Abstract
Ovulation is critical for both conception and overall health, but many people who may ovulate are not tracking ovulation or any other part of their menstrual cycle. Failure to track ovulation, especially in those trying to conceive, can lead to fertility challenges due to absent ovulation, mistiming intercourse, or an undetected luteal phase defect. Ovulatory disorders and mistiming intercourse are both primary causes of infertility, and tracking ovulation is shown to decrease the average time to conception. While there are many tracking methods and apps available, the majority are predictive apps or ovulation predictor kits and do not test or track both successful ovulation and the health of the luteal phase, leading to missing information that could contribute to diagnosis or successful conception. Here, we review why ovulation tracking and a healthy luteal phase are important for those trying to conceive. We present currently available ovulation tracking methods that detect both ovulation and the luteal phase, including cervical mucus, urinary hormone testing, and basal body temperature, and discuss the use, advantages, and disadvantages of each. Finally, we consider the role of digital applications and tracking technologies in ovulation tracking.

Abstract
The purpose of the current study was to understand female rugby players' perceptions of menstrual cycle (MC) tracking and identify the impact of MC tracking for the players. Interpretive descriptive methodology was adopted. Interviews were conducted with 12 elite female rugby players (age 25.2 ± 4.3 years), who were all naturally menstruating. Data were analysed following the four stages recommended within Interpretive Description. Results identified that athletes obtain personal benefits from MC tracking by; enhancing understanding of their MC and symptoms, and responding to their MC and symptoms. Athletes also reported that the process of tracking their MC enhanced relationships by; improving communication and interactions with coaches and support staff, and by facilitating team support. Specifically, using tracking increased the opportunities for open conversations with coaches, support staff and teammates regarding their MC. Overall, the findings highlight benefits of menstrual cycle tracking within this group of naturally menstruating rugby players, particularly in helping players and coaches understand the individual nature of the MC, engage in conversations, and establish support from teammates.

Abstract
For generations, women have relied on fertility awareness methods to plan and prevent pregnancy, for over a decade, many have been aided by digital tools to do so. New contraceptive fertility tracking apps (CFTAs)-that are backed by clinical efficacy trials to support their effectiveness as contraception-have the potential to enhance method choice and offer users a unique contraceptive option, but there is little evidence to inform the decisions around expanding access, particularly in low-and middle-income countries. We conducted a mixed methods study with quantitative online surveys (n = 1600) and qualitative interviews (n = 36) to explore the potential appeal of and demand for a hypothetical CFTA in one such market, the Philippines. Interest in using a CFTA was high among our Internet-engaged, urban study population, with 83.9% "definitely" or "probably" interested in using it. Across demographic profiles, respondents perceived the appeal of the method as "natural" and "convenient." A majority were willing to pay for the method, though notably at a price (5.20 USD) below that of currently available CFTAs. We discuss various important factors to be considered before bringing a method like this to new markets, including the potential implications of equity constraints in reaching a wider market and the unexpected prevalence of other period-tracking apps not intended as contraception being used in this market that could complicate any future roll-out. These issues could be explored further with additional research.

Abstract
BACKGROUND Menstrual cycle tracking apps are increasingly used by those trying to conceive as well as those diagnosed and treated for infertility. However, the small amount of existing research about the use of these apps does not include the perspectives of healthcare providers. AIMS This study explores how healthcare providers describe the role of menstrual apps in fertility and infertility health care, and how this compares with patients' views. MATERIALS AND METHODS Responses were collected from an online survey (n = 37 providers and n = 89 patients) and online focus groups (n = 4 providers and n = 6 patients) and analysed using reflexive thematic analysis. RESULTS Healthcare providers, as well as some patients, expressed doubts about the accuracy of app estimates of the timing of ovulation. By contrast, many patients, but no healthcare providers, were enthusiastic about ovulation estimates provided by their apps. Apps were described by both groups as having a role in diagnosing and treating infertility, with healthcare providers emphasising the calendar history function of the apps supporting treatment, and patients focused on recognising and diagnosing infertility. CONCLUSIONS This exploratory study suggests that apps are viewed by both healthcare providers and patients as having a potential role in fertility and infertility healthcare. Although patients and app users are attentive to app estimates of ovulation timing, healthcare providers are sceptical.

