Contraception and reproductive medicine最新文献

In this commentary, we examine the evolution of theories and metrics regarding contraception. We contend that while human rights principles are now widely integrated into the "supply-side factors" of contraceptive provision, particularly through the concept of quality of care and its metrics, their role in relation to "demand-side factors" remains ambiguous. We propose that human rights represent one of several normative frameworks to which both users and non-users may adhere when shaping their fertility preferences and decisions regarding contraception. To gain a deeper understanding of persistent obstacles on the demand side of contraceptive utilization, comprehensive data on attitudes toward sexuality and motherhood at both individual and community levels, as well as nuanced indicators of knowledge and acceptance of contraception among all women, are essential. Such data could facilitate examination of how exposure to human rights-based sexual and reproductive health programs influences normative contexts, individual empowerment among women, and the demand for contraception. Additionally, further research is needed to explore the reciprocal relationship-how contraceptive use influences women's trajectories of empowerment-which requires longitudinal data covering the entire reproductive lifespan.

Introduction: Cambodia is a low-income country with limited access to family planning (FP) in terms of modern contraceptive utilization. Despite several FP programs designed to make contraceptives accessible, adoption of contraceptives has been difficult in Cambodia, which has high rates of fertility and maternal mortality. This gap in essential care can put women and adolescent girls at greater risk of adverse outcomes such as stillbirth, spontaneous abortion, unwanted pregnancy, or even maternal death. One of the goals set by the government to decrease both maternal and child mortality and morbidity was increasing the modern contraceptives utilization. So, the main objective of this study was to evaluate spatial variations in modern contraceptives utilization and its contributing factors among women.

Methods: Data from the Cambodia 2021-22 Demographic and Health Survey datasets were used for secondary data analysis. A total of 19,496 women of reproductive age participated in the study. A spatial and multilevel mixed effects analysis was done on the factors affecting modern contraceptives utilization among Cambodian women. Finally, the percentage, odd ratio, together with their 95% confidence intervals and the results of the spatial analysis were provided.

Result: The prevalence of modern contraceptive use was 31.2% in Cambodia. Living in an urban area [AOR = 1.224; 95% CI = (1.126.1.330); P = 0.0001]; being married [AOR = 34.131; 95% CI= (12.673, 91.921); P = 0.0001]; and having a history of terminated pregnancy [AOR = 1.137; 95% CI= (1.055, 1.225); P = 0.0001] were found to be positively associated with modern contraceptive utilization. In contrast to this, being between the age range of 46-49 [AOR = 0.421; 95% CI = (0.364, 0.487); P = 0.0001]; being a female-headed household [AOR = 0.784; 95% CI = (0.723, 0.850); P = 0.0001]; and current breast feeding [AOR = 0.84; 95% CI = (0.75, 0.93); P = 0.010] were found to be negatively associated with modern contraceptive utilization. Additionally, the spatial analysis of modern contraceptive utilization showed that a higher proportion was utilized in the southern and southwest regions of Cambodia.

Conclusion: In this study, living in urban area, being married and having history of terminated pregnancy were found positively associated with modern contraceptive utilization. In contrast to this, being old age, being female headed household and being currently breast-feeding women were found negatively associated with modern contraceptive utilization. In addition to this, there were geographic (spatial) variations in modern contraceptive utilization among Cambodian's women across the country.

Introduction: In Uganda, although most women wish to delay or prevent future pregnancies, uptake of postpartum family planning (PPFP) is low. We explored behavioural factors influencing the utilisation of postpartum long-acting reversible contraceptives (LARCs) in Eastern Uganda.

Methods: We conducted a qualitative study in two districts of Eastern Uganda. We conducted 20 in-depth interviews and three focus group discussions with postpartum women, male partners, midwives, and village health team members. We analysed transcripts using framework analysis, based on the COM-B framework.

