Fertility rates in the UK are at an all-time low, with infertility affecting approximately 1 in 7 couples. Despite the rising demand for fertility services, fertility awareness, specifically knowledge of ovulation and the fertile window, remains low among women of reproductive age. Most existing studies offer a broad perspective, lacking focus on women actively trying to conceive (TTC). This study aims to assess the level of understanding surrounding the fertile window among women TTC, identifying factors associated with knowledge gaps.
Methods
A retrospective, cross-sectional analysis of 97,414 women actively TTC who answered an online health assessment was conducted. Participants provided information on menstrual cycle characteristics, previous pregnancies, and fertility knowledge, including the timing of the fertile window. Frequencies, percentages were calculated and chi-squared tests performed to assess differences in categorical data. Logistic regression models were used to calculate odds ratios (ORs) to better understand factors significantly associated with not knowing the fertile window.
Results
Out of the total respondents (97,414), over a third (33,756, 41%) could not accurately identify the fertile window, with substantial misconceptions observed across all age groups and ethnicities. Women with previous pregnancies were more likely to correctly identify the fertile window (OR = 1.45, 97.5% CI: 1.20-1.75, p < 0.001). However, knowledge was significantly lower among those with irregular cycles, non-White ethnicities, younger age groups and longer time TTC. Additionally, misconceptions about cycle regularity were apparent, of 60,322 women describing their cycles as regular 10% did not know their cycle length (66,95) and a further 2.9% fell outside of the clinically regular 21-35 day range. These misconceptions followed a similar trend with younger age groups, non-white ethnicities and longer time TTC having significantly increased rates of misidentifying regular cycles. This further increased the odds of not knowing their fertile window (OR = 2.99, 97.5% CI: 2.83-3.17, p < 0.001).
Conclusions
The findings reveal gaps in fertility awareness among women actively TTC. Addressing these knowledge gaps through targeted educational interventions could potentially reduce time-to-pregnancy and the reliance on assisted reproductive technologies. Improved fertility education focusing on cycle tracking and ovulation timing is essential to assist women with accurate information during their TTC journey.

Fertility treatment pathways are complex and lengthy. The current prevalence of infertility makes it a public health issue. The involvement of general practitioners and the training of fertility instructors to provide therapeutic education have been suggested as ways of involving patients in the process and improving the therapeutic trajectory of these patients, who often have co-morbidities. To describe the activity of trained fertility instructors; to assess the interest of doctors in the fertility chart provided by women; and to describe the outcomes of their fertility care pathway. 66 French fertility instructors were interviewed in June 2024. The 15 general practitioners who had received additional training were also interviewed. The records of all couples who received fertility counselling and treatment between 1 January 2022 and 31 December 2023, the study cut-off date, were analysed. Doctors declared that the women had gained a clear understanding of their menstrual cycle, which was useful for diagnosis and treatment follow-up. The chart was particularly useful for diagnosing the causes of infertility and identifying when in the cycle to take medication. Only 4 of the 551 women were lost to follow-up. Of the remaining 547 women, 204 (37%) became pregnant. Of these, 75% had a live birth or an ongoing pregnancy at study cut-off. The involvement of fertility instructors and general practitioners improved the couple s ability to interact with doctors and to adhere to infertility treatment. The fertility chart provided by the women proved to be useful in the diagnosis and treatment process.
The role of minerals in female fertility, particularly in relation to the menstrual cycle, presents a complex area of study that underscores the interplay between nutrition and reproductive health. This narrative review aims to elucidate the impacts of minerals on key aspects of the reproductive system: hormonal regulation, ovarian function and ovulation, endometrial health, and oxidative stress. Despite the attention given to specific micronutrients in relation to reproductive disorders, there is a noticeable absence of a comprehensive review focusing on the impact of minerals throughout the menstrual cycle on female fertility. This narrative review aims to address this gap by examining the influence of minerals on reproductive health. Each mineral's contribution is explored in detail to provide a clearer picture of its importance in supporting female fertility. This comprehensive analysis not only enhances our knowledge of reproductive health but also offers clinicians valuable insights into potential therapeutic strategies and the recommended intake of minerals to promote female reproductive well-being, considering the menstrual cycle. This review stands as the first to offer such a detailed examination of minerals in the context of the menstrual cycle, aiming to elevate the understanding of their critical role in female fertility and reproductive health.

Natural Procreative Technology (NaProTechnology) is a system of management of infertility and other reproductive health issues which requires the application of a woman’s observation and record of key events throughout her menstrual cycle. The study assessed the knowledge, awareness, and perception of NaProTechnology as well as the effect of an educational intervention among pharmacy undergraduate students at University of Nigeria, Nsukka. It was a cross-sectional, questionnaire-based study. The ethical approval was obtained from the research ethics committee of the Faculty of Pharmaceutical Sciences, University of Nigeria, Nsukka. At baseline, the knowledge, awareness and perception of the students were assessed. Followed by the administration of an educational video on NaProTechnology. Then a post intervention survey was done to assess the effect of the educational intervention. Key finding: s
There were 410 and 350 students in the preand post-intervention surveys respectively with relatively equal number of males and females. Majority were between 18 and 29 years old. Less than 5% were married while the highest proportion of the respondents were from 300 level The knowledge, awareness, and positive perception of NaProTechnology among the pharmacy students prior to intervention were poor but improved markedly post intervention (P < 0.001).
A video intervention was effective in improving the short-term knowledge, awareness and positive perception of NaProTechnology among pharmacy students. Key message: s
What is already known on this topic?
Natural Procreative Technology (NaProTechnology) is a system of management of infertility based on the observation and record of fertility biomarkers by a woman. What this study add: s?
The level of knowledge, awareness, and positive perception of NaProTechnology among the pharmacy undergraduates students were poor prior to a video intervention but improved markedly afterwards
How this study might affect research, practice or policy?
This study would lead to the public health system approach of informing, educating and communicating NaProTechnology to pharmacy students to achieve long-term effects by using well-designed courses and curriculum implementation.