Abstract
RESEARCH QUESTION What are the experiences of users of period tracking apps in relation to which apps they use, their frequency of use, the type of data and their attitudes to period tracking apps? DESIGN This was an observational mixed-methods study using an online survey designed using Qualtrics XM. The survey included 50 open-ended and multiple choice questions, but only specific questions were analysed in this study. The survey was promoted via social media for 22 days between 30 June and 21 July 2021. RESULTS Of the 375 total participants, 326 responses were complete and included in analysis. In the results section further down, this is explained as 330 complete responses, with 4 additional responses excluded due to data inconsistencies. The participants' age range was 14-54 years, with a mean of 26.0 (±7.81) years. Most participants (61.9%) had been using a period tracking app for 2 years or longer. Of these 85.6% entered more data when on their period, 31% at a frequency of once a day. There were approximately equivalent proportions of participants who felt that entering data into their app was either 'part of their normal routine' (43.3%) or 'not a priority' (38.0%). Thematic analysis of the participants' experiences of using period-tracking apps revealed five main themes: symptom tracking and understanding general health; concerns with period start date predictions; the problems with fertility tracking; concerns about cost; and concerns about data privacy. CONCLUSIONS The infrequency of data inputting and the wide range of symptoms tracked reflects the differing needs of participants from their period-tracking apps. This highlights the need for increased education and research into understanding the realities of variations in using apps.

Abstract
BACKGROUND Emerging digital health technology has moved into the reproductive health market for female individuals. In the past, mobile health apps have been used to monitor the menstrual cycle using manual entry. New technological trends involve the use of wearable devices to track fertility by assessing physiological changes such as temperature, heart rate, and respiratory rate. OBJECTIVE The primary aims of this study are to review the types of wearables that have been developed and evaluated for menstrual cycle tracking and to examine whether they may detect changes in the menstrual cycle in female individuals. Another aim is to review whether these devices are effective for tracking various stages in the menstrual cycle including ovulation and menstruation. Finally, the secondary aim is to assess whether the studies have validated their findings by reporting accuracy and sensitivity. METHODS A review of PubMed or MEDLINE was undertaken to evaluate wearable devices for their effectiveness in predicting fertility and differentiating between the different stages of the menstrual cycle. RESULTS Fertility cycle-tracking wearables include devices that can be worn on the wrists, on the fingers, intravaginally, and inside the ear. Wearable devices hold promise for predicting different stages of the menstrual cycle including the fertile window and may be used by female individuals as part of their reproductive health. Most devices had high accuracy for detecting fertility and were able to differentiate between the luteal phase (early and late), fertile window, and menstruation by assessing changes in heart rate, heart rate variability, temperature, and respiratory rate. CONCLUSIONS More research is needed to evaluate consumer perspectives on reproductive technology for monitoring fertility, and ethical issues around the privacy of digital data need to be addressed. Additionally, there is also a need for more studies to validate and confirm this research, given its scarcity, especially in relation to changes in respiratory rate as a proxy for reproductive cycle staging.

Abstract
Objective: Despite growing concerns that some digital algorithm-reliant fertility awareness-based methods of pregnancy prevention are marketed in an inaccurate, opaque, and potentially harmful manner online, there has been limited systematic examination of such marketing practices. This article therefore provides an empirical examination of how social media influencers have promoted the fertility tracking tool Daysy on Instagram. We investigate: (1) how the tool is framed in relation to pregnancy prevention using Health Belief Model (HBM) constructs, and (2) the promotional and disclosure practices adopted by influencers. Materials and Methods: We collected Instagram posts mentioning Daysy made between June 2018 and May 2022 using the tool CrowdTangle. Using a qualitative content analysis approach, we coded a random sample of 400 Daysy posts. This yielded 122 Instagram influencer posts promoting Daysy for pregnancy prevention that we coded for promotional content and HBM constructs. Results: Posts originated primarily from Europe (n = 62, 50.82%) and the United States (n = 37, 30.33%). Findings indicate that barriers to use (n = 18, 15.57%) and the severity of risks from unplanned pregnancy (n = 8, 6.56%) were rarely conveyed, whereas benefits of use (n = 122, 100%) and the severity of risks of hormonal contraception (n = 31, 25.41%) were covered more extensively. Only about one third of posts disclosed any formal relationship to the brand Daysy. Conclusions: With many posts emphasizing benefits and obscuring potential limitations, we argue that accurate and transparent information about the effectiveness and limitations of fertility tracking technologies is critical for supporting informed decision-making and, as such, should remain a public health priority.

