Background: Dienogest (DNG) 2 mg/ethinylestradiol (EE) 0.02 mg is the first low-dose combined oral contraceptive (COC) with a prolonged-release formulation that allows stable plasma concentrations and has high contraceptive efficacy (Pearl index: 0.2). The aim of this trial was to determine the bleeding profile of this contraceptive compared to an immediate release formulation.

Methods: This prospective double-blind randomised controlled trial evaluated the bleeding patterns of DNG 2 mg/EE 0.02 mg compared with immediate-release drospirenone (DRSP) 3 mg/EE 0.02 mg in a 24/4-day regimen over nine cycles (randomisation ratio, 5:2). Participants recorded scheduled and unscheduled bleeding/spotting data using an electronic diary. A non-inferiority analysis for the proportion of participants with unscheduled bleeding/spotting was prespecified for Cycles 2-6. Safety, including adverse events, were monitored throughout the trial.

Results: Seven-hundred six and 288 participants received DNG/EE and DRSP/EE, respectively. Scheduled bleeding patterns per each 28-day cycle were similar in both groups. During Cycles 2-6, the proportion of participants with unscheduled bleeding/spotting was significantly lower in the DNG/EE group (50.5% [280/574] than in the DRSP/EE group (72.8% [171/235]]; treatment difference 22.3% [95% CI 15.9, 28.6%]; p < 0.0001). A low proportion of participants discontinued the trial due to bleeding disorders (1.7% and 0.7%, respectively). The safety profiles were similar for both treatments.

Conclusions: The prolonged-release DNG 2 mg/EE 0.02 mg offers a significant decrease in unscheduled bleeding/spotting compared with an immediate-release COC, DRSP/EE, combined with high contraceptive efficacy and a very low adverse event profile.

Introduction: We aim to investigate the relationship between individuals' perceptions of their neighbourhood environment and early menarche.

Methods: This was a retrospective cohort study of 7,486 girls of Ethiopia, India, South Korea, the United Kingdom (UK), and the United States (US), born in 1997-2011 was analysed. Early menarche was defined as being below the 10th to 20th percentiles in each cohort, considering the varying distributions across countries. Perceived neighbourhood environments were assessed based on the responses for neighbourhood pollution, safety, and recreational facilities. We calculated the relative risk (RR) of early menarche for unfavourable environment.

Results: The mean age at menarche was lowest in South Korea (10.6 years) and highest in Ethiopia (13.7 years). Unfavourable environment was associated with higher risk of early menarche overall (RR = 1.34, 95% confidence interval [CI]:1.09-1.65) and each country (3.03, 95% CI: 1.15-7.96 in Ethiopia; 1.99, 95% CI: 0.97-4.10 in India, 1.23, 95% CI: 0.67-2.27 in Korea; 1.26, 95% CI: 0.96-1.64 in the UK). Specifically, pollution (1.29, 95% CI: 1.03-1.62) and low safety (1.19, 95% CI: 1.60-1.88) were associated with early menarche.

Conclusions: Our finding highlights the potential role of perceived neighbourhood environment in the timing of puberty.

Purpose: Annually, approximately 31,000 people experience a termination of pregnancy (TOP) in the Netherlands. In 2021, about one-third of them chose medical termination of pregnancy (MTOP). We explored experiences with MTOP and to what extent expectations, pain, and counselling in the clinic are associated with satisfaction with MTOP.

Materials and methods: A retrospective cross-sectional study was conducted using an online questionnaire. We included 138 respondents, ≥16 years, who chose MTOP (September 2020-March 2022).

Results: The majority of respondents experienced MTOP more positively than expected or as expected (67%). For 24%, the experience was more negative than expected. In the event of another TOP, half of these respondents would hesitate to choose or would not choose MTOP, mainly due to physical side effects. The majority of respondents (73%) would choose MTOP again. Their main motivation was self-determination during treatment. Respondents cited four key elements: pain, intensity of experience during and after treatment, blood loss, and duration. Correspondence between MTOP expectations and experiences was associated with satisfaction with MTOP, while pain and satisfaction with counselling were not.

Conclusions: The majority of respondents were satisfied with MTOP and would choose the treatment again. Non-correspondence between expectations and experiences negatively affected satisfaction with MTOP. This highlights the importance of managing expectations by providing accessible information about the variety in expectations and experiences to patients with a focus on key elements of the experience.

Introduction: Looking after a baby and recovering from birth pose barriers to accessing and initiating effective contraception in the postpartum period. Another pregnancy at this time can end in abortion or a short interbirth interval. These are preventable if contraception is provided immediately from maternity settings. Our aim was to survey contraceptive experts across Europe about provision of postpartum contraception (PPC) in their country to develop a greater understanding of availability of and delivery of PPC services within the region.

Materials and methods: Contraceptive experts across Europe were invited to participate in an anonymous mixed-methods online survey consisting of free text and fixed-response questions focusing on: (1) national guidelines/policy (2) antenatal contraceptive discussion and (3) immediate postpartum provision of methods. Respondents were asked to rate PPC provision in their region and detail perceived facilitators or barriers.

Results: Experts from 28 countries completed the survey. Fifteen (40%) reported their country had national guidelines for PPC provision, 40% reported that some antenatal contraceptive counselling was offered and 51% reported that contraceptive methods were provided in some (43%) or all (8%) maternity settings. Country-level PPC provision was reported as 'poor' or 'very poor' by 54% of respondents. Reported barriers to PPC provision included: cost, lack of policy/government support, awareness and training of maternity staff.

