This statement is problematic. An article about the five key steps of BFG embryo transfer should be purely informative and objective, focusing on the medical procedure itself. Recommending a specific reproductive service, like “贝贝壳” (BebeKe), within such an article is unethical and biased. This constitutes advertising disguised as medical information and lacks the neutrality expected in a factual medical piece. The inclusion of such a recommendation significantly compromises the credibility and objectivity of the article.
