Abstract
PURPOSE OF THE ARTICLE The main aim of the study was to analyze the population of women who used etonogestrel implant, the reason that led them to this type of contraception, and the degree of compliance with it. Materials and methods: We carried out a retrospective study on women who had etonogestrel subcutaneous implant placed (n°47) over a 6-year period (2015-2021). We submitted the women a series of questions by telephone questionnaire (range 10-72 months after placements, mean 40 months) that investigated the comorbidities and side effects related to etonogestrel implant. MATERIALS AND METHODS We carried out a retrospective study on women who had etonogestrel subcutaneous implant placed (n°47) over a 6-year period (2015-2021). We submitted the women a series of questions by telephone questionnaire (range 10-72 months after placements, mean 40 months) that investigated the comorbidities and side effects related to etonogestrel implant. RESULTS The average age of placement of etonogestrel implant was 33.8 ± 3.45 years. As regards level of education, 16/47 (34%) of the women had a university degree, 21/47 (44%) had a high school diploma and 10/47 (21%) had a secondary school diploma. The 12/47 (25%) of the women were, at the time of the counselling, unemployed and only 8% did not use in the past contraceptive methods other than etonogestrel implant. The 92% of women choose etonogestrel implant because it offered safe, comfortable and long-lasting contraception. Among the main side effects evaluated, we reported spotting in 24 out of 47 (51%), headache in 4 out of 47 (8.5%). The 85% of the women recommended etonogestrel implant to their friends as a contraceptive method, with an approval rating for the implant, expressed a rating from 1 to 10 with the mean that was 7.79, the median 8. CONCLUSIONS Our results are of interest because they derive from a region of Italy in which the Long acting reversible contraception (LARC) is strongly underused. Etonogestrel implant was a safe and effective, long-acting, reversible hormonal contraception (LARC) and majority of women recommended the etonogestrel implant to their friends as a contraceptive method.

Abstract
OBJECTIVES To describe unmet desire for long-acting reversible contraception (LARC) after the Zika Contraception Access Network (Z-CAN) in Puerto Rico during the 2016-2017 Zika outbreak. STUDY DESIGN Z-CAN patients completed surveys about contraception experiences over a 3-year period. RESULTS Of 1809 respondents, 3% never used LARC but reported wanting it since their initial visit. As reasons for not getting LARC, nearly 50% indicated a provider-related reason and 25% reported cost. CONCLUSIONS Few Z-CAN patients who never used LARC had unmet desire. Provider training in contraception guidelines and strategies to address costs can expand access to the full range of reversible contraception. IMPLICATIONS Three years after a short-term program provided reversible contraception in Puerto Rico, few respondents had never used but wanted a long-acting reversible contraception method. Nearly half reported provider-related reasons for not receiving long-acting reversible contraception, and 25% reported cost. Provider awareness of contraceptive guidance and method availability can support client-centered care.

Abstract
OBJECTIVE To evaluate gene expression associated with vaginal bleeding in the 52-mg hormonal intrauterine device (IUD) users. MATERIALS AND METHODS We conducted a prospective study involving 100 women seeking to use the 52-mg hormonal IUD for contraception. We excluded women with a history or current condition of abnormal uterine bleeding and who were unable to attend a 1-year follow up. Women who expelled the device, removed it for reasons unrelated to vaginal bleeding, or were lost to follow up were discontinued. We collected endometrial biopsies immediately before IUD placement and assessed 20 selected genes using reverse transcription quantitative polymerase chain reaction. Users maintained a uterine bleeding diary for 12 months following IUD insertion. For statistical analysis, participants were categorized into groups with or without vaginal bleeding at 3 and 12 months. RESULTS Women with elevated CXCL9 expression had an 8.15-fold higher likelihood of experiencing vaginal bleeding at 3 months (odds ratio [OR] 8.15, 95% confidence interval [CI] 2.24-29.61, P = 0.001). At 12 months of follow up, women with increased TIMP1 expression had a 2.74-fold higher chance of experiencing vaginal bleeding (OR 2.74, 95% CI 1.08-6.95, P = 0.033). CXCL9 ≥ 1.5 and IL17A ≥ 0.68 were associated with a higher probability of vaginal bleeding at 3 months, while TIMP1 levels ≥0.943 were linked to an increased risk of bleeding at 12 months. CONCLUSION Users of the 52-mg hormonal IUD with elevated relative CXCL9 expression face an increased risk of vaginal bleeding at 3-month follow up, whereas those with heightened TIMP1 expression are more likely to experience vaginal bleeding at 12 months.

Abstract
OBJECTIVE Use of 52-mg levonorgestrel intrauterine system (LNG-IUS) in adolescents for heavy menstrual bleeding (HMB), dysmenorrhea, and contraception has increased, yet little is known about the factors predicting removal and dissatisfaction in adolescents. The aim of this study was to identify factors predicting LNG-IUS removal in adolescents. METHODS This was a retrospective cohort study including all adolescents (9-19 years) who underwent LNG-IUS insertion between 2012 and 2021 (n = 536). A medical record review was conducted and data were collated on medical and gynecological history, age, indications for insertion, complications, expulsions, and removals. The data were analyzed using χ2 tests. RESULTS Indications for LNG-IUS insertions (n = 536) among 517 individual patients (n = 517) included menstrual management (n = 142), HMB alone (n = 118), HMB and pelvic pain/dysmenorrhea (n = 105), dysmenorrhea/pelvic pain alone (n = 47), and contraception (n = 16). Associated diagnoses included intellectual disability (44.29%, 229/517), chronic pain conditions (12.77%, 66/517), and additional mental health concerns (24.37%, 126/517). Patient dissatisfaction with LNG-IUS led to removal in 61 (11.38%), mostly for pain or persistent bleeding. Higher removal rates occurred in those with associated chronic pain conditions (46.97%, χ2 = 55.9, P < .05), mental health concerns (16.67%, χ2 = 5.06, P < .05), and bleeding disorders (26.32%, χ2 = 5.09, P < .05). Among the cohort with an intellectual disability, lower rates of removal occurred (5.7%, χ2 = 11.2, P < .05). Whereas the LNG-IUS removal rate among gender-diverse youth was 23.07%, this was not statistically significant. Younger age was also not associated with a statistically significant increase in removals (13.72%, χ2 = 0.73, P > .05). DISCUSSION Adolescents have a low dissatisfaction and removal rate (11.38%) of LNG-IUS. Chronic pain, bleeding tendency, and mental health concerns are associated with higher removal rates and intellectual disability with lower rates. These findings are useful in counselling patients and families about LNG-IUS.

Abstract
BACKGROUND Long-acting reversible contraceptives, including hormonal levonorgestrel-releasing intrauterine systems, are the most effective methods of reversible contraception. However, unfavorable bleeding, particularly during the first months of use, is one of the most important reasons for discontinuation or avoidance. Minimizing this as early as possible would be highly beneficial. Nonsteroidal anti-inflammatory drugs inhibiting prostaglandin synthesis are known to reduce bleeding and pain at time of menses. A levonorgestrel-releasing intrauterine system has been developed with an additional reservoir containing indomethacin, designed to be released during the initial postplacement period. OBJECTIVE This proof-of-concept study aimed to establish whether the addition of indomethacin to the currently available levonorgestrel-releasing intrauterine system (average in vivo levonorgestrel release rate of 8 μg/24 h during the first year of use) reduces the number of bleeding and spotting days during the first 90 days of use compared with the unmodified system. The dose-finding analysis included 3 doses of indomethacin-low (6.5 mg), middle (12.5 mg), and high (15.4 mg)-to determine the ideal dose of indomethacin to reduce bleeding and spotting days with minimal side-effects. STUDY DESIGN This was a multicenter, single-blinded, randomized, controlled phase II trial conducted between June 2018 and June 2019 at 6 centers in Europe. Three indomethacin dose-ranging treatment groups (low-, middle-, and high-dose indomethacin/levonorgestrel-releasing intrauterine system) were compared with the unmodified levonorgestrel-releasing intrauterine system group, with participants randomized in a 1:1:1:1 ratio. The primary outcome was the number of uterine bleeding and spotting days over a 90-day reference (treatment) period. Secondary outcomes were the number of women showing endometrial histology expected for intrauterine levonorgestrel application and the frequency of treatment-emergent adverse events. Point estimates and 2-sided 90% credible intervals were calculated for mean and median differences between treatment groups and the levonorgestrel-releasing intrauterine system without indomethacin. Point and interval estimates were determined using a Bayesian analysis. RESULTS A total of 174 healthy, premenopausal women, aged 18 to 45 years, were randomized, with 160 women eligible for the per-protocol analysis set. Fewer bleeding and spotting days were observed in the 90-day reference period for the 3 indomethacin/levonorgestrel-releasing intrauterine system dose groups than for the levonorgestrel-releasing intrauterine system without indomethacin group. The largest reduction in bleeding and spotting days was achieved with low-dose indomethacin/levonorgestrel-releasing intrauterine system, which demonstrated a point estimate difference of -32% (90% credible interval, -45% to -19%) compared with levonorgestrel-releasing intrauterine system without indomethacin. Differences for high- and middle-dose indomethacin/levonorgestrel-releasing intrauterine system groups relative to levonorgestrel-releasing intrauterine system without indomethacin were -19% and -16%, respectively. Overall, 97 women (58.1%) experienced a treatment-emergent adverse event considered related to the study drug, with similar incidence across all treatment groups including the unmodified levonorgestrel-releasing intrauterine system. These were all mild or moderate in intensity, with 6 leading to discontinuation. Endometrial biopsy findings were consistent with effects expected for the levonorgestrel-releasing intrauterine system. CONCLUSION All 3 doses of indomethacin substantially reduced the number of bleeding and spotting days in the first 90 days after placement of the levonorgestrel-releasing intrauterine system, thus providing proof of concept. Adding indomethacin to the levonorgestrel-releasing intrauterine system can reduce the number of bleeding and spotting days in the initial 90 days postplacement, without affecting the safety profile, and potentially improving patient acceptability and satisfaction.

