Men's knowledge of their own fertility: a population-based survey examining the awareness of factors that are associated with male infertility

A systematic review of interventions to improve male knowledge of fertility and fertility-related risk factors

Male infertility is a global health concern. The effectiveness of interventions developed to improve males' knowledge of fertility regulation and fertility-related risk factors remains unclear. This systematic review aimed to synthesize and evaluate the evidence for these interventions. Four databases were searched from inception to June 2023. Eligible studies examined interventions to increase fertility knowledge among presumed fertile males aged ≥16 years of age. Conference abstracts, protocols and studies without sex-disaggregated results for males were excluded. A narrative synthesis without meta-analysis was performed. A total of 4884 records were identified. Five studies (reported in six publications), all conducted in high-income countries, were included. Two were randomized control trials, and three were experimental studies. Interventions were delivered in person by a health professional (n = 3), online and via a mobile app. All studies showed a significant improvement in knowledge of fertility or fertility-related risk factors from baseline to follow-up. The largest improvement was observed for secondary and vocational students. A moderate, long-term retainment of knowledge was observed at two-year follow-up in one study. Available evidence suggests interventions to improve males' fertility knowledge are effective, particularly for younger, less educated males.

Current global status of male reproductive health

BACKGROUND

The widespread interest in male reproductive health (MRH), fueled by emerging evidence, such as the global decline in sperm counts, has intensified concerns about the status of MRH. Consequently, there is a pressing requirement for a strategic, systematic approach to identifying critical questions, collecting pertinent information, and utilizing these data to develop evidence-based strategies. The methods for addressing these questions and the pathways toward their answers will inevitably vary based on the variations in cultural, geopolitical, and health-related contexts. To address these issues, a conjoint ESHRE and Male Reproductive Health Initiative (MRHI) Campus workshop was convened.

OBJECTIVE AND RATIONALE

The three objectives were: first, to assess the current state of MRH around the world; second, to identify some of the key gaps in knowledge; and, third, to examine how MRH stakeholders can collaboratively generate intelligent and effective paths forward.

SEARCH METHODS

Each expert reviewed and summarized the current literature that was subsequently used to provide a comprehensive overview of challenges related to MRH.

OUTCOMES

This narrative report is an overview of the data, opinions, and arguments presented during the workshop. A number of outcomes are presented and can be summarized by the following overarching themes: MRH is a serious global issue and there is a plethora of gaps in our understanding; there is a need for widespread international collaborative networks to undertake multidisciplinary research into fundamental issues, such as lifestyle/environmental exposure studies, and high-quality clinical trials; and there is an urgent requirement for effective strategies to educate young people and the general public to safeguard and improve MRH across diverse population demographics and resources.

LIMITATIONS REASONS FOR CAUTION

This was a workshop where worldwide leading experts from a wide range of disciplines presented and discussed the evidence regarding challenges related to MRH. While each expert summarized the current literature and placed it in context, the data in a number of areas are limited and/or sparse. Equally, important areas for consideration may have been missed. Moreover, there are clear gaps in our knowledge base, which makes some conclusions necessarily speculative and warranting of further study.

WIDER IMPLICATIONS

Poor MRH is a global issue that suffers from low awareness among the public, patients, and heathcare professionals. Addressing this will require a coordinated multidisciplinary approach. Addressing the significant number of knowledge gaps will require policy makers prioritizing MRH and its funding.

Frequency, morbidity and equity - the case for increased research on male fertility

Currently, most men with infertility cannot be given an aetiology, which reflects a lack of knowledge around gamete production and how it is affected by genetics and the environment. A failure to recognize the burden of male infertility and its potential as a biomarker for systemic illness exists. The absence of such knowledge results in patients generally being treated as a uniform group, for whom the strategy is to bypass the causality using medically assisted reproduction (MAR) techniques. In doing so, opportunities to prevent co-morbidity are missed and the burden of MAR is shifted to the woman. To advance understanding of men's reproductive health, longitudinal and multi-national centres for data and sample collection are essential. Such programmes must enable an integrated view of the consequences of genetics, epigenetics and environmental factors on fertility and offspring health. Definition and possible amelioration of the consequences of MAR for conceived children are needed. Inherent in this statement is the necessity to promote fertility restoration and/or use the least invasive MAR strategy available. To achieve this aim, protocols must be rigorously tested and the move towards personalized medicine encouraged. Equally, education of the public, governments and clinicians on the frequency and consequences of infertility is needed. Health options, including male contraceptives, must be expanded, and the opportunities encompassed in such investment understood. The pressing questions related to male reproductive health, spanning the spectrum of andrology are identified in the Expert Recommendation.

The pros and cons of fertility awareness and information: a generational, Swedish perspective

Being aware of factors that affect fertility can help people make informed decisions about their reproductive futures. To some, however, fertility information leads to worry and self-blame. In this paper, we explore how people from different generations discuss fertility and reproductive decision-making, along with their perceptions of fertility information. The study was conducted in southern Sweden with 26 focus-group discussions that included a total of 110 participants aged 17-90 years. The material was analysed thematically. Our results show that fertility knowledge and openness to talking about fertility problems have increased over generations. Participants who were assigned female at birth were more often concerned about their fertility than those who were not, and fertility concerns were transferred from mothers to daughters. While age-related fertility concerns had been uncommon in older generations, participants aged 25-40 often expressed these concerns. Young adults appreciated being knowledgeable about fertility but simultaneously expressed how fertility information could lead to distress. Our conclusion is that fertility information was best received by high-school students, and efforts to improve fertility education in schools are therefore recommended.

Association between Hidradenitis Suppurativa and Abnormalities in Semen Parameters and Sexual Function: A Pilot Study

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting patients of reproductive age. Although HS shares risk factors with male infertility, only 1 epidemiological study has evaluated this association. To further evaluate this potential association, findings on semen and hormonal analysis, testicular ultrasound, and the International Index of Erectile Function (IIEF-15) were compared between 28 men attending a tertiary HS clinic during the period April 2019 to April 2021, and 44 healthy controls, spouses of infertile women undergoing semen evaluation before in vitro fertilization. Patients with HS were divided based on the absence or presence of gluteal and genital lesions. Patients with HS were younger than controls (median 27 vs 34 years, p < 0.0004) and had a higher proportion of smokers (86% vs 33%, p < 0.0001). Semen parameters in patients with gluteal-genital lesions, specifically those with severe scrotal involvement necessitating surgery, were lower than the WHO reference values and significantly lower than in patients without gluteal-genital lesions and controls. Erectile dysfunction was reported by 93% of patients with HS. These findings suggest that spermatogenesis and sexual function may be impaired in young men with HS. Therefore, multidisciplinary management of HS should include their evaluation to identify patients who might benefit from semen cryopreservation and sexual treatment.

"No One Asked Me If I'm Alright": A Mixed-Methods Study Exploring Information/Support Needs and Challenges Engaging Men Diagnosed With Male-Factor Infertility

There is limited research exploring men's experiences of infertility, and fewer previous studies have examined what information and support men desire after being diagnosed specifically with male-factor infertility. We conducted a mixed-methods study utilizing a combined sequential, concurrent design (online survey/semi-structured interviews). Survey outcomes (N =12) were analyzed using quantitative data analysis, while qualitative survey data (N = 5) was analyzed by reflexive thematic analysis. Heterosexual men (>18 years), fluent in English, diagnosed solely with male-factor infertility/sub-fertility, who required assisted reproductive treatment within Australia in the past 5 years were recruited online and through fertility clinics Australia-wide. Most men reported that their information and support needs were only somewhat, slightly or not at all met. Preferred information sources on male infertility were a dedicated online resource, app, or fertility doctor/specialist, while support was preferred from fertility specialists and partners. Three themes were identified from the qualitative analysis about men's experiences and support needs when diagnosed with male infertility (a) Ultimate threat to masculinity; (b) Holistic care, and (c) the power of words. The information-rich data collected provided valuable insights into men's experiences of male-factor infertility and important considerations to improve recruitment for future research. A diagnosis of male-factor infertility has the potential to be deeply impactful and difficult to navigate for men. Adequate and holistic information, recognition of emotional impacts, proactive offers of support and sensitive language are needed to improve men's experiences when undergoing assisted reproductive technology.

