Skin patch and vaginal ring versus combined oral contraceptives for contraception

Contraception

Contraception counseling and provision are vital components of comprehensive health care. An unplanned pregnancy can be particularly challenging for patients with chronic illness. Internal medicine physicians are uniquely positioned to assess pregnancy readiness and provide contraception, as they often intersect with pregnancy-capable patients at the moment of a new diagnosis or when providing ongoing care for a chronic medical condition. A shared decision-making counseling approach engages patients, ensures patient-centered care, and supports their choice of a contraceptive method that aligns with their reproductive plans and medical needs.

Women's health, hormonal balance, and personal autonomy

Hormone-based contraception disrupts hormonal balance, creating artificial states of anovulation and threatening women's health. We reviewed its main adverse effects and mechanisms on accelerated ovarian aging, mental health (emotional disruptions, depression, and suicide), sexuality (reduced libido), cardiovascular (brain stroke, myocardial infarction, hypertension, and thrombosis), and oncological (breast, cervical, and endometrial cancers). Other "collateral damage" includes negative effects on communication, scientific mistrust, poor physician-patient relationships, increased patient burden, economic drain on the healthcare system, and environmental pollution. Hormone-sensitive tumors present a dilemma owing to their potential dual effects: preventing some cancers vs. higher risk for others remains controversial, with denial or dismissal as non-relevant adverse effects, information avoidance, and modification of scientific criteria. This lack of clinical assessment poses challenges to women's health and their right to autonomy. Overcoming these challenges requires an anthropological integration of sexuality, as the focus on genital bodily union alone fails to encompass the intimate relational expression of individuals, complete sexual satisfaction, and the intertwined feelings of trust, safety, tenderness, and endorsement of women's femininity.

Knowledge on, Attitude Toward, and Practice of Contraceptive Methods Among Females of Reproductive Age in Al-Qunfudah Governorate, Saudi Arabia

Background One of the main goals of Vision 2030 in Saudi Arabia is to increase the participation rate of Saudi females in the workforce. This adjustment may have a big impact on how they use contraception and increase the tendency to space out their children's births appropriately to help them balance their home and work lives. The purpose of this study was to assess the knowledge on, attitude toward, and practice of contraceptive methods among females of reproductive age (15-49 years) in Al-Qunfudah governorate, Saudi Arabia. Methods A cross-sectional study was carried out among a convenient sample of 400 females of reproductive age in Al-Qunfudah governorate, Saudi Arabia. The necessary data were obtained over a period of two months (from November to December 2022) by using a self-administered online survey that was applied on different electronic platforms. Both knowledge and attitude scores were divided into two categories using the median as a cutoff point (e.g., good knowledge and poor knowledge, as well as positive and negative attitude). Many sociodemographic variables, such as age, residence, and education, were independent variables. Logistic regression analysis was done to determine the magnitude of associations between independent and dependent variables, and the odds ratios (OR) were presented with 95% confidence intervals (CI) at a significance level of P = 0.05. Results Good knowledge of the different contraceptive methods was observed among 69.8% of the females, where contraceptive pills and the intrauterine device (IUD) were the most well-known contraceptive methods to them (85.25% and 57.75%, respectively). Family and friends were their main sources of information (38.75%). Almost 85% of the participants showed a positive attitude toward contraceptive use. Contraceptive pills (32.39%) and IUDs (29.95%) were the most commonly used contraceptive methods. The determinants of good knowledge of contraception were being younger in age (P = 0.01, OR = 0.14, 95% CI = 0.03-0.65) and living in an urban area (P = 0.01, OR = 0.24, 95% CI = 0.09-0.68). Females holding middle or high school educational degrees (P = 0.02, OR = 0.17, 95% CI = 0.04-0.75 and P = 0.03, OR = 0.23, 95% CI = 0.06-0.88, respectively) and having a low monthly income (P = 0.04, OR = 0.44, 95% CI = 0.20-0.96) were likely to have positive attitudes toward contraceptive methods. Conclusion This study concludes that females of reproductive age had satisfactory knowledge and a positive attitude toward various contraceptives; however, there is a big gap in their knowledge regarding two important contraceptive procedures (emergency and permanent contraceptives). Oral contraceptive (OC) pills and IUDs were the most utilized methods of contraception among them. Sustained efforts are needed to raise females' awareness about contraception methods, especially emergency contraceptives and permanent ones. This study was done on a convenient sample of females in reproductive age that may limit the generalization of data; using an online survey has its constraints, such as the ignorance of the illiterate females and those who did not possess internet connections in addition to recall bias; therefore, we recommend further research on this topic through an interactive interview among a random sample of females to overcome such pitfalls.

