11 countries, covering the period 1990-2019. We have identified five categories of determinants of help-seeking: socio-demographic variables, socio-economic factors, reproductive history, attitudes, and psychological factors. Each category consists of several variables. Considerable knowledge has accumulated on socio-economic variables, indicating that there is social inequality in access to treatments in several countries. Less is known about marital status, attitudes and psychological factors. Findings on the latter two mostly derive from two US surveys. Overall, the body of research appears heterogeneous and fragmented. Studies differ in central aspects of study design (definitions of the analysis sample and of help-seeking, type of analysis (bivariate or multivariate), set of variables included in multivariate studies) making comparisons of findings difficult. Low comparability is reinforced by country differences in the provision of treatment, legislation on access and treatment coverage. The majority of papers lack a theoretical foundation or reference to any theory. Using a theoretical framework to guide empirical research could help to overcome the problems described above. Single-country studies should include information on legal and cultural context. More studies from countries other than the US are needed as well as multi-country studies in order to develop a systematic understanding of how macro-level structures relate to decisions about medical help-seeking. This review should assist future researchers in their attempt to conduct studies on help-seeking for infertility.

On estimating the prevalence of use of medically assisted reproduction in developed countries: a critical review of recent literature

BACKGROUND

Existing reviews on the prevalence of use of medically assisted reproduction (MAR) are relatively old and include mainly studies from the 1980s and 1990s. Since then, MAR has developed at a rapid pace, public awareness and acceptance of medical solutions to infertility problems has increased, and, consequently, the use of MAR has risen in developed countries.

OBJECTIVE AND RATIONALE

This study provides a comprehensive overview of the state of research on the prevalence of MAR use in women and men, as well as a critique of methodology used in studies of the use of MAR, and suggestions for moving forward.

SEARCH METHODS

Articles were located via the databases Academic Search Complete, Biomed Central, FirstSearch, Google Scholar, Medline, Health and Medical Collection, Medline and Social Science Citation Index using the key words 'infertile', 'infertility', 'subfecund', 'subfecundity', 'treatment', 'help-seeking', 'service use', 'service utilization', 'ART use' and 'MAR use' separately and in various combinations. The focus was on studies from developed countries, published between 1990 and 2018, in English, German or French.

OUTCOMES

In this article, we have reviewed 39 studies covering 13 countries or regions; approximately half of these covered the USA. Ten studies were published in the 1990s, 10 in the 2000s and 19 since 2010. Studies report different types of prevalence rates such as lifetime and current prevalence rates of MAR use. Prevalence rates are based on very different denominators: women who tried to become pregnant for at least 12 months without success, women who experienced at least 12 months of unprotected intercourse without success, women of reproductive age from the general population or women with a life birth. There are few studies that report help-seeking rates for men or make direct comparisons between genders. Knowledge on medical help-seeking across different stages, such as seeing a doctor, undergoing tests, having operations to restore fertility or ART, has started to accumulate in recent years. There are conceptual reasons for being cautious about drawing conclusions about gender, regional, country level and differences over time in help-seeking rates.

LIMITATIONS REASONS FOR CAUTION

In a narrative review, the risk of bias in the interpretation of findings cannot be completely eliminated. The literature search was limited to languages the authors speak: English, French and German.

WIDER IMPLICATIONS

In line with earlier reviews, we found that studies on help-seeking are not comparable across time and space, preventing researchers and healthcare providers from understanding the relation between social change, social policy, social structure and help-seeking for infertility. The discussion in this article should assist future researchers in designing better studies on the prevalence of MAR use. We provide suggestions for producing better estimates of the prevalence of MAR use. More cross-country and cross-gender comparisons are needed. Studies that treat help-seeking as a continuum and report on different stages are preferable compared to choosing arbitrary cutoff points, as is common practice in the studies reviewed.

The association of types, intensities and frequencies of physical activity with primary infertility among females in Gaza Strip, Palestine: A case-control study

INTRODUCTION

Physical activity and energy state balance have fundamentally been related to reproductive system and health. This study explored the relationship between different types, intensities and frequencies of physical activity with primary infertility among women in Gaza Strip, Palestine.

