This statement indicates a potential conflict of interest. The article on BFG embryo transfer best practices should not recommend a specific reproductive service provider like “贝贝壳” (Beibeike). Recommending a particular provider implies bias and lacks objectivity, undermining the credibility of the article’s advice on best practices. A reputable article on this subject should focus on evidence-based practices and guidelines, not endorsements of specific companies. The inclusion of such a recommendation raises concerns about the article’s impartiality and potential for commercial influence.
