RESUMEN

OBJECTIVE: To estimate the potential market for novel male contraceptives (NMCs) using United States National Survey of Family Growth (NSFG) data, 2015-2017. STUDY DESIGN: We described the market for NMCs via secondary analysis of the 2015-2017 NSFG's weighted male respondent data, utilizing surrogate markers for contraceptive switching (NSFG) and contraceptive discontinuation data from the Contraceptive CHOICE project. Potential NMC users included men relying on: (1) no methods or less effective methods but who reported that they would be "very upset" if they got someone pregnant, (2) permanent methods but who reported that they might still want more children, (3) a female partner's method that she might discontinue in the next year, (4) a male method even when his partner uses her own contraceptive. RESULTS: Of 3340 respondents-representing 55,890,830 sexually active, reproductive-age men-23.2% used no contraception at last intercourse, 15.8% condoms, 5.1% withdrawal, and 5.1% vasectomy. Among respondents relying solely on condoms, withdrawal, or no method, 19.7%, 3.8%, and 4.4% would be "very upset" if they got someone pregnant. For permanent contraceptive users, 17.3%-20.5% wanted another child. For men reliant on their partner's long-acting reversible or combined hormonal contraceptive, 12-17% and 45-51% of partners might discontinue their method. These data conservatively suggest that 13% or more than 7 million men would potentially use NMCs, rising to 15.5 million with less restrictive contraceptive switching criteria. CONCLUSION: Adjusting for pregnancy attitudes and likelihood of contraceptive switching, a substantial portion (between 7-15.5 million) of reproductive age men in the US are potential NMC users. IMPLICATIONS: The population of potential novel male contraceptive users extends beyond just users of condoms, withdrawal and vasectomy and should include couples practicing dual-partner contraception and female partners using contraceptive methods that they may become dissatisfied with and discontinue.

RESUMEN

BACKGROUND: Intrauterine devices (IUDs) have comparable efficacy to permanent surgical contraceptive methods; however, long-term costs are infrequently considered. Existing estimates inconsistently account for costs outside of IUD insertion or removal, actual duration of use, or differences between hormonal and nonhormonal IUDs. OBJECTIVE: To describe health care resource utilization and commercial payer costs that arise throughout hormonal and nonhormonal IUD use. METHODS: In this retrospective cohort study, paid claims data (Merative, MarketScan) from a large US commercial claims database were evaluated between 2013 and 2019. Claims were included from individuals aged 12 to 45 years who had an IUD inserted in 2014, continuous insurance coverage for 1 year prior to insertion and throughout follow-up, and no insertion, removal, or reinsertion in the previous year. Procedures and services that could be IUD-related were identified using Current Procedural Terminology and International Classification of Diseases, Ninth and Tenth Edition codes. Duration of IUD use was evaluated by Kaplan-Meier analysis of time to IUD removal. Event rates were determined for identified procedures and services; costs were calculated as the sum of payer reimbursements per enrolled individual. All IUD types available during the study period were described: 2 hormonal IUDs (52-mg and 13.5-mg levonorgestrel-releasing [LNG]) and the nonhormonal (380-mm2 copper) IUD. RESULTS: Of 195,009 individuals meeting the age requirement and receiving an IUD in 2014, 63,386 met the inclusion criteria and 53,744 had their IUD type on record-42,777 (67.5%) 52-mg LNG, 2,932 (4.6%) 13.5-mg LNG, and 8,035 (12.7%) nonhormonal IUD users. Despite differences in their indicated duration (13.5-mg LNG, 3 years; 52-mg LNG, 5 years; and nonhormonal, 10 years), most individuals had their IUD removed before its indicated full duration of use (13.5-mg LNG, 56.1%; 52-mg LNG, 61.3%; nonhormonal [at 5 years], 54.6%). The event rate per 100 individuals during the follow-up period was highest for abnormal uterine bleeding (16.2), ovarian cysts (9.3), and surgical management of uterine perforations (4.5). IUD insertion costs (mean ± SE) per enrolled individual for the 13.5-mg LNG, 52-mg LNG, and nonhormonal IUDs were $931 ± $9, $1,107 ± $4, and $897 ± $6, respectively. Cumulative mean ± SE 5-year postinsertion costs for the 13.5-mg LNG, 52-mg LNG, and nonhormonal IUDs were $2,892 ± $232, $1,514 ± $31, and $1,389 ± $97, respectively, among the remaining enrolled individuals. CONCLUSIONS: In this descriptive study of commercially insured IUD users, at least half had their IUD removed before its indicated duration. IUD improvements that reduce the frequency of abnormal uterine bleeding, ovarian cysts, and uterine perforations may help reduce long-term IUD costs.