Abstract
Purpose of review a)The modifiable and non-modifiable determinants and the currently available methods of assessment of menstrual blood flow will be discussed, with the goal of helping healthcare providers, researchers, and those interested in public health. Recent findings b)Several factors can impact menstruation. The determinants include modifiable factors such as smoking, nutrition, exercise, stress, weight fluctuation, and benign gynecologic diseases, and non-modifiable factors such as age, race, and the individual's genes. The intertwined dynamic among these determinants needs more critical attention. Currently, the methods for the assessment of menstruation all have advantages and disadvantages, often with a tradeoff between practicality and accuracy. Summary c)Considered by many as the fifth vital, menstruation provides a window to an individual's general health. The discussion of its determinants and assessment can be more appropriate for individual contexts, especially from a public health perspective as it can improve the reproductive health of the population.

Abstract
BACKGROUND Many factors influence fertility, one being the timing of intercourse. The 'fertile window' describes a stage in the cycle when conception can occur and is approximately five days before to several hours after ovulation. 'Timed intercourse' is the practice of prospectively identifying ovulation and, thus, the fertile window to increase the likelihood of conception. Methods of predicting ovulation include urinary hormone measurement (luteinising hormone (LH) and oestrogen), fertility awareness-based methods (FABM) (including tracking basal body temperatures, cervical mucus monitoring, calendar charting/tracking apps), and ultrasonography. However, there are potentially negative aspects associated with ovulation prediction, including stress, time consumption, and cost implications of purchasing ovulation kits and app subscriptions. This review considered the evidence from randomised controlled trials (RCTs) evaluating the use of timed intercourse (using ovulation prediction) on pregnancy outcomes. OBJECTIVES To evaluate the benefits and risks of ovulation prediction methods for timing intercourse on conception in couples trying to conceive. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility (CGF) Group Specialised Register, CENTRAL, MEDLINE, and Embase in January 2023. We also checked the reference lists of relevant studies and searched trial registries for any additional trials. SELECTION CRITERIA We included RCTs that compared methods of timed intercourse using ovulation prediction to other forms of ovulation prediction or intercourse without ovulation prediction in couples trying to conceive. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane to select and analyse studies in this review. The primary review outcomes were live birth and adverse events (such as depression and stress). Secondary outcomes were clinical pregnancy, pregnancy (clinical or positive urinary pregnancy test not yet confirmed by ultrasound), time to pregnancy, and quality of life. We assessed the overall quality of the evidence for the main comparisons using GRADE methods. MAIN RESULTS This review update included seven RCTs involving 2464 women or couples. Four of the five studies from the previous review were included in this update, and three new studies were added. We assessed the quality of the evidence as moderate to very low, the main limitations being imprecision, indirectness, and risk of bias. Urinary ovulation tests versus intercourse without ovulation prediction Compared to intercourse without ovulation prediction, urinary ovulation detection probably increases the chance of live birth in couples trying to conceive (risk ratio (RR) 1.36, 95% confidence interval (CI) 1.02 to 1.81, 1 RCT, n = 844, moderate-quality evidence). This suggests that if the chance of a live birth without urine ovulation prediction is 16%, the chance of a live birth with urine ovulation prediction is 16% to 28%. However, we are uncertain whether timed intercourse using urinary ovulation detection resulted in a difference in stress (mean difference (MD) 1.98, 95% CI -0.87 to 4.83, I² = 0%, P = 0.17, 1 RCT, n = 77, very low-quality evidence) or clinical pregnancy (RR 1.09, 95% CI 0.51 to 2.31, I² = 0%, 1 RCT, n = 148, low-quality evidence). Similar to the live birth result, timed intercourse using urinary ovulation detection probably increases the chances of clinical pregnancy or positive urine pregnancy test (RR 1.28, 95% CI 1.09 to 1.50, I² = 0, 4 RCTs, n = 2202, moderate-quality evidence). This suggests that if the chance of a clinical pregnancy or positive urine pregnancy test without ovulation prediction is assumed to be 18%, the chance following timed intercourse with urinary ovulation detection would be 20% to 28%. Evidence was insufficient to determine the effect of urine ovulation tests on time to pregnancy or quality of life. Fertility awareness-based methods (FABM) versus intercourse without ovulation prediction Due to insufficient evidence, we are uncertain whether timed intercourse using FABM resulted in a difference in live birth rate compared to intercourse without ovulation prediction (RR 0.95, 95% CI 0.76 to 1.20, I² = 0%, 2 RCTs, n = 157, low-quality evidence). We are also uncertain whether FABM affects stress (MD -1.10, 95% CI -3.88 to 1.68, 1 RCT, n = 183, very low-quality evidence). Similarly, we are uncertain of the effect of timed intercourse using FABM on anxiety (MD 0.5, 95% CI -0.52 to 1.52, P = 0.33, 1 RCT, n = 183, very low-quality evidence); depression (MD 0.4, 95% CI -0.28 to 1.08, P = 0.25, 1 RCT, n = 183, very low-quality evidence); or erectile dysfunction (MD 1.2, 95% CI -0.38 to 2.78, P = 0.14, 1 RCT, n = 183, very low-quality evidence). Evidence was insufficient to detect a benefit of timed intercourse using FABM on clinical pregnancy (RR 1.13, 95% CI 0.31 to 4.07, 1 RCT, n = 17, very low-quality evidence) or clinical or positive pregnancy test rates (RR 1.08, 95% CI 0.89 to 1.30, 3 RCTs, n = 262, very low-quality evidence). Finally, we are uncertain whether timed intercourse using FABM affects the time to pregnancy (hazard ratio 0.86, 95% CI 0.53 to 1.38, 1 RCT, n = 140, low-quality evidence) or quality of life. No studies assessed the use of timed intercourse with pelvic ultrasonography. AUTHORS' CONCLUSIONS The new evidence presented in this review update shows that timed intercourse using urine ovulation tests probably improves live birth and pregnancy rates (clinical or positive urine pregnancy tests but not yet confirmed by ultrasound) in women under 40, trying to conceive for less than 12 months, compared to intercourse without ovulation prediction. However, there are insufficient data to determine the effects of urine ovulation tests on adverse events, clinical pregnancy, time to pregnancy, and quality of life. Similarly, due to limited data, we are uncertain of the effect of FABM on pregnancy outcomes, adverse effects, and quality of life. Further research is therefore required to fully understand the safety and effectiveness of timed intercourse for couples trying to conceive. This research should include studies reporting clinically relevant outcomes such as live birth and adverse effects in fertile and infertile couples and utilise various methods to determine ovulation. Only with a comprehensive understanding of the risks and benefits of timed intercourse can recommendations be made for all couples trying to conceive.