Results: The use of immediate postpartum LARC was affected by the capabilities of women in terms of their knowledge and misconceptions. Limited capabilities of health workers to provide counselling and insert IUDs, as well as shortages of implants, reduced the physical opportunites for women to access PPFP. Social opportunities for women were limited because men wanted to be involved in the decision but rarely had time to accompany their partners to health facilities, and health workers often appeared too stressed. Men also feared that PPFP would enable their partners to be unfaithful. Motivation to take up immediate postpartum LARC included the desire to space births, preference for contraceptive implants over intra uterine devices (IUD) at the 6-week postpartum period, resumption of sex and menses, partner support, and perceived effectiveness of postpartum contraception. Participants thought that uptake of immediate postpartum LARC could be improved by health education and outreach visits, male involvement and couples' counselling in antenatal clinic appointments, and enabling switching between family planning methods (in case of side-effects) .

Conclusion: Low uptake of PPFP was caused by inadequate knowledge and misconceptions about LARC by women and their partners, insufficient numbers of midwives trained to provide PPFP, stock-outs of PPFP methods, and few social opportunities for couples to be counselled together. These factors could be addressed by scaling up effective, low cost and innovative ways to provide health education (such as films), involving men in decision-making, as well as training more midwives to provide PPFP services, and ensuring that they have sufficient time and supplies.

Objective: This study aimed to assess the effect of sildenafil citrate and estradiol valerate as adjuvant therapy during ovarian stimulation cycles with clomiphene citrate in patients with unexplained infertility in Kisangani.

Method: A double-blind, randomized controlled trial was conducted for two years at two specialized health facilities in Kisangani (University Clinics of Kisangani and "Clinique des Anges Kisangani"). The population included 148 patients, 74 of whom were on clomiphene citrate + sildenafil citrate (CCSC) regimens and 74 of whom were on clomiphene citrate + estradiol valerate (CCEV) regimens for three months. The primary indicator was the conception rate, with secondary outcomes encompassing endometrial thickness, appearance and vascularity, the number of mature follicles and ovulation rate.

Results: The two groups were comparable in terms of sociodemographic and clinical characteristics. The mean duration of attempting to conceive was 4.39 years versus 4.36 years (P = 0.839), while the mean AFC was 11.51 versus 11.46 (P = 0.831), in the CCSC group versus CCEV group respectively. Secondary infertility was the most frequent diagnosis in each of the two groups. The biochemical pregnancy rate was comparable between the two groups (P = 0.385), while the clinical pregnancy rate was significantly higher in the CCSC group versus CCEV group (P = 0.04). Both perifollicular flow and the ovulation rate were significantly higher in the CCSC group versus the CCEV group (P = 0.006 and P = 0.002 respectively). However, endometrial vascularity/thickness, and the number of Graafian follicles were not significantly different between the two groups.

Conclusion: As an adjuvant, sildenafil increases the rate of clinical pregnancy more than does estradiol in patients with unexplained infertility undergoing ovarian stimulation with clomiphene citrate.

Background: Worldwide, sexual and reproductive health remains a prominent public health concern for women of reproductive age. Modern contraceptive methods play a crucial role in enabling individuals and families to regulate fertility, thereby reducing unintended pregnancies, abortions, pregnancy-related complications, and mortality. Due to the scarcity of reliable and current data regarding the factors affecting the adoption of modern contraceptives among women of reproductive age at the national level in Ghana, this research aimed to explore the determinants of modern contraceptive usage among reproductive age women.

Methods: The study analyzed data from the 2022 Ghana Demographic and Health Survey, including a weighted sample of 6,839 reproductive-age women. By employing a multilevel logistic regression model, the study sought to determine factors associated with the utilization of modern contraceptives. Associations between explanatory variables and the outcome were evaluated using adjusted odds ratios (AORs) along with 95% confidence intervals (CIs). Statistical significance was established using a p-value threshold of less than 0.05. All statistical analyses were conducted using STATA version 17 software.

