Despite sizable number of women suffering from infertility, empirical evidence on the relation between infertility and KOC is rare in South Asia. This study assesses the association between primary infertility and KOC. The data of ever-married women aged 20-49 gathered in the recent rounds of Demographic and Health Survey (DHS) for India (2019-2021), Bangladesh (2017-2018), Pakistan (2017-2018) and Nepal (2022) were analyzed. Bivariate analysis and binary logistic regression were conducted through Stata (V.17) with a 5% significance level. Women with no KOC in India [AOR:1.71, C.I.: (1.54, 1.9)] and Bangladesh [AOR:2.6, C.I.: (1.67, 4.06)] had higher odds of primary infertility than their counterparts with correct KOC. The study concludes that correct KOC is a significant predictor of primary infertility in India and Bangladesh and is insignificant in Pakistan and Nepal. Moreover, higher age at marriage and no-visit to healthcare facility were the other significant predictors of primary infertility in all four countries. Women who are struggling to conceive would benefit from education related to the timing and identification of the fertile window, which may be provided through primary healthcare providers.</p>","PeriodicalId":13006,"journal":{"name":"Human Fertility","volume":"28 1","pages":"2441832"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142863741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the recognition of the importance of increasing fertility awareness, levels remain low. This study evaluated the perceptions of 'FActs!', a serious game aimed at improving adolescents' fertility awareness. The narratives of adolescents, parents and teachers about the utility of this tool and its educational potential were also addressed using focus groups. The game (https://myfacts.eu/) comprises 12 questions (birth year, biological sex, country and nine questions addressing fertility topics (probability of conceiving, the definition of infertility, and fertility risk factors such as age, smoking, alcohol, drugs and physical exercise). These questions emerge from four scenarios: a school playground, a party, a gym and a sibling's house. Players receive immediate feedback about their answers and brief educational information to improve their knowledge. Players accumulate stars for correct answers as they progress through the scenarios and answer the questions. Findings revealed that 'FActs!' effectively engages adolescents and enhances their understanding of fertility. Adolescents, parents and teachers responded positively, appreciating its interactive nature and ability to facilitate discussions on reproductive health. However, limitations such as the need for more comprehensive information and high reading requirements were noted. The study highlights the importance of integrating comprehensive fertility education into health curricula using diverse, engaging methods. It also underscores the necessity of supporting parents and teachers to improve their comfort and capability in discussing fertility. \"FActs!\" is a valuable tool with the potential for broader educational contexts.

The number of women becoming pregnant via oocyte donation has increased markedly in recent years. Such pregnancies are accompanied by different risks to those of naturally conceived pregnancies. Anecdotal evidence suggests that women seeking oocyte donation pregnancy gain limited appreciation of the risks attending oocyte donation during consent discussions. To explore women's understanding of the risks associated with oocyte donation pregnancy a qualitative interview study was conducted in an ante-natal facility in an urban hospital. Sixteen women who had experienced oocyte donation pregnancy participated in semi-structured, audio-recorded interviews exploring their experience of the consent process for oocyte donation and their awareness of pregnancy-related risks once pregnant. Data were analysed using thematic analysis. Our principal finding was that women were unaware that their oocyte donation pregnancy carried higher risks than a typical IVF pregnancy. Three themes emerged: (1) women tended to care most about risks associated with success/failure of oocyte donation; (2) women did not know that oocyte donation pregnancies carry specific risks above and beyond IVF pregnancies; (3) women were ambivalent towards receiving risk information. For women accepting an oocyte donation consent at the time of undergoing IVF should include discussion of the risks of subsequent pregnancy to ensure that women are fully informed.

Respondents primarily relied on multiple sources for information about these add-ons, with search engines being the most frequently used, followed by fertility clinic websites, the HFEA website, and medical or scientific articles. These sources were also deemed the most reliable. In contrast, social media, online forums, and blogs were less frequently used and rated as less reliable. Respondents reported significant variation in the total cost per cycle of privately funded treatment, ranging from £5,000 to £13,000, with an average of £11,950. Although there was a slight upward trend in costs with rising household income, no strong correlation was observed. Fertility clinic websites were the primary source of cost-related information, with 99% of respondents emphasising the importance of clinics providing accurate and up-to-date information on their websites.