Abstract
PURPOSE To investigate bleeding profile satisfaction and pain and ease of placement with levonorgestrel 19.5 mg IUD in routine clinical practice. METHODS Women who independently chose levonorgestrel 19.5 mg IUD during routine counselling were invited to participate in this prospective, multinational, observational study. Patient-reported pain and clinician-reported ease of placement were assessed. Bleeding profile satisfaction was evaluated at 12 months/premature end of observation. RESULTS Most participants (77.8%, n = 878/1129) rated levonorgestrel 19.5 mg IUD placement pain as 'none' or 'mild' and most clinicians (91.1%, n = 1029/1129) rated placement as 'easy'. Pain was more often rated higher in nulliparous compared with parous (p < .0001) and younger (<26 years) compared with older participants (p < .0001), although 67.7% and 69.0% of nulliparous and younger participants respectively reported 'none' or 'mild' pain. Bleeding profile satisfaction at 12 months/end of observation was similar in parous (72.9%, n = 318/436) and nulliparous (69.6%, n = 314/451) participants. Most participants irrespective of age reported bleeding profile satisfaction, ranging from 67.8% (n = 206/304) for 18-25 years to 76.5% (n = 218/285) for >35 years. CONCLUSION We observed high bleeding profile satisfaction regardless of age or parity with levonorgestrel 19.5 mg IUD and confirmed that device placement is easy and associated with no more than mild pain in most cases in routine clinical practice. Real-world evidence from the Kyleena® Satisfaction Study in routine clinical practice shows high bleeding profile satisfaction with levonorgestrel 19.5 mg IUD regardless of age or parity. IUD placement was easy and associated with little to no pain for most women.

Abstract
BACKGROUND Post-placement menstrual bleeding pattern changes with intrauterine contraceptives (IUCs), including levonorgestrel-releasing intrauterine systems (LNG-IUS), can be a reason for avoidance or early discontinuation. Prostaglandins play an important role in menstrual bleeding and pain. The key drivers of prostaglandin synthesis are cyclooxygenase (COX) enzymes, which are inhibited by non-steroidal anti-inflammatory drugs. In this study, we report the findings from pharmacokinetic (PK) analyses undertaken with an LNG-IUS (LNG-IUS 8) modified with an additional reservoir containing indomethacin (IND). METHODS The IND/LNG-IUS 8 is a proof-of-concept device studied in a phase II proof-of-concept/dose-finding study. IND/LNG-IUS 8 contains the same LNG content as the unmodified LNG-IUS 8 (13.5 mg) but was prepared with three different IND doses (low, 6.5 mg; middle, 12.5 mg; and high, 15.4 mg), resulting in different daily release rates. Overall, 174 healthy, premenopausal women were randomized to one of the four treatment arms (low-, middle-, high-dose IND/LNG-IUS 8 or LNG-IUS 8). Initial and residual IND and LNG content were collected and the amount of IND and LNG released in vivo over the period of use was calculated. A subset of 62 participants underwent dense blood sampling for PK analysis. Concentrations of IND and LNG in plasma were determined by validated liquid chromatography-tandem mass spectrometry methods and plotted over time. Descriptive statistics were calculated for plasma drug concentrations and PK parameters. RESULTS High-dose IND/LNG-IUS 8 initially released much higher levels of IND than expected based on in vitro release data, followed by a steep decline, with the reservoir emptied by 4.5 months. Middle- and low-dose IND/LNG-IUS 8 demonstrated steady sustained release of IND over time, emptying after 7.4 and 8.4 months, respectively. Peak plasma concentrations of IND for low- and middle-dose IND/LNG-IUS 8 remained below the 20% maximal inhibitory concentration (IC20) values for COX enzymes. The average daily IND release rate in vivo was 49 µg/day for low-dose and 112 µg/day for middle-dose IND/LNG-IUS 8. The IND release rate profile and IND plasma concentrations in vitro both decreased steadily over time with low- and middle-dose IND/LNG-IUS 8. The LNG release rate profile was comparable for all IND/LNG-IUS 8 dose groups and LNG-IUS 8. CONCLUSION This PK study demonstrates that two different drugs can be released at different rates from an IUS designed with two drug reservoirs. Inclusion of IND does not impact the LNG PK profile. Low- and middle-dose IND/LNG-IUS 8 were associated with a systemic IND exposure that should preclude the occurrence of adverse events typically observed after oral IND dosing.

Abstract
OBJECTIVE The aim of this study was to evaluate the satisfaction and menstrual bleeding pattern with levonorgestrel-releasing intrauterine systems (LNG-IUD) in young women. METHODS A prospective, multicentre, non-interventional study with 1-year follow-up was conducted in Spain. Participants were women between 18 and 30 years old who freely choose any available LNG-IUD for contraception. Satisfaction with LNG-IUD was measured with a 5-point Likert scale. Type of LNG-IUD, menstrual bleeding pattern and satisfaction with it, easiness of insertion and pain during procedure were collected. RESULTS A total of 555 women (37.3% parous, 62.7% nulliparous) (mean age 25.8 ± 3.5) completed the study. After 12 months, 92.4% of women were satisfied or very satisfied with the LNG-IUD, with no differences by parity status, type of IUD or baseline menstrual bleeding pattern. Satisfaction with the LNG-IUD correlated with satisfaction with menstrual bleeding pattern at 12 months. Up to 88.7% of women were satisfied or very satisfied with their menstrual bleeding pattern at 12 months in comparison to 41.5% at baseline (p < 0.001). Adverse events (AE)-related discontinuation rate was low (2.2%). CONCLUSIONS Satisfaction with LNG-IUD is very high among young Spanish women, regardless of parity and menstrual bleeding pattern at baseline.

Abstract
Family planning enables society to prevent unintended pregnancies and helps in attaining desired spacing between the pregnancies. It is done with the use of contraceptive methods and infertility treatments. The use of contraceptives serves to ease maternal ill-health and reduce pregnancy-related deaths and helps to decrease the number of unsafe abortions and HIV transmission from mothers to newborns. The most popular contraception method is a daily dose of combined oral contraceptives pills. However, poor compliance and various adverse effects are common problems of oral contraceptives that considerably reduce their long-term use. Thus, several non-oral contraceptive options have been developed for better compliance, reduced side effects and improved therapeutic efficacy. This review presented the non-oral contraceptive formulations given by different routes such as transdermal, nasal, subcutaneous, intramuscular, intrauterine and vaginal routes. These formulations delivering contraceptives, mainly through devices, include transdermal patches and microneedles, nasal sprays, intrauterine devices and intrauterine systems, vaginal rings, contraceptive implants and contraceptive injections, which are unique in their specific advantages and drawbacks.

[PMID: 35313863 PMCID: PMC8939098 DOI: 10.1186/s12905-022-01657-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Accepted: 03/03/2022] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE Levonorgestrel-releasing intrauterine devices (LNG-IUDs) and copper intrauterine devices (Cu-IUDs) offer long-acting contraception; however, some women may discontinue use within the first year due to bleeding pattern changes, limiting their potential. This systematic literature review investigated whether differences in bleeding profiles influence continuation rates in women in America, Europe and Australia. METHODS Searches performed in PubMed and Embase were screened to identify publications describing bleeding patterns and rates of early IUC removal/discontinuation or continuation, descriptions of bleeding patterns, reasons for discontinuation, and patient satisfaction, acceptability and tolerability for LNG-IUDs and Cu-IUDs published between January 2010 and December 2019. The results were further restricted to capture citations related to 'Humans' and 'Females'. The review was limited to studies published from 2010 onwards, as changing attitudes over time mean that results of studies performed before this date may not be generalizable to current practice. RESULTS Forty-eight publications describing 41 studies performed principally in the USA (n = 17) and Europe (n = 13) were identified. Publications describing bleeding patterns in LNG-IUD users (n = 11) consistently observed a reduction in bleeding in most women, whereas two of three studies in Cu-IUD users reported heavy bleeding in approximately 40% of patients. Rates of discontinuation for both devices ranged widely and may be as high as 50% but were lower for LNG-IUDs versus Cu-IUDs. Discontinuation rates due to bleeding were consistently higher for Cu-IUDs versus LNG-IUDs. CONCLUSIONS Bleeding is a common reason for discontinuation of Cu-IUDs and LNG-IUDs. The more favourable bleeding pattern observed in LNG-IUD users may be associated with a lower rate of early discontinuation of LNG-IUDs versus Cu-IUDs.

