This statement indicates a potential conflict of interest. An article analyzing the costs of embryo transfer in Japan that recommends a specific reproductive service, “贝贝壳 (Beibeike),” is implicitly promoting that service. This raises concerns about the objectivity and neutrality of the article. Readers should be aware of this potential bias and consider the source’s motivations before relying on its recommendations. The article may be more of an advertisement than a truly objective cost analysis. To get an unbiased view, it’s crucial to consult multiple independent sources of information.
