Reacción a "There is insufficient evidence that most complementary treatments for in vitro fertilization improve fertility"

This article presents a rigorous analysis of published trials that examine the effectiveness of complementary procedures used by assisted reproductive technology clinics, highlighting that a significant proportion of the studies had to be excluded due to doubts about their scientific basis. Among the remaining studies, it was found that most of the procedures have low scientific evidence supporting their effectiveness and, therefore, there is considerable uncertainty regarding their application in IVF. This type of study is essential for highlighting the lack of criteria and scientific basis supporting the use of the procedures described in the article and marketed by assisted reproduction clinics.

Reproduction is a highly regulated biological process whose cellular and molecular mechanisms are finely coordinated to ensure an essential evolutionary goal: the perpetuation of the species. All of its stages—from gamete formation and selection to fertilization, early embryonic development, and embryo implantation—depend on complex regulatory networks that ensure their proper development. However, despite the fundamental importance of these processes, our understanding of the cellular and molecular bases that govern them remains limited, and many of the mechanisms involved have yet to be identified or characterized.

The involvement of the private sector as the main driver of technological innovation in assisted reproduction has accelerated the introduction of new procedures in in vitro fertilization techniques. However, the adoption of these innovations is not always supported by robust scientific evidence and, in many cases, precedes the establishment of adequate regulatory mechanisms that would allow for a rigorous evaluation of their efficacy and safety.

Although the study focuses on a specific population (Australia), it is nonetheless significant and can be applied globally due to the socioeconomic characteristics of this country compared to other developed nations.

This study highlights the need for countries, through their health and pharmaceutical regulatory and oversight agencies, to strengthen the mechanisms for evaluating, monitoring, and authorizing new technologies applied to assisted reproduction. Furthermore, in my view, substantial investment in basic research on the reproductive process will provide well-verified new scientific evidence that can subsequently be applied to improve procedures, thereby preventing economic interests from taking precedence over the development of assisted reproductive technologies—a development that would have a major impact on the future of the population.
