The impact of infertility on men's work and finances: Findings from a qualitative questionnaire study

Reduced human fecundity attributable to ambient fine particles in low- and middle-income countries

BACKGROUND

Exposure to ambient fine particulate matter (PM2.5) has been associated with reduced human fecundity. However, the attributable burden has not been estimated for low- and middle-income countries (LMICs), where the exposure-response function between PM2.5 and the infertility rate has been insufficiently studied.

OBJECTIVE

This study examined the associations between long-term exposure to PM2.5 and human fecundity indicators, namely the expected time to pregnancy (TTP) and 12-month infertility rate (IR), and then estimated PM2.5-attributable burden of infertility in LMICs.

METHODS

We analyzed 164,593 eligible women from 100 Demographic and Health Surveys conducted in 49 LMICs between 1999 and 2021. We assessed PM2.5 exposures during the 12 months before a pregnancy attempt using the global satellite-derived PM2.5 estimates produced by Atmospheric Composition Analysis Group (ACAG). First, we created a series of pseudo-populations with balanced covariates, given different levels of PM2.5 exposure, using a matching approach based on the generalized propensity score. For each pseudo-population, we used 2-stage generalized Gamma models to derive TTP or IR from the probability distribution of the questionnaire-based duration time for the pregnancy attempt before the interview. Second, we used spline regressions to generate nonlinear PM2.5 exposure-response functions for each of the two fecundity indicators. Finally, we applied the exposure-response functions to estimate number of infertile couples attributable to PM2.5 exposure in 118 LMICs.

RESULTS

Based on the Gamma models, each 10 µg/m3 increment in PM2.5 exposure was associated with a TTP increase by 1.7 % (95 % confidence interval [CI]: -2.3 %-6.0 %) and an IR increase by 2.3 % (95 %CI: 0.6 %-3.9 %). The nonlinear exposure-response function suggested a robust effect of an increased IR for high-concentration PM2.5 exposure (>75 µg/m3). Based on the PM2.5-IR function, across the 118 LMICs, the number of infertile couples attributable to PM2.5 exposure exceeding 35 µg/m3 (the first-stage interim target recommended by the World Health Organization global air quality guidelines) was 0.66 million (95 %CI: 0.061-1.43), accounting for 2.25 % (95 %CI: 0.20 %-4.84 %) of all couples affected by infertility. Among the 0.66 million, 66.5 % were within the top 10 % high-exposure infertile couples, mainly from South Asia, East Asia, and West Africa.

CONCLUSION

PM2.5 contributes significantly to human infertility in places with high levels of air pollution. PM2.5-pollution control is imperative to protect human fecundity in LMICs.

Lived Experiences of Fatherhood After Infertility

OBJECTIVE

To explore the lived experiences of fathers in the perinatal period after infertility.

DESIGN

A descriptive, phenomenological study.

SETTING

Researcher's private office and participants' homes in an Eastern Canadian province.

PARTICIPANTS

Eight fathers who met the eligibility criteria.

METHODS

We recruited a purposive sample of eight participants and held one-on-one interviews in person, by telephone, and via virtual platforms. We analyzed the verbatim transcripts of the audiotaped interviews using Colaizzi's phenomenological data analysis method.

RESULTS

We uncovered seven themes that described the lived experiences of participants: The Journey: A Long Winding Road, Roles and Responsibilities: Supporter and Protector, Support: The Often-Forgotten Parent, Challenges and Hurdles: Bumps on the Road, So Many Feelings: The Rollercoaster, Coping: Living on the Road, and Reflection: An Unforgotten Journey. Participants shared their experiences of the perinatal period after infertility as long journeys and described how bumps along the road marked these journeys. The journeys were essential parts of their lives that they continued to remember years later.

CONCLUSION

The perinatal experience after infertility is an important and remembered time for fathers. It is essential to involve and support them in the perinatal process to facilitate positive experiences and overall family health, especially after infertility. There is an ongoing need to conduct research with fathers and to develop evidence-based programming and resources to assist them in the perinatal period after infertility.

Exploring men's struggles with infertility: A qualitative content analysis

AIM

To investigate the experiences of men struggling with infertility.

DESIGN

This is a qualitative study, and the report follows the COREQ checklist.

