Ethical concerns for maternal surrogacy and reproductive tourism

Reproductive medical tourism is by some accounts a multibillion dollar industry globally. The seeking by clients in high income nations of surrogate mothers in low income nations, particularly India, presents a set of largely unexamined ethical challenges. In this paper, eight such challenges are elucidated to spur discussion and eventual policy development towards protecting the rights and health of vulnerable women of the Global South.

Measuring reproductive tourism through an analysis of Indian ART clinic Websites

Objectives: India is fast becoming the most prominent player in the global industry of reproductive tourism, in which infertile people cross international borders to seek assisted reproduction technologies. This study was conducted to better understand the extent and manner in which Indian clinics seek foreign clients. Methods: A systematic search of official Indian assisted reproduction technologies clinic Websites was undertaken, and instances noted where foreign clients were overtly targeted, and where maternal surrogacy was overtly offered. Results: A total of 159 clinics with Web addresses were identified, though only 78 had functioning Websites. All were published in English, with the majority clustered in the states of Maharashtra (14) and Gujarat (9). Of the 78 functioning Websites, 53 (68%) featured some mention of maternal surrogacy services, and 42 (54%) made overt overtures to foreign clients. Qualitative appeals to foreigners included instructions for international adoption, visa application, and the legal parental disposition of the surrogate. All Maharashtran clinic Websites that mentioned surrogacy also overtly featured reproductive tourism. Preimplantation diagnosis services were not offered disproportionately by clinics mentioning reproductive tourism. Conclusions: Based upon clinic online profiles, reproductive tourism comprises a substantial fraction of India’s assisted reproduction technologies clinics’ business focus, clustering around its most tourist-friendly locales, and surrogacy may be a strong motivator for international clientele.

Recent trends in reproductive tourism and international surrogacy: ethical considerations and challenges for policy.

Reproductive tourism, or “cross-border reproductive care”, is the phenomenon of people crossing international borders to access reproductive technologies. One of the fastest-growing categories of cross-border reproductive care is international surrogacy, the act of infertile clients traveling internationally to engage the paid services of foreign surrogates to carry their babies to term. It is a multibillion-dollar global industry presenting unique legal, ethical, and risk-management challenges. Clients tend to be price-sensitive, middle-income individuals seeking services from surrogates who in the global market are thought to be of quite low socioeconomic status. Risks are experienced by all parties involved in the transaction, including the client’s countries of origin and destination. The risks to the surrogate evolve from the potential to exploit her economic vulnerability in order to encourage both consent and unfair pricing. Opportunities for policy development are explored.

Women exposure during pregnancy to haloacetaldehydes and haloacetonitriles in drinking water and risk of small-for-gestational-age neonate

BACKGROUND Past studies have examined the effects of maternal exposure to water chlorination disinfection by-products (DBPs), such as trihalomethanes (THMs) and haloacetic acids (HAAs) during pregnancy. However, no human-based study has yet evaluated the effect of emerging DBPs, such as haloacetaldehydes (HAs) and haloacetonitriles (HANs) on small-for-gestational-age (SGA) status in newborns. OBJECTIVE This study aims to assess the association between maternal multiroute exposure to HAs and HANs during the third trimester of pregnancy and SGA status at birth, among neonates delivered by women residing in the Quebec City area (Province of Quebec, Canada). We also evaluated the interaction between exposure to these emerging unregulated by-products and regulated DBPs also found in drinking water (THMs and HAAs), for which a positive association with adverse reproductive outcomes has been suggested in previous studies. METHODS We conducted a population-based case-control study in the Quebec City area. SGA newborns (n=330) were compared to 1100 controls, with matching based on calendar week of birth. HA and HAN concentrations in drinking water at participants tap were estimated using spatio-temporal strategy based on bimonthly measurements carried out at several locations in the participants distribution system. A computer-assisted telephone interview was completed to collect information on individual habits of water consumption and water related activities in order to determine individual multiroute exposure. This enabled us to estimate the dose of HAs and HANs absorbed daily by each participant. Associations between total HA, HAN concentrations in drinking water and SGA were analyzed. Associations between the daily-absorbed doses of these emerging DBPs and SGA were also analyzed. Odds ratios (ORs) comparing the 4th quartile of exposure to the reference group (the first three quartiles) were obtained by means of conditional logistic regression, and controlling for potential confounders. RESULTS Globally, no evidence of increased risk of SGA was found with total HA and HAN concentrations in tap water when participants in the 4th quartile of exposure were compared to the first three quartiles (OR=1.0; 95% CI [0.7-1.5] and OR=0.8; 95% CI [0.6-1.2], respectively). Similarly, no association was found with the daily-absorbed doses of total HAs or HANs (OR=0.9; 95% CI [0.6-1.3] and OR=1.1; 95% CI [0.7-1.6], respectively). However, a small non statistically significant association was found between the dose of brominated HA and SGA (OR=1.4; 95% CI [0.9-2.1]). Also, in spite of the lack of interaction between other DBP classes, an unexpected negative interaction was observed between concentration of chloral hydrate (CH) (which represents the main HA species), and regulated DBPs (P=0.006). CONCLUSION In this population, exposure to low levels of HAs and HANs during the third trimester of pregnancy through drinking water was not associated to SGA status in newborns. Nonetheless, more research is needed to clarify possible effect of brominated compounds and interaction between different DBPs.

