Global, regional and national burden of male infertility in 204 countries and territories between 1990 and 2019: an analysis of global burden of disease study

BACKGROUND

Many countries and regions have experienced male fertility problems due to various influencing factors, especially in less developed countries. Unlike female infertility, male infertility receives insufficient attention. Understanding the changing patterns of male infertility in the world, different regions and different countries is crucial for assessing the global male fertility and reproductive health.

METHODS

We obtained data on prevalence, years of life lived with disability (YLD), age-standardized rates of prevalence (ASPR) and age-standardized YLD rate (ASYR) from the Global Burden of Disease Study 2019. We analyzed the burden of male infertility at all levels, including global, regional, national, age stratification and Socio-demographic Index (SDI).

RESULTS

In 2019, the global prevalence of male infertility was estimated to be 56,530.4 thousand (95% UI: 31,861.5-90,211.7), reflecting a substantial 76.9% increase since 1990. Furthermore, the global ASPR stood at 1,402.98 (95% UI: 792.24-2,242.45) per 100,000 population in 2019, representing a 19% increase compared to 1990. The regions with the highest ASPR and ASYR for male infertility in 2019 were Western Sub-Saharan Africa, Eastern Europe, and East Asia. Notably, the prevalence and YLD related to male infertility peaked in the 30-34 year age group worldwide. Additionally, the burden of male infertility in the High-middle SDI and Middle SDI regions exceeded the global average in terms of both ASPR and ASYR.

CONCLUSION

The global burden of male infertility has exhibited a steady increase from 1990 to 2019, as evidenced by the rising trends in ASPR and ASYR, particularly in the High-middle and Middle SDI regions. Notably, the burden of male infertility in these regions far exceeds the global average. Additionally, since 2010, there has been a notable upward trend in the burden of male infertility in Low and Middle-low SDI regions. Given these findings, it is imperative to prioritize efforts aimed at improving male fertility and reproductive health.

Examining willingness to donate frozen oocytes among women of reproductive age

RESEARCH QUESTION

What are the predictors of willingness to donate frozen oocytes among women of reproductive age in Australia?

DESIGN

An online survey involving 303 women of reproductive age (18-49 years) in Australia who had not frozen their oocytes or planned to freeze their oocytes in the next 12 months. The survey assessed demographic variables, prototype willingness model variables (attitude, subjective norm, prototype similarity and prototype favourability) and additional variables (altruism, empathy and infertility awareness) as predictors of hypothetical scenarios of willingness to donate frozen oocytes. A multivariate repeated measures analysis of variance explored differences in willingness to donate frozen oocytes. Hierarchical multiple regression analysis examined predictors of donor willingness.

RESULTS

Women's willingness to donate their frozen oocytes was higher for donating to a friend or family member and to research compared with an egg bank or fertility clinic, or a couple advertising online for an egg donor (all P < 0.001). The prototype willingness model variables were significant predictors of willingness to donate showing slightly varied patterns across four scenarios. After accounting for demographics, regression models including prototype willingness model variables and additional variables accounted for 45-64% of variance in donor willingness.

CONCLUSIONS

Frozen oocyte donation may be facilitated by improving attitudes towards donation and establishing positive images of donors. Professionals requiring frozen oocytes for research could focus on creating a sense of social approval for donating in this context. Encouraging frozen oocyte donation could increase access to oocytes for IVF treatment and aid in reducing the psychological burdens associated with involuntary childlessness.

Main topics in assisted reproductive market: A scoping review

BACKGROUND

Infertility affects around 12% of couples, and this proportion has been gradually increasing. In this context, the global assisted reproductive technologies (ART) market shows significant expansion, hovering around USD 26 billion in 2019 and is expected to reach USD 45 billion by 2025.

OBJECTIVES

We realized a scoping review of the ART market from academic publications, market reports, and specialized media news, to identify the main terms and characterize them into the main topics in the area.

DESIGN

We apply an LDA topic modeling process to identify the main terms, and clustered them into semantic synonymous topics. We extracted the patterns and information to these topics and purposed a factor/consequence correlation to them.

RESULTS

We found 2,232 academic papers and selected 632 to include in the automatic term detection. We also included 34 market reports and seven notices produced by specialized enterprises. Were identified 121 most relevant cited terms covering 7,806 citations. These terms were manually aggregated into 10 topics based on semantic similarity: neutral terms (37.2%), economic aspects (17.6%), in vitro fertilization (IVF) commodities & cross-border reproductive care (CBRC) (10.6%), geographic distribution (9.5%), social aspects (7%), regulation (6%), trends & concerns (3.9%), accessibility (3.4%), internet influence (2.9%), and fertility preservation for non-medical reasons (2%).

DISCUSSION

The analysis indicates a market with expressive complexity. Most terms were associated with more than one topic, indicating the synergism of this market's behavior. Only seven terms related to economic aspects, surrogacy and donation represent around 50% of the citations. Except for the topic formed by generic terms, the topic of the economic aspects was the most represented, reflecting macro perspectives such as a-la-carte standard of treatments, many clinics operating on a small/medium scale, and the recent formation of conglomerates. The IVF commodities & CBRC topic brings an overview of gametes pricing and transnational surrogacy, and its regulation. The topic of geographic distribution indicates that that the Asia-Pacific (APAC) market has the most significant growth potential in all fields. Despite the increase in supply and demand for infertility treatments and technological advances in recent decades, the success rate of IVF cycles remains at around 30%. Terms referring to research and development or technical improvement were not identified in a significant way in this review.

