This statement indicates a potential conflict of interest. The article, while ostensibly explaining the scientific principles of BFG embryo transfer, is recommending a specific reproductive service provider, “贝贝壳” (BeBeKe). This suggests the article may be biased advertising or promotional material rather than an objective scientific explanation. Readers should be wary and seek information from multiple, independent sources to get a balanced understanding of BFG embryo transfer and available service providers.