Results: The study found that 26.36% (95% CI: 25.33-27.34%) of women of reproductive age in Ghana used modern contraceptives. Secondary education (AOR = 1.26, 95% CI = 1.03-1.53), poorer household (AOR = 1.30, 95% CI = 1.05-1.61), women's marital status, i.e. married (AOR = 1.46, 95% CI = 1.16-1.83), living with a partner (AOR = 1.65, 95% CI = 1.32-2.06), divorced (AOR = 2.53, 95% CI = 1.48-4.31), and separated (AOR = 1.70, 95% CI = 1.21-2.37), multipara (AOR = 1.39, 95% CI = 1.04-1.87), were the factors that promote modern contraceptive utilization. Women's age in years, i.e. 35-39 (AOR = 0.71, 95% CI = 0.52-0.97), 40-44 (AOR = 0.63, 95% CI = 0.44-0.90), and 45-49 (AOR = 0.45, 95% CI = 0.25-0.79), history of pregnancy loss (AOR = 0.86, 95% CI = 0.76-0.98), region, i.e. Greater Accra (95% CI = 0.42-0.92), Bono East (95% CI = 0.32-0.81), Northern (95% CI = 0.28-0.67), Savannah (95% CI = 0.28-0.81), and North East (95% CI = 0.20-0.63), were all associated with a lower use of modern contraceptives.

Conclusions: Modern contraceptive utilization was low in this study. Factors such as women's education, socioeconomic status, and marital status were associated with increased modern contraceptive utilization, whereas women's age and regional disparities were linked to lower usage rates. These findings emphasize the need for targeted interventions to address socioeconomic barriers and regional disparities in access to family planning services across Ghana.

Background: This study examines the likelihood of contraceptive use among married women in sub-Saharan Africa, focusing on the influence of spousal age difference.

Methods: Binary logistic regressions predicting contraceptive use were estimated using a sample of 478,193 women in first union from 29 sub-Saharan African countries spanning two decades from 1999 to 2022. The data were sourced from the Demographic and Health Surveys (DHS).

Results: The regression results indicate that spousal age difference is negatively correlated with the likelihood of contraceptive use with each additional year reducing the odds of using contraception by 1.1 percent. The association between the two variables has remained largely consistent over time. The findings also show substantial variation in the influence of spousal age differences on contraceptive use ranging from statistically significant and negative odds in some countries to not statistically significant but positive odds in others. Measures of female autonomy, education and healthcare decision-making, had a modest influence on the size and significance of the association between spousal age difference and contraceptive use.

Conclusions: The relationship between spousal age difference and contraceptive use is of concern given the prevalence of age-disparate relationships in the context. These findings add to the literature on the potentially negative implications of age-disparate relationships, while highlighting that the association is not uniformly negative across countries.

Background: Adenomyosis can lead to infertility and failure of in vitro fertilization. Limited evidence suggests that the use of long-term treatment with gonadotropin-releasing hormone (GnRH) agonists followed by frozen-thawed embryo transfer (FET) may be the preferred approach for women with adenomyosis.

Objective: The aim of this randomized controlled trial is to compare the efficacy of an ultra-long GnRH agonist with standard downregulation in women with adenomyosis undergoing FET.

Materials and methods: This randomized controlled trial enrolled 72 women with adenomyosis diagnosed by sonographic criteria who underwent FET cycles at the Avicenna Infertility Center. These women were randomly assigned to two equal groups: one received GnRH agonist treatment for three months before the FET cycle and the other served as the standard downregulation group. Results were reported as chemical and clinical pregnancy rates.

Results: The two groups were similar in age, body mass index, anti-Müllerian hormone levels, number of previous pregnancies and miscarriages, presence of uterine myomas, and endometriosis. However, the total dose of estradiol used until embryo transfer was significantly higher in the ultra-long GnRH agonist group than in the standard group (96.14 mg vs. 80.52 mg, p-value = 0.004). Nevertheless, chemical and clinical pregnancy rates did not differ significantly between the two groups.

Conclusions: Ultra-long GnRH agonist downregulation did not improve the chemical and clinical pregnancy rate in the FET cycle in women with adenomyosis compared with standard GnRH agonist downregulation in the other words, ultra-long GnRH agonist downregulation is not superior to standard protocol. In women with adenomyosis (without history of endometriosis), downregulation of standard GnRH agonists prior to frozen-thawed embryo transfer may be the preferred embryo transfer protocol to gain higher clinical/chemical pregnancy rate.

