Permanent Contraception for Women

Nanomaterials Solutions for Contraception: Concerns, Advances, and Prospects

Preventing unintentional pregnancy is one of the goals of a global public health policy to minimize effects on individuals, families, and society. Various contraceptive formulations with high effectiveness and acceptance, including intrauterine devices, hormonal patches for females, and condoms and vasectomy for males, have been developed and adopted over the last decades. However, distinct breakthroughs of contraceptive techniques have not yet been achieved, while the associated long-term adverse effects are insurmountable, such as endocrine system disorder along with hormone administration, invasive ligation, and slowly restored fertility after removal of intrauterine devices. Spurred by developments of nanomaterials and bionanotechnologies, advanced contraceptives could be fulfilled via nanomaterial solutions with much safer and more controllable and effective approaches to meet various and specific needs for women and men at different reproductive stages. Nanomedicine techniques have been extended to develop contraceptive methods, such as the targeted drug delivery and controlled release of hormone using nanocarriers for females and physical stimulation assisted vasectomy using functional nanomaterials via photothermal treatment or magnetic hyperthermia for males. Nanomaterial solutions for advanced contraceptives offer significantly improved biosafety, noninvasive administration, and controllable reversibility. This review summarizes the nanomaterial solutions to female and male contraceptives including the working mechanisms, clinical concerns, and their merits and demerits. This work also reviewed the nanomaterials that have been adopted in contraceptive applications. In addition, we further discuss safety considerations and future perspectives of nanomaterials in nanostrategy development for next-generation contraceptives. We expect that nanomaterials would potentially replace conventional materials for contraception in the near future.

The role of female permanent contraception in meeting the demand for family planning in low- and middle-income countries

OBJECTIVE

Our aim was to describe the reliance on female permanent contraception among women with demand for family planning satisfied with modern methods (mDFPS) in low- and middle-income countries (LMICs) and to describe socio-economic and demographic patterns of permanent contraception in countries with high use.

METHODS

Using data from the latest national health survey carried out in LMICs we estimated mDFPS and the share of each contraceptive method used. Countries with a share of more than 25% of female permanent contraception were further explored for differences by wealth, number of living children, woman's age, and by the intersection of woman's age and number of living children.

RESULTS

In the 20 countries studied, between 6% and 94% of the contracepting population used modern methods. Female permanent contraception accounted for more than half of women using modern contraceptives in India, Dominican Republic, El Salvador, Mexico, and Colombia. In India and Tonga, more than 20% of women using contraceptives with fewer than two living children were using female permanent contraception. Among women with two living children, countries with the highest reliance on permanent contraception were India (79%), El Salvador (61%), Cuba (55%), Colombia (52%), and Thailand (51%). Dominican Republic, El Salvador, India, and Mexico presented high levels of permanent contraception among younger women, with reliance higher than 30% among women aged 25 to 29 and 50% or more among women aged 30 to 34.

CONCLUSIONS

Reliance on permanent contraception was high in several countries and among women aged less than 35 years.

Determinants of female sterilization method uptake among women of reproductive age group in Uganda

Background

Despite its great effectiveness, safety and convenience for women who do not wish to have more children; female sterilization method uptake in Uganda is very low. This study aimed at establishing factors associated with female sterilization uptake in Uganda.

Methods

Secondary data were sourced from the 2016 Uganda Demographic and Health Survey (UDHS). We analyzed all (18,506) women aged 15–49 years who were interviewed in the 2016 UDHS. This sample was categorized into women who were sterilized and those using other modern methods. We used a Chi-square test to measure the association between the current uptake of female sterilization by the women and selected independent variables. Multivariate analysis applied the complimentary log-log model to determine the net effect of selected characteristics on female sterilization uptake in Uganda.

Results

The overall prevalence of female sterilization among modern contraceptive users was 2%. Female sterilization uptake was highly associated with age of 30 years and older (OR = 34.49;, 95%CI:13.33–99.88), middle wealth status (OR = 0.65, 95% CI:0.47–0.92), women who had ever given birth to at least four children (OR = 3.19, 95% CI:1.63–6.22) and decision making by either the husband/partner (OR = 2.42, 95% CI:1.55–3.78) or jointly between a woman and her husband/partner (OR = 1.38, 95% CI:1.02–1.86).

Conclusions

The uptake of female sterilization was very low, and this was associated with; age, household wealth, parity and contraceptive decision-maker. The uptake of Family planning programs needs to focus on male engagement to increase joint decision making on family planning issues especially those relating to fertility limitation. Government and its other implementing partners need to scale-up efforts that increase accessibility to information on female sterilization services for women who have completed their fertility.