METHODS

A case-control study was conducted in Gaza Strip with the participation of 320 married couples. 160 infertile couples were chosen from five fertility centers registries from 2016 to 2018 and matched residentially with 160 fertile couples. Cases were selected through systematic stratified sampling of five lists categorized according to residency and the determined percentage selected from each list was proportional. Data were collected through a self-administered questionnaire extended by the short form of international physical activity questionnaire and analyzed through SPSS program version 22 by using descriptive analysis, independent T-test, cross-tabulation, and binary logistic regression.

RESULTS

Low frequency, intensity and duration of physical activity were associated with 3.1 risk of primary infertility (95% CI, 1.60-5.99, P < 0.001). Adjustment for age, marital age, age of menarche, refugee status and monthly income provided 3.2 risk (95% CI, 1.55-6.60, P = 0.002). Women spending more than 300 minutes a day sedentarily were 2.3 times more likely to have fertility problems than physically active females. Measuring energy expenditure in MET-min/w (Metabolic Equivalent) showed vigorous MET-min/w as negatively associated with the infertility status of females (Interquartile range IQR: 480 for cases and 720 for controls, P = 0.010). On the basis of energy expended in kilocalories in relation to weight, results showed the same association (IQR: 564 for case and 864 for controls, P = 0.011). No associations were found between moderate activity levels and primary infertility.

CONCLUSION

Low levels of physical activity and sedentary lifestyle endanger the fertility status of females in Gaza Strip. This may offer the need for endorsing and formalizing adequate physical activity education and awareness protocols in the national reproductive health guidelines and empowering environmental capacity building to alter physical activity-related cultural norms.

Risk Factors, Imaging Findings, and Sex Differences in Spontaneous Coronary Artery Dissection

Spontaneous coronary artery dissection (SCAD) is increasingly being recognized. However, data supporting diagnosis and management are scarce. We analyze a contemporary and comprehensive SCAD registry to advance the understanding of SCAD risk factors, angiographic appearance, and gender differences. This is a retrospective analysis of a prospectively populated database of SCAD patients seen at the Massachusetts General Hospital (MGH) between June 2013 and October 2017. Core laboratory analysis of both coronary angiograms and computerized tomographic (CT) angiography of the extracoronary vessels was performed. Of the 113 patients, 87% were female and mean age was 47 ± 10 years. Traditional cardiovascular risk factors including hypertension, hyperlipidemia, and smoking were present in 27%, 14%, and 22% of patients. Among females, 14%, 8%, and 9% had a history of gestational hypertension, pre-eclampsia, and gestational diabetes, respectively. Fifteen percent had used fertility treatment and 47% of postmenopausal women had used hormone replacement therapy. Angiography showed multivessel SCAD in 42%, severe coronary artery tortuosity in 59%, and extracoronary vascular abnormalities in 100% of patients with complete CT angiographic imaging. Gender differences revealed a self-reported depression and anxiety prevalence of 20% and 32%, respectively, in women compared with 0% in men. Type 1 SCAD was more commonly diagnosed in men than women (71% vs 29%, p <0.01). In conclusion, we highlight under-recognized features of SCAD including (1) relation with pregnancy complications and exposure to hormonal therapy; (2) diffuse, multivessel process in tortuous coronaries on a background of extracoronary arterial abnormalities; and (3) gender differences highlighting the role of mental health as well as potential underdiagnoses in men.

The impact of maternal lifestyle factors on periconception outcomes: a systematic review of observational studies

The main risk factors for important reproductive health issues such as subfertility and perinatal mortality largely originate in the periconception period. To evaluate associations between modifiable maternal lifestyle factors and periconception outcomes, a systematic search was conducted for relevant studies published from 1990 to February 2017 on Embase, Medline, Web of Science, Cochrane database, PubMed and Google Scholar. The initial search identified 6166 articles, of which 49 studies were eligible for inclusion. Fecundity (the capacity to have a live birth) showed significant inverse associations with smoking, alcohol use and poor diet. Studies regarding time to pregnancy showed a decline in fecundity ratios (the monthly conception rate among exposed relative to unexposed couples) with increasing body mass index (BMI). Furthermore, risk of first-trimester miscarriage was found to be increased in smokers, alcohol and caffeine consumers, and with increasing BMI. Vitamin supplement use showed a decrease in this risk. This review demonstrates that maternal modifiable lifestyle factors affect periconception outcomes. If couples planning a pregnancy are more aware and supported to adopt healthy lifestyles during the periconceptional 'window of opportunity', short-term reproductive health as well as health in later life and even of future generations can be further improved.
