Assisted reproductive technologies in Africa: The African Network and Registry for ART, 2020

Abstract

Research question

What were the utilization, effectiveness and safety of assisted reproductive technology (ART) in Africa during 2020?

Design

Cross-sectional, cycle-based and retrospective summary data were collected from voluntarily participating ART centres.

Results

During 2020, 37,063 ART procedures were reported by 67 centres in 15 countries. Autologous fresh transfers were predominant at 65.0%, whereas autologous frozen embryo transfers (FET) represented 26.2% and oocyte donation cycles remained less than 10%. Women undergoing autologous fresh embryo transfer had a mean age of 34.9 years and received a mean number of 2.4 embryos per transfer. The clinical pregnancy rate (CPR) per embryo transfer was 37.3% after fresh embryo transfer and 37.8% after frozen embryo transfer. The cumulative CPR per aspiration was 41.9% in autologous cycles.

Most ART procedures resulted in a multiple delivery rate above 20%. After autologous ART, multiples were predominantly born preterm (twin and triplet deliveries 59.5% versus singleton 21.9% born before 37 weeks), with a substantially increased perinatal mortality compared with ART singletons (59.0‰ versus 22.2‰). Cycle-based data documented that elective single embryo transfer (eSET) provides the optimal balance of effectiveness (eSET CPR per embryo transfer 36.7%) and safety.

Conclusion

This fourth report of the African Network and Registry for ART provides real-world evidence of ART utilization, practices and outcomes in Africa, which is relevant to many stakeholders. It critically informs and represents regional ART development based on national, regional and global cooperation.