Abstract
OBJECTIVES Removal or discontinuation of long-acting reversible contraception (LARC) requires cooperation of healthcare providers. The objective of this study was to explore young women's experiences when they request removal of LARC within 12 months of insertion. METHODS We conducted a qualitative study using individual semi-structured telephone interviews with women living in Victoria, Australia. We recruited participants using physical and online advertising flyers. We audio-recorded and transcribed interviews and thematically analysed the data. RESULTS Fifteen women participated in an interview. The experience of unacceptable side effects prompted "early" LARC removal in all cases. The non-autonomous nature of LARC removal was not considered by women pre-insertion and participants reported confidence in their ability to access LARC removal when requested. Although satisfaction was reported when LARC was removed on request, participants reported negative feelings towards their healthcare provider when there was perceived pressure to continue with LARC for longer than desired. This had implications for the patient-clinician relationship. Women experienced resistance to removal as a challenge to their bodily autonomy and this resulted in a loss of trust in health services. CONCLUSION Resistance to removal of LARC can damage the patient-clinician relationship and be experienced as a challenge to women's autonomy and reproductive rights. IMPLICATIONS Patients have confidence in their ability to get their LARC removed on request and autonomy is not largely considered prior to LARC initiation. Supportive removal services should be emphasised for women who request removal of LARC at any point after insertion in order to maintain trust in healthcare providers and health services.

Abstract
STUDY OBJECTIVE Temporizing measures such as hormonal pills can temporarily improve the side effect of breakthrough bleeding in individuals using the etonogestrel implant. The aims of this study were to determine demographic factors that are associated with bothersome bleeding and to evaluate the impact of prescribing temporizing measures on implant continuation. DESIGN Retrospective chart review. SETTING The research was conducted in an adolescent medicine primary and specialty care clinic, an adolescent family planning clinic, and a clinic that cares for parenting adolescents. PARTICIPANTS A chart review was conducted on 1200 patients aged 12-24 years who received the implant in 2016. INTERVENTIONS AND MAIN OUTCOME MEASURES The primary outcome measure was removal of the implant within the first year of use. We followed each patient for 1 year to determine rates of removal, reasons for removal, and temporizing measures prescribed for bleeding. RESULTS Younger age and lower body mass index were associated with reporting bothersome vaginal bleeding. Patients who were nulliparous or had bothersome bleeding were more likely to have the implant removed in the first year. Patients who received a temporizing measure for bleeding were more likely to retain the implant for 1 year than were those who did not receive one (67.1% vs 40%, P < .001). CONCLUSIONS Some patients are more likely to report concerns with bleeding or to have the implant removed in the first year after insertion. Prescribing temporizing measures to control bothersome vaginal bleeding may decrease rates of removal in the first year.

Abstract
PURPOSE The Kyleena® Satisfaction Study (KYSS) aimed to assess satisfaction and continuation with levonorgestrel-releasing intrauterine system (LNG-IUS) 12 (Kyleena®) in routine clinical practice and to evaluate factors that influence satisfaction. MATERIALS AND METHODS This prospective, observational, multicentre, single-arm cohort study, with 1-year follow-up, was conducted in Belgium, Canada, Germany, Mexico, Norway, Sweden, Spain and the United States from 2017 to 2018. During routine counselling, women who independently selected to use LNG-IUS 12 were invited to participate in the study. KYSS assessed LNG-IUS 12 satisfaction, continuation and safety. RESULTS Overall, there were 1126 successful LNG-IUS 12 placements, with insertion attempted in 1129 women. Most participants (833/968, 86.1%, 95% CI 83.7-88.2%, with satisfaction outcome data available) reported satisfaction with LNG-IUS 12 at 12 months (or at the final visit if the device was discontinued prematurely). Satisfaction was not associated with age, parity or motivation for choosing LNG-IUS 12. The majority of women (919/1129, 81.4%) chose to continue after 12 months. Discontinuation was not correlated with age or parity. Overall, 191 women (16.9%) reported a treatment-emergent adverse event. CONCLUSIONS Results from KYSS provide the first real-world evidence assessing LNG-IUS 12, and demonstrate high satisfaction and continuation rates irrespective of age or parity. Clinical trial registration: NCT03182140.

Reprod Health 2021; 18:176. [PMID: 34454512 PMCID: PMC8401065 DOI: 10.1186/s12978-021-01222-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 08/06/2021] [Indexed: 11/10/2022] Open
Abstract
Background Implanon is an effective form of long-acting reversible contraceptive used to prevent conception with a clinical failure rate of less than one per 100 users. However, in sub-Saharan countries the utilization of implanon was very low. Regardless of low utilization; its early discontinuation is very common in most developing countries including Ethiopia. Objectives To assess the prevalence of early implanon discontinuation and associated factors among women ever used implanon in Mettu district. Methods A community based cross-sectional study design was conducted from October 11 to December 4, 2020 G C. A total of 430 women were included in the study by systematic random sampling technique. Data were entered into epi data version 3.1 and analyzed by SPSS version 25.0. Descriptive analysis was computed to describe descriptive results. Logistics regression was computed to see the relative effect of factors on the outcome variable. Adjusted odds ratio was calculated with 95% confidence intervals to show strength of association and p-value < 0.05 was used to declare statistical significance. The finding of the study was presented using narrations, tables and chart. Result The total proportion of early implanon discontinuation among 430 mothers was 19.3%. Women who did not counseled about the presence of alternatives methods [AOR = 2.28: 95% CI (1.22–4.26)], women who experienced dizziness after insertion of implanon [AOR = 1.90: 95% CI (1.06–3.43)] and being having menstrual disturbance after insertion of implanon [AOR = 2.17: 95% CI (1.16–4.08)] were significantly associated with early implanon discontinuation. Women who were counseled about the advantage of implanon [AOR: 0.49: 95% CI (0.28–0.87)] were protective from early implanon discontinuation. Conclusion and recommendation Early implanon discontinuation among mothers was found to be high. Hence, effective counseling on advantages and side effects of implanon and proper management of the side effects should be made to increase implanon retention. Worldwide, a large number of women become exposed to the risk of conception after contraceptive discontinuation. Besides its low utilization, the discontinuation rate of implanon in developing country was high including Ethiopia. There is no study conducted in south western Ethiopia which shows the magnitude and associated factors of early implanon discontinuation. Therefore, this article provides level of early implanon discontinuation and factors associated with early discontinuation within 1 year’s duration. In this study, a cross-sectional design and interviewer administered questionnaire was employed among 430 women’s of ever used implanon in Mettu district woreda Ilu Aba Bor Zone. The finding of this study revealed that, Women who did not counseled on the presence of alternatives methods, women who experienced dizziness after insertion of implanon and being having menstrual disturbance after insertion of implanon were significantly associated with early implanon discontinuation. Women who were counseled about the advantage of implanon were protective from early implanon discontinuation. In conclusion, the finding of this study reported a high magnitude of early implanon discontinuation as compared to other previous studies.

Abstract
Background Women choosing a levonorgestrel-releasing intrauterine system may experience changes in their menstrual bleeding pattern during the first months following placement. Objective Although health care professionals (HCPs) can provide counseling, no method of providing individualized information on the expected bleeding pattern or continued support is currently available for women experiencing postplacement bleeding changes. We aim to develop a mobile phone–based medical app (MyIUS) to meet this need and provide a digital companion to women after the placement of the intrauterine system. Methods The MyIUS app is classified as a medical device and uses an artificial intelligence–based bleeding pattern prediction algorithm to estimate a woman’s future bleeding pattern in terms of intensity and regularity. We developed the app with the help of a multidisciplinary team by using a robust and high-quality design process in the context of a constantly evolving regulatory landscape. The development framework consisted of a phased approach including ideation, feasibility and concept finalization, product development, and product deployment or localization stages. Results The MyIUS app was considered useful by HCPs and easy to use by women who were consulted during the development process. Following the launch of the sustainable app in selected pilot countries, performance metrics will be gathered to facilitate further technical and feature updates and enhancements. A real-world performance study will also be conducted to allow us to upgrade the app in accordance with the new European Commission Medical Device legislation and to validate the bleeding pattern prediction algorithm in a real-world setting. Conclusions By providing a meaningful estimation of bleeding patterns and allowing an individualized approach to counseling and discussions about contraceptive method choice, the MyIUS app offers a useful tool that may benefit both women and HCPs. Further work is needed to validate the performance of the prediction algorithm and MyIUS app in a real-world setting.