Infertility and perceived chance of conception among men in Malawi

Infertility is a common experience among individuals and couples worldwide, but few studies focus on men's reports of infertility or perceived chance of conceiving, particularly in high-fertility, pronatalist contexts where infertility is highly stigmatized. Using data from the fourth wave of the Umoyo wa Thanzi (UTHA) cohort study in rural Central Malawi (2017-2018), we examine the relationship between self-reported infertility, the perceived chance of conceiving within one year, and sociodemographic characteristics among men (N = 484). While 13% of men reported that they had experienced infertility, just 4% of men perceived that they were unlikely or there was no chance they would conceive with their partner within one year of having sex without contraception. In multivariable logistic regression models, older age was associated with experienced infertility (AOR: 1.06, p < 0.05) and higher parity was associated with lower odds of reporting that conception was unlikely or there was no chance of conception (AOR: 0.08; p < 0.05). We argue that additional research on infertility focusing on men is critical in gaining a more holistic and gender-equitable understanding of infertility. Including men in infertility research may also contribute to destigmatizing infertility among both women and men by acknowledging men's roles in infertility.

Tobacco and alcohol as factors for male infertility-a public health approach

BACKGROUND

The study of reproductive characteristics of 430 male subjects of different age, fertility status and educational level who were involved in the program of extracorporeal fertilization at the Clinic of Gynecology and Obstetrics, Clinical Centre Niš, examined their knowledge, attitudes and behavior regarding tobacco and alcohol consumption as lifestyle risk predictors of their partial or full infertility.

METHODOLOGY

Consisted of the analyses of spermiograms to establish their fertility status and a survey of their attitudes towards smoking and alcohol use (behavior, knowledge of the general health and reproductive health consequences of such a lifestyle, and their determination to change it).

RESULTS

The proportion with higher tobacco consumption and more severe forms of infertility increased significantly with ageing (P < 0.001); the highest daily consumption of alcohol and the incidence of intoxication was seen among azoospermic patients; the level of awareness of the harmful effects of tobacco was highest among normozoospermic subjects and the highest level of determination to quit smoking was statistically significantly present among azoospermic subjects.

CONCLUSION

Appropriate use of health promotion activities in relation to alcohol and tobacco use is through specially designed programs.

Impact of waterpipe and tobacco cigarette smoking on global DNA methylation and nuclear proteins genes transcription in spermatozoa: a comparative investigation

BACKGROUND

Waterpipe smoking is harmful and dangerous, and it is a growing threat to public health.

OBJECTIVES

This study was performed to evaluate the influence of waterpipe smoking on global DNA methylation, DNA fragmentation, and protamine deficiency in spermatozoa compared to cigarette heavy smokers and nonsmokers, and to determine whether the transcription levels of spermatozoa nuclear proteins genes 'PRM1, PRM2, and H2BFWT' in waterpipe smokers are different compared to cigarette heavy smokers and nonsmokers.

METHODS

A total of 900 semen samples were collected from males with a mean age of 32.5 ± 6.3 years (300 waterpipe smokers, 300 cigarette heavy smokers, and 300 nonsmokers). The nucleic acids were isolated from purified spermatozoa, and then the global DNA methylation and transcription levels of the PRM1, PRM2, and H2BFWT genes were assessed using ELISA and qPCR, respectively.

RESULTS

A significant increase was found in the level of global DNA methylation (8.6 ± 0.6 ng/μl vs. 7.1 ± 0.6 ng/μl and 4.7 ± 0.6 ng/μl, p < 0.001), protamine deficiency (72.8 ± 15.3 vs. 51.7 ± 19.2 and 15.3 ± 5.9%, p < 0.001), and DNA fragmentation (73.4 ± 13.4 vs. 50.5 ± 18.9 and 9.3 ± 4.3%, p < 0.001) in waterpipe smokers compared to cigarette heavy smokers and nonsmokers. A significant increase was shown in the transcription levels of PRM1, PRM2, and H2BFWT genes in waterpipe smokers compared to cigarette heavy smokers and nonsmokers (p < 0.001). A down-regulation was found in the transcription level of these genes in different smoker groups compared to nonsmokers (<0.001).

CONCLUSION

This study suggests that waterpipe smoking is more harmful than cigarette smoking on semen parameters, global DNA methylation, and transcription of nuclear protein genes.

Undergraduate students have low fertility knowledge and high anxiety regarding future fertility: An opportunity for education

Objectives

To assess childbearing intentions, concerns about future fertility, knowledge about the age-related decline in fertility, and interest in receiving fertility education among undergraduate students.

Design

From March to April 2021, a cross-sectional, web-based survey with 42 reproductive and fertility-related questions was administered to and completed by actively enrolled undergraduates at Northwestern University in the United States.

Results

The survey was completed by 291 students (mean age 20.2 years). Of all participants, 62.5% plan to have children and 68.3% intend to delay childbearing. Significantly more females than males (70.7% vs 40.9%, P = 0.004) and premedical students compared to non-premedical students (78.2% vs 60.1%, P = 0.002) reported planning to delay childbearing due to educational or career aspirations. Significantly more females than males (43.5% vs 4.5%, P < 0.001) and premedical compared to non-premedical students (50.4% vs 31.5%, P = 0.002) also reported having anxiety about future fertility due to career aspirations.When surveyed about fertility knowledge, 31.1% of participants reported that females are as fertile in their forties as they are in their thirties, and 25.4% stated that female fertility does not dramatically decline until age 40 or later. When asked to estimate the oldest age a woman has conceived using autologous oocytes, 83.3% reported age 48 or older. Of all participants, 72.3% were interested in learning about fertility.

Conclusions

The majority of surveyed undergraduates plan to delay childbearing, yet they have concerns about how career goals will impact future fertility. Notably, females and premedical students reported higher rates of anxiety when compared to their male and non-premedical counterparts. Knowledge about the age-related decline in fertility was limited, but students have a strong interest in learning about fertility, highlighting an opportunity for educational intervention at the undergraduate level. With education, students may be empowered to make informed decisions about future reproductive strategy earlier in time, potentially decreasing future anxiety.

A mixed methods study investigating sources of fertility and reproductive health information in the UK

OBJECTIVES

This study aimed to assess the different sources used by individuals when seeking fertility information in order to understand what's working, what isn't, and opportunities for improvement.

METHODS

A mixed-method study was conducted via UK-wide cross-sectional survey and semi-structured interviews. 1082 survey-participants were recruited nationwide via online-newspaper and social-media adverts. Of those who agreed to follow-up interview, 35 were purposively sampled to reflect the diversity of gender, age-range, ethnicity and education. Tableau software was used for surveys and NVIVO for interviews. Interview data was transcribed and analysed via thematic framework analysis.

