Context and Purpose

Globally, at least 20–50% of men and women living with HIV want to have children [1,2,3,4]. For many HIV-affected individuals and couples, attempting pregnancy introduces risks of HIV transmission to infants and HIV-uninfected partners. Antiretroviral-driven HIV-prevention strategies reduce risks of HIV transmission through pregnancy attempts and pregnancy. Programs to prevent or eliminate maternal-to-child-transmission (PMTCT/EMTCT) reduce perinatal transmission to less than 2% for women living with HIV [5]. Antiretroviral therapy (ART) extends the health and survival of people living with HIV (PLWH) to a life expectancy equivalent to that of HIV-negative persons [6, 7]. Furthermore, HIV prevention programs offer multiple approaches to reduce sexual HIV transmission risk during condomless sex [8, 9]: these can be promoted when people affected by HIV desire and attempt pregnancy.

A growing body of evidence suggests opportunities for widespread promotion of safer conception counseling and service delivery. Safer conception interventions reduce HIV incidence while supporting the pregnancy goals of men and women living with or affected by HIV. Safer conception program outputs dovetail with global goals to enhance HIV testing, ART uptake, and HIV-RNA suppression, and thus reduce HIV incidence and eliminate perinatal transmission. However, a limited number of country-level policies and a lack of global guidelines leave providers unprepared to counsel clients. Therefore, grounded in a reproductive rights-based framework, with foundations in scientific data and community values, we developed this consensus statement to: articulate experiences with and address growing demand for safer conception services; summarize the science; identify information gaps; outline research and policy priorities; and advocate for action.

History of Growing Consensus on Safer Conception

This consensus statement was motivated by discussions over the last decade. Safer conception research, policy, and implementation has been highlighted at international meetings [10,11,12,13,14,15] [16,17,18], leading journals have highlighted research in this field through supplements [19] [20, 21] [22], and several organizations advocate for and provide safer conception care for persons-affected by HIV [23] [24] [25]. The Global Network of People Living with HIV [15] and the International Community of Women Living with HIV [26] endorse safer conception programming and sexual and reproductive health and rights for people living with or affected by HIV. Canada [27, 28], South Africa [29], and the UK [30]) have national guidelines offering comprehensive safer conception guidelines.

Call for Consensus Document

The call for this global consensus statement to advocate for safer conception implementation emerged from a satellite session at the International AIDS Society 2015 Conference titled “Achieving pregnancy while minimizing HIV transmission risks: Safer conception research, policy, and programming priorities for HIV-affected individuals and couples” [31]. This session convened approximately 180 stakeholders from 25 countries including PLWH, clinicians, researchers, policy makers, community advocates, and donor agencies.

Our process

This document emerged from a consultative process incorporating input from the above meetings, literature, and discussions with key stakeholders. Three co-authors (LTM, RH, AK) developed a draft outline of the manuscript which was discussed and modified with co-authors and other experts in safer conception, HIV treatment and prevention, fertility, and perinatal transmission.

The updated outline informed a draft of the statement and feedback was sought from co-authors and key stakeholders (consumers, persons living with HIV, research and clinical leaders in safer conception). Feedback was integrated to develop a penultimate draft of the manuscript. All co-authors approved the final draft of the consensus guidelines. Subsequently, the statement was posted online and circulated to key stakeholders including organizations, clinicians, community members, researchers, and advocates in sexual and reproductive health, fertility, and HIV for endorsement (https://www.hiveonline.org/saferconceptionendorse/).

Consensus

We summarize the evidence regarding demand for, strategies for, and implementation of safer conception services. Several related topics such as contraception, antiretroviral treatment choices during pregnancy, perinatal transmission of HIV, and breastfeeding practices are not explicitly covered in this document. We outline key questions that remain unanswered and suggest steps for the way forward. We articulate the need for action to provide services to minimize pregnancy-related HIV transmission risks while supporting the sexual and reproductive goals of men and women affected by HIV. We urge providers and policy-makers to support safer conception service implementation even as research and advocacy continue.

Demand for Safer Conception Services: Evidence

For most men and women, an HIV diagnosis does not eliminate hopes or plans to have children, yet few access safer conception care [32,33,34,35]. Individual stories articulated by people living with HIV highlight the demand and opportunities for service delivery (See Box 1).