RESUMEN

Congenital hydrocephalus was once a permanently disabling and even fatal disease. With the advent of ventriculoperitoneal shunts, affected women are now surviving to their reproductive years and beyond. Pregnancy outcomes in this population are generally positive. However due to possible shunt complications, including infection, migration, and organ perforation, perinatal care for pregnant individuals with a ventriculoperitoneal shunt is complex and requires input from both obstetric and neurosurgical providers. We present the case of a 28-year-old G1P1 with a history of congenital hydrocephalus and ventriculoperitoneal shunt who presented to the emergency department at two months postpartum with clear fluid leaking from her vagina. The shunt's distal end had migrated and perforated the uterus causing cerebrospinal fluid to leak into the uterine cavity. Surgical repair was required of both the uterine hysterotomy and ventriculoperitoneal shunt, and the patient's symptoms ultimately resolved. Patients with a history of shunt placement who later undergo abdominal surgery, including cesarean section, are at risk for shunt complications. Shunt-dependent patients presenting in the post-partum period with new neurological or abdominopelvic complaints should undergo evaluation by a multidisciplinary team.

RESUMEN

Though racial and ethnic disparities in sexual and reproductive health outcomes are receiving greater interest and research funding, the experiences of Asian American and Native Hawaiian and Other Pacific Islander (NHPI) people are often combined with those of other racial and ethnic minority groups or excluded from data collection altogether. Such treatment is often rationalized because Asian American and NHPI groups comprise a smaller demographic proportion than other racial or ethnic groups, and the model minority stereotype assumes that these groups have minimal sexual and reproductive health needs. However, Asian American and NHPI people represent the fastest-growing racial-ethnic groups in the United States, and they face disparities in sexual and reproductive health access, quality of care, and outcomes compared with those of other races and ethnicities. Disaggregating further by ethnicity, people from certain Asian American and NHPI subgroups face disproportionately poor reproductive health outcomes that suggest the need for culturally targeted exploration of the unique drivers of these inequities. This commentary highlights the evidence for sexual and reproductive health disparities both in and between Asian American and NHPI groups. We also examine the failures of national data sets and clinical studies to recruit Asian American and NHPI people in proportion to their share of the U.S. population or to consider how the cultural and experiential diversity of Asian American and NHPI people influence sexual and reproductive health. Lastly, we provide recommendations for the equitable inclusion of Asian American and NHPI people to promote and systematize the study and reporting of sexual and reproductive health behaviors and outcomes in these culturally, religiously, and historically diverse groups.

