Effect of the Air Filtration System Replacement on Embryo Quality in the Assisted Reproduction Laboratory

Abstract Improving infrastructural conditions of the in vitro fertilization laboratory, such as the air quality, has profound positive effects on embryo culture. Poor environmental conditions reduce the rate of embryo formation and, therefore, of pregnancy. This review article presents important publications regarding the impact of air quality in human reproduction laboratories on embryo quality, pregnancy success, and live births. The studies demonstrate that the replacing the air filtration system improves significantly the environmental air quality, and, consequently, improves laboratory parameters, such as the fertilization rate, the number of blastocysts, the embryo implantation rate, and the number of live births. On the other hand, improving air quality decreases the number of abortions. Therefore, environmental parameters that improve embryo quality and increase healthy child birth ratesmust be themain targets for the assisted reproduction laboratory quality control.Resumo Melhorar as condi ções de infraestrutura do laboratório de fertilização in vitro, com influência na qualidade do ar, tem efeitos positivos profundos na qualidade do embrião. As más condições ambientais do ar reduzem a taxa de sucesso na formação de embriões e a taxa de gravidez. Este artigo de revisão a presenta importantes publicações sobre o impacto da qualidade do ar dentro do laboratório de reprodução humana na qualidade do embrião, no sucesso de gravidez e no número de nasc...