RESULTS

Sources of information identified included: school-education; healthcare-professionals; internet, social-media, smartphone-apps, online-forums and blogs; family, friends, and communities; books, magazines, newspapers; fertility-products; workplace, communities and sexual-health clinics/centres, charities, and third-party organisations. Participants reported varying levels of access, reliability, and trust, in relation to these sources. Interview themes around veracity showed that healthcare-professionals were highly trusted but not easily accessible. The internet was very popular due to accessibility and perceived anonymity but untrusted, and "the plethora of information can be overwhelming." There were recurring themes around discomfort. A respondent recalled that her first discussion of sex with her mother was on her wedding night stating, "…Mum, I'm 28! And you're just discussing this with me now?"

CONCLUSIONS

School education remains a consistent but sometimes inadequate source of fertility information. In addition to online-platforms and products based on robust scientific evidence, opportunities for improvement include using underexploited sources, such as workplace and community settings, with training for providers.

Effect of hubble-bubble smoking on global DNA methylation and transcription levels of protamine and histone genes in human spermatozoa

This study was conducted to assess the impact of hubble-bubble smoking on global DNA methylation, DNA fragmentation; protamine deficiency of spermatozoa, and to determine whether the transcription levels of the protamine and histone genes are different in hubble-bubble smokers compared to nonsmokers. Five hundred semen samples were collected from males with an average age of 32.2 ± 6.1 years (300 hubble-bubble smokers "60%" and 200 nonsmokers "40%"). The nucleic acid was isolated from purified sperm, then ELISA and qPCR were used to evaluate the global DNA methylation and transcription level of protamine and histone, respectively. A significant elevation in global DNA methylation, protamine deficiency, and DNA fragmentation was found in hubble-bubble smokers compared to nonsmokers (P < 0.0001). A significant decline was shown in transcription levels of protamine and histone genes in hubble-bubble compared to nonsmokers (P < 0.0001). Additionally, a down-regulation in the transcription levels of protamine and histone was revealed in hubble-bubble compared to nonsmokers with fold change (0.0001 and 0.007, respectively). In conclusion, this study provided proof that hubble-bubble smoking has a negative impact on global DNA methylation, DNA fragmentation, protamine deficiency, and the transcription of protamine and histone genes in spermatozoa, and these findings influence negatively males' fecundity.

Knowledge, attitude and perception among medical students and healthcare professionals regarding male infertility: a cross-sectional survey from Bangladesh

OBJECTIVE

This study aimed to explore the knowledge, attitude and behaviour regarding male infertility among medical students and healthcare workers in Bangladesh.

DESIGN

This was a cross-sectional study.

SETTING

This study covered eight divisions of Bangladesh.

PARTICIPANTS

The participants were medical students or healthcare professionals of Bangladesh who were surveyed anonymously on their knowledge, attitude and perception regarding male infertility.

PRIMARY OUTCOME MEASURES

The level of knowledge, attitude and perception regarding male infertility.

ANALYSIS

The mean knowledge and attitude scores were then correlated with sociodemographic factors using χ² and two-independent sample t-tests. Finally, we performed binary logistic regression to explore predictors of good knowledge and positive attitude.

RESULT

Among 556 participants, 49.82% did not have good male infertility knowledge, and nearly 60.79% had negative attitudes regarding male infertility. Young (23-26 years) healthcare professionals and medical students were more likely to have good knowledge than others (OR: 1.81; 95% CI 1.099 to 2.988). Surprisingly, women were more likely to have a positive attitude (OR=1.48; 95% CI 1.002 to 2.19, p=0.049) than men. Among all the professions, Bachelor of Medicine and Surgery doctors were most likely to have good knowledge and a positive attitude regarding male infertility. Good knowledge of male infertility predicted a positive attitude (OR=1.61; 95% CI 1.105 to 2.346, p=0.013) and vice versa.

CONCLUSION

Our research found that healthcare professionals and medical students in Bangladesh had inadequate knowledge and negative attitudes regarding male infertility despite favourable opinions. This emphasises the need for interdisciplinary training programmes, standardisation of healthcare worker guidelines and curricular adjustments for medical students.

A systematic review on the effectiveness of herbal interventions for the treatment of male infertility

Background: Male infertility is an emerging health issue in the world today. Surgical interventions for the treatment of male infertility are available but are quite expensive. Herbal interventions pose a popular alternative for the treatment of infertility. However, much has to be learned regarding their safety and efficacy. Objective: The aim of the study was to investigate the efficacy of herbal interventions in male infertility and also assess the possibility of these interventions as complementary and alternative medicine (CAM) in the future. Method: From inception until 16 December 2021, all articles emphasizing the efficacy of herbal interventions in the treatment of male infertility are included in this review. Seven databases are searched. The literature obtained is screened and extracted. Semen parameters, hormonal concentration, and conception are the outcomes of interest. Results: A total of 19 articles were included in this review. Herbal interventions might improve semen parameters in males with infertility. Among all the interventions, Hochu-ekki-to and W. somnifera have shown the most promising results and should be studied further in a larger sample size. Conclusion: This systematic review has demonstrated the efficacy of herbal interventions, especially Hochu-ekki-to and W. somnifera, in treating male infertility.

Fertility Health Knowledge in U.S. Adults: Men Narrowing the Knowledge Gap

Much of young people's fertility health knowledge has been limited to avoiding sexually transmitted infections and preventing pregnancy thus lacking what is necessary to support future overall health as well as reproductive goals. This study assesses university students' knowledge related to fertility health factors to verify consistencies and discrepancies in fertility health knowledge, with a sub-assessment focusing on men's knowledge. The Fertility Health Knowledge survey was delivered to 17,189 students at three American universities. Twenty percent or 546 of the 2,692 participants were male. The 30-question survey addresses knowledge of modifiable and non-modifiable risk factors on fertility health in men and women, and four questions regarding fertility intentions. Across all 30 questions, 63% of female responses were correct and 61% of male responses were correct. For 10 questions, less than 70% of males and females answered correctly, with men answering correctly more often than females for six of the questions. Males exhibited more knowledge regarding male fertility. Knowledge of fertility health was consistently limited, regardless of site or demographics. Men demonstrated improved overall fertility health knowledge and more knowledge regarding male factors. There are still considerable gaps in knowledge of modifiable risk factors that may impact fertility health and future overall health. Fertility health promotion through education should be comprehensive and widely available in secondary schools, colleges, and universities. As well, increased education regarding fertility health in primary care settings should become the norm-with male inclusion as a standard of their care.

Comparison of sperm preparation methods to improve the recovery of mature spermatozoa in sub-fertile males

The integrity of chromatin in the spermatozoon is essential for reproductive outcome. The aim of this study was to evaluate the most effective and cost-effective method to reduce the percentage of spermatozoa with defects in chromatin decondensation for use in assisted reproductive technologies (ART) procedures. Sperm samples from 15 sub-fertile males were examined at CFA Naples to determine the sperm decondensation index (SDI), using the aniline blue test, before and after preparation, comparing density gradients with two different swim-up approaches. All three techniques led to a reduction in decondensed spermatozoa with no statistical difference (P > 0.05) between the control and the treated sperm. In contrast, we found a highly significant decrease in SDI (P < 0.01) after the two swim-up methods in all the samples, confirming the efficacy of these methods in lowering the percentage of chromatin compaction damage. There was no statistical difference between the two swim-up methods, however swim-up from the pellet led to improved count, motility and the percentage of normal condensed spermatozoa. We suggest that swim-up from the pellet be used in ART on sub-fertile males, both to reduce cell stress by multiple centrifugation and improve the recovery rate of mature spermatozoa.

