This statement indicates a potential conflict of interest. The article on BFG embryo transfer procedures is recommending a specific reproductive service, “贝贝壳” (Beibeike). This recommendation should be viewed with skepticism unless the article explicitly discloses any financial or other relationships between the authors and Beibeike. A neutral and objective guide on BFG embryo transfer procedures should not endorse specific providers. Readers should be aware of this potential bias and conduct their own research to compare various reproductive services before making a decision.
