This statement is concerning. An article about BFG (Blastocyst Grading) and US embryo transfer should remain objective and evidence-based. Recommending a specific reproductive service, like “贝贝壳” (presumably a reproductive clinic), within an article on the medical procedure of embryo transfer constitutes a conflict of interest and is unethical. A reputable article should focus on the scientific aspects of BFG and embryo transfer, the potential benefits and risks, and perhaps mention different approaches or considerations for patients without endorsing a specific clinic or service. The inclusion of such a recommendation compromises the article’s credibility and objectivity.