Paramedical counselling in infertility treatment: its effects on anxio-depressive symptom severity, perceived stress and self-esteem

Aims

The importance of contributing psychological factors and stress-control in female infertility is well documented, but research on their role in male infertility is scarce. The present study aimed to evaluate the effects of a novel paramedical counselling on anxio-depressive symptom severity, perceived stress and self-esteem in infertile men participating in an infertility treatment programme.

Methods

Patients were recruited from clinics of University of Szeged, Hungary between 2019 May and 2020 December, and were sorted into control (n = 51) and experimental (n = 57) groups, where patients in the experimental group received a 5-session paramedical counselling in extension to their medical treatment. The levels of anxio-depressive symptom severity, perceived stress and self-esteem were measured prior to and after receiving paramedical counselling. The control group scored lower in regards of the severity of depressive symptom, and showed an increase of self-esteem, while the experimental group resulted in a significant decrease of anxio-depressive scores with the elevation of the level of self-esteem.

Results

Our results indicate that joining an infertility treatment programme alone had a positive role in reducing depressive symptoms and in the increase of self-esteem among infertile men, but receiving additional paramedical counselling throughout the treatment programme resulted in the decrease of anxio-depressive symptoms, besides the elevation of the level of self-esteem, with a significantly higher decrease in the state anxiety compared to not receiving this additional paramedical counselling.

Conclusions

Thus, it would be advisable for infertility treatment programmes to incorporate screening for psychological vulnerability and implement additional paramedical counselling to alleviate these confounding symptoms detrimental to conceiving.

Exploring male perceptions regarding the need to engage in preconception care - a mixed-method study amongst Dutch (prospective) fathers

PURPOSE

While most preconception care (PCC) interventions are aimed at women, men are also in need of PCC to reduce risk factors affecting the spermatozoa quality. The objective of this study is to explore male perceptions regarding the need to engage in PCC.

MATERIALS AND METHODS

In a mixed-method cross-sectional study, 229 men participated with a questionnaire and 14 individual semi-structured interviews were conducted. Questionnaires data were analysed using multiple regression analyses. The interviews were analysed using thematic analyses.

RESULTS

Most men did not retrieve preconceptional information (n = 135; 59.0%) nor visited a preconceptional consult (n = 182; 79.5%). Men who categorised their preconceptional lifestyle as unhealthy (score ≤6 out of 10) less often retrieved information (adjusted OR 0.36 [95% CI 0.14-0.93]) than men with a healthy preconceptional lifestyle. While several men expressed their fear for infertility, this did not lead to an increased uptake of PCC as men felt they were healthy enough already.

CONCLUSION

Despite high awareness of the positive influence of a healthy lifestyle, the perceived need for preparing for pregnancy among men remains low. Tailoring preconceptional information towards male needs provides a window of opportunity to improve men's reproductive health and possibly the health of future generations.

Reprotoxic Impact of Environment, Diet, and Behavior

Reproductive health is progressively declining due to multiples endogenous and exogenous factors, such as environmental contaminants, diet and behavior. Accumulated evidences confirm that fertility and reproductive function have been adversely affected by exposure to chemical contaminants released in the environment. Today, the impact of diet and behavior on reproductive processes is also receiving special attention from the scientific community. Indeed, a close relationship between diet and fertility has been proven. Furthermore, a combination of unhealthy behavior, such as exposure to hazardous compounds and stress factors, poses living organisms at higher risk of reprotoxic effects. In particular, it has been described that poor life behaviors are associated with reduced male and female fertility due to decreased gamete quality and function. Most of the erroneous behaviors are, furthermore, a source of oxidative stress that, leading to epigenetic alterations, results in an impaired reproductive fitness. This review reports the detrimental impact of the most common environmental chemical stressors, diet, and behavior on reproductive functionality and success. Although clear evidences are still scarce, reassuring data are provided that a healthy diet and reverting unhealthy lifestyles may be of help to recover physiological reproductive conditions.

Fertility knowledge and its related factors among married men and women in Zanjan, Iran

This study aimed to investigate the fertility knowledge and its related factors in married men and women in Zanjan, Iran. In this cross-sectional study, 1200 individuals (including 600 women aged 18-49 years and 600 men aged 18-59 years) referred to urban and rural health centres in Zanjan, were recruited through cluster sampling from June to September 2020. The Cardiff Fertility Knowledge Scale was used to assess fertility knowledge. Data were analysed by descriptive statistical methods such as mean and standard deviation and analytical statistics, including independent sample t-test, ANOVA test, Pearson Correlation and Linear Regression were used. The average correct scores of fertility knowledge were 49.7%, 53.3%, and 51.55% for men, women, and in total, respectively. The multiple linear regression model showed that fertility knowledge was significantly related to being female, being from a higher economic status, having desire to have children in the future, and having desire to increase fertility knowledge (all p < 0.05). Fertility knowledge among the Iranian reproductive-age men and women was modest. The findings suggested that interventions to increase fertility knowledge are essential, especially interventions targeting men and lower socioeconomic groups.

Risky Business: Increasing Fertility Knowledge of Men in the General Public Using the Mobile Health Application Infotility XY

Male infertility presents a public health concern. As most men wish to become fathers, it is important to increase men’s awareness of infertility risk factors. We developed a mobile health application (mHealth app), Infotility XY, to promote men’s reproductive health. This study evaluates whether use of the app led to increased knowledge of infertility risk factors, and whether knowledge change was associated with participants’ sociodemographic characteristics and/or app usage. Participants were recruited between August and October 2020. Eligibility criteria included: identified as male; 18–45 years old; childless; no infertility history; able to read and write in English/French; had internet access. We assessed participants’ fertility knowledge before and after app use. App usage data were captured during the 2-week intervention period. Our sample included 49 men aged 18–45. Seventy-eight percent of participants had not previously sought fertility information. Participants viewed on average 75% of the app’s articles, and 96% of participants said the app increased their fertility knowledge. Before app use, 55% of men said they were aware of infertility risk factors, compared to 96% after app use. Men correctly identified more risk factors after app use compared to before, t(48) = 8.28, p < .001. Participants’ sociodemographic characteristics and amount of app usage were not associated with knowledge change. This study provides evidence of the feasibility of an mHealth app to improve men’s awareness of infertility risk factors. Given the positive relationship between male reproductive health and overall health, increased awareness of infertility risk factors may lead to men’s improved overall health.

The factors affecting male infertility: A systematic review

Background

In recent years, the incidence of male infertility has increased worldwide. It is necessary to study the factors that influence male infertility in each area/region for better management.

Objective

To determine the factors affecting male infertility in the Iranian male population.

Materials and Methods

An online search was conducted in electronic databases including PubMed, Google Scholar, SID, and Scopus to identify articles on the factors associated with male infertility, published in English and Persian. The keywords used to perform the search included "factor", "epidemiology", "causes of infertility", and "male infertility". The search was conducted without a time restriction, up to April 2020.

Results

The search resulted in a total number of 691 studies. After an assessment of the articles, finally 14 studies were included in this study with a total number of 26,324 infertile males. The factors associated with male infertility included semen abnormalities, varicocele and testis disorder, smoking, exposure to heat, obesity, anabolic steroids, vascular abnormalities, anti-spermatogenesis factors, antidepressants, taking ranitidine and cimetidine, penile discharge and genital ulcers, painful micturition, occupational factors, alcohol, chronic disease, sexual disorder, Surgical and urological diseases, genetic factors and herpes infection. Among these, the semen and varicocele disorders were common in most studies.

Conclusion

The present review suggests that the factors affecting male infertility in Iran are similar to those reported from other countries. The results of this study can be used in adopting appropriate strategies for infertility management in Iran.

