Key clinical point: African American males aged 14-15 years were more likely than 18- to 19- year-old males to use a condom the last time they had sex.

Major finding: Increased condom use was associated with personal factors including high positive attachment to the boyfriend/girlfriend as was a greater number of sexual partners, younger age at first sexual encounter, and knowledge that the individual had a sexually-transmitted infection in the past year.

Study details: The data come from the Mobile Youth Survey, a community-based survey of adolescents in Mobile, Alabama, between 1998 and 2011; the study population included 3,718 individuals.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.

Immediate postpartum long-acting reversible contraception (LARC) represents a safe and effective contraceptive strategy. Despite national guidelines recommending universal patient access, hospitals face significant barriers to offering inpatient LARCs. It is unclear why some hospitals successfully implement immediate postpartum LARCs, while others do not.

Moniz et al conducted a comparative, multiple case study of immediate postpartum LARC implementation at eleven “early adopter” U.S. hospitals and analyzed each hospital’s implementation strategy to produce generalizable knowledge about how and under what circumstances implementation of immediate postpartum LARCs unfold successfully. Between 2017-2018, the authors conducted single-day site visits and 78 semi-structured interviews with a variety of stakeholders (clinician champions, nurses, pharmacists, revenue cycle staff, and hospital administration). On average, sites used 18 (range 11-22) implementation strategies, including assessing institutional readiness for, and barriers to, implementation of immediate postpartum LARC, engaging reproductive justice experts and community resources to address social determinants of health, involving patients in implementation planning, and developing quality monitoring processes to evaluate clinical processes and outcomes. The researchers found that successful implementation of immediate postpartum LARC required three essential conditions: effective implementation champions who are supported by a multidisciplinary implementation team; creating an enabling financial environment; and engaging hospital administration. Additional findings from this study call for more support for individuals leading change in complex care settings, intentionally designing implementation interventions that take into account local contextual influences, and meaningfully engaging patients in the implementation process.

Of postpartum women, 61% in low- and middle-income countries (LMIC) have an unmet contraceptive need and many face high rates of short interpregnancy intervals (Moore). Additionally, 51%-96% of postpartum women in LMIC use short-acting methods of contraception (Moore), further highlighting the need for increased access to immediate postpartum LARC in LMIC. Data on the use and continuation of immediate postpartum LARC in LMIC is limited. Marchin et al conducted a systematic review and meta-analysis to determine 6-month continuation rates of immediate postpartum LARCs among women in 69 low-income countries that were enrolled in the Family Planning 2020 initiative. The meta-analysis ultimately focused on the copper IUD due to the absence of relevant studies on other LARC methods. The meta-analysis of 12 studies resulted in a pooled 6-month continuation rate for immediate postpartum copper IUDs of 87%, a rate comparable to continuation rates found in higher-income countries. This estimate had significant heterogeneity between studies. Secondary outcomes of expulsion, removal, and infection rates were low at 6%, 5%, and 0.2% respectively. High 6-month continuation rates and a low rate of adverse outcomes suggest immediate postpartum copper IUD insertion represents a feasible and acceptable postpartum contraceptive option for women living in LMIC.

In cases where contraception methods fail, are used incorrectly, or are not used at all, emergency contraception (EC) can be used after intercourse to prevent pregnancy. Timely access to, and accurate knowledge of, EC are especially important for rural women who are more likely to experience an unintended pregnancy resulting in a live birth compared to urban women. Milkowski et al analyzed publicly available data from the National Survey of Family Growth to estimate differences in oral EC use, access, and counseling by rural-urban county of residence among U.S. women aged 15-44 years. 10% of rural and 19% of urban women who had ever been sexually active reported ever using EC pills. Over the course of the study period (2006-2017), the percentage of women reporting ever-use of EC increased linearly in both rural and urban populations, with the prevalence of EC ever-use more than doubling in each group. This observation likely reflects an overall increase in EC use during a time period in which the federal government enacted several policies to improve access to EC. The study findings also highlight the need for improved patient counseling on EC. While the overall prevalence of EC counseling was low among all women, rural women were less likely to have received counseling on EC when compared to urban women.