Abstract
Introduction The maternal mortality ratio (MMR) in Indonesia reaches 359 per 100,000 live births. The long-acting reversible contraceptive (LARC) method is an effective contraceptive choice for reducing MMR. The contraceptive implant is one of the LARCs that has low usage due to lack of education about the side effects. This study aims to compare the menstrual pattern and characteristics between one-rod and two-rod levonorgestrel implant users. Methods A prospective cohort study was performed in patients at Cipto Mangunkusumo Hospital (RSCM) from March 2016 to May 2018. Subject recruitment was done by consecutive sampling. This study was conducted from March 2016 until May 2019. Statistical analysis was performed on the data using the chi-square test to determine the relationship between menstrual pattern and characteristics, and the use of one-rod or two-rod levonorgestrel implants. Results A total of 140 subjects participated in the study, comprising 70 (50%) one-rod users and 70 (50%) two-rod users. In the first month, 32.9% one-rod users experienced amenorrhea, 22.9% experienced shortened menstrual period, 30% experienced normal menstrual period, and 14,2 % experienced lengthened menstrual period. In comparison, in the first month, 41.4% two-rod users experienced amenorrhea, 15.7% experienced shortened menstrual period, 32.9% experienced normal menstrual period, and 10% experienced lengthened menstrual period. There was no significant difference in menstrual patterns and characteristics between one-rod and two-rod levonorgestrel implant users. Conclusion There was no significant difference in menstrual patterns and characteristics between one-rod and two-rod levonorgestrel implant users. Implications. Menstrual patterns and characteristics from levonorgestrel implants user can help clinicians to reduce discontinuation rate from the acceptors. Further research should be conducted to know other side effects aside from menstrual bleeding patterns.

Abstract
BACKGROUND Unintended pregnancies (UIP) have a significant impact on health of women and the health budget of countries. Contraception is an effective way to prevent UIPs. The study objective was to collate evidence on clinical effectiveness of etonogestrel subdermal implant (ESI), continuation rate and side effect profile among eligible women of reproductive age group, as compared to levonorgestrel intrauterine system (LNG-IUS), copper intrauterine device (Cu-IUD) and depot medroxy progesterone acetate injections; other types of contraceptive implants were excluded as comparators. METHODS The protocol of the systematic review was registered in Prospero (registration number: CRD42018116580). MEDLINE via PubMed, Cochrane library and web of science were the electronic databases searched. A search strategy was formulated and studies from 1998 to 2019 were included. Clinical trial registries and grey literature search was done. Critical assessment of included studies was done using appropriate tools. A qualitative synthesis of included studies was done and a meta-analysis was conducted in RevMan software for continuation rates of ESI as compared to other long acting reversible contraceptives (LARC) e.g. LNG IUS and Cu-IUD. RESULTS The search yielded 23,545 studies. After excluding 467 duplicates, 23,078 titles were screened and 51 studies were included for the review. Eight of the 15 studies reporting clinical effectiveness reported 100% effectiveness and overall pearl index ranged from 0 to 1.4. One-year continuation rates ranged from 57-97%; 44-95% at the end of second year and 25-78% by 3 years of use. Abnormal menstruation was the most commonly reported side effect. There was no significant difference in bone mineral density at 1 year follow-up. The meta-analyses showed that odds ratio (OR) of 1-year continuation rate was 1.55 (1.36, 1.76) for LNG-IUS vs. ESI and 1.34 (1.13, 1.58) for copper-IUD vs. ESI; showing that continuation rates at the end of one-year were higher in LNG-IUS and copper-IUD as compared to ESI. CONCLUSION ESI is clinically effective and safe contraceptive method to use, yet 1-year continuation rates are lower as compared to LNG-IUS and copper-IUD, mostly attributed to the disturbances in the menstruation.

Abstract
PURPOSE To develop a bleeding-pattern prediction model to inform counselling on amount and regularity of bleeding after levonorgestrel-releasing intrauterine system (LNG-IUS) placement. MATERIALS AND METHODS Fixed-cluster and regression-tree models were developed using bleeding data pooled from two clinical trials of LNG-IUSs. Models were trained and cross-validated on LNG-IUS 12 data, then applied to LNG-IUS 20 and LNG-IUS 8 data. Three clusters were generated for the fixed-cluster model: predominantly amenorrhoea; predominantly spotting; and predominantly bleeding. A random-forest model predicted the future-bleeding cluster, then the probability of cycle regularity was calculated. In the regression-tree model, women were assigned by the model to less- or more-bleeding groups. RESULTS With LNG-IUS 12 (n = 1351) in the fixed-cluster model, 70.4% of women were correctly classified. The correct classification rates for LNG-IUS 20 (n = 216) and LNG-IUS 8 (n = 1300) were 72.2% and 69.0%. The probability distribution for cycle regularity showed regular and irregular bleeding were best separated with LNG-IUS 12 data, and less well with LNG-IUS 20 and LNG-IUS 8 data. In the regression-tree model there was high variability in the more- and less-bleeding group distributions with LNG-IUS 12 data. CONCLUSIONS A fixed-cluster model predicted bleeding patterns better than a regression-tree model in women using LNG-IUS, yielding understandable, informative output.

Abstract
BACKGROUND Since 2013, the residents of the city of Vantaa, Finland, have been offered their first long-acting reversible contraceptive method (levonorgestrel-releasing intrauterine system, implant, and copper intrauterine device) free of charge. OBJECTIVE The primary aim of this study was to assess the 2-year cumulative discontinuation rates of long-acting reversible contraceptive methods when provided free of charge for first-time users in a real-world setting. Additional aims were to describe factors associated with discontinuation and to evaluate the reasons for discontinuation. STUDY DESIGN This is a retrospective register-based cohort study of 2026 nonsterilized women aged 15 to 44 years, who initiated a free-of-charge long-acting contraceptive method in 2013-2014 in the city of Vantaa. Removals within 2 years after method initiation and reasons for discontinuation were obtained from electronic health records and from national registers. We calculated the 2-year cumulative incidence rates of discontinuation with 95% confidence intervals for each method. Furthermore, we assessed crude and adjusted incidence rate ratios of discontinuation with 95% confidence interval by Poisson regression models comparing implants and copper intrauterine device with levonorgestrel-releasing intrauterine systems. RESULTS During the 2 -year follow-up, 514 women discontinued, yielding a cumulative discontinuation rate of 28.3 per 100 women-years (95% confidence interval, 26.2-30.4). Among the 1199 women who initiated the levonorgestrel-releasing intrauterine system, the cumulative discontinuation rate was 24.2 per 100 women-years (95% confidence interval, 21.7-26.9); among the 642 implant users, 33.3 per 100 women-years (95% confidence interval, 29.5-37.4); and among the 185 copper intrauterine device users, 37.8 per 100 women-years (95% confidence interval, 31.0-45.7). Compared with women aged 30 to 44 years, women aged 15 to 19 years (adjusted incidence rate ratio, 1.58; 95% confidence interval, 1.17-2.14) and 20 to 29 years (adjusted incidence rate ratio, 1.35; 95% confidence interval, 1.11-1.63) were more likely to discontinue. We observed a higher discontinuation rate in women who had given birth within the previous year (adjusted incidence rate ratio, 1.36; 95% confidence interval, 1.13-1.65), spoke a native language other than Finnish or Swedish (adjusted incidence rate ratio, 1.31; 95% confidence interval, 1.06-1.63), and had a history of a sexually transmitted infection (adjusted incidence rate ratio, 1.62; 95% confidence interval, 1.07-2.46). No association was found in marital status, overall parity, history of induced abortion, socioeconomic status, education level, or smoking status. The most common reason for discontinuation was bleeding disturbances, reported by 21% of women who discontinued the levonorgestrel-releasing intrauterine system, by 71% who discontinued the implant, and by 41% who discontinued the copper intrauterine device. One in 4 women who discontinued the copper intrauterine device reported heavy menstrual bleeding, whereas only 1% who discontinued the levonorgestrel-releasing intrauterine system and none who discontinued implants reported this reason. Abdominal pain was the reported reason for discontinuation in 20% of both intrauterine device users and in only 2% who discontinued implants. CONCLUSION At 2 years, the use of implants and copper intrauterine devices was more likely to be discontinued than that of the levonorgestrel-releasing intrauterine system. Women younger than 30 years and those who gave birth in the preceding year, spoke a native language other than Finnish or Swedish, or had a history of sexually transmitted infections were more likely to discontinue. The levonorgestrel-releasing intrauterine system was least likely to be removed owing to bleeding disturbances.

Best Practices for Counseling Adolescents about the Etonogestrel Implant. J Pediatr Adolesc Gynecol 2020; 33:448-454. [PMID: 32621879 DOI: 10.1016/j.jpag.2020.06.022] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Revised: 06/22/2020] [Accepted: 06/26/2020] [Indexed: 01/11/2023]
Abstract
Among young persons, ease of use, high efficacy, and high acceptability makes the etonogestrel contraceptive implant an important choice for this age group. Adolescent-friendly, patient-centered counseling considers the patient's cognitive development, the influence of friends and family, as well as their own preferences and values. Age-appropriate language, graphics, and models are useful to explain contraceptive options and relevant side effects. Effectiveness, reversibility, safety, noncontraceptive benefits, and side effects are important attributes and should be discussed when teens are choosing a contraceptive method. In this review we describe suggested best practices for counseling adolescents about the etonogestrel implant so they can make informed, prudent decisions about using this contraceptive method.