RESUMEN

Objective: To characterize the family-building goals and experiences of lesbians compared with those of heterosexual females in the United States. Design: Secondary analysis of nationally representative, cross-sectional survey data. Setting: National Survey of Family Growth 2017-2019. Patients: 159 reproductive-age lesbian respondents and 5,127 reproductive-age heterosexual respondents. Interventions: We characterized family-building goals and the use of assisted reproduction and adoption among lesbians using nationally representative female respondent data from the 2017-2019 National Survey of Family Growth. We performed bivariate analyses examining variations in these outcomes between lesbian and heterosexual individuals. Main Outcome Measures: Wantedness of children, use of assisted reproductive technology, and pursuit of adoption among reproductive-age lesbian and heterosexual participants. Results: We identified 159 reproductive-age lesbian respondents of the National Survey of Family Growth, representing 2.3% or approximately 1.75 million US individuals of reproductive age. The lesbian respondents were younger, less religious, and less likely to have children than heterosexual respondents. These groups did not differ significantly by race/ethnicity, education, or income. More than half of the individuals reported wanting a child in the future, with proportions similar between the lesbian and heterosexual individuals (48% vs. 51%, respectively; P = .52). Accordingly, 18% of both the lesbian and heterosexual individuals reported that they would be greatly bothered if they were unable to have children. Nevertheless, health care providers reportedly asked the lesbians about their desire to get pregnant less frequently than they asked the heterosexual individuals (21% vs. 32%, respectively; P = .04). Only 26% of the lesbians had ever been pregnant compared with 64% of the heterosexual individuals (P<.01). Approximately one third (31%) of lesbians with medical insurance were seeking reproductive services compared with 10% of heterosexual individuals (P = .05). Lesbians were significantly more likely to be seeking adoption than heterosexual individuals (7.0% vs. 1.3%, respectively; P = .01), although they were more likely to report being turned down (17% vs. 10%, respectively; P = .03), not knowing why they were unable to adopt (19% vs. 1%, respectively; P = .02), and quitting because of the adoption process (100% vs. 45%, respectively; P = .04). Conclusions: Approximately half of US females of reproductive age desire to have a child, a proportion that is not different between lesbian and heterosexual individuals. However, fewer lesbians are asked about their desires to get pregnant, and fewer ever become pregnant. Lesbians are significantly more likely to pursue assisted reproductive services when covered by insurance and more likely to seek adoption. Unfortunately, lesbians are more likely to face challenges with adoption.

RESUMEN

Injectable male hormonal contraceptives are effective for preventing pregnancy in clinical trials; however, users may prefer to avoid medical appointments and injections. A self-administered transdermal contraceptive gel may be more acceptable for long-term contraception. Transdermal testosterone gels are widely used to treat hypogonadism and transdermal administration may have utility for male contraception; however, no efficacy data from transdermal male hormonal contraceptive gel are available. We designed and are currently conducting an international, multicenter, open-label study of self-administration of a daily combined testosterone and segesterone acetate (Nestorone) gel for male contraception. The transdermal approach to male contraception raises novel considerations regarding adherence with the daily gel, as well as concern about the potential transfer of the gel and the contraceptive hormones to the female partner. Enrolled couples are in committed relationships. Male partners have baseline normal spermatogenesis and are in good health; female partners are regularly menstruating and at risk for unintended pregnancy. The study's primary outcome is the rate of pregnancy in couples during the study's 52-week efficacy phase. Secondary endpoints include the proportion of male participants suppressing sperm production and entering the efficacy phase, side effects, hormone concentrations in male participants and their female partners, sexual function, and regimen acceptability. Enrollment concluded on November 1, 2022, with 462 couples and enrollment is now closed. This report outlines the strategy and design of the first study to examine the contraceptive efficacy of a self-administered male hormonal contraceptive gel. The results will be presented in future reports. IMPLICATIONS: The development of a safe, effective, reversible male contraceptive would improve contraceptive options and may decrease rates of unintended pregnancy. This manuscript outlines the study design and analysis plan for an ongoing large international trial of a novel transdermal hormone gel for male contraception. Successful completion of this and future studies of this formulation may lead to the approval of a male contraceptive.

RESUMEN

INTRODUCTION: Black pregnant individuals endure a disproportionate burden of preventable morbidity and mortality due to persistent, racially mediated social and systemic inequities. As patient advocates, Black community-based doulas help address these disparities via unique services not provided by conventional doulas. However, Black doulas themselves may encounter obstacles when providing care to Black perinatal clients. We characterized the barriers encountered by Black community-based doulas in Los Angeles, California. METHODS: We partnered with a Black community-based doula program to conduct semistructured interviews with its community doulas and program directors, covering the following topics: motivations for becoming a doula, services provided, and challenges faced as a Black doula in perinatal settings. Interview transcripts were reviewed via directed content analysis, with attention to the influence of systemic racism on service provision. Additionally, our research team used Camara Jones' Levels of Racism, which describes race-associated differences in health outcomes to code data. RESULTS: We interviewed 5 Black community-based doulas and 2 program directors, who all shared experiences of inequitable care and bias against Black clients that could be addressed with the support and advocacy of culturally congruent doulas. The community doulas shared experiences of stigma as Black doulas, compounded by racial prejudice. Interviewees noted sources of structural racism affecting program development, instances of interpersonal racism as they interacted with the health care system, and internalized racism that was revealed during culturally based doula trainings. Additionally, the doulas emphasized the importance of cultural concordance, or a shared identity with clients, which they considered integral to providing equitable care. CONCLUSION: Despite facing institutionalized, interpersonal, and internalized forms of racism, Black community-based doulas provide avenues for Black birthing individuals to navigate systemic racism experienced during the perinatal process. However, these forms of racism need to be addressed for Black community doulas to flourish.