Box 1 Pregnancy experiences of HIV-affected men and women

The demand, opportunities, and challenges expressed in these stories echo throughout the literature. Most men and women living with or affected by HIV have limited awareness about HIV prevention options that reduce transmission during condomless sex [35, 36]. Providers do not initiate conversations about reproductive goals with HIV-affected clients [33, 35, 37,38,39] and anticipated stigma from providers is a barrier to seeking care [34, 40, 41]. In addition, individuals and couples who want to have children may not explicitly plan for pregnancy, limiting opportunities for pre-conception counseling [35, 42, 43]. HIV counseling and testing can be an entry point to discussions about pregnancy plans and safer conception care but uptake of pre-conception HIV testing is low [44]. Furthermore, this is not a one-time conversation, as reproductive goals evolve over time. For many seeking pregnancy, reproductive services and/or fertility evaluation may be necessary, but ongoing stigma and limited resources constrain access to fertility services for PLWH. Among those who know their serostatus, barriers to disclosure to sexual partners and confusion about serodiscordance limit recognition that conception attempts may be accompanied by HIV exposure [40, 45, 46]. When discussion about safer conception is started, provider guidance about the various methods is desired [47, 48]. Men’s voices are nearly absent in conversations about sexual and reproductive health for persons living with or affected by HIV [49]. Furthermore, many men and women make decisions and plans regarding reproductive goals together with families and communities where knowledge of safer conception opportunities is low. See Table 1 for summary consensus points in the area of Demand for Safer Conception Services.

Opportunities for HIV Prevention in the Context of Desired Pregnancy: Evidence

Several strategies allow HIV-affected couples to conceive with minimal transmission risk to the uninfected partner (Table 2). All PLWH, regardless of reproductive plans, are encouraged to initiate ART upon HIV diagnosis to improve their own health, reduce morbidity and mortality, and reduce HIV transmission [50]. When pregnancy is desired, the benefits of ART extend to safer conception. It is ideal for individuals and couples to delay pregnancy attempts until HIV-RNA is suppressed or after at least six months of ART [51, 52].

Table 2 Strategies to reduce periconception risk of HIV transmission for serodiscordant couples

Because uptake of and adherence to ART is often imperfect or unknown to the partner, individuals may choose additional methods to reduce transmission risk. Pre-exposure prophylaxis (PrEP) is recommended for those at substantial risk of HIV and is an important option for an uninfected partner wishing to conceive with an infected partner whose ART use is suboptimal or unknown [50]. For men or women exposed to HIV and not yet on PrEP, antiretroviral post-exposure prophylaxis (PEP) may reduce HIV acquisition risks and can be offered within 72 h of exposure and continued for 28 days after exposure [53] [50]. For individuals or couples exposed to HIV as part of conception attempts, PEP may be a bridge to PrEP [42]. When used prior to pregnancy, there are minimal safety or fertility concerns about tenofovir-based PrEP [54, 55]. For uninfected women, safety data about TDF/FTC-based PrEP during pregnancy are based on studies of women living with HIV or hepatitis B exposed to combination ART throughout pregnancy. The data are largely reassuring but inconsistent results suggest possible decreased bone mineral density in newborns, with unknown clinical significance, and one study showed risk of adverse infant outcomes (low birth weight or even stillbirth) among infants exposed to TDF/FTC as part of ART, a finding not replicated in other studies [55, 56]. This warrants additional data collection among women using PrEP throughout pregnancy. Current guidelines recommend PrEP as a safer conception strategy with discussion of the risks and benefits of continuing PrEP use during pregnancy and breastfeeding [50, 57].

Additional strategies to decrease HIV acquisition by men during pregnancy attempts with a woman living with HIV include vaginal self-insemination, which eliminates the need for condomless sex [58]; and medical male circumcision [59]. Treatment for sexually transmitted infections (STIs) has been shown to further reduce HIV transmission risk [60, 61]. Limiting condomless sex to days with peak fertility [62] maximizes likelihood of achieving pregnancy while limiting HIV exposure.

For HIV-serodiscordant couples where the man is living with HIV, sperm processing or “washing” can isolate sperm (which do not harbor HIV) from seminal plasma and leukocytes [63]. Processed semen can be introduced via intrauterine insemination, in vitro fertilization with or without intracytoplasmic sperm injection, or via a cervical cap. Robust data suggest that this process is safe and effective, with no recorded HIV transmissions to pregnancy partners [64]. This is an important option but should by no means be mandated [65].

Compromised fertility among HIV-affected couples may result in HIV-exposure with minimal chances of pregnancy [66]. Infertility screening may identify couples who would benefit from services to optimize fertility prospects prior to pregnancy attempts [67]. Comprehensive safer conception care also includes offering contraception until couples are ready to attempt pregnancy and/or once they have met their reproductive goals. See Table 1 for summary consensus points in the area of “Opportunities for HIV prevention in the context of desired pregnancy.”

Implementation of Comprehensive Sexual Reproductive Health Services: Evidence

Normative Guidance

Few countries have safer conception clinical guidelines. Canada, South Africa, and the UK have guidelines; however, many providers in these locations remain unprepared to counsel clients [35,36,37, 39, 41, 68, 69]. The WHO recommends ART for all PLWH and PrEP for HIV-exposed persons. Current global EMTCT guidance does not explicitly address safer conception programming.