Contraception During Perimenopause: Practical Guidance

Climacteric is by no means in itself a contraindication to safe contraception. On the contrary, there are several conditions related to the perimenopause that could benefit from the use of modern contraceptives, mainly hormonal, with the goals of avoiding unintended pregnancies and giving further possible benefits beyond contraception (menstrual cycle control, a reduction of vasomotor symptoms and menstrual migraines, a protection against bone loss, a positive oncological risk/benefit balance). This narrative review aims to provide practical guidance on their possible use in this particular life stage, both short- and long-acting reversible contraceptives, and to assist clinicians for women transitioning from contraception to their menopausal years, including the possible initiation of postmenopausal hormone therapy. Comprehensive contraceptive counselling is an essential aspect of the overall health and wellbeing of women and should be addressed with each such patient irrespective of age.

An endocrine perspective on menstrual suppression for adolescents: achieving good suppression while optimizing bone health

Suppression of menstruation and/or ovarian function in adolescent girls may be desired for a variety of reasons. Numerous medical options exist. The choice of the appropriate modality for an individual patient depends on several factors based on differences in the efficacy of achieving menstrual suppression as well as in their side effect profiles. Adolescence is also a period of bone mass accrual in girls, and several of these modalities may negatively influence peak bone mass. This review focuses on the efficacy of achieving menstrual suppression and the effect on bone health of the various options through an overview of the current literature and also highlights areas in need of further research.

Vaginal Administration of Contraceptives

While contraceptive drugs have enabled many people to decide when they want to have a baby, more than 100 million unintended pregnancies each year in the world may indicate the contraceptive requirement of many people has not been well addressed yet. The vagina is a well-established and practical route for the delivery of various pharmacological molecules, including contraceptives. This review aims to present an overview of different contraceptive methods focusing on the vaginal route of delivery for contraceptives, including current developments, discussing the potentials and limitations of the modern methods, designs, and how well each method performs for delivering the contraceptives and preventing pregnancy.

Contraception in chronic kidney disease: a best practice position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology

Even though fertility is reduced, conception and delivery are possible in all stages of CKD. While successful planned pregnancies are increasing, an unwanted pregnancy may have long-lasting deleterious effects, hence the importance of birth control, an issue often disregarded in clinical practice. The evidence summarized in this position statement is mainly derived from the overall population, or other patient categories, in the lack of guidelines specifically addressed to CKD. Oestroprogestagents can be used in early, non-proteinuric CKD, excluding SLE and immunologic disorders, at high risk of thromboembolism and hypertension. Conversely, progestin only is generally safe and its main side effect is intramestrual spotting. Non-medicated intrauterine devices are a good alternative; their use needs to be carefully evaluated in patients at a high risk of pelvic infection, even though the degree of risk remains controversial. Barrier methods, relatively efficacious when correctly used, have few risks, and condoms are the only contraceptives that protect against sexually transmitted diseases. Surgical sterilization is rarely used also because of the risks surgery involves; it is not definitely contraindicated, and may be considered in selected cases. Emergency contraception with high-dose progestins or intrauterine devices is not contraindicated but should be avoided whenever possible, even if far preferable to abortion. Surgical abortion is invasive, but experience with medical abortion in CKD is still limited, especially in the late stages of the disease. In summary, personalized contraception is feasible, safe and should be offered to all CKD women of childbearing age who do not want to get pregnant.

Effects of Hormonal Contraceptives on Mood: A Focus on Emotion Recognition and Reactivity, Reward Processing, and Stress Response

PURPOSE OF REVIEW

We review recent research investigating the relationship of hormonal contraceptives and mood with a focus on relevant underlying mechanisms, such as emotion recognition and reactivity, reward processing, and stress response.

RECENT FINDINGS

Adverse effects of hormonal contraceptives (HCs) on mood seem most consistent in women with a history of depressive symptoms and/or previous negative experience with HC-intake. Current evidence supports a negativity bias in emotion recognition and reactivity in HC-users, although inconsistent to some extent. Some data, however, do indicate a trend towards a blunted reward response and a potential dysregulation of the stress response in some HC-users. HC-effects on psychological and neurophysiological mechanisms underlying mood are likely context-dependent. We provide suggestions on how to address some of the contributing factors to this variability in future studies, such as HC-dose, timing, administration-mode, and individual risk. A better understanding of how and when HCs affect mood is critical to provide adequate contraceptive choices to women worldwide.