RESUMEN

OBJECTIVES: To explore the association of men's willingness to use a novel male contraceptive with their attitudes toward gender equity. STUDY DESIGN: We conducted an anonymous online survey examining willingness to use male contraception among reproductive-age (18-50 years) cisgender men from the United States and Canada, recruited via online forums, social media ads, and male contraceptive mailing lists from April through July of 2022. We collected sociodemographics and reproductive histories and used a 20-item Gender-Equitable Men Scale to examine men's gender role attitudes. We conducted bivariate analyses to inform a multivariable logistic regression isolating the independent influence of increasingly gender-equitable attitudes on cis-men's willingness to use novel male contraceptives. RESULTS: We received 2066 surveys from primarily white (n = 1192; 58%), heterosexual (n = 1816; 88%), married cis-men (n = 1008; 49%), below age 30 (n = 1010; 49%), and who had not completed a bachelor's degree (n = 1173; 57%). The majority reported sex multiple times per week (n = 946; 46%), but had never gotten someone pregnant (n = 907; 44%); nearly half (n = 994; 48%) identified as parents. Three-quarters of respondents reported being willing to use novel male contraceptives (n = 1545; 75%); willingness was independently linked to having had an abortion (adjOR: 2.04; 95% CI: 1.37-3.02) and increasing total Gender-Equitable Men Scale scores (adjOR: 1.05; 95% CI: 1.02-1.08), even after controlling for age, race/ethnicity, and education. CONCLUSIONS: Three-quarters of cis-men surveyed reported willingness to use new male contraceptives, which was correlated with increasingly gender-equitable attitudes. IMPLICATIONS: As gender-equitable attitudes are linked to men's willingness to use novel male contraceptives, older population surveys may underestimate male contraceptive demand. Further, given the association of abortion experience with willingness to use novel male contraceptives, abortion-providing clinics may be considered for future dissemination of male contraceptives.

RESUMEN

BACKGROUND: Several studies have investigated the effectiveness of intrauterine device placement at cesarean delivery as a contraceptive method. However, national-level use and outcomes of a postplacental intrauterine device at cesarean delivery are currently understudied in the United States. OBJECTIVE: This study aimed to examine the trends, characteristics, and outcomes of patients who received a postplacental intrauterine device at cesarean delivery. STUDY DESIGN: This retrospective cohort study used the National Inpatient Sample. The study cohort included patients who underwent cesarean delivery from October 2015 to December 2018. The exclusion criteria included hemorrhage, chorioamnionitis, uterine anomaly, hysterectomy, and permanent surgical sterilization. Eligible cases were grouped on the basis of the use of a postplacental intrauterine device at cesarean delivery. The primary outcome measures were temporal trends and characteristics associated with the use of a postplacental intrauterine device at cesarean delivery, assessed using the generalized estimating equation model in multivariable analysis. The secondary outcome measure was perioperative morbidity (leukocytosis, endometritis, myometritis, and sepsis). Propensity score matching was used to balance the baseline characteristics. RESULTS: Among 2,983,978 patients who met the inclusion criteria, 10,145 patients (0.3%) received a postplacental intrauterine device at cesarean delivery. The use of a postplacental intrauterine device increased from 0.1% in the fourth quarter of 2015 to 0.6% in the fourth quarter of 2018 (P<.001). In a multivariable analysis, the use of a postplacental intrauterine device increased by 14% every quarter-year (adjusted odds ratio, 1.14; 95% confidence interval, 1.13-1.15). In addition, (1) patient characteristics of young age, non-White race, obesity, tobacco use, lowest quartile median household income, and insured with Medicaid; (2) hospital characteristics of large bed capacity and urban teaching setting in Northeast region; and (3) pregnancy characteristics of early gestational age at cesarean delivery, hypertensive disease, previous cesarean delivery, multifetal pregnancy, grand multiparity, placenta previa, and nonelective cesarean delivery represented the independent characteristics associated with the use of a postplacental intrauterine device (all P<.05). A regression tree model identified 35 discrete patterns of the use of a postplacental intrauterine device based on 8 factors (time, race or ethnicity, primary expected payer, obesity, hospital bed capacity, hospital teaching status, hospital region, and previous cesarean delivery). There were 9 patterns, representing 8.8% of the study population, exhibiting a use rate of ≥1.0%, whereas there were 7 patterns, representing 16.0% of the study population, exhibiting no use of a postplacental intrauterine device (absolute rate difference from the highest group to the lowest group, 4.7%). In a propensity score-matched model, postplacental intrauterine device placement at cesarean delivery was not associated with increased risk of measured morbidity (any, 1.8% vs 1.7%; odds ratio, 1.06; 95% confidence interval, 0.66-1.69; P=.812), including postpartum endometritis (1.2% vs 1.0%; odds ratio, 1.19; 95% confidence interval, 0.67-2.14; P=.554). CONCLUSION: The use of a postplacental intrauterine device at cesarean delivery increased significantly in recent years in the United States.