Barriers and factors associated with significant delays to initial consultation and treatment for infertile patients and partners of infertile patients

RESEARCH QUESTION

What are the key drivers and barriers for infertile patients and their partners to see an infertility specialist and initiate treatment?

DESIGN

An online, international, 30-minute quantitative survey collected data from 1944 respondents from nine countries. Respondents were infertile patients (n = 1037) or partners of infertile patients (n = 907; but not necessarily partners of the patient sample), at different stages of the treatment journey.

RESULTS

The overall average times were 3.2 years to receiving a medical infertility diagnosis, 2.0 years attempting to achieve pregnancy without assistance before treatment, and 1.6 years of treatment before successful respondents achieved pregnancy. The most common driver for considering treatment after a consultation (n = 1025) was an equal desire within the couple to have a child (40.8%). Of the partners (n = 356), 29.8% reported that transparency of information from healthcare professionals about treatment expectations was important. A significantly higher proportion of respondents seeking treatment reported that healthcare professionals offered supportive services (61.2%) and mental health services (62.0%), than of the 207 respondents who did not seek treatment (32.4% and 36.7%, respectively; P < 0.001). Perceived cost was the most commonly reported barrier for respondents not seeking a consultation (37.5% of n = 352) or treatment (42.0% of n = 207). Of the 95 respondents who discontinued treatment, 34.7% discontinued due to the financial impact.

CONCLUSIONS

Respondents reported significant delays to seeking treatment, probably negatively impacting the chances of achieving pregnancy. Motivational coherence within couples was a key driver and cost of treatment was the main barrier. Reported supportive service offerings by healthcare professionals were significantly associated with continuation of the treatment journey.

Knowledge and attitudes about assisted reproductive technology: Findings from a Hungarian online survey

This study aimed to evaluate the general knowledge and attitudes about assisted reproductive technology (ART) and the influence of sociodemographic features on knowledge and attitudes in a large sample of men and women of reproductive age in Hungary. A cross-sectional online survey study was conducted among 1370 men and women between 18 and 50 years of age in Hungary. The questionnaire included questions about self-rated knowledge, an attitude item, and eight questions concerning general knowledge about ART. In addition, participants were asked sociodemographic background questions. The results show that approximately half of the respondents (49.3%) rated themselves as fairly knowledgeable about ART. However, 56% of the respondents answered just three of the eight knowledge questions correctly. Both men and women had limited knowledge about the success rate of ART, the costs of ART and the age limit to access ART. The greatest lack of knowledge about ART was about its risks: the majority of respondents did not know that in-vitro fertilization poses health risks for women and conceived children. Regarding attitudes, the majority of respondents had a very positive attitude towards ART. Only those respondents who were religious were less supportive of ART. These data suggest that men and women of reproductive age overestimate their ART-related knowledge. As most men and women would like to have biological children in Hungary, there is a critical need for public education.

Men's perception and understanding of male-factor infertility in the UK

Male-factor infertility is a common but stigmatised issue, and men often do not receive the emotional support and the information they need. This study sought to understand awareness of male fertility issues compared to female fertility among the UK general male public, and also what were perceived as being the optimum methods for providing support for affected men, emotionally and through information. Men feel that male infertility is not discussed by the public as much as female infertility. Lifestyle issues that affect male fertility are not well understood, and men affected by infertility desire more support, including online, from health professionals and through peer support. Health professionals, including those in public health, could offer evidence-based programmes to reduce stigma and increase public knowledge about infertility, as well as offer emotional support to men with infertility problems.

The Association Between Male Infertility and Cardiometabolic Disturbances: A Population-Based Study

BACKGROUND

Further studies are needed to extend our knowledge about the association between male infertility and cardio-metabolic disorders.

OBJECTIVES

We aimed to assess the association between male infertility and cardiometabolic disturbances using a population-based design.

METHODS

In total, 1611 participants of the Tehran-Lipid and Glucose-Study (phase III) were categorized into two groups of men with documented male infertility (n = 88) and those with at least one live birth and no history of primary infertility (n = 1523). Logistic regression was applied to explore the association between male infertility and cardiometabolic disturbances, including diabetes mellitus, pre-diabetes, hypertension, metabolic syndrome, dyslipidemia, obesity, central obesity, and chronic kidney disease, following adjustment for age and body mass index (BMI).

RESULTS

The unadjusted model revealed a significant association between infertility and hypertension and CKD (OR = 1.8; 95% CI: 1.2, 2.9, P-value = 0.006 and OR = 1.9; 95% CI: 1.1, 3.6, P-value = 0.033), respectively. However, after adjusting for age and BMI, as potential confounders, this association was not significant. Moreover, there was no association between infertility and other cardiometabolic disturbances, including diabetes and pre-diabetes, metabolic syndrome, dyslipidemia, obesity, and central obesity in both unadjusted and adjusted models.

CONCLUSIONS

Our study revealed no association between male infertility and cardiometabolic disturbances. The findings can pave the way for further studies to extend our knowledge in this field. More population-based studies with a large sample size are warranted to confirm these findings.

Correlation between the DNA fragmentation index (DFI) and sperm morphology of infertile patients

Purpose

To evaluate the correlation between the DNA Fragmentation Index (DFI) and sperm morphology in patients undergoing ICSI, as a predictive parameter in reproductive outcomes.

Methods

A retrospective study was conducted on 125 infertile patients enrolled in a fertility clinic. Seminal characteristics were measured following the WHO guidelines (2010) for the examination of the seminal fluid. After collecting motile sperm population by pellet swim up, DFI was calculated and simultaneously associated with sperm morphology using in situ TUNEL assay and an image analyzer software in at least 250 spermatozoa for each patient.

Results

All subjects were divided into two groups according to a cutoff established, by choice, of the sperm DFI (15%): group A (< 15%) consisting of 65 patients and group B (≥ 15%) of 60 patients. Data were analyzed using non-parametric statistical methods. The results demonstrate that there is no statistical difference between the two groups in seminal characteristics. The collective data show a high significant correlation, suggesting that spermatozoa with abnormal morphology are the best candidates to contain DNA damage (p < 0.001). Also, when group A is compared with group B, an increased percentage of morphologically normal spermatozoa with fragmented DNA was observed in patients, with DFI values ≥ 15% (p < 0.001).

Conclusion

These results are aimed at providing an exact value of DFI in morphologically normal spermatozoa, which will be helpful to the embryologist in evaluating the risk of transferring, during the ICSI procedure, a spermatozoon whit normal morphology but fragmented DNA.

Fertility awareness and intentions among young adults in Greece

BACKGROUND

Greece has a mean age of first motherhood at 31.5 years, higher than the European average age of 29.4. Delaying conception, however, may be an important non-reversible cause of infertility. The aim of this study was to identify possible knowledge deficits regarding fertility in young adults.

METHODS

This was an online survey of young adults, regarding information on intention to parenthood and knowledge on issues affecting fertility. This study was conducted from February to December 2020, aiming for a representative sample of Greek men and women aged 18 and 26 years. The questionnaire was designed by a multidisciplinary group based on the Cardiff Fertility Knowledge Scale, which contained 22 multiple-choice or Likert-scale questions.

RESULTS

We obtained responses from 1875 young adults, whose mean age was 22.1 years. About 91.8% of men and 94.0% of women declared an intention to have children, out of which 44.0% wanted to have two and 29.0% three children. About 52.0 and 50.8% men and women, respectively, aimed to start a family between 31 and 35 years. Residents of rural areas and those with a lower education level more likely aimed to have children before the age of 30. The most prevalent answers for age of ideal parenthood were between 26 and 30 years for a woman and 31-35 years for a man. Smoking, alcohol consumption and sexually transmitted infections were identified as factors affecting both female and male fertility. Half of men and women, respectively, overestimated general success rates of reproductive techniques.