Abstract
OBJECTIVE To assess the effect of randomization to FertilityFriend.com, a mobile computing fertility-tracking app, on fecundability. DESIGN Parallel non-blinded randomized controlled trial nested within the Pregnancy Study Online (PRESTO), a North American preconception cohort. PATIENT(S) Female participants aged 21 to 45 years attempting conception for ≤6 menstrual cycles at enrolment (2013-2019). INTERVENTION Randomization (1:1) of 5532 participants to receive a premium Fertility Friend (FF) subscription. MAIN OUTCOME MEASURE(S) Fecundability (per-cycle probability of conception). Participants completed bimonthly follow-up questionnaires until pregnancy or a censoring event, whichever came first. We first performed an intent-to-treat analysis of the effect of FF randomization on fecundability. In secondary analyses, we used a per-protocol approach that accounted for adherence in each trial arm. In both analyses, we used proportional probabilities regression models to estimate fecundability ratios (FR) and 95% confidence intervals (CI) comparing those randomized vs. not randomized and applied inverse probability weights to account for loss-to-follow-up (intent-to-treat and per-protocol analyses) and adherence (per-protocol analyses only). RESULTS Using life-table methods, 64% of the 2775 participants randomized to FF and 63% of the 2767 participants not randomized to FF conceived during 12 cycles; these respective percentages were each 70% among those with 0-1 cycles of attempt time at enrolment. Of those randomized to FF, 72% were defined as adherent (68% of observed menstrual cycles). In intent-to-treat analyses, there was no appreciable association overall (FR = 0.97; 95% CI, 0.90-1.04) or within strata of pregnancy attempt time at enrolment, age, education, or other characteristics. In per-protocol analyses, we observed little association overall (FR = 1.06; 95% CI, 0.99-1.14), but weak-to-moderate positive associations among participants who had longer attempt times at enrolment (FR = 1.15; 95% CI, 0.98-1.35 for 3-4 cycles; FR = 1.14; 95% CI, 0.87-1.48 for 5-6 cycles), were aged <25 years (FR = 1.29; 95% CI, 1.01-1.66), had ≤12 years of education (FR = 1.32; 95% CI, 0.92-1.89), or were non-users of hormonal contraception within 3 months before enrolment (FR = 1.10; 95% CI, 1.02-1.19). CONCLUSION No appreciable associations were observed in intent-to-treat analyses. In secondary per-protocol analyses that accounted for adherence, randomization to FF was associated with slightly greater fecundability among selected subgroups of participants; however, these results are susceptible to unmeasured confounding.