Background: Women's intentions to use any contraceptive method are critical for better understanding their future needs and making them more likely to act on that intention. This study assessed the factors associated with the intention to use modern contraceptives among women of reproductive age in Benin.

Methods: This was a cross-sectional study that used the 2017-2018 Benin Demographic and Health Survey (BDHS). The study analyzed a weighted sample of 13, 582 women of reproductive age who were non-users of contraceptives. The intention to use contraceptives was the outcome variable. Multivariate logistic regression analysis was conducted to determine the factors associated with the intention to use contraceptives among women of reproductive age. The results were estimated using an adjusted odds ratios (aOR) with a 95% confidence interval (CI) and statistical significance set at p < 0.05.  RESULTS: Approximately 35.0% of the women had the intention to use modern contraception. We found that women aged between 30 and 34 (aOR = 0.70, 95%CI: 0.57, 0.86), 35-39 (aOR = 0.52, 95%CI: 0.42, 0.66), 40-44(aOR = 0.30, 95%CI: 0.22, 0.39) and 45-49 (aOR = 0.10, 95%CI: 0.07, 0.14), Muslim women (aOR = 0.68, 95%CI: 0.53, 0.85) and those who perceived the distance to a health facility not to be a big problem (aOR = 0.75, 95%CI: 0.67, 0.84) were less likely to have the intention to use modern contraceptives compared with their counterparts. On the other hand, women who attained primary (aOR = 1.21, 95%CI: 1.07, 1.36), secondary (aOR = 1.39, 95%CI: 1.21, 1.59), and higher education (aOR = 1.60, 95%CI: 1.13, 2.26), women who were employed (aOR = 1.39, 95%CI: 1.23, 1.57), women with no religion (aOR = 1.32, 95%CI: 1.04, 1.69), women whose partners were working (aOR = 1.69, 95%CI: 1.16, 2.44), women who heard about family planning in the media (aOR = 1.51, 95%CI: 1.16, 2.44), and women in the poorer (aOR = 1.31, 95%CI: 1.10, 1.54), middle (aOR = 1.42, 95%CI: 1.20, 1.67]), richer (aOR = 1.23, 95%CI: 1.03, 1.47), and richest households (aOR = 1.42, 95%CI: 1.15, 1.75) were more likely to have the intention to use contraceptives than their counterparts.

Conclusion: The study provides valuable insights into the intention to use contraceptives among women of reproductive age in Benin. The findings indicate that the proportion of women who have intention to use contraceptives remains low. The findings of this study could inform the development of targeted interventions and policies to increase access to and uptake of contraceptives in Benin, with the ultimate aim of improving the reproductive health and well-being of women and their families.

Background: We report a rare and unusual case of intravesical migration of an intrauterine device with stone formation. The intrauterine device (IUD) is the most common method of reversible contraception in women. However, its insertion is not without risk, it can cause early or late complications. IUD can perforate the uterus wall and migrate into adjacent structures.

Case presentation: A 35 year-old female 5 gravid, 4 para has been benefited from intrauterine contraceptive device (IUCD) 5 years ago, she was presented to gynecological consultation for chronic pelvic pain with urinary symptoms. There was history of a good IUD insertion 5 years ago, considered expelled after one month of its pose. Physical examination was normal, but a pelvic ultrasound and a plain abdominal radiography allowed the detection of an IUD outside the uterine cavity, but inside bladder. A diagnostic and therapeutic cystoscopy was performed, and the IUD with calculus was successfully removed. There were no postoperative complications.

Conclusion: This case is reported to highlight and to reiterate the need to think about one of the rare complication of IUD insertion, which every practitioner must know, it's the transuterovesical migration, before concluding wrongly to its expulsion. It's a consequence of, non-compliance with the rules for inserting an IUD and poor monitoring. The evolution towards calcification is a certain consequence; its screening involves rigorous clinical monitoring.