Abstract
Background The use of implants has steadily increased in Kinshasa since 2013 but clinic-based access to this family planning method is limited due to distance and costs barriers. The objective of this study was to examine the feasibility and acceptability of providing Implanon NXT at the community level using medical and nursing students (M/N) as distributors, as part of a strategy to improve contraceptive uptake in the Democratic Republic of Congo. Methods A cohort of 531 women who chose to receive Implanon NXT from a M/N student during community-based campaign days participated in three rounds of a quantitative survey administered at the time of insertion of the method, and at 6 and 12 months later. We conducted descriptive analysis to assess the feasibility and acceptability of providing the method through M/N students in terms of method choice, user profiles, contraceptive history, experience with insertion and side effects, continuation / discontinuation of the method, and overall satisfaction with FP services as well as students’ preparedness and capacity to safely offer the method, and their satisfaction with the experience.. Results The study demonstrated the feasibility of training students for community-based provision of Implanon NXT and 95% of them were satisfied with their experience. Acceptability of both the method and the service delivery strategy was high among participants, including among young and first-time contraceptive users. Out of the 441 women with a known outcome at 12 months, 92% still had Implanon NXT inserted, despite some of them reporting experiencing side effects. The vast majority (79%) would “strongly recommend” obtaining NXT from a M/N student if a friend wanted to avoid pregnancies. Conclusions The provision of Implanon NXT at the community-level is a promising solution to address some of the barriers to accessing this method for women living in Kinshasa. However, strengthening pre-insertion counseling, particularly on expected side-effects and the possibility of early removal, is necessary to increase informed choice for the women and potentially limit method discontinuation.

Menstrual bleeding and spotting with the Levonorgestrel Intrauterine System (52 mg) during the first-year after insertion: a systematic review and meta-analysis. Am J Obstet Gynecol 2020; 222:451-468.e9.

Abstract
BACKGROUND Changes in menstrual bleeding concern many users of the 52 mg Levonorgestrel Intrauterine System. Prescribing information for Levonorgestrel Intrauterine System devices describe an overall decrease in bleeding and spotting days over time; however, estimates derived from a variety of existing clinical data are currently unavailable. OBJECTIVE The objective of the study was to systematically calculate the mean days of bleeding-only, spotting-only, and bleeding and/or spotting experienced by a population of reproductive-aged Levonorgestrel Intrauterine System users with normal regular menses prior to insertion during the first year of use. DATA SOURCES We identified clinical trials, including randomized controlled trials and randomized comparative trials, as well as cohort studies published in English between January 1970 and November 2018 through searching 12 biomedical and scientific literature databases including MEDLINE and ClinicalTrials.gov. STUDY ELIGIBILITY CRITERIA We considered studies that reported data on Levonorgestrel Intrauterine System devices releasing 20 μg of levonorgestrel per day, collected daily menstrual bleeding data for at least 90 consecutive days, defined bleeding and spotting per World Health Organization standards and evaluated participants with normal regular menses prior to insertion. STUDY APPRAISAL AND SYNTHESIS METHODS We assessed study quality using established guidelines. Two reviewers independently conducted all review stages and rated the quality of evidence for each article; any disagreements were resolved by a third. Where possible, we pooled data using a random-effects model. RESULTS Among 3403 potentially relevant studies, we included 7 in our meta-analysis. We calculated the mean days of bleeding-only, spotting-only, and bleeding and/or spotting for the first four 90 day intervals after Levonorgestrel Intrauterine System insertion. Combined menstrual bleeding and/or spotting days gradually decreased throughout the first year, from 35.6 days (95% confidence interval, 32.2-39.1) during the first 90 day interval to 19.1 (95% confidence interval, 16.6-21.5), 14.2 (95% confidence interval, 11.7-16.8), and 11.7 days (95% confidence interval, 9.7-13.7) in the second, third, and fourth intervals. Measures for bleeding-only and spotting-only days similarly decreased throughout the first year, with the greatest decreases occurring between the first and second intervals. CONCLUSION Our study provides 90 day reference period measures that characterize menstrual patterns for Levonorgestrel Intrauterine System users with normal regular menses prior to insertion during the first year of use. Our findings provide broader generalizability and more detail than patterns described in the prescribing information. These findings quantify an overall decrease in menstrual bleeding days with longer duration of use, with the greatest decrease occurring between months 3 and 6. Accurately establishing expectations with the Levonorgestrel Intrauterine System may improve informed selection and decrease discontinuation.

AUST HEALTH REV 2020; 44:385-391. [DOI: 10.1071/ah18190] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Accepted: 07/08/2019] [Indexed: 11/23/2022]
Abstract
Objective
Long-acting reversible contraception (LARC) is the most effective form of reversible contraception, but its use in Australia is low compared with other countries. The aim of this study was to evaluate the economic effect of an increase in LARC uptake to international rates.
Methods
An economic model was designed to assess two scenarios, namely increasing the current rate of LARC uptake of 12.5% to the international benchmark of 14.8% among: (1) women currently using the oral contraceptive pill (OCP); and (2) women at risk of pregnancy and not using contraception. Model inputs included cost of contraceptive methods, discontinuation rates and abortion and miscarriage costs associated with unintended pregnancies.
Results
Women who switch from an OCP to LARC would save A$114–157 per year. Those not currently using any contraception who adopt LARC would incur costs of A$36–194 per year, but would reap savings from the reduction in unintended pregnancies. Over 5 years there would be a net saving of A$74.4 million for Scenario 1 and A$2.4 million for Scenario 2.
Conclusion
Greater use of LARC would result in a net gain in economic benefits to Australia. These benefits are largely driven by women switching from an OCP to LARC who have reduced costs, as well as women wishing to avoid pregnancy who choose to use LARC rather than no method. This evidence will support women making an informed contraceptive choice and policy makers in increasing the accessibility of LARC.
What is known about the topic?
LARC is the most effective form of reversible contraception, but uptake in Australia is relatively low.
What does this paper add?
There are economic benefits to society for women who switch from an OCP to LARC, as well as for women who switch from no contraception to LARC.
What are the implications for practitioners?
The findings of this study will support women in making an informed contraceptive choice and policy makers in increasing the accessibility of LARC.

Abstract
Objective: To investigate differences in continuation rates between contraceptive and therapeutic use of the levonorgestrel-releasing intrauterine system 52 mg (LNG-IUS) and factors associated with early removal.Methods: Study design: Retrospective consecutive cohort design.Cohort: Women with the insertion of the LNG-IUS for contraceptive or therapeutic use from 1 January 2006 through 1 January 2009 at the Zuyderland Medical Centre, The Netherlands, with a follow-up of 5 years. The continuation period and reasons of early removal were noted. Univariable and multivariable analysis were performed.Results: Follow-up was possible in 2481 women, 1855 (74.8%) in the contraception group, and 626 (25.2%) in the therapy group. Multivariable Cox proportional hazards models showed, that therapeutic use was associated with an increased risk of early removal of the LNG-IUS (HR 1.23; 95% CI 1.08-1.41), as was having one child (HR 1.20; 95% CI 1.04-1.38), and a decreased risk with advancing age (HR 0.96; 95% CI 0.95-0.97). In both groups, an unacceptable bleeding pattern and adverse events were the main reasons of early removal, resulting in very low continuation rates over the years.Conclusion: Therapeutic use, having one child and a younger age are independent risk factors of early removal of the LNG-IUS, in contrast with previous LNG-IUS use which is associated with a lower risk. In both the contraception group and the therapy group, the main reasons for LNG-IUS discontinuation are continuation with a new LNG-IUS, and no more need for an LNG-IUS (for contraception or therapy). An unacceptable bleeding pattern or adverse events are associated with the lowest continuation rates in both groups.

Abstract
OBJECTIVE DATA Amenorrhea is a polarizing noncontraceptive effect of the levonorgestrel intrauterine system. Composite amenorrhea prevalence estimates that summarize all clinical data for the first-year after insertion currently are not available. The purpose of this study was to investigate the validity of existing prevalence estimates by the systematic calculation of amenorrhea measures for a general population of levonorgestrel intrauterine system users and to provide 90-day interval point estimates for the first year of use. STUDY We identified clinical trials, randomized controlled trials, and randomized comparative trials that were published in English between January 1970 and September 2017 through electronic searches of 12 biomedical and scientific literature databases that included MEDLINE and ClinicalTrials.gov. STUDY APPRAISAL AND SYNTHESIS METHODS We considered studies that clearly defined amenorrhea per World Health Organization standards (the complete cessation of bleeding for at least 90 days), collected data from written daily bleeding diaries (the gold standard data collection technique on menstrual bleeding changes), and evaluated levonorgestrel intrauterine system devices that released 20 μg of levonorgestrel per day. We assessed study quality using guidelines established by the US Preventive Services Task Force and Cochrane handbook for systematic reviews of interventions. Two reviewers independently conducted all review stages; disagreements were resolved by a third reviewer. Where possible, data were pooled with the use of a random-effects model. RESULTS Of 2938 potentially relevant studies, we included 9 in our meta-analysis. We calculated amenorrhea prevalence, which was weighted for inter- and intrastudy variance, for 4 90-day intervals and months 0-12. Our results demonstrated few levonorgestrel intrauterine system users (0.2%; 95% confidence interval, 0.0-0.4) experienced amenorrhea during the first 90 days after insertion; however, prevalence increased to 8.1% (95% confidence interval, 6.6-9.7) on days 91-180. Finally, 18.2% (95% confidence interval, 14.9-21.5) of users experienced amenorrhea for at least 1 90-day interval during the first year. Although interstudy heterogeneity limited reliability of days 181-271 and 272-365 measures, prevalence increased from 13.6% (95% confidence interval, 9.3-18.0) to 20.3% (95% confidence interval, 13.5-27.0), respectively. CONCLUSION Approximately 20% of levonorgestrel intrauterine system users experience amenorrhea during at least 1 90-day interval by the first year after insertion. This composite estimate is consistent with the product labeling and demonstrates that most users do not experience amenorrhea during the first year. These results provide accurate summary measures to facilitate counselling and informed method selection.

