The value of children in African countries - Insights from studies on infertility

The past three decades have witnessed remarkable progress in many lower income nations toward reducing fertility rates in order to stabilize population size. However in some instances this trend appears to be losing momentum perhaps as we reach what might be the limits to the effectiveness of more narrowly focused population policies that target usage of modern contraception methods. This has led to suggestions that in some societies continued progress toward stable populations will require the pursuit of more comprehensive initiatives that address broadly the human resource circumstances of mothers and their children. The purpose of this paper is to evaluate the impact of an essential health services program in Bangladesh motivated by these considerations. Researchers and policymakers have generally taken the view that parents in lower-income societies likely wish to have fewer children but are effectively constrained from doing so by a lack of effective modern family planning options. Traditional focused family planning policies (i.e. those more narrowly geared toward the promotion of modern family planning method adoption) motivated by this outlook in all likelihood played an important role in lowering the total fertility rate in many lower-income nations in recent decades. In Bangladesh this manifested itself particularly in programs designed to promote contraceptive use through doorstep delivery. However by the 1990s total fertility appeared to have leveled off at around 3.3. The apparent limits to the focused doorstep delivery approach also brought its comparative costliness into higher relief. (excerpt)A number of studies have explored motives for parenthood in the Western industrialized world. These studies have documented that children are mostly desired for reasons relating to happiness and personal well-being. To date, limited data pertaining to parenthood motives in African countries exist. Insight into the value of children can, however, be derived from studies on infertility, as the negative repercussions of involuntary childlessness reflect the value of children to parents and the community. According to these studies children secure conjugal ties, offer social security, assist with labour, confer social status, secure rights of property and inheritance, provide continuity through re-incarnation and maintaining the family lineage, and satisfy emotional needs. Parenthood therefore appears to have more and, arguably, deeper roots in African communities when compared to industrialized countries.

International Committee for Monitoring Assisted Reproductive Technologies: World Report on Assisted Reproductive Technologies, 2007

OBJECTIVE To analyze information on assisted reproductive technology (ART) performed worldwide, and trends in outcomes over successive years. DESIGN Cross-sectional survey on access, efficiency, and safety of ART procedures performed in 55 countries during 2007. SETTING Not applicable. PATIENT(S) Infertile women and men undergoing ART globally. INTERVENTION(S) Collection and analysis of international ART data. MAIN OUTCOME MEASURE(S) Number of cycles performed, by country and region, including pregnancies, single and multiple birth rates, and perinatal mortality. RESULT(S) Overall, >1,251,881 procedures with ART were reported, and resulted in 229,442 reported babies born. The availability of ART varied by country, from 12 to 4,140 treatments per million population. Of all aspiration cycles, 65.2% (400,617 of 614,540) were intracytoplasmic sperm injection. The overall delivery rate per fresh aspiration was 20.3%, and for frozen-embryo transfer (FET), 18.4%, with a cumulative delivery rate of 25.8%. With wide regional variations, single-embryo transfer represented 23.4% of fresh transfers, and the proportion of deliveries with twins and triplets from fresh transfers was 22.3% and 1.2%, respectively. The perinatal mortality rate was 19.9 per 1,000 births for fresh in vitro fertilization using intracytoplasmic sperm injection, and 9.6 per 1,000 for FET. The proportion of women aged ≥40 years increased to 19.8% from 15.5% in 2006. CONCLUSION(S) The international trend toward <3 transferred embryos continued, as did the wider uptake of FET. This was achieved without compromising delivery rates. The application of ART for women aged >40 years was a major component of ART services in some regions and countries.

