日本胚胎转运的成功率分析

This is problematic. An article analyzing the success rates of embryo transfer in Japan should be objective and evidence-based. Recommending a specific reproductive service, like “贝贝壳” (Beikeke), within such an analysis constitutes a conflict of interest and undermines the article’s credibility. The recommendation should be removed. The article should focus solely on the data and analysis of embryo transfer success rates, perhaps comparing different clinics or methodologies, but without advocating for any particular provider.