Abstract
OBJECTIVE To develop a greater understanding of the motivators of contraceptive method change over time for young Australian women, with a particular interest in long-acting reversible contraception (LARC) use. METHOD Free-text comments from the Contraceptive Use, Pregnancy Intention and Decisions (CUPID) Study were used to explore the reasons for contraceptive method change among women who reported one or more contraceptive changes across the three CUPID surveys. RESULTS 512 women reported making at least one contraceptive method change, with 740 comments explaining these changes between them. Participants reported a multitude of reasons motivating their contraceptive change. Five key themes were developed to explain these motivators: the natural, sexual and fertile body, specific contraceptive characteristics and other important people. Findings suggest that women's decisions to switch or discontinue a contraceptive depended largely on her ability (and desire) to juggle its impact on her sexual, fertile and natural body. Importantly, the transient and fluid nature of contraceptive practices were demonstrated, as the women adjusted their method to suit their needs at the time. CONCLUSION Regarding LARC use, these findings suggest that rather than being appealing, the 'temporarily permanent' nature of these methods may be unappealing and incongruent with the needs of some women.

Abstract
Background Unplanned pregnancy is a significant problem in Australia. Local data pertaining to use of the levonorgestrel-releasing intra-uterine device (LNG-IUD), and associated factors are limited. The aim of this analysis was to calculate prescribing rates of the LNG-IUD in Australia, including trends in prescribing and associations with socio-demographic factors, in order to increase understanding regarding potential use. Methods We examined prescriptions for the LNG-IUD recorded in the national Pharmaceutical Benefits Scheme (PBS) from 2008 to 2012. Prescribing trends were examined according to patient age, remoteness of residential location, and proximity to relevant specialist health services. Associations between these factors and prescription rates were examined using poisson regression. Analyses were stratified by 5-year age-groups. Results Age-adjusted prescription rates rose from 11.50 per 1000 women aged 15–49 (95% CI: 11.41–11.59) in 2008 to 15.95 (95% CI:15.85–16.01) in 2012. Prescription rates increased most among 15–19-year-olds but remain very low at 2.76 per 1000 women (95% CI: 2.52–3.01). Absolute increases in prescriptions were greatest among 40–44-year-olds, rising from 16.73 per 1000 women in 2008 (95% CI: 16.12–17.34) to 23.77 in 2012 (95% CI: 22.58–24.29). Rates increased significantly within all geographical locations (p < 0.01). Non-metropolitan location was significantly associated with increased prescribing rates, the association diminishing with increasing age groups. Conclusions Prescription of LNG-IUD in Australia is very low, especially among young women and those in major cities. Service providers and young women may benefit from targeted education outlining use of the LNG-IUD, strengthened training and referral pathways. Disparities in prescription according to location require further investigation.

Abstract
INTRODUCTION Contraceptives improve women's lives and public health, but many women discontinue their contraceptive method owing to dissatisfaction. An underexamined aspect of contraceptive discontinuation is sexual acceptability, or how contraception affects sexual experiences. Investigators' aims were two-fold: 1) to document changes in multiple domains of women's sexual experiences with their intrauterine device (IUD) or contraceptive implant over time and 2) to examine whether these sexuality factors were associated with method continuation at 12 months. METHODS We enrolled 200 eligible family planning clients and collected data at baseline and at 1, 3, 6, and 12 months. Sexual acceptability measures included the Female Sexual Function Index-6, the New Sexual Satisfaction Scale, and participants' perceptions of whether their contraceptive method had had a neutral, positive, or negative effect on their sex life. Survival analysis and Cox regression with time-varying covariates related sexuality measures to method continuation over time while controlling for other relevant factors. RESULTS Among 193 women who received an IUD or implant, 20% selected the copper IUD, 46% the levonorgestrel IUD, and 34% the etonogestrel implant. Ten percent discontinued their method during the year. Although changes in Female Sexual Function Index-6 and New Sexual Satisfaction Scale scores were not associated with discontinuation, individuals who perceived that their method detracted from their sexual experience had significantly higher removal rates than those who reported no sexual changes or positive sexual changes (adjusted hazard ratio, 8.04; 95% CI, 1.53-42.24), even when controlling for method type, bleeding changes, and a variety of covariates and controls. CONCLUSIONS Although limited by the small sample of discontinuers, we found that women's perceptions of how their method affects their sex life were associated with contraceptive continuation over time. Sexual acceptability should receive more attention in both contraceptive research and counseling.

Abstract
INTRODUCTION Concern about side effects and health issues are common reasons for contraceptive non-use or discontinuation. Contraceptive-induced menstrual bleeding changes (CIMBCs) are linked to these concerns. Research on women's responses to CIMBCs has not been mapped or summarized in a systematic scoping review. METHODS We conducted a systematic scoping review of data on women's responses to CIMBCs in peer-reviewed, English-language publications in the last 15 years. Investigator dyads abstracted information from relevant studies on pre-specified and emergent themes using a standardized form. We held an expert consultation to obtain critical input. We provide recommendations for researchers, contraceptive counselors, and product developers. RESULTS We identified 100 relevant studies. All world regions were represented (except Antarctica), including Africa (11%), the Americas (32%), Asia (7%), Europe (20%), and Oceania (6%). We summarize findings pertinent to five thematic areas: women's responses to contraceptive-induced non-standard bleeding patterns; CIMBCs influence on non-use, dissatisfaction or discontinuation; conceptual linkages between CIMBCs and health; women's responses to menstrual suppression; and other emergent themes. Women's preferences for non-monthly bleeding patterns ranged widely, though amenorrhea appears most acceptable in the Americas and Europe. Multiple studies reported CIMBCs as top reasons for contraceptive dissatisfaction and discontinuation; others suggested disruption of regular bleeding patterns was associated with non-use. CIMBCs in some contexts were perceived as linked with a wide range of health concerns; e.g., some women perceived amenorrhea to cause a buildup of "dirty" or "blocked" blood, in turn perceived as causing blood clots, fibroids, emotional disturbances, weight gain, infertility, or death. Multiple studies addressed how CIMBCs (or menstruation) impacted daily activities, including participation in domestic, work, school, sports, or religious life; sexual or emotional relationships; and other domains. CONCLUSIONS Substantial variability exists around how women respond to CIMBCs; these responses are shaped by individual and social influences. Despite variation in responses across contexts and sub-populations, CIMBCs can impact multiple aspects of women's lives. Women's responses to CIMBCs should be recognized as a key issue in contraceptive research, counseling, and product development, but may be underappreciated, despite likely - and potentially substantial - impacts on contraceptive discontinuation and unmet need for modern contraception.

Abstract
Background Access to most contraceptives in Australia requires a prescription from a doctor, and it has been shown that doctors can influence women’s decision-making with respect to contraception. However, little research has documented how women experience their interactions with doctors within the context of a contraceptive consultation. Understanding such experiences may contribute to our knowledge of factors that may influence women’s contraceptive decisions more broadly. Methods We report on findings from the Contraceptive Use, Pregnancy Intentions and Decisions (CUPID) survey of young Australian women, a large-scale longitudinal study of 3,795 women aged 18–23 years. We performed a computer-assisted search for occurrences of words that indicated an interaction within the 1,038 responses to an open-ended question about contraception and pregnancy. We then applied a combination of conventional and summative content analysis techniques to the 158 comments where women mentioned an interaction about contraception with a doctor. Results Our analysis showed that women desire consistent and accurate contraception information from doctors, in addition to information about options other than the oral contraceptive pill. Some young women reported frustrations about the choice limitations imposed by doctors, perceived by these women to be due to their young age. Several women expressed disappointment that their doctor did not fully discuss the potential side-effects of contraceptives with them, and that doctors made assumptions about the woman’s reasons for seeking contraception. Some women described discomfort in having contraception-related discussions, and some perceived their doctor to be unsupportive or judgmental. Conclusions Both the content and the process of a contraceptive consultation are important to young Australian women, and may be relevant contributors to their choice and ongoing use of a contraceptive method. These findings provide useful insights into aspects of the patient-provider interaction that will enhance the efficacy of the contraceptive consultation. It is recommended that doctors adopt patient-centred, shared decision-making strategies to support women in making choices about contraception that suit their individual circumstances. We also acknowledge the need to involve other health care providers, other than doctors, in educating, informing, and assisting women to make the best contraceptive choice for themselves.