Conclusions: There is significant variation in PPC provision across Europe. Few countries offer antenatal contraceptive counselling or provide contraception from maternity settings. Introduction of supportive PPC policies, funding and training for staff could improve outcomes for mothers and babies.

Purpose: To evaluate the impact of levonorgestrel-releasing intrauterine device (LNG-IUD) use on the incidence of acne in adolescents and young women.

Methods: A narrative review was conducted in PubMed, Embase, Cochrane, and SciELO assessing the incidence of acne in adolescents and young women using LNG-IUD (13.5, or 19.5 mg, or 52 mg). Cohort, cross-sectional studies, clinical trials, and meta-analyses were included, without a date limit. Studies that didn't evaluate women in the age of interest were excluded. Only articles in English were selected.

Results: Nine articles were included in this narrative review. Only clinical trials, cohort studies, and cross-sectional studies were evaluated. Two cross-sectional studies evaluated the incidence of acne in women using any contraceptive methods, with the incidence of acne being 36% in women aged 17 to 47 using LNG-IUD in one study. In another study, acne incidence ranged from 2 to 8% in women using any contraceptive methods, with higher rates in younger women and LNG-IUD users. The incidence of acne varies and participants between 16 to 35 years were more likely to report new acne or worsening of pre-existing acne. In a prospective cohort study of women between 16 and 24 years, acne was a common adverse effect, with 44% in the first year.

Conclusion: The data indicate variability in the incidence of acne among LNG-IUD users, with a higher prevalence observed in younger women. Further research should focus on the effects of LNG-IUD on acne in young populations, with rigorous study designs and consideration of previous contraceptive use.

Background: Emergency contraception reduces the risk of unintended pregnancy, after unprotected sexual intercourse or contraceptive failure. In Belgium, emergency contraception is available without a prescription and pharmacists play therefore a crucial role in dispensing emergency contraception.

Aim: This study assesses the dispensing practices of emergency contraception by pharmacists in two regions of Belgium.

Method and design: Simulated patient study, using a predefined scenario, evaluating a request for emergency contraception. The scenario involves a 25-year-old woman not using contraception, who had unprotected sexual intercourse 84 h (3.5 days) ago. Her last menstrual period was 10 days ago.

Population: 260 pharmacies were randomly selected. Principal outcome: proportion of pharmacists who deliver the adequate emergency contraception. We considered the following responses as adequate: Prescribing ulipristal acetate or redirecting to another pharmacy, in case of unavailability, or referring for a copper IUD.

Results: We analysed the data obtained in 216 pharmacies (216/260 = 83.1%). In 64% of cases, adequate dispensing of emergency contraception (dispensing of ulipristal acetate or referral for intrauterine device insertion) occurred. There was an association between correct dispensing and asking appropriate questions, such as the date of the last menstrual period and the date of the risky sexual intercourse.

Conclusion: More than one-third of visited pharmacies did not distribute appropriate emergency contraception, underlining the need for improvement. We hypothesise that this may be achieved with appropriate training, use a dispensing checklist.

Objective: Human Chorionic Gonadotropin (hCG) plays a crucial role in embryo implantation and in maintenance of pregnancy. An immuno-contraceptive approach involves the use of a recombinant hCGβ-LTB vaccine formulated with adjuvant Mycobacterium indicus pranii (MIP), to prevent pregnancy without disturbing ovulation, hormonal profiles, and menstrual cycles in women. The present work in mice was designed to address issues encountered in clinical trials conducted with hCGβ-LTB vaccine, with focus on two primary concerns. Firstly, it aimed to determine the optimal vaccine dosage required to induce a high level of anti-hCG antibodies. Secondly, it aimed to assess the safety profile of the vaccine, specifically injection site reactions in the form of nodules, observed in some of the subjects.

Methods and results: Studies undertaken indicate that a 2 µg dose of the protein version of the vaccine, administered in mice through the intramuscular route, can induce high anti-hCG titres. Furthermore, administering a booster dose enhances the antibody response. Our findings suggest that the concentration and frequency of administration of the adjuvant MIP can also be reduced without compromising vaccine efficacy.

Conclusion: The issue of nodule formation at the injection site can be mitigated either by administering the vaccine along with MIP intramuscularly or injecting hCG vaccine and MIP at separate intradermal sites. Thus, protein vaccine administered at a 2µg dose via the intramuscular route addresses both efficacy and safety concerns.

Objective: To evaluate the influence of the personal experience of female obstetricians and gynaecologists (Obst/Gyns) who utilise contraceptive methods on the provision of these methods.

Methods: An anonymous online web-based survey was carried out with female Obst/Gyns. The instrument contained questions about their current and previous contraceptive methods use, factors that influenced the choice and satisfaction with the ongoing method, as well as the occurrence of adverse events. They were also asked whether the experience of any adverse events influenced their decision in prescribing any particular contraceptive method.

Results: 476/9000 (5.3%) female Obst/Gyns answered the survey. The most common contraceptive in use was the 52-mg levonorgestrel-intrauterine device (52-mg LNG-IUD) (34%), followed by non-Long-Acting Reversible Contraception hormonal methods (21.2%). More than half of the respondents (57.6%) reported having some adverse effects and 18.7% reported that the personal experience of an adverse effect with the use of a contraceptive method influenced the prescription of that method.

Conclusion: Half of female Obst/Gyns encountered adverse events linked to contraceptive usage. Additionally, almost one-fifth believe that their own encounter with adverse effects from a contraceptive method impacts their decision to prescribe the same method.