Although many studies report weight gain in users of progestin-only hormonal contraception (POC), a recent Cochrane systematic review found that there was insufficient evidence to determine the effect of POCs on weight (Lopez). Beksinska et al conducted a secondary analysis of prospective weight change among women enrolled in the Evidence for Contraceptive options and HIV Outcomes (ECHO) trial, which was an open label, prospective, randomized multicenter trial that compared the risk of HIV acquisition among women randomized to injectable contraception (DMPA), the copper IUD, or a second generation two rod levonorgestrel (LNG) implant Jadelle^Ò. This trial was conducted at 12 sites across four African countries between 2015 and 2018. Eligible study participants were nonpregnant, HIV negative, sexually active women aged 16-35 years who desired contraception. The final sample size included 7,014 women randomly assigned to receive DMPA (2,293), the LNG implant (2,372), or the copper IUD (2,349). Using a standardized protocol and calibrated equipment across all study sites, weight and height were measured at baseline and at study exit at 12, 15, or 18 months. The mean weight increased amongst all three contraceptive groups and was significantly different in magnitude, with the largest gain in the DMPA group (3.5 kg), 2.4 kg in the LNG implant group, and 1.5 kg in the copper IUD group. Unlike copper IUD users, women in the DMPA and LNG implant group continued to gain weight after 1 year of contraceptive use. It is noteworthy that, regardless of contraceptive method allocation, not all women gained weight and a small proportion of women lost weight. When choosing a contraceptive method, women using POCs should be counselled about the potential side effect of weight gain.

Immediate postpartum long-acting reversible contraception (LARC) represents a safe and effective contraceptive strategy. Despite national guidelines recommending universal patient access, hospitals face significant barriers to offering inpatient LARCs. It is unclear why some hospitals successfully implement immediate postpartum LARCs, while others do not.

Moniz et al conducted a comparative, multiple case study of immediate postpartum LARC implementation at eleven “early adopter” U.S. hospitals and analyzed each hospital’s implementation strategy to produce generalizable knowledge about how and under what circumstances implementation of immediate postpartum LARCs unfold successfully. Between 2017-2018, the authors conducted single-day site visits and 78 semi-structured interviews with a variety of stakeholders (clinician champions, nurses, pharmacists, revenue cycle staff, and hospital administration). On average, sites used 18 (range 11-22) implementation strategies, including assessing institutional readiness for, and barriers to, implementation of immediate postpartum LARC, engaging reproductive justice experts and community resources to address social determinants of health, involving patients in implementation planning, and developing quality monitoring processes to evaluate clinical processes and outcomes. The researchers found that successful implementation of immediate postpartum LARC required three essential conditions: effective implementation champions who are supported by a multidisciplinary implementation team; creating an enabling financial environment; and engaging hospital administration. Additional findings from this study call for more support for individuals leading change in complex care settings, intentionally designing implementation interventions that take into account local contextual influences, and meaningfully engaging patients in the implementation process.

Of postpartum women, 61% in low- and middle-income countries (LMIC) have an unmet contraceptive need and many face high rates of short interpregnancy intervals (Moore). Additionally, 51%-96% of postpartum women in LMIC use short-acting methods of contraception (Moore), further highlighting the need for increased access to immediate postpartum LARC in LMIC. Data on the use and continuation of immediate postpartum LARC in LMIC is limited. Marchin et al conducted a systematic review and meta-analysis to determine 6-month continuation rates of immediate postpartum LARCs among women in 69 low-income countries that were enrolled in the Family Planning 2020 initiative. The meta-analysis ultimately focused on the copper IUD due to the absence of relevant studies on other LARC methods. The meta-analysis of 12 studies resulted in a pooled 6-month continuation rate for immediate postpartum copper IUDs of 87%, a rate comparable to continuation rates found in higher-income countries. This estimate had significant heterogeneity between studies. Secondary outcomes of expulsion, removal, and infection rates were low at 6%, 5%, and 0.2% respectively. High 6-month continuation rates and a low rate of adverse outcomes suggest immediate postpartum copper IUD insertion represents a feasible and acceptable postpartum contraceptive option for women living in LMIC.