Abstract
BACKGROUND Copper intrauterine device (Cu-IUD) use in Australia is low despite being a highly effective, cost effective non-hormonal contraceptive with reported 12-month continuation rates of 85% compared to 59% for oral contraception. AIMS To describe the characteristics of Cu-IUD users in the Australian context, their experiences of side effects, continuation rates and reasons for discontinuation. METHODS Between August 2009 and January 2012 we undertook a prospective cohort study of consecutive women presenting for Cu-IUD insertion to three family planning clinics in Queensland and New South Wales. We used survival analysis for continuation rates and univariate and multivariable analyses to characterise users, their experiences up to three years and reasons for discontinuation. RESULTS Of the 211 enrolled women, a third (36.0%) were aged under 30 and a third were nulliparous (36.5%). Efficacy and lack of hormones were the most frequently cited reasons to choose the method. Four women were lost to follow-up. Overall continuation rates were 79.1% at one year and 61.3% at three years. Early discontinuation was reduced in those with two or more children (adjusted hazards ratio 0.22, 95% CI 0.09-0.50). Heavy menstrual bleeding was the commonest reason for removal in 28 of 59 (47.5%) discontinuations due to complications or side effects. One uterine perforation and one method failure resulting in an ectopic pregnancy occurred. CONCLUSIONS Cu-IUDs were chosen for their efficacy and lack of hormones by a range of Australian women, including young and nulliparous women. While bleeding-related side effects were relatively common, overall continuation rates were high. Serious complications and failures were rare.

Abstract
STUDY QUESTION Is it possible to extend the use of the 3-year one-rod etonogestrel (ENG)-releasing subdermal contraceptive implant to 5 years? SUMMARY ANSWER The extended use of the one-rod ENG-releasing subdermal contraceptive implant showed 100% efficacy in years 4 and 5. WHAT IS KNOWN ALREADY The initial regulated trials on the ENG-releasing subdermal contraceptive implant conducted in the 1990 s were designed to measure cumulative 3-year efficacy. The ENG-implant has both well established safety and efficacy for up to 3 years. Pharmacokinetic data on ENG show high levels at 3 years and some previous clinical research confirms efficacy beyond the current approved duration of 3 years. Today, many women, because the labeled duration has been reached, have the ENG implant removed at 3 years, increasing costs, inconvenience and risks. STUDY DESIGN SIZE, DURATION For the first 3 years, this study was an open-label, multi-centre randomized trial comparing the 3-year ENG implant to the 5-year levonorgestrel (LNG)-releasing implant. After 3 years, a subset of 390 ENG participants, consented to extended use. We compared efficacy, side effects and removal procedures of both implants. We used Kaplan–Meier (K–M) analysis. We included an observational cohort of copper intrauterine device (IUD) users as non-users of hormonal contraceptive method for comparative purposes. PARTICIPANTS/MATERIALS, SETTING, METHODS The study took place in family planning clinics in seven countries worldwide. Women were enlisted after an eligibility check and informed consent, and 1328 women were enrolled: 390, 522 and 416 in the ENG-implant, LNG-implant and IUD groups, respectively. MAIN RESULTS AND THE ROLE OF CHANCE Over 200 women used the ENG implant for at least 5 years. No pregnancies occurred during the additional 2 years of follow up in the ENG or LNG implant group. The overall 5-year K–M cumulative pregnancy rates for ENG- and LNG- implants were 0.6 per 100 women-years (W-Y) [95% confidence interval (CI): 0.2–1.8] and 0.8 per 100 W-Y [95% CI: 0.2–2.3], respectively. Complaints of bleeding changes were similar; however, ENG-users were more likely than LNG-users to experience heavy bleeding (p < 0.05). The median duration of the implant removal procedure was 64 seconds shorter for the one-rod ENG-implant (inter-quartile range (IQR) = 30.5, 117.5) compared to the two-rod LNG product (IQR = 77.0, 180.0). The 2-year rate for pregnancy in the IUD group compared with the two implant groups combined was 4.1 per 100 W-Y [95% CI: 2.5–6.5]. LIMITATIONS, REASONS FOR CAUTION Few women were ≤19 years old or nulligravida. Although there was no weight limit for enrolment in the study, the number of women ≥70 kg were few. WIDER IMPLICATIONS OF THE FINDINGS The results from this study corroborate previous evidence showing high contraceptive efficacy through 4 years for the ENG-implant. Data through 5 years are a novel contribution and further proof of the product's capability to provide safe and effective contraception that rivals the current 5-year LNG-subdermal implant. The findings provide valuable information for policy makers, family planning programmers and clinicians that the ENG-releasing subdermal implant is still highly effective up to 5 years after insertion. Compared to previous efforts, our study population was geographically diverse and our study had the highest number of participants completing at least 5 years of use. TRIAL REGISTRATION The trial was registered as ISRCTN33378571. STUDY FUNDING/COMPETING INTEREST(S) The contraceptive devices and funds for conduct of the study were provided by the United Nations Development Programme/United Nations Population Fund/World Health Organization (WHO)/UNICEF/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), Department of Reproductive Health and Research (RHR), WHO. This report contains the collective views of an international group of experts, and does not necessarily represent the decisions or the stated policy of the WHO. All stated authors have no conflict of interest, except Dr Hubacher who reported grants from United States Agency for International Development, during the conduct of the study; other from Advisory Boards (Teva, Bayer, OCON), outside the submitted work.

Abstract
BACKGROUND Long-acting reversible contraception is more effective for pregnancy prevention than shorter-acting contraceptive methods and has the potential to reduce healthcare disparities and costs. However, long-acting reversible contraception is underused in the United States. One population of interest is beneficiaries of the United States military healthcare system who have access to universal healthcare, including no-cost, no-copay contraception with unlimited method switching, and comprise a large, actual use cohort. Efforts to increase long-acting reversible contraception initiation and continuation in this population may improve health outcomes and mitigate the profound consequences of unintended or mistimed pregnancy on readiness and cost to the military. OBJECTIVE We aimed to determine long-acting reversible contraception initiation and continuation rates among the diverse population with universal healthcare who are enrolled in the US military healthcare system. STUDY DESIGN This study is a retrospective cohort of >1.7 million women, aged 14-40 years, who were enrolled in the US military healthcare system, TRICARE Prime, between October 2009 and September 2014. Individuals were assessed for long-acting reversible contraception initiation and continuation with the use of medical billing records. Method continuation and factors that were associated with early method discontinuation were evaluated with the Kaplan-Meier estimator and Cox proportional hazard models. RESULTS During the study dates, 188,533 women initiated long-acting reversible contraception. Of these, 74.6% women selected intrauterine contraceptives. Method initiation rates remained relatively stable (41.7-50.1/1000 women/year) for intrauterine methods, although the rate for subdermal implants increased from 6.1-23.0/1000 women/year. In analysis of women who selected intrauterine contraceptives, 61.2% continued their method at 36 months, and 48.8% continued at 60 months. Among women who selected the implant, 32.0% continued their method at 36 months; however, 45.8% continued until 33 months (ie, 3 months before the currently recommended expiration date). Compared with intrauterine contraceptive users, implant users were more likely to discontinue their method during the 36 months after insertion (hazard ratio, 1.59; 95% confidence interval, 1.56-1.62; P < .001). Adolescents aged 14-19 years were the least likely age group to discontinue the implant before 36 months; women aged 35-40 years were the least likely to discontinue an intrauterine contraceptive before 60 months. In multivariable analysis that controlled for demographic factors and contraceptive type, early contraceptive method discontinuation was most likely among women aged 20-24 years, implant users, and women with method initiation in military clinics. CONCLUSION In the US military healthcare system, TRICARE Prime, the initiation of long-acting reversible contraception is low but increasing, and continuation rates are high. This evidence supports long-acting reversible contraception as first-line recommendations for women of all ages who seek contraception.

Abstract
OBJECTIVE To describe trends in age-specific incidence rates of female sterilization (FS) procedures in Western Australia and to evaluate the effects of the introduction of government-subsidized contraceptive methods and the implementation of the Australian government's baby bonus policy on FS rates. DESIGN Population-based retrospective descriptive study. SETTING Not applicable. PATIENT(S) All women ages 15-49 undergoing an FS procedure during the period January 1, 1990, to December 31, 2008 (n = 47,360 procedures). INTERVENTION(S) Records from statutory statewide data collections of hospitals separations and births were extracted and linked. MAIN OUTCOME MEASURE(S) Trends in FS procedures and the influence on these trends of the introduction of government policies: subsidization of long-acting reversible contraceptives (Implanon and Mirena) and the Australian baby bonus initiative. RESULT(S) The annual incidence rate of FS procedures declined from 756.9 per 100,000 women in 1990 to 155.2 per 100,000 women in 2008. Compared with the period 1990-1994, women ages 30-39 years were 47% less likely (rate ratio [RR] = 0.53; 95% confidence interval [CI], 0.39-0.72) to undergo sterilization during the period 2005-2008. Adjusting for overall trend, there were significant decreases in FS rates after government subsidization of Implanon (RR = 0.89; 95% CI, 0.82-0.97) and Mirena (RR = 0.81; 95% CI, 0.73-0.91) and the introduction of the baby bonus (RR = 0.70; 95% CI, 0.61-0.81). CONCLUSION(S) Rates of female sterilization procedures in Western Australia have declined substantially across all age groups in the last two decades. Women's decisions to undergo sterilization procedures may be influenced by government interventions that increase access to long-term reversible contraceptives or encourage childbirth.