Management of pregestational diabetes mellitus: a comparison of guidelines

Background: Pregestational diabetes is associated with adverse maternal and neonatal outcomes. The aim of this study was to summarize and compare evidence-based recommendations on pregestational diabetes and to focus especially on issues related to the management of this entity.Materials and methods: A descriptive review of three recently published national guidelines on pregestational diabetes was conducted: the American Diabetes Association on "Diabetes in Pregnancy: Standards of Medical Care in Diabetes - 2019," the National Institute for Health and Care Excellence on "Diabetes in pregnancy: management from preconception to the postnatal period" and the American College of Obstetricians and Gynecologists on "Pregestational Diabetes Mellitus." These guidelines were compared according to recommendations on management, during the preconception, antenatal, intrapartum and postpartum period.Results: There were many similar recommendations regarding the preconception counseling, the antepartum assessment by specialists, the glycemic control target levels, the pharmacologic treatment and the postpartum period among the three guidelines. On the other hand, the American Diabetes Association makes no recommendations regarding fetal monitoring and obstetric management during pregnancy and the intrapartum period, while there are several similarities between the other two guidelines.Conclusions: The adoption of an international consensus based on evidence - based guidelines will increase the awareness of the healthcare professionals on the management of pregestational diabetes, leading that way to more favorable perinatal outcomes.

Uptake of permanent contraception among women in sub-Saharan Africa: a literature review of barriers and facilitators

OBJECTIVE

Uptake of permanent contraception among women remains low in sub-Saharan Africa compared to other regions. We aimed to synthesize available evidence on barriers to, and facilitators of permanent contraception with regards to tubal ligation among women in sub-Saharan Africa.

STUDY DESIGN

We reviewed literature on tubal ligation among African women published between January 1, 2000 and October 30, 2017. We searched PubMed, Global health, EMBASE, Web of science, and Google scholar for quantitative, qualitative, and mixed methods studies which reported on barriers and/or facilitators to uptake of tubal ligation in sub-Saharan Africa. Finally, we conducted a narrative synthesis and categorized our findings using a framework based on the social ecological model.

RESULTS

We included 48 articles in the review. Identified barriers to tubal ligation among women included individual-level (myths and misconceptions, fear of surgery, irreversibility of procedure, religious beliefs), interpersonal-level (male partner disapproval), and organizational-level (lack of healthcare worker expertise and equipment) factors. Facilitating factors included achievement of desired family size and perceived effectiveness (individual-level), supportive male partners and knowing other women with permanent contraception experience (interpersonal-level), and finally, subsidized cost of the procedure and task-sharing with lower cadre healthcare workers (organizational-level).

CONCLUSIONS

Barriers to, and facilitators of permanent contraception among women in sub-Saharan Africa are multilevel in nature. Strategies countering these barriers should be prioritized, as effective contraception can promote women's health and economic development in sub-Saharan Africa. In addition to these strategies, more quantitative research is needed to further understand patient-level factors associated with uptake of permanent contraception among women.

Evaluation of Influencing Factors on Tubal Sterilization Regret: A Cross-Sectional Study

BACHGROUND

The aim of this study is to evaluate the menstrual pattern, sexual function, and anxiety, and depression in women with poststerilization regret, and potential influencing factors for regret following tubal ligation (TL) in Iranian women.

MATERIALS AND METHODS

In this cross-sectional study, 166 women with TL were subdivided into two groups including women with poststerilization regret (n=41) and women without poststerilization regret (n=125). They were selected from a health care center in Guilan province (Iran) during 2015-2016. Menstrual blood loss was measured using the Pictorial Blood Loss Assessment Chart (PBLAC) and through a self-administered questionnaire. In addition, sexual function was assessed by the Female Sexual Function Index (FSFI), and psychological distress was measured by employing the Hospital Anxiety and Depression Scale (HADS). Student's t test and Chi-square test were used to reveal the statistical differences between the two groups. We used logistic regression to determine the influencing factors associated with regretting sterilization.

RESULTS

Women with poststerilization regret had more menorrhagia (78 vs. 57.6%, P=0.03) than those who did not regret sterilization. A significant difference was found in sexual dysfunction in orgasm (P=0.02), satisfaction (P=0.004), pain (P=0.02), and total FSFI scores (P=0.007) between the two groups. Also, there was a significant difference between the two groups in anxiety, depression and total scores HADS (P=0.01). In the logistic regression model, age of sterilization [odds ratio (OR=2.67), confidence interval (CI): 1.03-7.81, P=0.04)], pre-sterilization counseling (OR=19.92, CI: 6.61-59.99, P<0.001), score of PBLAC (OR=1.01, CI: 1.004-1.01, P=0.001), the number of days of bleeding (OR=1.37, CI: 1.01-1.99, P=0.04), and the length of menstrual cycles (OR=0.91, CI: 0.84-0.99, P=0.03) were significantly associated with regretting sterilization.

CONCLUSION

Complications due to sterilization are the main causes of regret; therefore, it is necessary to pay due attention to mentioning the probable complications of the procedures such as menstruation disorders, sexual dysfunction, and anxiety and depression in women during pre-sterilization counseling.