RESUMEN

Despite evidence-based recommendations from the American College of Obstetricians and Gynecologists and the American College of Medical Genetics to offer prenatal genetic carrier screening for reproductive partners, partner carrier screening or genetic testing is inconsistently covered by pregnant patients' health insurance plans. Health policies that exclude reproductive partners from insurance coverage for prenatal carrier screening or genetic testing contradict multiple ethical principles and can even contribute to adverse maternal-child health outcomes. Incomplete or missing information regarding partner carrier status can lead to costly, invasive, and potentially risky interventions for the pregnant patient that can be avoided by a simple and less expensive blood test in the reproductive partner. Lack of information regarding carrier status also harms the neonate by obviating an opportunity for early detection and treatment of potential medical complications. Insurance policies that exclude coverage for paternal genetic testing perpetuate the disproportionate burdens of pregnancy care and risk shouldered by pregnant people. To rectify these ethical dilemmas, partner carrier screening and genetic testing should be considered and covered as routine components of obstetric health care that are covered by health insurance.

RESUMEN

OBJECTIVE: To examine trends in national reporting of broken intrauterine devices (IUDs). STUDY DESIGN: We enumerated IUD device "breakage" reports in the Food and Drug Administration Adverse Event Reporting System from inception (1998) until February 2022. We explored associations of breakage with IUD type (copper versus hormonal), year reported, reporter (consumer versus clinician), and patient characteristics (age and weight). RESULTS: We identified 4144 breakage reports for copper versus 2140 for hormonal IUDs. Among the 170,215 adverse events reported, breaks were disproportionately reported for copper (9.6%) versus hormonal (1.7%) IUDs. CONCLUSION: National pharmacovigilance data suggests disproportionate breakage in copper versus hormonal IUDs though the true prevalence of breaks cannot be calculated from this dataset.

RESUMEN

OBJECTIVE: To determine whether a user-controlled sperm concentration test compared with standard semen analysis can effectively monitor spermatogenesis suppression for male contraception. DESIGN: Single center, prospective sub study of the ongoing clinical trial: "Study of daily application of Nestorone and testosterone combination gel for male contraception." SETTING: Research institute at an academic medical center. PARTICIPANT(S): Couples participating in the male contraceptive clinical trial. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): The ability by participants to monitor sperm suppression to a threshold compatible with contraceptive efficacy utilizing a user-controlled test verified by sperm concentration determined by standard laboratory methods. RESULT(S): Thirty-eight men participating in a hormonal male contraceptive clinical trial provided multiple samples during spermatogenesis suppression for this substudy. Participants, employing a user-controlled test, correctly identified the absence of sperm (a negative test) in 100% of their laboratory-confirmed azoospermic samples (n = 122). Participants also identified 100% of samples (n = 73) with sperm >0.2 million/mL as positive. Sperm counts between 0.01 and 0.2 million/mL were identified as negative in 96% of samples. Trial participants noted the overall ease of using the test with respect to sample preparation, test timing, and result interpretation, and that they could accurately use this test at home without difficulty. CONCLUSION(S): Participants undergoing spermatogenesis suppression in a hormonal male contraceptive trial performed user-controlled test to determine whether their semen sperm concentration was ≤ or >0.2 million/mL. Compared with standard semen analyses, participants correctly identified 100% of samples with sperm counts >0.2 million/mL as positive (Sensitivity 100%). A positive result when the couple is using a male contraceptive method triggers the need for semen analysis by a laboratory while the couple uses another method of contraception. Participants correctly diagnosed samples ≤0.2 million sperm/mL as negative in 99% of samples (specificity 99%). A negative result indicates a sperm concentration ≤0.2 million/mL, well below the threshold of ≤1 million/mL offering contraceptive efficacy demonstrated by prior studies. At-home sperm concentration test would minimize the need for users to return to the clinic to monitor suppression of spermatogenesis, decreasing cost and burden of male contraception trials and increasing practicality of the method. CLINICAL TRIAL REGISTRATION NUMBER: NCT: 03452111.