METHODS

A team of nurse researchers conducted this research in Iran to examine the experiences of 11 men with primary infertility. The participants were selected through targeted sampling and underwent in-depth semi-structured interviews. The data collected was analysed using the conventional content analysis method outlined by Krippendorff. To ensure the study's accuracy, it followed the criteria proposed by Lincoln and Guba.

RESULTS

The central theme, "the threat to masculinity," was identified upon analysis. It comprises six categories: psychological pressure of confronting reality, frustration, discomfort with others, holding out against ridicule, tolerating unwanted opinions and advice and concealment of infertility and therapy.

CONCLUSION

This study brings attention to the challenge to masculinity that men with primary infertility face as their central struggle. It highlights the importance of culturally sensitive care from healthcare professionals, emotional support, counselling services and public awareness to reduce the stigma surrounding male infertility. It can be valuable to evaluate and enhance infertility care in various settings.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

To provide the best possible care for infertile men, it would be beneficial for nurses to pay more attention to sociocultural factors. Fertility care should be respectful of patients' beliefs and backgrounds.

IMPACT

WHAT PROBLEM DID THE STUDY ADDRESS?: Infertility care has been the subject of recent research, focusing on the impact of sociocultural factors. Male-factor infertility is often overlooked in clinical care literature. There is a correlation between cultural background and men's acceptance of reproductive healthcare. WHAT WERE THE MAIN FINDINGS?: Male infertility is often avoided in discussions due to its perceived threat to masculinity. Multiple factors, including societal norms, cultural expectations and personal experiences, influence the nature of men's struggles with infertility. Providing emotional support and counselling services is crucial so that men can openly discuss their fertility challenges and seek treatment without feeling ashamed or judged. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: Raising public awareness and providing education about male infertility is crucial. Nurses must exhibit cultural sensitivity while caring for men experiencing infertility. Policymakers need to implement strategies to reduce the stigma surrounding male infertility.

REPORTING METHOD

The study is reported using the Consolidated Criteria for Reporting Qualitative Research (COREQ).

PATIENT OR PUBLIC CONTRIBUTION

No public or patient involvement.

Survey dataset on occupational stress, job satisfaction, and job performance among male fertility patients

This article presents data on occupational stress, job satisfaction, and job performance among male fertility patients. The data were collected from 11 November 2021 until 30 October 2022. A quantitative research approach was employed, involving a questionnaire development and survey. A sample of 309 was selected, using simple random sampling, from the pool of male patients that had undergone seminal fluid analysis (SFA) and received treatment from four private fertility clinics in Malaysia. Respondents were asked to give their consent by signing a consent form, for ethical research purposes. The questionnaire asked respondents about their demographics, sperm quality, occupational stress, job satisfaction, and job performance. The data could help other researchers to develop research on management issue in the context of male fertility, as well as organisations to maintain the health and welfare of their employees.

Tissue engineering studies in male infertility disorder

Infertility is an important issue among couples worldwide which is caused by a variety of complex diseases. Male infertility is a problem in 7% of all men. In vitro spermatogenesis (IVS) is the experimental approach that has been developed for mimicking seminiferous tubules-like functional structures in vitro. Currently, various researchers are interested in finding and developing a microenvironmental condition or a bioartificial testis applied for fertility restoration via gamete production in vitro. The tissue engineering (TE) has developed new approaches to treat male fertility preservation through development of functional male germ cells. This makes TE a possible future strategy for restoration of male fertility. Although 3D culture systems supply the perception of the effect of cellular interactions in the process of spermatogenesis, formation of a native gradient of autocrine/paracrine factors in 3D culture systems have not been considered. These results collectively suggest that maintaining the microenvironment of testicular cells even in the form of a 3D-culture system is crucial in achieving spermatogenesis ex vivo. It is also possible to engineer the testicular structures using biomaterials to provide a supporting scaffold for somatic and stem cells. The insemination of these cells with GFs is possible for temporally and spatially adjusted release to mimic the microenvironment of the in situ seminiferous epithelium. This review focuses on recent studies and advances in the application of TE strategies to cell-tissue culture on synthetic or natural scaffolds supplemented with growth factors.

Prevalence of depression in infertile men: a systematic review and meta-analysis

BACKGROUND

Generally, infertile men hide their depression, which can threaten their health and lower their quality of life. Given the role of depression and its impact on people's health, this systematic review and meta-analysis aimed to investigate the prevalence of depression in infertile men.