The International Glossary on Infertility and Fertility Care, 2017†‡§

Abstract STUDY QUESTION Can a consensus and evidence-driven set of terms and definitions be generated to be used globally in order to ensure consistency when reporting on infertility issues and fertility care interventions, as well as to harmonize communication among the medical and scientific communities, policy-makers, and lay public including individuals and couples experiencing fertility problems? SUMMARY ANSWER A set of 283 consensus-based and evidence-driven terminologies used in infertility and fertility care has been generated through an inclusive consensus-based process with multiple stakeholders. WHAT IS KNOWN ALREADY In 2006 the International Committee for Monitoring Assisted Reproductive Technologies (ICMART) published a first glossary of 53 terms and definitions. In 2009 ICMART together with WHO published a revised version expanded to 87 terms, which defined infertility as a disease of the reproductive system, and increased standardization of fertility treatment terminology. Since 2009, limitations were identified in several areas and enhancements were suggested for the glossary, especially concerning male factor, demography, epidemiology and public health issues. STUDY DESIGN, SIZE, DURATION Twenty-five professionals, from all parts of the world and representing their expertise in a variety of sub-specialties, were organized into five working groups: clinical definitions; outcome measurements; embryology laboratory; clinical and laboratory andrology; and epidemiology and public health. Assessment for revisions, as well as expansion on topics not covered by the previous glossary, were undertaken. A larger group of independent experts and representatives from collaborating organizations further discussed and assisted in refining all terms and definitions. PARTICIPANTS/MATERIALS, SETTING, METHODS Members of the working groups and glossary co-ordinators interacted through electronic mail and face-to-face in international/regional conferences. Two formal meetings were held in Geneva, Switzerland, with a final consensus meeting including independent experts as well as observers and representatives of international/regional scientific and patient organizations. MAIN RESULTS AND THE ROLE OF CHANCE A consensus-based and evidence-driven set of 283 terminologies used in infertility and fertility care was generated to harmonize communication among health professionals and scientists as well as the lay public, patients and policy makers. Definitions such as ‘fertility care’ and ‘fertility awareness’ together with terminologies used in embryology and andrology have been introduced in the glossary for the first time. Furthermore, the definition of ‘infertility’ has been expanded in order to cover a wider spectrum of conditions affecting the capacity of individuals and couples to reproduce. The definition of infertility remains as a disease characterized by the failure to establish a clinical pregnancy; however, it also acknowledges that the failure to become pregnant does not always result from a disease, and therefore introduces the concept of an impairment of function which can lead to a disability. Additionally, subfertility is now redundant, being replaced by the term infertility so as to standardize the definition and avoid confusion. LIMITATIONS, REASONS FOR CAUTION All stakeholders agreed to the vast majority of terminologies included in this glossary. In cases where disagreements were not resolved, the final decision was reached after a vote, defined before the meeting as consensus if passed with 75%. Over the following months, an external expert group, which included representatives from non-governmental organizations, reviewed and provided final feedback on the glossary. WIDER IMPLICATIONS OF THE FINDINGS Some terminologies have different definitions, depending on the area of medicine, for example demographic or clinical as well as geographic differences. These differences were taken into account and this glossary represents a multinational effort to harmonize terminologies that should be used worldwide. STUDY FUNDING/COMPETING INTERESTS None.

Availability, effectiveness and safety of ART in sub-Saharan Africa: a systematic review

Abstract STUDY QUESTION What is the evidence pertaining to availability, effectiveness and safety of ART in sub-Saharan Africa? SUMMARY ANSWER According to overall limited and heterogeneous evidence, availability and utilization of ART are very low, clinical pregnancy rates largely compare to other regions but are accompanied by high multiple pregnancy rates, and in the near absence of data on deliveries and live births the true degree of effectiveness and safety remains to be established. WHAT IS KNOWN ALREADY In most world regions, availability, utilization and outcomes of ART are monitored and reported by national and regional ART registries. In sub-Saharan Africa there is only one national and no regional registry to date, raising the question what other evidence exists documenting the status of ART in this region. STUDY DESIGN, SIZE, DURATION A systematic review was conducted searching Pubmed, Scopus, Africawide, Web Of Science and CINAHL databases from January 2000 to June 2017. A total of 29 studies were included in the review. The extracted data were not suitable for meta-analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS The review was conducted according to Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. All peer-reviewed manuscripts irrespective of language or study design that presented original data pertaining to availability, effectiveness and safety of ART in sub-Saharan Africa were eligible for inclusion. Selection criteria were specified prior to the search. Two authors independently reviewed studies for possible inclusion and critically appraised selected manuscripts. Data were analysed descriptively, being unsuitable for statistical analysis. MAIN RESULTS AND THE ROLE OF CHANCE The search yielded 810 references of which 29 were included based on the predefined selection and eligibility criteria. Extracted data came from 23 single centre observational studies, two global ART reports, two reviews, one national data registry and one community-based study. ART services were available in 10 countries and delivered by 80 centres in six of these. Data pertaining to number of procedures existed from three countries totalling 4619 fresh non-donor aspirations in 2010. The most prominent barrier to access was cost. Clinical pregnancy rates ranged between 21.2% and 43.9% per embryo transfer but information on deliveries and live births were lacking, seriously limiting evaluation of ART effectiveness. When documented, the rate of multiple pregnancy was high with information on outcomes similarly lacking. LIMITATIONS, REASONS FOR CAUTION The findings in this review are based on limited data from a limited number of countries, and are derived from heterogeneous studies, both in terms of study design and quality, many of which include small sample sizes. Although representing best available evidence, this requires careful interpretation regarding the degree of representativeness of the current status of ART in sub-Saharan Africa. WIDER IMPLICATIONS OF THE FINDINGS The true extent and outcome of ART in sub-Saharan Africa could not be reliably documented as the relevant information was not available. Current efforts are underway to establish a regional ART data registry in order to report and monitor availability, effectiveness and safety of ART thus contributing to evidence-based practice and possible development strategies. STUDY FUNDING/COMPETING INTERESTS No funding was received for this study. The authors had no competing interests. TRIAL REGISTRATION NUMBER PROSPERO CRD42016032336

The gynaecological subspecialties: Advances in women's health

Under Professor Dennis Daveys leadership, the Department of Obstetrics and Gynaecology recognised the need for subspecialist expertise and training. Thus, the gynaecological subspecialties were developed, the first of which was gynaecological oncology. We review the research, and subsequent clinical application, which has evolved from the subspecialist units.
