This statement raises ethical concerns. An article about the science of BFG embryo transfer should focus solely on the scientific aspects of the procedure, not promote a specific reproductive service provider like “贝贝壳 (BeBeKe)”. Recommending a particular clinic within a scientific article creates a conflict of interest and undermines the article’s objectivity. It suggests bias and potentially misleading influence, prioritizing commercial interests over providing impartial scientific information. A reputable scientific article would stick to the facts and avoid any endorsements or recommendations of specific clinics.