Grace B, Shawe J, Stephenson J. A mixed methods study investigating sources of fertility and reproductive health information in the UK. SEXUAL & REPRODUCTIVE HEALTHCARE 2023; 36:100826. [PMID: 36842189 DOI: 10.1016/j.srhc.2023.100826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 02/06/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023]
Abstract
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.

Abstract
Objectives Menstruation tracking digital applications (MTA) are a popular technology, yet there is a lacuna of research on how women use this technology for the management of PMS. Theoretical frameworks for understanding users' experiences are also underdeveloped in this nascent field. The objectives of the study were therefore twofold, to propose a theoretical framework for understanding women's use of MTA and apply it to the analysis of users' experiences in the management of PMS. Method A novel theoretical framework was proposed, informed by post-phenomenology, postfeminist healthism, feminist new materialism and digital health technologies as public pedagogy. This framework focuses analytic attention on affective relationships between subjectivity, bodily sensations, digital technology, and discourse. It was used to structure the analysis of five in-depth timeline interviews with women in Aotearoa New Zealand who experienced benefits from using MTA to manage PMS symptoms. Results Three pedagogical relationships were identified: a pedagogy of empowerment, where users learnt to control, predict and manage their PMS symptoms in line with healthism; a pedagogy of appreciation, where users learnt to understand their menstruating bodies as amazing, a valued part of them, and awe-inspiring that radically overturned past internalised stigma; and an 'untrustworthy teacher' who eroded this affirmative learning through inaccuracy, positioning users in dis-preferred categories, or being 'creepy'. Conclusions MTA offers huge possibilities for challenging menstrual stigma that need to be nurtured, developed, and protected; and there are benefits for analysing MTA within wider scholarship on postfeminist healthism.

Broad A, Biswakarma R, Harper JC. A survey of women’s experiences of using period tracker applications: Attitudes, ovulation prediction and how the accuracy of the app in predicting period start dates affects their feelings and behaviours. WOMEN'S HEALTH 2022; 18:17455057221095246. [PMID: 35465788 PMCID: PMC9047811 DOI: 10.1177/17455057221095246] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/15/2022]
Abstract
Introduction: Using an online survey, the aim of this study was to ask women about their
real-life experiences of using period tracker apps, their attitudes towards
using their app, the information the app provided regarding ovulation and
how the accuracy of the app in predicting period start dates affects their
feelings and behaviours if their period comes earlier or later than
predicted. Methods: This mixed-methods observational study was conducted by an online survey of
50 multiple-choice and open-ended questions. The survey was generated with
Qualtrics XM® and promoted via social media. It was open to any
person who had used a period tracker. Results: From 375 total responses, 330 complete responses were obtained, giving a
completion rate of 88.0%. Respondents were aged between 14 and 54, with a
mean age of 26.0 (±7.81). When asked what was the best thing about using the
app, 29.7% (98/330) of respondents selected ‘To know when I’m ovulating’.
Respondents were asked if their period ever started earlier than the app
predicted; 54.9% (189/330) said it had and 72.1% (238/330) said it had
started later than predicted. When asked how they felt if their period
arrived earlier or later than expected, thematic analysis of periods
starting earlier revealed four themes: feeling unaffected, being
frustrated/unprepared, feeling anxious/stressed and feeling
confused/intrigued. Thematic analysis when their period arrived later
revealed six themes: anxious/concerned about pregnancy, disappointed about
pregnancy, seeking advice/informing healthcare professionals, thoughts about
menopause, feeling unaffected and being better prepared. Conclusion: Period trackers need to be clearer on their intended use and reliability,
especially for period due date and ovulation. Qualitative analysis shows the
impact of inaccurate predictions on aspects of the users’ health. This study
calls for period tracker app companies to update their apps to provide
transparency to their users about their intended use and capabilities.