CONCLUSIONS

The formation of topics by semantic similarity proved to be an initial path for the elaboration of in-depth studies on the dynamics between several factors, for this, we present the panel classifying main terms into factors (demand, pent-up demand, or distributive) or ART market consequences. Through this approach, it was possible to observe that most of the works addresses economic aspects, regulation and geographic aspects and that topics related to research and improvement have not been addressed. In this way, we highlight the need to deepen the analysis of market elements that may be related to increased efficiency of IVF in the technical field.

Information and decision support needs: A survey of women interested in receiving planned oocyte cryopreservation information

PURPOSE

Identifying the information and decision support needs of women interested in receiving planned oocyte cryopreservation (POC) information.

METHODS

An online survey of Australian women, aged 18-45, interested in receiving POC information, proficient in English, with internet access. The survey covered POC information sources, information delivery preferences, POC and age-related infertility knowledge (study-specific scale), Decisional Conflict Scale (DCS), and time spent considering POC. Target sample size (n=120) was determined using a precision-based method.

RESULTS

Of 332 participants, 249 (75%) had considered POC, whilst 83 (25%) had not. Over half (54%) had searched for POC information. Fertility clinic websites were predominately used (70%). Most (73%) believed women should receive POC information between ages 19-30 years. Preferred information providers were fertility specialists (85%) and primary care physicians (81%). Other methods rated most useful to deliver POC information were online. Mean knowledge score was 8.9/14 (SD:2.3). For participants who had considered POC, mean DCS score was 57.1/100 (SD:27.2) and 78% had high decisional conflict (score >37.5). In regression, lower DCS scores were associated with every 1-point increase in knowledge score (-2.4; 95% CI [-3.9, -0.8]), consulting an IVF specialist (-17.5; [-28.0, -7.1]), and making a POC decision (-18.4; [-27.5, -9.3]). Median time to decision was 24-months (IQR: 12.0-36.0) (n=53).

CONCLUSION

Women interested in receiving POC information had knowledge gaps, and wanted to be informed about the option by age 30 years from healthcare professionals and online resources. Most women who considered using POC had high decisional conflict indicating a need for decision support.

The development and phase 1 evaluation of a Decision Aid for elective egg freezing

BACKGROUND

Elective egg freezing decisions are complex. We developed a Decision Aid for elective egg freezing and conducted a phase 1 study to evaluate its acceptability and utility for decision-making.

METHODS

The online Decision Aid was developed according to International Patient Decision Aid Standards and evaluated using a pre/post survey design. Twenty-six Australian women aged 18-45 years, interested in receiving elective egg freezing information, proficient in English, and with access to the internet were recruited using social media and university newsletters. Main outcomes were: acceptability of the Decision Aid; feedback on the Decision Aid design and content; concern raised by the Decision Aid, and; utility of the Decision Aid as measured by scores on the Decisional Conflict Scale and on a study-specific scale assessing knowledge about egg freezing and age-related infertility.

RESULTS

Most participants found the Decision Aid acceptable (23/25), balanced (21/26), useful for explaining their options (23/26), and for reaching a decision (18/26). Almost all reported satisfaction with the Decision Aid (25/26) and the level of guidance  it provided (25/26). No participant reported serious concerns about the Decision Aid, and most would recommend it to other women considering elective egg freezing (22/26). Median Decisional Conflict Scale score decreased from 65/100 (Interquartile range: 45-80) pre-Decision Aid to 7.5/100 (Interquartile range: 0-37.5) post-Decision Aid review (p < 0.001). Median knowledge score increased from 8.5/14 (Interquartile range: 7-11) pre-Decision Aid to 11/14 (Interquartile range: 10-12) post-Decision Aid review (p = 0.01).

CONCLUSION

This elective egg freezing Decision Aid appears acceptable and useful for decision-making. It improved knowledge, reduced decisional conflict and did not raise serious concerns. The Decision Aid will be further evaluated using a prospective randomised control trial.

Awareness and attitude toward oocyte cryopreservation for non-medical reasons: a study on women candidates for social egg freezing

PURPOSE

The present study was to investigate awareness and attitudes toward female fertility and aging, desire for a child and motherhood, and oocyte freezing for non-medical reasons among women candidates for Social Egg Freezing (SEF).

MATERIALS AND METHODS

This was a cross-sectional study on all 216 women who sought oocyte cryopreservation for nonmedical reasons at Royan Institute. A 24-item self-administered questionnaire measured knowledge and attitudes to SEF. Responses were as yes/no or a 4-point Likert scale.

RESULTS

Only 40% of participants accurately indicated that having a sexual partner does not help to preserve their fertility. A quarter of women correctly recalled chance of pregnancy with unprotected intercourse during a period of a year, for women 20 to 40 years old. Only one-third of respondents accurately identified the age-related fertility decline at 35-39 years. Only 6.9% correctly mentioned the low chance of pregnancy after egg freezing at 35 years old. Almost a third of women knew that the age range of 31-35 years is the right age to freeze an egg with the highest chance of pregnancy. Aging and health of offspring were most influential in women's decisions on SEF.

CONCLUSION

In conclusion, there was significant gaps in knowledge about age-related fertility decline, and egg cryopreservation conditions and its complications. It is crucial to impart to these women a better knowledge about fertility and a realistic picture about SEF, especially on the number of high-quality retrieved mature oocytes and live birth rates depend on women's age.