In cases where contraception methods fail, are used incorrectly, or are not used at all, emergency contraception (EC) can be used after intercourse to prevent pregnancy. Timely access to, and accurate knowledge of, EC are especially important for rural women who are more likely to experience an unintended pregnancy resulting in a live birth compared to urban women. Milkowski et al analyzed publicly available data from the National Survey of Family Growth to estimate differences in oral EC use, access, and counseling by rural-urban county of residence among U.S. women aged 15-44 years. 10% of rural and 19% of urban women who had ever been sexually active reported ever using EC pills. Over the course of the study period (2006-2017), the percentage of women reporting ever-use of EC increased linearly in both rural and urban populations, with the prevalence of EC ever-use more than doubling in each group. This observation likely reflects an overall increase in EC use during a time period in which the federal government enacted several policies to improve access to EC. The study findings also highlight the need for improved patient counseling on EC. While the overall prevalence of EC counseling was low among all women, rural women were less likely to have received counseling on EC when compared to urban women.

Although many studies report weight gain in users of progestin-only hormonal contraception (POC), a recent Cochrane systematic review found that there was insufficient evidence to determine the effect of POCs on weight (Lopez). Beksinska et al conducted a secondary analysis of prospective weight change among women enrolled in the Evidence for Contraceptive options and HIV Outcomes (ECHO) trial, which was an open label, prospective, randomized multicenter trial that compared the risk of HIV acquisition among women randomized to injectable contraception (DMPA), the copper IUD, or a second generation two rod levonorgestrel (LNG) implant Jadelle^Ò. This trial was conducted at 12 sites across four African countries between 2015 and 2018. Eligible study participants were nonpregnant, HIV negative, sexually active women aged 16-35 years who desired contraception. The final sample size included 7,014 women randomly assigned to receive DMPA (2,293), the LNG implant (2,372), or the copper IUD (2,349). Using a standardized protocol and calibrated equipment across all study sites, weight and height were measured at baseline and at study exit at 12, 15, or 18 months. The mean weight increased amongst all three contraceptive groups and was significantly different in magnitude, with the largest gain in the DMPA group (3.5 kg), 2.4 kg in the LNG implant group, and 1.5 kg in the copper IUD group. Unlike copper IUD users, women in the DMPA and LNG implant group continued to gain weight after 1 year of contraceptive use. It is noteworthy that, regardless of contraceptive method allocation, not all women gained weight and a small proportion of women lost weight. When choosing a contraceptive method, women using POCs should be counselled about the potential side effect of weight gain.

Patients receive the full range of contraception options when providers are educated on the proper use and spectrum of contraceptive options. When an educational intervention was introduced in three countries (Democratic Republic of Congo, Somalia, and Pakistan), aimed at training providers on counseling and provision of immediate postpartum LARC, a significant number of women opted for LARC. This was in comparison to countries that did not implement this educational intervention (Rwanda, Syria, Yemen). The rate of LARC adoption was 10.01% versus 0.77%, respectively in countries providing the educational intervention versus those that did not. 

The copper IUD has long been utilized for emergency contraception, providing nearly 100% efficacy in pregnancy prevention, as well as long-acting, reversible contraception. Recently, the levonorgestrel (LNG) IUD was considered for similar use as emergency contraception. Turok et al studied the pregnancy rate of the LNG IUD compared the copper IUD and found that the LNG IUD was noninferior to the copper IUD when used for emergency contraception, with pregnancy rates of 1 in 317 (LNG) compared to 0 in 321 (copper). LNG IUDs are often more readily available in OBGYN offices and could improve access to higher efficacy emergency contraception compared to traditional emergency contraceptive pills.