CONCLUSION

The knowledge of fertility, particularly with regards to assisted reproductive techniques' success rates, may be overestimated as more young adults plan for having children after the age of 30.

Gamete preservation: knowledge, concerns and intentions of Israeli and Danish students regarding egg and sperm freezing

RESEARCH QUESTION

What do Danish and Israeli students of both sexes know about age in relation to fertility and gamete preservation, and what are their concerns and intentions for the future in this regard?

DESIGN

A cross-sectional comparative study of male and female Danish and Israeli students was conducted between November 2018 and April 2019. A total of 1010 students, 508 from Denmark and 502 from Israel, completed questionnaires assessing knowledge, perceptions and intentions regarding gamete preservation.

RESULTS

More than 70% of both genders in Israel thought that women start experiencing fertility decline at age 35 and up. A total of 60% of Danish women and 51% of Danish men chose 29-34 as the time where fertility decline starts. Some 95% of Danish students chose 20-29 as the best age for egg freezing, while the corresponding number in Israel was 85%, regardless of gender. In total, 51% of Israeli women said they are extremely or very worried about future infertility, compared with 31% of Danish women, 26% of Israeli men and 12% of Danish men. Regarding preservation intentions, no gender differences were found. Some 3% of Israeli students said they would consider gamete preservation, as compared with 14% of Danish students.

CONCLUSIONS

These findings suggest a widespread worry among Danish and Israeli women about their future fertility. Danish students report more awareness of age-related fertility decline. Unique to this study is the inclusion of male students. The preliminary findings reveal that men are less worried about their reproductive future.

Is it an issue before it's a problem? Investigating men's talk about fertility

While fatherhood and male involvement in family life have been the focus of much research during the past few decades, we know less about men's involvement in the stage that precedes fatherhood and reproductive decision-making, their awareness of and sense of responsibility for reproductive health and fertility. This article draws attention to how men talk about fertility and reproductive intentions, focusing on how their perceptions and knowledge of fertility and procreation are structured around social norms and expectations. The study was based on interviews with 25 men in reproductive age with no prior history of infertility, including men with as well as without children and men of different sexual orientations and gender diversity. Our findings indicate a tension between, on the one hand, a general tendency among the men to take their fertility for granted and neither think nor talk about it, and, on the other hand, a latent concern about possible infertility which seemed to be activated in the interview situation. These findings raise questions of how conversations about fertility might impact men's thinking about their own fertility that call for further exploration and that are of significance in considerations of how to promote fertility awareness and reproductive health.

Online Japanese-Language Information on Lifestyle Factors Associated With Reduced Fertility: Content Analysis

Background

Approximately one-third of Japanese couples currently worry or previously worried about infertility. To develop strategies for the primary prevention of infertility as a population approach, it is important for the general population to be knowledgeable about fertility and infertility. The internet may contribute to the dissemination of information regarding infertility and fertility. However, few studies have examined online information about fertility.

Objective

This study aimed to quantitatively examine online Japanese-language information about lifestyle factors associated with reduced fertility.

Methods

We conducted online searches, using the 10 search terms with the highest numbers of searches that people hoping to conceive are likely to input in two major search engines in Japan (Google Japan and Yahoo! Japan). From the 2200 retrieved websites, 1181 duplicates and 500 websites unrelated to our objective were excluded, resulting in a final dataset of 519 websites. Coding guidelines were developed for the following lifestyle factors associated with reduced fertility: sexually transmitted diseases, psychological stress, cigarette smoking, alcohol use, nutrition and diet, physical activity and exercise, underweight, overweight and obesity, and environmental pollutants.

Results

In terms of the website author’s professional expertise, 69.6 % of the coding instances for the selected lifestyle factors were mentioned by hospitals, clinics, or the media, whereas only 1.7% were mentioned by laypersons. Psychological stress (20.1%) and sexually transmitted diseases (18.8%) were the most frequently mentioned lifestyle factors associated with reduced fertility. In contrast, cigarette smoking, alcohol use, nutrition and diet, physical activity and exercise, underweight, overweight and obesity, and environmental pollutants were mentioned relatively infrequently. The association between reduced fertility and sexually transmitted diseases was mentioned significantly more frequently by hospitals and clinics than by the media (P<.001). The association between reduced fertility and nutrition and diet was mentioned significantly more frequently by the media than by hospitals and clinics (P=.008). With regard to the sex of the target audience for the information, female-specific references to psychological stress, sexually transmitted diseases, nutrition and diet, underweight, physical activity and exercise, and overweight and obesity were significantly more frequent than were male-specific references to these lifestyle factors (psychological stress: P=.002, sexually transmitted diseases: P<.001, nutrition and diet: P<.001, underweight: P<.001, physical activity and exercise: P<.001, overweight and obesity: P<.001).

Conclusions

Of the lifestyle factors known to be related to reduced fertility, cigarette smoking, alcohol use, and male-specific lifestyle factors are mentioned relatively infrequently in online information sources in Japan, and these factors should be discussed more in information published on websites.

Knowledge gaps in the understanding of fertility among non-medical graduate students

Objective

To assess knowledge of female and male fertility among students enrolled in a Master of Business Administration (MBA) program.

Design

Web-based cross-sectional survey.

Setting

Academic setting.

Patient(s)

Not applicable.

Intervention(s)

None.

Main Outcome Measure(s)

Knowledge of how female and male age impacts reproduction, fecundability, and success rates with in vitro fertilization (IVF).

Result(s)

A total of 133 female and male MBA students completed the survey. Nearly 10% of participants were not aware that women are born with a fixed number of oocytes and that oocyte quantity and quality decline with age. More than 30% of participants overestimated fecundability in women aged ≥35 years, and >50% overestimated IVF success rates in women older than 40 years. Fifteen percent of participants did not know that men have stem cells in the testes, and >25% were not aware that men experience a decrease in sperm concentration and quality with age. Nearly 30% believed that a man’s age never impacts reproductive outcomes. Less than 30% of participants correctly estimated fecundability and IVF success rates based on male age.

Conclusion(s)

These data highlight important knowledge gaps in a highly educated group of MBA students, most whom desire future childbearing. Specifically, there is a lack of understanding of both male and female reproductive aging and an overestimation of treatment success. As delayed childbearing continues, particularly among those with high educational attainment, attention should be focused on introducing broad fertility education at a younger age to improve future reproductive success.

Taking fertility for granted - a qualitative exploration of fertility awareness among young, childless men in Denmark and Sweden

Most previous studies about fertility knowledge and attitudes among men have been based on quantitative methods using questionnaires with fixed-choice response options. The aims of this qualitative study were to explore childless young men's reflections on fertility and infertility through semi-structured interviews. Danish (n = 17) and Swedish (n = 12) young childless men aged between 20 and 30 years in their last year of education were interviewed. Data were analysed using qualitative content analysis. Few informants had considered their own fertility, and most were positive towards fertility treatment. The young men had inadequate knowledge about factors that can potentially impair male and female fertility. On average, the young men each mentioned three different factors they believed influence male and female fertility: (i) health behaviour; (ii) factors beyond personal control; and (iii) age. None mentioned sexual transmitted infections (STIs) but most appeared aware of the effect of increasing age on fertility. The results of this study highlight the need for educational strategies to improve young men's knowledge about fertility and the factors that influence it, particularly about the potential adverse effect of STIs on fertility.

