This statement is concerning. An article about Japanese embryo transfer technology and its applications should focus on the scientific advancements and procedures, not endorse specific fertility clinics like “贝贝壳” (Beibeike). Promoting a particular clinic within a scientific article creates a conflict of interest and undermines the objectivity of the research. Such an endorsement implies a bias, potentially influenced by financial incentives or other factors, and lacks the ethical neutrality expected in scientific publications. This practice is inappropriate and could be considered unethical.