When placing IUDs, providers have a range of devices to measure the length of the uterus for correct IUD placement, including endometrial biopsy pipelles, uterine sounds, both plastic and metal, as well as the device inserters. In a biomechanical ex vivo analysis, Duncan et al examined the maximum force generated for IUD placement with the levonorgestrel placement instrument, the copper IUD placement instrument, and a metal sound. Using their model, the investigators found that the metal sound caused uterine perforation, but the plastic IUD placement device did not. Although the study authors utilized the device inserters themselves, we recommend the use of plastic uterine sounds or biopsy pipelles over the device inserters in accordance with IUD packaging instructions.  IUD packaging should not be opened until both the ability to access the uterine cavity and appropriate uterine size are determined to avoid needing to discard the IUD.

With the introduction of new technology to vaccinate the world with the Pfizer and Moderna mRNA vaccines, I considered other health conditions that could benefit from new modalities. Unplanned pregnancies are a public health crisis, yet the burden falls solely on women to solve, burdening them with contraceptive practices to prevent unplanned pregnancy. With the insurrection of Row v. Wade and the new bills being pushed through states that are limiting abortion, perhaps the time has come for males to accept the responsibility for contraception to prevent unplanned pregnancy. The methods that currently exist for males are condoms and vasectomy. Other options are being explored – both nonhormonal and reversible contraception including daily pills, gels, and long-acting injections.

The pill for men has been under preliminary trials with promising results. This contraceptive pill contains dimethandrolone undecanoate, which is an androgen anabolic steroid progesterone once-daily pill that suppresses FSH and LH, causing a decrease in the production of testosterone and consequently sperm production.¹ (Long, Lee, & Blithe, 2019). This pill is in long-term trials to determine the efficacy and side effects, including the impact on libido, liver, and kidney disease.

The injectable male contraceptive in trials now includes two different options. The first was a long-acting progestin, testosterone, and androgen combination. The male participants received an intramuscular injection every 8 weeks. Although the results of the study were promising – sperm production was effectively reduced, the side effects were too severe for participants to continue use. Side effects much like those of the female Depo-Provera injections included acne and mood disorders. Men experienced erectile dysfunction while at the same time having an increase in sex drive.² (Em, 2018).

Recently, researchers in India have studied a nonhormonal injectable with promising outcomes. It prevented pregnancy in more than 97% of participants. This injectable polymer gel is placed into the male’s vas deferens to block sperm from leaving the body. This product inactivates sperm, essentially creating temporary sterilization for men. The benefit of this product, called RISUG (reversible inhibition of sperm under guidance), is a single injection that can be effective for 13 years. It can be reversed earlier if needed by injecting a dissolving gel into the male’s vas deferens.^1,2 In the United States, there is an identical product called Vasalgel – a polymer injected into the vas deferens – also being studied for temporary infertility.

Another synthetic implanted androgen product being studied is 7 alpha-methyl-19-nortestosterone (MENT), a synthetic steroid that resembles testosterone but does not convert into testosterone and, consequently, does not stimulate prostate growth. It is administered via two subdermal implants and is effective for 12 months. The first subdermal implant releases the synthetic androgen, which is more potent than testosterone, and the other emits LH-releasing hormone.³ Studies demonstrate that MENT suppresses sperm production.¹

Finally, studies are underway using transdermal gel applications to suppress sperm concentrations. The daily gel is absorbed through the skin after application to two different areas of the man’s body: the shoulders and upper arms. The daily application of the progestin product, Nestorone, and testosterone gel has been found to reduce sperm concentrations to < 1 x 10⁶/mL. Studies measured gonadal concentrations after 4 weeks.¹ Users were happy with the use of a topical gel, with minimal side effects such as lower libido, weight gain, and changes in cholesterol, yet inconsistent use of the product resulted in lower than anticipated results.⁴

Male contraceptive options are long overdue to dramatically reduce the rate of unplanned pregnancies and the burden of contraception placed on women. Getting these products to market will be half the battle – getting men to commit to using these options and women to trust male compliance may further impede acceptance. Men have not had to carry the burden and economics of single parenting. Men interested in casual sex may now need to accept more responsibility for unplanned pregnancy and be proactive with prevention, particularly as abortion laws are being challenged.