RESUMEN

OBJECTIVE: To evaluate infectious outcomes following postplacental intrauterine device (PPIUD) placement in patients with suspected chorioamnionitis. STUDY DESIGN: This retrospective cohort study identified individuals desiring PPIUD who subsequently developed suspected chorioamnionitis, treated with antibiotics. We followed 12-month infectious outcomes amongst two cohorts: (1) those who received PPIUD and (2) those with placement deferred. RESULTS: Of 55 followed, 18 of 22 PPIUDs were placed before chorioamnionitis was suspected; 33 placements were deferred. Neither group experienced acute infectious complications. Notably, IUDs were more often deferred when chorioamnionitis was more clearly diagnosed (20/33, 60.6% vs 4/22, 18.2% p < 0.01). Overdiagnosis of chorioamnionitis prevented IUD uptake in 10 of 55 (18.2%) individuals in this sample. CONCLUSIONS: PPIUD placement in individuals with early signs of chorioamnionitis may not result in severe morbidity, in a study limited by sample size. Larger, prospective studies are needed in well-defined cohorts. IMPLICATIONS: Incidental, immediate postplacental IUD placement in individuals with treated, suspected chorioamnionitis was not associated with severe morbidity within 1-year postpartum. Larger-scale, prospective studies are needed to guide the management of incidentally-placed, postplacental IUDs in the setting of mild chorioamnionitis.

RESUMEN

OBJECTIVES: Men who accompany their female partners at the time of an abortion represent a unique population who may be amenable to receiving postabortion contraceptive services. We sought to examine their interest in receiving both counseling and contraception when available. STUDY DESIGN: We analyzed a subset of survey data on the experience of accompanying male partners at the time of an abortion at two urban family planning clinics. We examined their beliefs about shared contraceptive responsibility, attitudes towards participating in contraceptive counseling, and willingness to use novel male contraceptives. We conducted bivariate analyses and logistic regressions for sociodemographic and reproductive factors linked to these outcomes. RESULTS: Of 210 male partners surveyed at the time of an abortion, nearly three-quarters characterized preventing unwanted pregnancy as a shared responsibility, believed in the importance of attending contraceptive counseling with their female partner, and reported willingness to use novel male contraceptives. Contraceptive method used when discovering the pregnancy was neither linked to men's attitudes towards counseling nor interest in using novel male contraceptives. Individuals between the ages of 25 to 34 (aOR: 2.69; 95%CI: 1.32-5.48), those with a college education (aOR: 5.49; 95%CI: 1.31-22.94), and those who had never experienced abortion (aOR: 2.21; 95%CI: 1.08-4.55) exhibited greater interest in using novel male contraceptives. Black respondents (aOR: 2.33; 95%CI: 1.01-5.38) exhibited greater interest in receiving contraceptive counseling with their partner and a counselor following the abortion. CONCLUSION: For male partners, abortion may be an opportunity to engage men in contraceptive counseling and when available, offer new male contraceptives. IMPLICATIONS: As few men receive comprehensive contraceptive counseling, engaging men when they accompany their female partners to family planning clinics may be an additional strategy to prevent unwanted pregnancy.