Systems

Most safer conception services exist within specialized academic medical centers, private clinics, research projects, or privately funded implementation programs [42, 70,71,72,73]. Data show that where services are offered, uptake is high and outcomes are encouraging. These programs provide opportunity to inform future implementation efforts.

Reproductive Rights of People Living with HIV

A reproductive rights framework recognizes that all couples and individuals, including those living with or affected by HIV, have the basic right to “decide freely and responsibly the number, spacing, and timing of their children and to have access to the information, education, and means to do so” [74]. These rights also include the right to make reproductive decisions “free of discrimination, coercion, and violence”. The endorsement of the sexual and reproductive rights of PLWH is essential within safer conception guidelines, policies, and programs as a step towards building trust between providers and HIV-affected clients, given a history of sexual and reproductive rights violations of PLWH [75].

Legal and ethical issues present challenges to safer conception care delivery. Expectations that clients seeking pregnancy disclose HIV status to pregnancy partners must be considered in the context of clients’ lives and safety. Supporting safe disclosure is a component of safer conception programming, but not a prerequisite for participation. For many PLWH, particularly women, disclosure is highly challenging and in some cases dangerous—with risks of violence, relationship dissolution, and abandonment [76]. Disclosure challenges are exacerbated in settings where laws criminalize HIV non-disclosure, exposure, and/or transmission to sexual partners [77]. Institutionalized stigma and HIV criminalization are likely to influence willingness of HIV-affected individuals to engage and remain in HIV care [78] and safer conception care.

Providers

Providers rarely counsel clients about safer conception options [33, 35,36,37,38,39, 41, 68, 79,80,81]. In addition, many providers retain negative attitudes towards PLWH having children, in part due to experiences caring for children living with HIV, historical recommendations against pregnancy for PLWH, and lingering stigma and discrimination [36, 37, 39, 41, 81, 82]. After decades of focusing on condoms for HIV prevention, providers hesitate to endorse condomless sex [41, 81]. Provider time is limited and in demand. In addition, clients who want safer conception advice often hesitate to ask for it, in part due to the emphasis on condom use and perceptions of provider stigma towards pregnancy among PLWH [34, 40, 41, 82]. HIV-affected men and women may also seek care from traditional healers and other providers who may not have safer conception information [83, 84]. See Table 1 for summary points regarding Implementation of Comprehensive Safer Conception Services.

Key Questions Within the Areas of Demand, Opportunities for Prevention, and Implementation

We identified key questions within the areas of demand, opportunities for prevention, and implementation. Answers to these questions will improve care and implementation and inform policy, but need not delay service implementation.

Demand

How to reach at-risk, uninfected men and women who may benefit from safer conception services as well as PLWH not engaged in care or aware of their own or their partner’s serostatus is a gap. Normalizing pregnancy desires and pregnancy among people living with and affected by HIV is an outstanding goal to decrease stigma.

Prevention

The science of HIV prevention offers clear data regarding reduced risk of sexual transmission of HIV, but few methods have been studied in the context of couples or individuals seeking personal or partner pregnancy. Research to understand method use in the context of desired pregnancy is needed. While HIV-RNA suppression would ideally be confirmed prior to conception attempts, this is less feasible in resource-limited settings. 6 months is sufficient for the majority of clients to suppress HIV-RNA while taking effective ART. Strategies to test for suppression sooner for those eager to move forward with pregnancy attempts, or for those who feel more comfortable proceeding with proof of HIV-RNA suppression, are needed.

Tenofovir-based PrEP is a relatively new prevention technology and, accordingly, there are ongoing questions. A major challenge is how to best support adherence to PrEP [85]. In addition, there remain outstanding questions regarding the safety of TDF/FTC as prophylactic medication during pregnancy and breastfeeding [86]. Current WHO guidelines recommend PrEP as a safer conception strategy with discussion of the risks and benefits of use during pregnancy [50]—but some regional guidelines caution against use in pregnancy [87, 88]. Data to answer these questions are being collected [42, 72, 89]: how to counsel clients and providers to make informed decisions based on available and evolving data is needed [90].

Implementation

In early implementation studies, many clients seeking safer conception services have a medical history suggestive of infertility [91, 92]. How to support HIV-affected couples who have compromised fertility is a significant gap. Fertility evaluation after 6 months of timed unprotected sex has been recommended for HIV-negative women older than 35 years [93]. A similar approach has been advocated to minimize the duration of HIV exposure for HIV-affected couples, but there is not consensus about whether a fertility evaluation should be conducted prior to the couple’s attempts at achieving pregnancy, or at six or 12 months after attempted conception. A lack of available resources for fertility assessment and management should not preclude safer conception care [94] (Table 3).