Public health's social contract: An obstacle in the advancement of effective HIV technologies

Evidence from the past 40 years of HIV technology development and implementation indicates that the public health social contract - with its expectations of patient/citizen compliance - has hampered global disease control efforts. Despite the availability of a wide array of effective technologies, including antiretroviral drugs as treatment and prevention, voluntary medical male circumcision procedures, and newly developed intravaginal ring products, new infections among adults globally have not decreased significantly. In this paper, I describe a historical trend of limiting access to effective biomedical technologies to those deemed most deserving and compliant given concerns of misuse (non-adherence), product repurposing (not using the product for purposes originally intended), and the incitement of autonomy (increasing the risk of public exposure to diseases given personal protection from a specific disease). Examining the expectations of good citizenship (compliance, adherence, appropriate product use, and continued risk reduction) as it relates to human-technology interactions, reveals a continuing narrative of initially restricting access to newer technologies perceived fragile or costly based on an assessment of patient/citizen worth. In this, the conventional public health social contract continues to be an obstacle in the advancements of technologies to effectively reduce the global burden of HIV.

Randomized, placebo controlled phase I trial of safety, pharmacokinetics, pharmacodynamics and acceptability of tenofovir and tenofovir plus levonorgestrel vaginal rings in women

To prevent the global health burdens of human immunodeficiency virus [HIV] and unintended/mistimed pregnancies, we developed an intravaginal ring [IVR] that delivers tenofovir [TFV] at ~10mg/day alone or with levonorgestrel [LNG] at ~20μg/day for 90 days. We present safety, pharmacokinetics, pharmacodynamics, acceptability and drug release data in healthy women. CONRAD A13-128 was a randomized, placebo controlled phase I study. We screened 86 women; 51 were randomized to TFV, TFV/LNG or placebo IVR [2:2:1] and 50 completed all visits, using the IVR for approximately 15 days. We assessed safety by adverse events, colposcopy, vaginal microbiota, epithelial integrity, mucosal histology and immune cell numbers and phenotype, cervicovaginal [CV] cytokines and antimicrobial proteins and changes in systemic laboratory measurements, and LNG and TFV pharmacokinetics in multiple compartments. TFV pharmacodynamic activity was measured by evaluating CV fluid [CVF] and tissue for antiviral activity using in vitro models. LNG pharmacodynamic assessments were timed based on peak urinary luteinizing hormone levels. All IVRs were safe with no significant colposcopic, mucosal, immune and microbiota changes and were acceptable. Among TFV containing IVR users, median and mean CV aspirate TFV concentrations remained above 100,000 ng/mL 4 hours post IVR insertion and mean TFV-diphosphate [DP] concentrations in vaginal tissue remained above 1,000 fmol/mg even 3 days post IVR removal. CVF of women using TFV-containing IVRs completely inhibited [94-100%] HIV infection in vitro. TFV/LNG IVR users had mean serum LNG concentrations exceeding 300 pg/mL within 1 hour, remaining high throughout IVR use. All LNG IVR users had a cervical mucus Insler score <10 and the majority [95%] were anovulatory or had abnormal cervical mucus sperm penetration. Estimated in vivo TFV and LNG release rates were within expected ranges. All IVRs were safe with the active ones delivering sustained high concentrations of TFV locally. LNG caused changes in cervical mucus, sperm penetration, and ovulation compatible with contraceptive efficacy. The TFV and TFV/LNG rings are ready for expanded 90 day clinical testing.

Hormonal contraception increases the risk of psychotropic drug use in adolescent girls but not in adults: A pharmacoepidemiological study on 800 000 Swedish women

The burden of depression and anxiety disorders is greater in women, and female sex hormones have been shown to affect mood. Psychological side effects of hormonal contraception (HC) are also a common complaint in the clinic, but few previous studies have investigated this subject. We therefore wanted to investigate whether use of HC was associated with adverse psychological health outcomes, and whether this association was modified by age. All women aged 12–30 years on 31 December 2010, residing in Sweden for at least four years and with no previous psychiatric morbidity (n = 815 662), were included. We followed the women from their first HC use (or 31 December 2010, if they were non-users) at baseline, until a prescription fill of psychotropic drugs or the end of the one-year follow-up. We performed age-stratified logistic regression models and estimated odds ratios (OR) to measure the association between different HC methods and psychotropic drug use, as well as the area under the receiver operating curve to estimate discriminatory accuracy of HC in relation to psychotropic drugs. Overall, we found an association between HC and psychotropic drugs (adjusted OR 1.34, 95% confidence interval [CI] 1.30–1.37). In the age-stratified analysis, the strongest association was found in adolescent girls (adjusted OR 3.46, 95% CI 3.04–4.94 for age 12 to 14 years), while it was non-existent for adult women. We conclude that hormonal contraception is associated with psychotropic drug use among adolescent girls, suggesting an adverse effect of HC on psychological health in this population.