Global decline in semen quality: ignoring the developing world introduces selection bias

Multiple studies from around the world have suggested that semen quality is declining globally. However, all studies suffer from variable semen sampling criteria, selection bias with respect to the types of men volunteering to participate, and a bias with respect to a tendency to examine only samples from high-income countries. This heterogeneity in approaches, especially given the undersampling of rural and less affluent men from low-income countries, calls into question researchers’ claims of universally declining semen norms.

A pilot study: research poster presentations as an educational tool for undergraduate epidemiology students.

Students in a fourth year epidemiology course were surveyed after participating in a formal Science Research Day in which they presented original research, in poster form, to be judged by scientists from the community. Of 276 participating students, 80 (29%) responded to the study survey. As a result, 19% of respondents were more likely to pursue a career in science, and 27.5% were more likely to pursue a career in epidemiology. Only one respondent reported being less likely to pursue a science career, while seven were less likely to pursue epidemiology. A majority of respondents felt that the poster experience was on par with, or superior to, a comparable research paper, in terms of both educational appeal and enjoyment. Mandatory, formal poster presentations are an innovative format for teaching advanced health sciences, and may more accurately reflect the realities of a science career than do more traditional educational formats.

Assisted Reproduction and Cross-Border Maternal Surrogacy Regulations in Selected Nations

Aims: To ascertain the laws and policies of selected high income countries, with respect to the disposition of their citizens seeking assisted reproductive technologies (ARTs) internationally. Study Design: Literature review. Methodology: PubMed, Scopus and Google of various ART terms with terms relating to regulations in the selected nations of Australia, Canada, New Zealand, the UK, the USA, and Israel. Results: All nations except the USA have a federal ART regulatory presence, distinguish between gestational and traditional surrogacy, and between paid and unpaid surrogacy. Policies concerning the repatriation of children produced by ART abroad vary widely. Conclusions: Heterogeneous regulations are one of the drivers of the global reproductive tourism industry. Domestic regulations are likely affected by both the values of a specific population and the needs of the industry.

Driving deaths and injuries post-9/11

Objectives In the days immediately following the terror attacks of 9/11, thousands of Americans chose to drive rather than to fly. We analyzed highway accident data to determine whether or not the number of fatalities and injuries following 9/11 differed from those in the same time period in 2000 and 2002. Methods Motor crash data from the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System were analyzed to determine the numbers and rates of fatalities and injuries nationally and in selected states for the 20 days after September 11, in each of 2000, 2001, and 2002. Results While the fatality rate did not change appreciably, the number of less severe injuries was statistically higher in 2001 than in 2000, both nationally and in New York State. Conclusions The fear of terror attacks may have compelled Americans to drive instead of fly. They were thus exposed to the heightened risk of injury and death posed by driving. The need for public health to manage risk perception and communication is thus heightened in an era of global fear and terrorism.

Health professionals in the 21st century: results from an inter professional and multi-institutional global health competencies survey (a pilot study).

Introduction:In the new century, worldwide health professionals face new pressures for changes towards more cost-effective and sustainable health care for all populations. Globalization creates daunting challenges as well as new opportunities for institutions and health professionals being more connected and rethink their strategies toward an interprofessional practice. Although Health professionals are paying increased attention to issues of global health, there are no current assessment tools appropriate for evaluating their competency in global health. This study aimed to assess global health competencies of family medicine residents, nursing, physiotherapy and occupational

A student-run peer-reviewed journal: an educational tool for students in the health sciences.

Students at the University of Ottawa, many of whom were targeting a career in medicine, were surveyed to determine their attitudes and expectations regarding a new student-run peer-reviewed journal for the health sciences. A number of students reported that the existence of the journal would make them more likely to take a class with a written component, while a majority would work harder on that assignment. Those intending to pursue postgraduate or professional studies were most likely to recognize the value to their careers of having a publication history. We argue that student-run medical communication endeavors such as this are beneficial both for enhancing student careers and for contributing to a more thorough educational experience.