Qualitative Research in Male Infertility

Qualitative research methods represent a valuable tool for investigating the entirety of the experience of male infertility evaluation, diagnosis, and treatment. Qualitative research is rigorous and thorough and well adapted for studying the complex field of infertility and reproductive health. Knowledge gained from qualitative research methods can undoubtedly inform clinical practice and improve support for individuals and couples affected by male factor infertility.

Vitamins combined with traditional Chinese medicine for male infertility: A systematic review and meta-analysis

BACKGROUND

Male infertility is a tough problem in medicine. This article aims to provide the latest evidence for the efficacy and safety of traditional Chinese medicine (TCM) combined with vitamins in the treatment of male infertility.

METHOD

All randomized controlled trials (RCTs) that used TCM combined with vitamins for male infertility treatment were included in databases of China National Knowledge Infrastructure (CNKI), Wanfang, VIP Database, China Biology Medicine disc (CBM), MEDLINE, EMBASE, and Cochrane Library. The quality of the included articles was evaluated using the Cochrane Reviewer's Handbook 5.3, and meta-analysis was performed using Stata 15.

RESULTS

A total of 14 eligible studies with 1488 patients were included in this meta-analysis. The results suggested that, compared with vitamin E or vitamin E + C alone, combination of TCM with vitamins increased significantly sperm concentration, sperm motility, sperm viability, liquefaction time of semen, the activity of acrosome enzyme, and the pregnancy rate of patients with male infertility. Three kinds of TCM (Shengjing capsule, Huanshao capsule, and compound Xuanju capsule) showed significant improvement for male infertility in terms of pregnancy rate, sperm concentration, or sperm motility. In addition, the results of the publication bias test demonstrated that no significant bias occurred.

CONCLUSION

Traditional Chinese medicine combined with vitamins has significant efficacy in the treatment of male infertility with no increase in side effects. The specific implementing regulations still need more long-term, multicenter, randomized, and double-blind clinical trials.

In everybody's interest but no one's assigned responsibility: midwives' thoughts and experiences of preventive work for men's sexual and reproductive health and rights within primary care

Background

Sexual and reproductive health and rights (SRHR) have historically been regarded as a woman’s issue. It is likely that these gender norms also hinder health care providers from perceiving boys and men as health care recipients, especially within the area of SRHR. The aim of this study was to explore midwives’ thoughts and experiences regarding preventive work for men’s sexual and reproductive health and rights in the primary care setting.

Methods

An exploratory qualitative study. Five focus group interviews, including 4–5 participants in each group, were conducted with 22 midwives aged 31–64, who worked with reproductive, perinatal and sexual health within primary care. Data were analysed by latent content analysis.

Results

One overall theme emerged, in everybody’s interest, but no one’s assigned responsibility, and three sub-themes: (i) organisational aspects create obstacles, (ii) mixed views on the midwife’s role and responsibility, and (iii) beliefs about men and women: same, but different.

Conclusions

Midwives believed that preventive work for men’s sexual and reproductive health and rights was in everybody’s interest, but no one’s assigned responsibility. To improve men’s access to sexual and reproductive health care, actions are needed from the state, the health care system and health care providers.

Prediction of in vitro fertilization outcome at different antral follicle count thresholds combined with female age, female cause of infertility, and ovarian response in a prospective cohort of 8269 women

Antral follicle count (AFC) has been widely investigated for the prediction of clinical pregnancy or live birth. This study discussed the effects of AFC quartile levels on pregnancy outcomes combined with female age, female cause of infertility, and ovarian response undergoing in vitro fertilization (IVF) treatment. At present, many research about AFC mainly discuss its impact on clinical practice at different thresholds, or the analyses of AFC with respect to assisted reproductive technology outcomes under using different ovarian stimulation protocols. Factors that include ovarian sensitivity index, female age, and infertility cause are all independent predictors of live birth undergoing IVF/intracytoplasmic sperm injection, while few researchers discussed influence of female-related factors for clinical outcomes in different AFC fields.A total of 8269 infertile women who were stimulated with a long protocol with normal menstrual cycles were enrolled in the study, and patients were categorized into 4 groups based on AFC quartiles (1-8, 9-12, 13-17, and ≥18 antral follicles).The clinical pregnancy rates increased in the 4 AFC groups (28.25% vs 35.38% vs 37.38% vs 40.13%), and there was a negative association between age and the 4 AFC groups. In addition, female cause of infertility like polycystic ovary syndrome, Tubal factor, and other causes had great significance on clinical outcome, and ovarian response in medium (9-16 oocytes retrieved) had the highest clinical pregnancy rate at AFC quartiles of 1 to 8, 9 to 12, 13 to 17, and ≥18 antral follicles.This study concludes that the female-related parameters (female cause of infertility, female age, and ovarian response) combined with AFC can be useful to estimate the probability of clinical pregnancy.

Tobacco smoking and semen quality in infertile males: a systematic review and meta-analysis

BACKGROUND

Nowadays, the total number of couples visiting an infertility clinic is on the rise. Tobacco smoking is considered one of the major factors leading to male infertility. In this study, we aimed to systematically investigate the impact of tobacco smoking on semen quality in infertile male participants.

METHODS

Online databases (Cochrane Central database of Randomized Controlled Trials and the databases of MEDLINE and EMBASE respectively) were searched for relevant English publications that satisfied the inclusion and exclusion criteria of this analysis. The clinical endpoints which were assessed included semen parameters (oligozoospermia, asthenozoospermia, teratozoospermia, and azoospermia), morphological defects of spermatozoa and the hormones involved in reproduction. RevMan 5.3 software was used to analyze the data whereby mean difference (MD) and risk ratios (RR) with 95% confidence intervals (CI) were generated to represent the results.

RESULTS

Sixteen studies with a total number of 10,823 infertile male participants (5257 smokers and 5566 non-smokers) were included. Results of this analysis showed oligozoospermia to be significantly higher in smokers (RR: 1.29, 95% CI: 1.05-1.59; P = 0.02). Morphological defect of spermatozoa (MD: 2.44, 95% CI: 0.99-3.89; P = 0.001) was also significantly higher in smokers whereby significant head (MD: 1.76, 95% CI: 0.32-3.20; P = 0.02), neck (MD: 1.97, 95% CI: 0.75-3.18; P = 0.002) and tail (MD: 1.29, 95% CI: 0.35-2.22; P = 0.007) defects were observed. However, smoking did not affected the pH (MD: 0.04, 95% CI: [- 0.03-0.11]; P = 0.30) and motility (RR: 1.42, 95% CI: 0.97-2.09; P = 0.07) of spermatozoa. Additionally, tobacco smoking did not cause any dis-balance in hormones which were involved in reproduction.

CONCLUSIONS

In conclusion, with reference to the clinical endpoints which were studied in this analysis, tobacco smoking was associated with a lower sperm count and an increase in the number of morphological defects of spermatozoa. However, the pH and motility of spermatozoa as well as the production of hormones which were involved in reproduction were not affected in this population of infertile males.

The duration of infertility affects semen parameters in primary infertile men: results of a single-centre, cross-sectional study

OBJECTIVE

To assess the relationship between the duration of infertility (DI) and the seminal parameters of a cohort of White-European primary infertile men.

PATIENTS AND METHODS

Data from 1644 infertile men were analysed. Patients were grouped according to the self-reported DI into 12-month time frames. Semen analysis values were assessed based on 2010 World Health Organisation reference criteria. Descriptive statistics tested the difference in clinical, hormonal and seminal parameters between groups. Logistic regression models assessed the impact of DI on semen parameters.