Table 3 Resources

Safer conception options are required for those who are not ready for ART, who do not know partner HIV status, or whose partner is not engaged in care, on ART, or adherent. The consensus group agrees that combinations of methods are likely best, but which combinations and how many methods depends on the level of HIV risk, preferences of the individuals, and available services. The importance of balancing a public health approach (which may find PrEP cost-ineffective on top of ART for an infected partner) with personal risk assessment (for example, an individual may not feel confident that his or her partner is adherent to ART) is important to supporting clients while also attending to cost-effectiveness.

Questions regarding implementation are abundant. While ideally a diverse array of providers in HIV-endemic settings should provide these services, the reality is that services will first be offered by a smaller cadre of interested, motivated, or externally-funded providers. How to expand beyond providers with a particular interest in these services remains unclear. Community health workers may play an important role. How to integrate safer conception methods into existing paradigms (e.g. HIV care, sexual and reproductive health care) to leverage resources and maximize efficiencies is unknown. Provider tools that support provision of safer conception counseling and address stigma towards PLWH having children are also needed [82]. We also identified a need for systems to support providers offering care in settings where condomless sex without HIV disclosure among PLWH is criminalized [77, 78].

On the client level of implementation, how best to support safer conception programming for HIV-concordant-positive couples, men, same-sex couples, single parents by choice, extended and co-parenting families are outstanding questions. Ensuring that pregnancy planning and reproductive agency and autonomy are promoted within safer conception services and that providers support clients who want to have children but are not yet able to safely disclose to their partner, are outstanding gaps. How to create consumer-friendly services and tools is an area for future research.

Conclusions/Recommendations

It is time to implement safer conception services. This consensus is supported by science, consumer demand, and global goals to eliminate perinatal HIV transmission. We recommend that providers offer available safer conception services to HIV-affected men and women, and health program administrators integrate safer conception services into existing HIV and reproductive health programs. While the range of service choices may vary across settings, in all settings a minimal set of safer conception services is available. The most fundamental tenets of safer conception counseling are know your HIV-serostatus, know your partner’s HIV-serostatus, and wait until the partner living with HIV is on effective ART before attempting pregnancy. These basic tenets should be widely shared with HIV-affected persons, families, communities, and providers. We maintain that this work no longer needs to be the purview of specialists. Answers to outstanding questions will refine care, implementation, and policy but do not need to be resolved prior to offering services.

HIV-related stigma is a key barrier to uptake and delivery of safer conception care. People living with and affected by HIV who consider pregnancy or become pregnant and have children express internalized stigma and describe experiences of stigma from providers and community. Stigma compromises the willingness of clients to seek care and provider willingness to address reproductive goals with clients. It is imperative to acknowledge and support the sexual and reproductive rights of persons living with and affected by HIV and focus efforts on reducing stigma at individual-, provider-, and community-levels, such that HIV-affected men and women can make informed decisions and build healthy families.

We must develop tools that support HIV-affected persons to identify potential risk, engage with safer conception services, and use methods that align with preferences and level of risk. The goal is to engage all populations who could benefit from services including mutually-disclosed HIV-serodiscordant heterosexual couples, men and women living with or exposed to HIV, same sex couples, and seroconcordant-positive couples. Safer conception care must be flexible and address a diversity of clients.

We support development and implementation of strategies that can be adopted in diverse settings to support HIV-affected persons to achieve reproductive goals including increased access to ART and PrEP, HIV-RNA testing, STI testing, sperm washing and assisted reproductive technologies, and fertility care. Programs must be nimble in incorporating discussions about reproductive goals at many points in a client’s care without creating undue burden on providers or systems. Integrating safer conception messaging into public health targets for HIV prevention and treatment can maximize synergies.

Provider-initiated conversation is an important gateway to practicing safer conception. Providers across diverse disciplines and training-levels should be able to discuss reproductive options with HIV-affected couples and individuals. Tools to support providers to offer services are required, as are strategies and financing to support service integration [95].

Documenting the effect of safer conception is paramount for guidelines and for the confidence of providers and consumers. EMTCT and treatment as prevention initiatives dovetail with safer conception efforts. Data highlighting the advantages of these synergies may catalyze changes in policy and programs. Ensuring that the voices, values, preferences, and experiences of PLWH are at the forefront of safer conception messaging can normalize care-seeking and pregnancy in the context of HIV.

It is time to seize the opportunity to empower people affected by HIV to embrace their fertility goals and utilize safer conception strategies to satisfy goals for pregnancy with minimal HIV transmission risks. This group consensus is strongly supported by science, consumer demand, and global goals to reduce HIV incidence and eliminate perinatal transmission.