Abstract
Much has been written about the consequences of substance use in pregnancy, but there has been far less focus on the prevention of unintended pregnancies in women with substance use disorders (SUDs). We examine the literature on pregnancy incidence for women with SUDs, the clinical and economic benefits of increasing access to long-acting reversible contraceptive (LARC) methods in this population, and the current hurdles to increased access and uptake. High rates of unintended pregnancies and poor physical and psychosocial outcomes among women with SUDs underscore the need for increased access to, and uptake of, LARC methods among these women. A small number of studies that focused on improving access to contraception, especially LARC, via integrated contraception services predominantly provided in drug treatment programs were identified. However, a number of barriers remain, highlighting that much more research is needed in this area.

Abstract
Medically induced amenorrhea can be achieved through alterations in the normal regulatory hormones via the adoption of a therapeutic agent, which prevents menstrual flow. Spaceflight-related advantages for medically induced amenorrhea differ according to the time point in the astronaut's training schedule. Pregnancy is contraindicated for many pre-flight training activities as well as spaceflight, therefore effective contraception is essential. In addition, the practicalities of menstruating during pre-flight training or spaceflight can be challenging. During long-duration missions, female astronauts have often continuously taken the combined oral contraceptive pill to induce amenorrhea. Long-acting reversible contraceptives (LARCs) are safe and reliable methods used to medically induce amenorrhea terrestrially but as of yet, not extensively used by female astronauts. If LARCs were used, daily compliance with an oral pill is not required and no upmass or trash would need disposal. Military studies have shown that high proportions of female personnel desire amenorrhea during deployment; better education has been recommended at recruitment to improve uptake and autonomous decision-making. Astronauts are exposed to similar austere conditions as military personnel and parallels can be drawn with these results. Offering female astronauts up-to-date, evidence-based, comprehensive education, in view of the environment in which they work, would empower them to make informed decisions regarding menstrual suppression while respecting their autonomy.

The role of decidual cells in uterine hemostasis, menstruation, inflammation, adverse pregnancy outcomes and abnormal uterine bleeding. Hum Reprod Update 2016; 22:497-515.

Abstract
BACKGROUND Human pregnancy requires robust hemostasis to prevent hemorrhage during extravillous trophoblast (EVT) invasion of the decidualized endometrium, modification of spiral arteries and post-partum processes. However, decidual hemorrhage (abruption) can occur throughout pregnancy from poorly transformed spiral arteries, causing fetal death or spontaneous preterm birth (PTB), or it can promote the aberrant placentation observed in intrauterine growth restriction (IUGR) and pre-eclampsia; all leading causes of perinatal or maternal morbidity and mortality. In non-fertile cycles, the decidua undergoes controlled menstrual bleeding. Abnormal uterine bleeding (AUB) accompanying progestin-only, long-acting, reversible contraception (pLARC) accounts for most discontinuations of these safe and highly effective agents, thereby contributing to unwanted pregnancies and abortion. The aim of this study was to investigate the role of decidual cells in uterine hemostasis, menstruation, inflammation, adverse pregnancy outcomes and abnormal uterine bleeding. METHODS We conducted a critical review of the literature arising from PubMed searches up to December 2015, regarding in situ and in vitro expression and regulation of several specific proteins involved in uterine hemostasis in decidua and cycling endometrium. In addition, we discussed clinical and molecular mechanisms associated with pLARC-induced AUB and pregnancy complications with abruptions, chorioamnionitis or pre-eclampsia. RESULTS Progestin-induced decidualization of estradiol-primed human endometrial stromal cells (HESCs) increases in vivo and in vitro expression of tissue factor (TF) and type-1 plasminogen activator inhibitor (PAI-1) while inhibiting plasminogen activators (PAs), matrix metalloproteinases (MMPs), and the vasoconstrictor, endothelin-1 (ET-1). These changes in decidual cell-derived regulators of hemostasis, fibrinolysis, extracellular matrix (ECM) turnover, and vascular tone prevent hemorrhage during EVT invasion and vascular remodeling. In non-fertile cycles, progesterone withdrawal reduces TF and PAI-1 while increasing PA, MMPs and ET-1, causing menstrual-associated bleeding, fibrinolysis, ECM degradation and ischemia. First trimester decidual hemorrhage elicits later adverse outcomes including pregnancy loss, pre-eclampsia, abruption, IUGR and PTB. Decidual hemorrhage generates excess thrombin that binds to decidual cell-expressed protease-activated receptors (PARs) to induce chemokines promoting shallow placentation; such bleeding later in pregnancy generates thrombin to down-regulate decidual cell progesterone receptors and up-regulate cytokines and MMPs linked to PTB. Endometria of pLARC users display ischemia-induced excess vasculogenesis and progestin inhibition of spiral artery vascular smooth muscle cell proliferation and migration leading to dilated fragile vessels prone to bleeding. Moreover, aberrant TF-derived thrombin signaling also contributes to the pathogenesis of endometriosis via induction of angiogenesis, inflammation and cell survival. CONCLUSION Perivascular decidualized HESCs promote endometrial hemostasis during placentation yet facilitate menstruation through progestational regulation of hemostatic, proteolytic, and vasoactive proteins. Pathological endometrial hemorrhage elicits excess local thrombin generation, which contributes to pLARC associated AUB, endometriosis and adverse pregnancy outcomes through several biochemical mechanisms.

Abstract
OBJECTIVE The objective of this analysis was to estimate the 3-year continuation rates of long-acting reversible contraceptive (LARC) methods and to compare these rates to non-LARC methods. STUDY DESIGN The Contraceptive CHOICE Project (CHOICE) was a prospective cohort study that followed 9256 participants with telephone surveys at 3 and 6 months, then every 6 months for 2-3 years. We estimated 3-year continuation rates of baseline methods that were chosen at enrollment. The LARC methods include the 52-mg levonorgestrel intrauterine device; the copper intrauterine device, and the subdermal implant). These were then compared to rates to non-LARC hormonal methods (depot medroxyprogesterone acetate, oral contraceptive pills, contraceptive patch, and vaginal ring). Eligibility criteria for this analysis included participants who started their baseline chosen method by the 3-month survey. Participants who discontinued their method to attempt conception were censored. We used a Cox proportional hazard model to adjust for confounding and to estimate the hazard ratio for risk of discontinuation. RESULTS Our analytic sample consisted of 4708 CHOICE participants who met inclusion criteria. Three-year continuation rates were 69.8% for users of the levonorgestrel intrauterine device, 69.7% for copper intrauterine device users, and 56.2% for implant users. At 3 years, continuation was 67.2% among LARC users and 31.0% among non-LARC users (P < .001). After adjustment for age, race, education, socioeconomic status, parity, and history of sexually transmitted infection, the hazard ratio for risk of discontinuation was 3-fold higher among non-LARC method users than LARC users (adjusted hazard ratio, 3.08; 95% confidence interval, 2.80-3.39). CONCLUSION Three-year continuation of the 2 intrauterine devices approached 70%. Continuation of LARC methods was significantly higher than non-LARC methods.

Abstract
Use of long-acting progestin only contraceptives (LAPCs) offers a discrete and highly effective family planning method. Abnormal uterine bleeding (AUB) is the major side effect of, and cause for, discontinuation of LAPCs. The endometria of LAPC-treated women display abnormally enlarged, fragile blood vessels, decreased endometrial blood flow and oxidative stress. To understanding to mechanisms underlying AUB, we propose to identify LAPC-modulated unique gene cluster(s) in human endometrial stromal cells (HESCs). Protein and RNA isolated from cultured HESCs treated 7 days with estradiol (E2) or E2+ medroxyprogesterone acetate (MPA) or E2+ etonogestrel (ETO) or E2+ progesterone (P4) were analyzed by quantitative Real-time (q)-PCR and immunoblotting. HSCORES were determined for immunostained-paired endometria of pre-and 3 months post-Depot MPA (DMPA) treated women and ovariectomized guinea pigs (GPs) treated with placebo or E2 or MPA or E2+MPA for 21 days. In HESCs, whole genome analysis identified a 67 gene group regulated by all three progestins, whereas a 235 gene group was regulated by E2+ETO and E2+MPA, but not E2+P4. Ingenuity pathway analysis identified glucocorticoid receptor (GR) activation as one of upstream regulators of the 235 MPA and ETO-specific genes. Among these, microarray results demonstrated significant enhancement of FKBP51, a repressor of PR/GR transcriptional activity, by both MPA and ETO. q-PCR and immunoblot analysis confirmed the microarray results. In endometria of post-DMPA versus pre-DMPA administered women, FKBP51 expression was significantly increased in endometrial stromal and glandular cells. In GPs, E2+MPA or MPA significantly increased FKBP51 immunoreactivity in endometrial stromal and glandular cells versus placebo- and E2-administered groups. MPA or ETO administration activates GR signaling and increases endometrial FKBP51 expression, which could be one of the mechanisms causing AUB by inhibiting PR and GR-mediated transcription. The resultant PR and/or GR-mediated functional withdrawal may contribute to associated endometrial inflammation, aberrant angiogenesis, and bleeding.