METHODS

This research is a systematic review and meta-analysis based on preferred reporting items for systematic reviews and meta-analyses (PRISMA). Using the keywords of "Depression", "Emotional Depression", "Infertility", "Prevalence", and "Epidemiology", all English language articles were searched in international databases (PubMed, Cochran library, Web of sciences, Scopus, Embase, PsyINFO, and Google scholar) by two reviewers independently and without considering the time limit until September 2022. Title, abstract, full text and quality of each study were evaluated by two reviewers independently using the Newcastle-Ottawa Scale checklist. The results were analyzed using programming language and R software, and I2 test and Egger's Test were used to check heterogeneity and publication bias, respectively.

RESULTS

Twenty-two studies were included in the systematic part of this study; and 8 different measurement tools were used to identify depression. Then, based on the possibility of meta-analysis, 18 studies were included in 4 subgroups. Given the heterogeneity of the articles, random effect model was used. The overall prevalence of depression in infertile men was 18.30%. The lowest and highest overall prevalence of depression in men was reported to be 14.04% and 23.63% in the Zung Self-Rating Depression Scale (ZDS) and the Depression Anxiety Stress Scales (DASS) tools, respectively. The overall prevalence of depression among infertile men was reported to be 18.55% and 16.75% using the Beck Depression Inventory (BDI) and the Hospital Anxiety and Depression Scale (HADS) tools, respectively.

CONCLUSION

Based on the findings of this study, the significant prevalence of depression in infertile men requires a specific attention and planning. The study revealed varying degrees of depression among infertile men, emphasizing the importance of assessing their mental health, specifically in terms of depression, during infertility treatments as a hidden variable. It is strongly recommended to develop training programs for health service providers to effectively utilize diagnostic tools in this particular field.

How fear of intimacy affects infertile men's neuropsychological functioning through mental toughness

OBJECTIVE

There is a significant need in Pakistan to investigate the psychological effects of infertility on the mental health of infertile men. The current study examined how fear of intimacy affects neuropsychological impairment and evaluated its relationship to other variables including quality of life and mental toughness.

METHOD

An analytical cross-sectional study was carried out on infertile male patients in various healthcare settings in Punjab, Pakistan. The participants were recruited using a non-probability (purposive) sampling strategy. The sample size was 120 infertile. SPSS 26 was used to analyze the data.

RESULTS

Fear of intimacy was found significant impact on neuropsychological impairment (r = 0.40; ***p < 0.001), as well as fear of intimacy, significantly associated with emotional problems (r = 0.48; **p < 0.01), learning problems (r = 0.33; **p < 0.01), sensory and motor problem (r = 0.55; **p < 0.01), concentration problem (r = 0.21; **p < 0.01), mental & physical in coordination (r = 0.37; **p < 0.01) and depression (r = 0.22; **p < 0.01). Fear of intimacy has negative impact on QoL (r = -0.25; *p > 0.05). Similarly, neuropsychological impairment was found to be negatively associated with QoL (r = -0.52; **p > 0.01). The relationship between fear of intimacy and neuropsychological impairment was found to be significantly mediated by QoL. Furthermore, the findings revealed that mental toughness significantly moderated the relationship between fear of intimacy and neuropsychological impairment.

CONCLUSION

Overall, infertile men in Pakistan had relatively high levels of fear of intimacy, which largely caused neuropsychological impairment. This study can help neuropsychological researchers, mental health professionals, as well as policymakers in improving clinical mental health practices for infertile patients.

Mitochondrial succinate dehydrogenase function is essential for sperm motility and male fertility

Mitochondrial health is crucial to sperm quality and male fertility, but the precise role of mitochondria in sperm function remains unclear. SDHA is a component of the succinate dehydrogenase (SDH) complex and plays a critical role in mitochondria. In humans, SDH activity is positively correlated with sperm quality, and mutations in SDHA are associated with Leigh Syndrome. Here we report that the C. elegans SDHA orthologue SDHA-2 is essential for male fertility: sdha-2 mutants produce dramatically fewer offspring due to defective sperm activation and motility, have hyperfused sperm mitochondria, and disrupted redox balance. Similar sperm motility defects in sdha-1 and icl-1 mutant animals suggest an imbalance in metabolites may underlie the fertility defect. Our results demonstrate a role for SDHA-2 in sperm motility and male reproductive health and establish an animal model of SDH deficiency-associated infertility.