Pharmacologic Therapies in Women's Health: Contraception and Menopause Treatment

Female hormones play a significant role in the etiology and treatment of many women's health conditions. This article focuses on the common uses of hormonal therapy. When prescribing estrogen-containing regimens throughout the span of a woman's life, the risks are similar (ie, cardiovascular risk and venous thromboembolism), but the degree of risk varies significantly depending on a woman's particular set of risk factors and the details of the hormone regimen. In addition to estrogens and progestogens, this article also touches on the use of selective steroid receptor modulators in emergency contraception and in treatment of menopause symptoms.

The Promise of Intravaginal Rings for Prevention: User Perceptions of Biomechanical Properties and Implications for Prevention Product Development

Intravaginal rings (IVRs) are currently under investigation as devices for the delivery of agents to protect against the sexual transmission of HIV and STIs, as well as pregnancy. To assist product developers in creating highly acceptable rings, we sought to identify characteristics that intravaginal ring users consider when making decisions about ring use or non-use. We conducted four semi-structured focus groups with 21 women (aged 18-45) who reported using an IVR in the past 12 months. Participants manipulated four prototype rings in their hands, discussed ring materials, dimensionality, and "behavior," and shared perceptions and appraisals. Five salient ring characteristics were identified: 1) appearance of the rings' surfaces, 2) tactile sensations of the cylinder material, 3) materials properties, 4) diameter of the cylinder, and 5) ring circumference. Pliability (or flexibility) was generally considered the most important mechanical property. Several ring properties (e.g., porousness, dimensionality) were associated with perceptions of efficacy. Women also revealed user behaviors that may impact the effectiveness of certain drugs, such as removing, rinsing and re-inserting the ring while bathing, and removing the ring during sexual encounters. As product developers explore IVRs as prevention delivery systems, it is critical to balance product materials and dimensions with use parameters to optimize drug delivery and the user experience. It is also critical to consider how user behaviors (e.g., removing the ring) might impact drug delivery.

Observational, prospective, multicentre study to evaluate the effects of counselling on the choice of combined hormonal contraceptives in Italy--the ECOS (Educational COunselling effectS) study

BACKGROUND

Adequate counselling on contraceptive methods can help users choose the most appropriate method. The aim of this study was to assess the effects of structured counselling provided by gynaecologists on selection of a combined hormonal contraception method.

METHODS

Women aged 18-40 years (n = 1871) who were considering the use of a combined hormonal contraception method (pill, transdermal patch or vaginal ring) underwent a structured counselling session in which gynaecologists provided comprehensive information. Pre- and post-counselling questionnaires on combined hormonal contraception choice were completed by participants.

RESULTS

After counselling, many women (38 %) selected a combined hormonal contraception method that was different from the originally intended one. Preferences for the transdermal patch approximately doubled (from 3.2 % pre-counselling to 7 %; p < 0.0001) and those for the vaginal ring increased four-fold (from 5.2 to 21.2 %; p < 0.0001), while preference for the pill remained unchanged (from 64.5 % [pre-] to 64.1 % [post-counselling]). The proportion of undecided women decreased from 18 to 2.1 % (p < 0.0001). The main reasons for choosing a method were related to ease of use (all methods), and preferences for administration frequency (daily, weekly or monthly). The number of patients requiring post-counselling contact with the physician's office was low (5.1-6.9 %), as was the incidence of adverse events (1.8-3.1 %).

CONCLUSIONS

Counselling has a significant impact on women's choice of combined hormonal contraception and encourages them to consider alternative methods to combined oral contraceptives. Moreover, it also enables women to use their chosen method with confidence.

Intrauterine devices and other forms of contraception: thinking outside the pack

A variety of contraception options are available in addition to traditional combined oral contraceptive pills. Newer long-acting reversible contraceptive (LARC) methods such as intrauterine devices and subcutaneous implants are preferred because they do not depend on patient compliance. They are highly effective and appropriate for most women. Female and male sterilization are other effective but they are irreversible and require counseling to minimize regret. The contraceptive injection, patch, and ring do not require daily administration, but their typical efficacy rates are lower than LARC methods and similar to those for combined oral contraceptive pills.