RESULTS

A DI of <12, 13-24, 25-36, 37-48, 49-60 and >60 months was found in 207 (12.6%), 651 (39.6%), 387 (23.5%), 168 (10.2%), 92 (5.6%) and 139 (8.4%) men, respectively. Patient's age (P < 0.001) and body mass index (P < 0.001) significantly increased along with DI. Hormonal values were similar across groups. Sperm concentration significantly decreased with DI (P = 0.01). Similarly, a higher rate of non-obstructive azoospermia (NOA) was more frequently found in men with a longer DI (P = 0.03). There were no differences in semen volume, sperm progressive motility, total motile sperm count (TMSC), and normal morphology across groups. Multivariable logistic regression analysis showed that DI was significantly associated with the risk of oligozoospermia (P < 0.001), TMSC <5 × 10⁶ (P < 0.001), and NOA (P < 0.001).

CONCLUSIONS

This cross-sectional study showed that DI had a negative impact on semen parameters in primary infertile men. Sperm concentration was negatively associated with DI and patients with a longer DI reported higher rates of azoospermia. Furthermore, DI was significantly associated with a higher risk of oligozoospermia, low TMSC, and NOA.

Can Reproductive Life Plan-based counselling increase men's fertility awareness?

BACKGROUND

Many men have limited knowledge about reproductive health and fertility. The aim of the study was to evaluate if Reproductive Life Plan (RLP)-based counselling during a sexual health visit could increase men's fertility awareness.

MATERIAL AND METHODS

The study was a randomized controlled trial including 201 men aged 18-50 who visited either of two participating sexual health clinics in Sweden for sexually transmitted infection testing during 2014-2016. All men received standard care, and men in the intervention group (IG) also received oral and written RLP-based information about lifestyle and fertility. Awareness about fertility and lifestyle-related factors were the main outcomes, measured through a questionnaire before the intervention and through a telephone survey after three months. Impressions from the counselling were also assessed at follow-up.

RESULTS

A majority (71%) of men wanted children in the future. General fertility awareness increased from a mean score of 4.6 to 5.5 out of 12 (P = 0.004) in the IG. The mean number of accurate lifestyle factors (that could affect fertility) mentioned increased from 3.6 to 4.4 (P < 0.001) in the IG. There were no improvements in the control group. Among the men in the IG, 76% had a positive experience of the counselling, and 77% had received new information.

CONCLUSION

The intervention managed to increase different aspects of men's fertility awareness. In the future, the format for preconception care for men needs further development. Including men in preconception health policy guidelines and identifying suitable actors for care provision would be important first steps.

Melatonin attenuates detrimental effects of diabetes on the niche of mouse spermatogonial stem cells by maintaining Leydig cells

Diabetes mellitus affects a large number of men of reproductive age and it usually leads to serious reproductive disorders. However, the underlying mechanisms and specific therapies still remain largely unknown. We observed Leydig cell loss in the testes of diabetic mice. Continuous high glycemic status of testes stimulated expression of Caspase12, Grp78, and Chop, the three ERS response factors; this might induce cell cycle arrest and apoptosis of Leydig cells in response to ERS. In these diabetic mouse models, melatonin alleviated apoptosis of testicular stromal cell induced by ERS, and promoted SSCs self-renewal by recovering Leydig cells secretion of CSF1 after 8 weeks of treatment. To explore the relationship between CSF-1 and ERS in Leydig cells, we treated Leydig tumor cell line with an activator Tuniamycin and an inhibitor 4-Phenylbutyrate of ERS. Our data showed that the CSF-1 expression in mouse Leydig cell lines decreased six-fold while reversely increasing five-fold in the 4-Phenylbutyrate-treated group. Thus, melatonin likely alleviates the loss of Leydig cells in diabetic testes and provides a healthier niche for SSCs to self-renew and continually provide healthy sperm for male fertility.

Attitudes towards family formation among men attending fertility counselling

Men and women are increasingly postponing childbearing until an age where fertility has decreased, meaning that they might have difficulties in achieving their desired family size. This study explored childless men's attitudes towards family formation. Data were collected through semi-structured qualitative interviews with 21 men attending the Fertility Assessment and Counselling Clinic in Copenhagen or Horsens, Denmark. Data were analysed using content analysis. The men envisioned a nuclear family with their own biological children, but they experienced doubts and ambivalence about parenthood and feeling 'ready'. Their lack of readiness was linked to their awareness of the sacrifices and costs involved with parenthood, and their belief that they could safely delay parenthood. The men did not consider that they may be unable to have their own biological children. This study highlights the importance of considering men's attitudes and preferences towards family formation when understanding couples' decision-making. Contrary to common understanding, the findings show that men are as concerned with the planning and timing of parenthood as women, but their knowledge of the age-related decline in fertility is poor. Men need to gain more awareness of the limitations of fertility and the impact of female and male age on the ability to achieve parenthood aspirations.

What do people know about fertility? A systematic review on fertility awareness and its associated factors

INTRODUCTION

Recent evidence indicates that reproductive-age people have inadequate fertility awareness (FA) concerning fertility, infertility risk factors, and consequences of delaying childbearing. However, no study has tried to summarize these studies and to clarify the variables associated with FA, namely the role of gender, age, education, and reproductive status on FA.

METHODS

A literature search up to February 2017 was conducted using the EBSCO, Web of Science, Scielo, and Scopus electronic databases with combinations of keywords and MeSH terms (e.g. 'awareness' OR 'health knowledge, attitudes, practice' AND 'fertility'; 'fertile period'; 'assisted reprod*').

RESULTS

Seventy-one articles met the eligibility criteria and were included. The main results showed that participants report low-to-moderate FA. Higher levels of FA were shown by women, highly educated individuals, people who reported difficulties with conceiving, and those who had planned their pregnancies. Having or desiring to have children was not related to FA level. An inconsistent association between study participant age and FA was observed, with some studies indicating that older participants had higher FA, but others found an opposite result or did not find any association.

CONCLUSION

The current findings suggest that interventions to increase FA are warranted, especially those targeting men, people with low education, and in family planning settings. Interventions and campaigns should be customized to meet individuals' needs regarding FA. Because of the high heterogeneity regarding the assessment of FA, these conclusions must be interpreted with caution.

Attitudes towards Social Oocyte Freezing from a Socio-cultural Perspective

INTRODUCTION

The tendency to delay parenthood is increasing. It is partly driven by the availability of early reproductive technologies such as social oocyte freezing, the cryopreservation of oocytes for non-medical purposes. The goal of this study was to investigate relationships between attitudes towards social oocyte freezing and different socio-cultural backgrounds in a German sample cohort.

MATERIALS AND METHODS

A quantitative online questionnaire was compiled. A total of 643 participants completed the questionnaire which included items on attitudes toward social oocyte freezing, socio-demographics and items, obtained from the German DELTA Institute for Social and Ecological Research, devised to indicate specific milieus. Data were analyzed using parametric and non-parametric methods.

RESULTS

There were clear correlations between attitudes towards social oocyte freezing and socio-cultural background, gender, cohort age, fertility problems, and attitudes to fertility. Positive attitudes towards social oocyte freezing were linked to struggles with fertility, a current or general wish to have a child, and flexible, progressive and self-oriented values. Participants who preferred to become parents at a younger age tended to reject cryopreservation.

CONCLUSIONS

The huge number of university graduates, persons with fertility problems, and persons from specific socio-cultural backgrounds in our sample point to distinct groups interested in reproductive technologies such as social oocyte freezing. The investigated differences as a function of socio-cultural background suggest that more research into the desire to have children in German society is needed. In conclusion, it may be necessary to develop targeted family planning interventions to prevent affected women from buying into a false sense of security, thereby risking unwanted childlessness.