Oral contraception

Oral contraception (OC) remains a popular noninvasive, readily reversible approach for pregnancy prevention and, largely off label, for control of acne, hirsutism, dysmenorrhea, irregular menstruation, menorrhagia, and other menstrual-related symptoms. Many OC formulations exist, with generics offering lower cost and comparable efficacy. Certain medical conditions, including hypertension, migraine, breast cancer, and risk of venous thromboembolism (VTE), present contraindications. Blood pressure measurement is the only physical examination or testing needed before prescription. Although no OC is clearly superior to others, OCs containing the second-generation progestin levonorgestrel have been associated with lower VTE risk than those containing other progestins.

Influence of structured counseling on women's selection of hormonal contraception in Israel: results of the CHOICE study

Background

The multinational CHOICE (Contraceptive Health Research Of Informed Choice Experience) study evaluated the effects of structured counseling on women’s contraceptive decisions, their reasons for making those decisions, and their perceptions of combined hormonal contraceptive (CHC) methods in eleven countries. The aim of this paper to present data from the 1,802 women participating in Israel’s CHOICE program.

Methods

Women (aged 17–40 years) who consulted their health care providers about contraception and who would consider a CHC method qualified to participate. After indicating their intended CHC method, the women received counseling about the daily pill, weekly patch, and monthly vaginal ring. After counseling, the women completed a questionnaire about their contraceptive decisions.

Results

Before counseling, 67%, 6%, and 5% of women (mean age 27 years) intended to use the pill, patch, or ring, respectively. Counseling significantly influenced the women’s CHC choice, with 56%, 12%, and 23% of women selecting the pill, patch, or ring (P<0.0001 for all contraceptive methods versus before counseling). Logistic regression analysis suggested that age significantly increased the probability of switching from the pill to the ring.

Conclusion

Although the pill was the most popular choice overall, counseling appeared to influence Israeli women’s contraceptive decisions, with significantly more women selecting the patch. More than four times as many women selected the ring after counseling than before counseling.

Development and remission of depressive symptoms and treatment with hormonal contraceptives

We present two cases of female patients with a history of depression who developed depressive symptoms after treatment with hormonal contraceptives (HC) in the form of combined oral contraceptive pill, progestin-only pill and combined contraceptive vaginal ring. The presented two cases are based on the women's medical records complemented by personal interviews. The existing literature on the effects of HC on depression is inconclusive. Patient-based decisions with consideration of the individual history and predispositions are recommended when starting oral contraceptives. If depressive symptoms occur, decisions regarding discontinuation need to be made on an individual basis.

New and emerging contraceptives: a state-of-the-art review

Background

The first hormonal contraceptive was introduced onto the market in several countries 50 years ago; however, the portfolio of contraceptive methods remains restricted with regards to their steroid composition, their cost, and their ability to satisfy the requirements of millions of women/couples in accordance with their different reproductive intentions, behaviors, cultures, and settings.

Methods

A literature review was conducted using Medline, Embase, and Current Contents databases, up to September 1, 2013 to identify publications reporting new contraceptives in development using combinations of the search terms: contraception, contraceptives, oral contraceptives, patch, vaginal ring, implants, intrauterine contraceptives, and emergency contraception (EC). Also, several experts in the field were also consulted to document ongoing projects on contraception development. Additionally, the Clinicaltrial.gov website was searched for ongoing studies on existing contraceptive methods and new and emerging female contraceptives developed over the past 5 years. Information was also obtained from the pharmaceutical industry.

Results

Early sexual debut and late menopause means that women may require contraception for up to 30 years. Although oral, injectable, vaginal, transdermal, subdermal, and intrauterine contraceptives are already available, new contraceptives have been developed in an attempt to reduce side effects and avoid early discontinuation, and to fulfill women’s different requirements. Research efforts are focused on replacing ethinyl-estradiol with natural estradiol to reduce thrombotic events. In addition, new, less androgenic progestins are being introduced and selective progesterone receptor modulators and new delivery systems are being used. In addition, research is being conducted into methods that offer dual protection (contraception and protection against human immunodeficiency virus transmission), and contraceptives for use “on demand.” Studies are also investigating non-hormonal contraceptive methods that have additional, non-contraceptive benefits.

Conclusion

The most pressing need worldwide is, first, that the highly effective contraceptive methods already available should be affordable to most of the population and also that these methods should fulfill the needs of women of different ages and with different reproductive requirements. The development of new contraceptive methods should also take advantage of the knowledge obtained over the past 30 years on gamete physiology and gamete interaction to avoid the use of steroid compounds.
